Installing SQL Anywhere Professional on Windows NT -------------------------------------------------- Before installing NetImpact Dynamo, you should ensure that no third party services are running, such as Netscape Enterprise Server or the Microsoft World Wide Web Publishing Service. You can stop these services from the Services icon in the Control Panel. To install SQL Anywhere Professional on Windows NT you must be logged on as a user with administrative privileges. After installing NetImpact Dynamo, a dialog box will open asking you if you wish to modify your environment variables. These changes need to be made to the local machine variables, not the current user variables. By default, the changes are made to the local machine variables. =============================================================================== Contents -------- 1.

DOS and Windows 3.x I/O -------------------------- The default I/O method for DOS and Windows 3.x standalone engines and network servers is now DOS I/O rather than direct I/O. The -d command line switch is supported, but ignored. If you are a user of Watcom SQL 4.0 with a large database running on Windows 3.1 or on Windows 3.11 without 32-bit disk access, you may want to use a new command-line switch, -di, which means "use direct I/O if possible". More documentation can be found in the online Help, but not in the printed manual. 2. Documentation corrections ---------------------------- Some of the following corrections to the printed User's Guide have been made in the online Help. The online Help is generally more up to date than the printed documentation. 2.1 GRANT REMOTE syntax ----------------------- The syntax of the GRANT REMOTE and GRANT CONSOLIDATE SQL Remote statements does not include the optional SEND AT and SEND EVERY clause. See the online Help and the section "Granting and revoking REMOTE and CONSOLIDATE permissions" in the chapter "SQL Remote Administration" for a description of these clauses. 2.2 Long binary and long varchar types in Embedded SQL ------------------------------------------------------ In the section "Length field values" in the chapter "Embedded SQL", the table states that the database field type LONG BINARY is returned as an Embedded SQL type DT_LONGBINARY. In fact, it is returned as DT_BINARY. Similarly, LONG VARCHAR is returned as DT_VARCHAR. 2.3 System procedures ---------------------- You may wish to correct the following typographic errors in your copy of the User's Guide: p 1124: The failure code for xp_startmail is 3. p 1125: The correct argument for xp_sendmail is include_file, not include-file. p 1127: The failure code for xp_stopmail is 2. 2.4 Using xp_startmail with Microsoft Exchange ---------------------------------------------- When using the xp_startmail system procedure with Microsoft Exchange, the mail_user parameter is an Exchange profile name, and no password should be included in the procedure call. 2.5 Network Server -i command-line switch ----------------------------------------- Pages 60 and 64 of the Network Guide describe the database server -i command-line switch as disconnecting clients after a specified idle time. The -i command-line switch for the network server disconnects connections (not clients) that have not submitted a request for the specified number of minutes. 3. The quoted_identifier option and SQL keywords ------------------------------------------------ The quoted_identifier option is a database option introduced for Transact-SQL compatibility. With the quoted_identifier option set to ON (the default), keywords can be used as identifiers if surrounded by double quotes. With the quoted_identifier option set to OFF, the engine treats strings in double quotes as strings. If you use quoted_identifier set to OFF, you must avoid using keywords as identifiers or be prepared to flip the setting to ON temporarily. If you set quoted_identifier to OFF, and issue a SET statement in ISQL, only a subset of the options is displayed. This is because the SET statement references a table with a column named "option". which is a keyword. We recommend that you use quoted_identifier ON wherever possible. The quoted_identifier option should be used as a mechanism to allow existing queries that use double quotes to work. 4. External procedure changes ------------------------------ Calling functions in external libraries from stored procedures is discussed in the chapter "Procedures, Triggers, and Batches". The following changes should be noted. 4.1 Calling functions in NLMs ---------------------------- When a function in a NLM is called, only loaded NLM's are searched for the function. The database engine does not search or load NLM's that are currently not loaded. 4.2 Argument order in Windows 3.x DLLs -------------------------------------- The calls to functions in Windows 3.x DLLs can employ the cdecl calling convention, as opposed to the default Pascal calling convention. To use the cdecl calling convention, in which parameters are passed in right to left rather than left to right, use the VARARGS keyword, as in the following syntax: CREATE PROCEDURE dll_proc ( parameter-list ) EXTERNAL NAME 'Windows3X:function_name[varargs]@library.dll'; 5. Note for users of the Open Server Gateway for NetWare -------------------------------------------------------- Before loading the Open Server Gateway for NetWare (DBOS50.MNLM) you must ensure that certain symbols are defined and required libraries are loaded. You should ensure that the following tasks are complete before loading DBOS50.NLM: o Add the Sybase NLMs directory to the search path. The following command carries out this task: search add sys:\sybase\nlms o Add the Sybase install directory to the search path for Sybinit purposes. The following command carries out this task: search add sys:\sybase\install o Load the NetWare Transport Level Interface Library provided by Novell. The following command carries out this task: load tli.nlm o Load the Sybase LIBSRV NLM. The following command carries out this task: load libsrv.nlm You can now load the SQL Anywhere Open Server Gateway. 6. Known bugs and limitations ----------------------------------- 6.1 Log Translation utility (DBTRAN) output and character sets -------------------------------------------------------------- Output from the log translation utility that includes binary data, such as encrypted passwords, cannot be run from Windows ISQL. 6.2. SQL Central limitations ---------------------------- You can carry out almost all database administration tasks with the SQL Central database administration tool. The following are known limitations of SQL Central: 6.2.1 Administrative tasks -------------------------- The rebuild, dbcollat, and dbinfo command-line tools are not available in SQL Central. You cannot pre-extend the transaction log file. 6.2.2 Users and groups ---------------------- You cannot make a user into a group, or vice versa. 6.2.3 Miscellaneous limitations ------------------------------- You cannot use single or double quotes in entry fields. For example, user names with apostrophes (Dave O'Brien) are not supported. SQL Central should not be used on a Watcom SQL 4.0 database engine; instead use the SQL Anywhere 5.0 engine to connect to pre-5.0 databases. When creating foreign keys CHECK ON COMMIT can be selected for non-RESTRICT actions (but is harmless). 6.3 Dynamo limitations ---------------------- When copying a database to a new computer, the ODBC data source name must be exactly the same as specified on the original computer. To ensure that it is the same, open the Connections folder, select the "default" connection, open the Properties window, and select the new ODBC data source name from the drop down list. 7. Behavior change in Release 5.0 ---------------------------------- The SQLSTATE for the error TABLE_NOT_FOUND has been changed from 52W01 to 42W33, to conform to the ANSI92 standard. 8. About Release 5.0.01 ----------------------- 8.1 Numbering scheme -------------------- Sybase SQL Anywhere uses numbers to indicate patch or maintenance-level releases. Release 5.0.01 is the first maintenance-level release for Sybase SQL Anywhere 5.0. The numbering scheme replaces the alphabetic scheme used for Watcom SQL patch-level releases. 8.2 In release 5.0.01 --------------------- Release 5.0.01 is being released to address some problems in the initial 5.0 release, particularly a backwards-compatibility problem. The backwards-compatibility problem applies only to databases initialized with Watcom SQL 4.0 or earlier. During recovery following a system failure or other improper database shutdown, the 5.0 database engine does not process the transaction log for databases initialized with Watcom SQL 4.0 or earlier. Consequently, committed transactions made between the most recent checkpoint and shutdown are not recovered for these databases. Release 5.0.01 fixes this problem. 9. About Release 5.0.02 ----------------------- This section lists new features in Release 5.0.02, with pointers to the online Help for more information. To locate a topic in the online Help, goto the index or search facility and type the topic name. Some of the new features involve changes to the system tables, and are accessible only if you upgrade your database, using the SQL Central Upgrade wizard or the DBUPGRAD command-line utility. CREATE SCHEMA statement Creates a collection of tables, views, and associated permissions for a user. For information, see "CREATE SCHEMA statement". in the online Help index. FLOAT( P ) data type Stored as REAL or DOUBLE, depending on the value of P. SQL Central does not allow you to create columns using the FLOAT( P ) data type. For information, see "Numeric data types" in the online Help index. Foreign keys More than one unnamed foreign key per table can now be created. For information, see "CREATE TABLE statement" in the online Help. GRANT statement SELECT and REFERENCE permissions can now be granted on a column by column basis, and permissions on views can be granted by users other than the DBA. For information, see "GRANT statement" in the online Help index. To take advantage of the new permission features, you must upgrade your database using the SQL Central Upgrade Wizard or the DBUPGRAD command-line utility. Column default extension Constant expressions are now allowed as column defaults, as long as they do not reference database objects. For information, see "CREATE TABLE statement" and "Constant expression defaults" in the online Help index. SQL Anywhere Service Manager extensions SQL Anywhere NT services can now be configured to not interact with the NT desktop. For information, see "Adding a new SQL Anywhere service" in the online Help index. NT Service examples Sample Embedded SQL and ODBC applications in C are provided that can be run as an NT service from the Service Manager. For information, see "NT Service examples" for the Embedded SQL example and "The sample program" for the ODBC example in the online Help index. New engine and server switches The -m command-line switch truncates the transaction log after each checkpoint, for situations where the transaction log is not required for recovery and disk space is a concern. With the -u switch, the engine or server uses the operating system disk cache. This switch is available for the Windows 95 and Windows NT engine and server only. The HOST network communications option (-x switch) on the Windows 95 and Windows NT server can be used on IPX networks to locate servers on specific machines. For information on new engine and server switches, see "The database engine" in the online Help index, and "The database server" in the online Server Manual. New database options The NON_KEYWORDS option allows you to avoid incompatibilities introduced by new keywords. For information, see "SET OPTION Statement" in the online Help index. The ANSI_BLANKS option forces a truncation error if a CHAR(N) value is read into a char(M) C host variable, and N is greater than or equal to M. For information, see "SET OPTION Statement" in the online Help index. Transact-SQL support CREATE TABLE and CREATE INDEX now support the ON segment-name clause. CREATE INDEX permits the CLUSTERED and UNCLUSTERED keywords, although no clustering is performed. For information, see "Transact-SQL CREATE INDEX statement" and "Transact-SQL CREATE TABLE statement" in the online Help index. The GOTO control of flow statement is now supported. For information, see "Transact-SQL GOTO statement" in the online Help. The system objects owned by the DBO user ID are now not unloaded by either the Unload or Extraction utilities. For information, see "The Unload utility" and "The SQL Remote database extraction utility" in the online Help index. Client/Server timeout management For client/server connections to the network server, a set of server and client switches have been introduced to control the closing down of inactive connections. For information, see "The database server" and "The SQL Anywhere Client" in the online Server Help file. Multiple-event triggers A single trigger can now be defined to handle a combination of INSERT, UPDATE, and DELETE operations on a table. For information, see "CREATE TRIGGER Statement" in the online Help index. Escape character for loading and unloading data The escape character for loading and unloading data can be changed from its default value of the backslash. For information, see "LOAD TABLE statement", "UNLOAD TABLE Statement", "INPUT Statement", "OUTPUT Statement", "Unload utility options", and "Extraction utility options" in the online Help index. Support for Borland C++ SQL Anywhere now supports Borland C++ 4.5 as a development compiler for the Windows NT platform. For information, see "Supported Compilers" in the online Help index. SQLSTATE/SQLCODE can be declared For ISO/ANSI compliance, you can declare SQLSTATE and SQLCODE as host variables within a declare section of a C program. For information, see "Host variable usage" in the online Help index. CREATE/DROP DOMAIN as alternative to CREATE/DROP DATATYPE The keyword DOMAIN is a synonym for DATATYPE in the CREATE/DROP DATATYPE statements. The use of DOMAIN reflects the ANSI/ISO SQL3 draft standard. For information, see "CREATE DATATYPE statement" in the online Help index. ISQL START DATABASE statement The ISQL START DATABASE statement now has an optional AUTOSTOP clause. For information, see "START DATABASE statement" in the online Help index. Beta release of new SQL Remote message types DLL's are provided for SMTP and VIM message type support in SQL Remote. These are provided as beta pre-release versions. SMTP support is provided for the Windows 95, 3.x, and NT, while VIM support is provided for Windows 3.x only. SQL Central enhancements SQL Central shows all running databases on a server, not just connected databases. You can start and stop databases on a server. You can create global temporary tables. The enhancements to object permissions, including grant options, are accessible from SQL Central. You can create user accounts with no password. SQL Remote users now have a statistics page. A Create Table wizard has been added. 10. About Release 5.0.03 ----------------------- 10.1 Behavior change ------------------- When an INSERT or UPDATE truncates a CHAR or VARCHAR string, previous versions of SQL Anywhere and Watcom SQL truncated the string silently, and did not generate an error. A new default behavior corresponds to ANSI/ISO SQL/92 behavior, and raises an error when entries are truncated. 10.2 New features ---------------- This section lists new features in Release 5.0.03, with pointers to the online Help index for more information. To locate a topic in the online Help index, goto the index or search facility and type the topic name. SQL Remote enhancements Subqueries in publications can be used in a broader range of situations. If a row in a table is updated so as to "move" from one subscription to another, you can now ensure that all rows in foreign key tables are also moved, by using a new syntax for the UPDATE statement. For information, see "UPDATE Statement" and "Using subqueries in publications". Subqueries in SUBSCRIBE BY clauses can now return more than a single value, so that rows can appear in more than one subscription. For information, see "SUBSCRIBE BY subqueries returning multiple values" in the online Help index. The Message Agent (DBREMOTE) has a new command-line switch (-l) to control the maximum length of messages. For information, see "The SQL Remote Message Agent" in the online Help index. VIM and SMTP message support is now available for each of OS/2, Windows 3.x, Windows 95, and Windows NT. Registry entries and initialization file entries are available for control over some aspects of SQL Remote message links. DBSTOP can stop the server The DBSTOP utility can be used to stop the server. The permission required to stop a standalone engine or network server can be set using the new -gk engine or server command-line switch. For information, see "The database engine" in the online Help index, and "The database server" and "Stopping the database server executable" in the online Network Guide. New engine and server switches The new -ta command-line switch for the database engine, server, and client control the disconnection of connections from terminated applications. This termination prevents applications that crash from holding on to a connection for longer than a specified time. For information, see "The database engine" in the online Help index, and "The database server" and "The SQL Anywhere Client" in the server online Help index DESCRIBE statement A new clause has been added to the DESCRIBE statement to retrieve column names with more than thirty characters. For information, see "DESCRIBE statement" in the online Help index. Procedures with different-shaped result sets A new clause on the DESCRIBE statement allows different-shaped result sets to be used within a procedure. For information, see "DESCRIBE statement" in the online Help index. To take advantage of this facility, ODBC developers should delay calling SQLDescribeCol until after they have executed the statement, instead of calling it after the statement is only prepared. SQL Central enhancements SQL Central has context-sensitive help. SQL Central allows altering of views and triggers. For details, see "ALTER TRIGGER statement" and "ALTER TRIGGER statement" in the online User's Guide. Wizards are now provided to help you write views and stored procedures. The code editor now has Find, Replace, and Go To facilities, and also options to control the display font. Support for users without DBA authority has been improved. ANSI/ISO option The STRING_RTRUNCATION option allows control over generation of an error when an INSERT or UPDATE truncates a character string. For information, see "SET OPTION statement" in the online Help. ALTER VIEW and ALTER TRIGGER statements These new statements allow an existing view or trigger definition to be replaced by a new definition. For details, see "ALTER TRIGGER statement" and "ALTER VIEW statement" in the online Help index. Transact-SQL accepted by parser To enhance SQL Server compatibility, performance parameters that can be used in SELECT, UPDATE, and DELETE statements in System 11 are now accepted and discarded by SQL Anywhere. Also, the PREFETCH System 11 option is allowed, but has no effect. ISO/ANSI SQL/92 flagging The embedded SQL preprocessor supports command-line switches that flag SQL statements not conforming to entry, intermediate, or full SQL/92 with an error or warning. For information, see "The SQL Preprocessor" in the online Help index. Two database options are available that flag non-conforming SQL syntax in the same way within the database engine. For information, see "database options" in the online Help index. Open Server Gateway enhancements Several enhancements have been made to improve SQL Server compatibility: The Open Server Gateway has more complete datatype support. It supports numeric and decimal datatypes, and datatype conversions based on the capabilities of the application. Improved text and image support have been added to support replication and to support DBLIB and CTLIB applications that use text and image API calls. Improved cursor API support has been added. New Embedded SQL function The db_interface_option function has been added. It has the form: void db_interface_option( struct sqlca *sqlca, int option, long value ) The db_interface_option() is an Embedded SQL function used to set database interface options. Currently there is only a single option, DBO_ANSI_TRUNCATION. The DBO_ANSI_TRUNCATION option specifies how to set indicator variables in the case of string truncation. If DBO_ANSI_TRUNCATION is set to 0, indicator variable values include the null char when indicating the size of the truncated string. Set DBO_ANSI_TRUNCATION to 1 to get ANSI/ISO behaviour, which is to not include the null char when indicating the size of the truncated string. The default value for DBO_ANSI_TRUNCATION is 0, for backwards compatibility. 11. About Release 5.5 --------------------- With release 5.5, Sybase SQL Anywhere can be obtained in a Standard and a Professional Edition. The Professional Edition includes additional components. In particular, the following components are included in the Professional Edition: o NetImpact Dynamo Internet features o The Powersoft InfoMaker reporting tool To mark the availability of the new versions, and the new features included in the Professional Edition, the version number of this release of the software is 5.5. For last-minute information about Powersoft InfoMaker, see the InfoMaker Read Me First, installed into your program group. The last-minute information about NetImpact Dynamo, below, is also included in NetImpact Dynamo online Help, installed into your program group. 11.1 Behavior changes --------------------- When an arithmetic operation results in an integer overflow, the ISO SQL/92 standard requires that an error "SQLSTATE = 22003 - overflow error" should be generated. The new default behavior corresponds to this behavior. To obtain the same behavior as previous versions, set the database compatibility option ANSI_INTEGER_OVERFLOW to OFF. The LOAD TABLE and UNLOAD TABLE statements now require table ownership or DBA authority. Previously, only INSERT/DELETE permission was required. As LOAD TABLE adds data without a transaction log record or firing triggers, the LOAD TABLE statement provided a loophole past enforcement of business rules. LOAD TABLE and UNLOAD TABLE no longer carry out an automatic commit. 11.2 New features ----------------- This section lists new features in Release 5.5, with pointers to the online Help index for more information. To locate a topic in the online Help, goto the index or search facility and type the topic name. Compatibility enhancements Database options for Transact-SQL and ISO SQL/92 compatibility Several database options have been added to allow improved compatibility with Sybase SQL Server and with ISO SQL/92, while maintaining the ability to be compatibile with existing applications. For information on these options, see "SET OPTION statement" in the online Help index. The CONVERT function now converts strings to dates and times, as well as the converse. Live backup A new option for the backup utility allows a continuous backup of the transaction log. In case of a server shutdown, this log file can be used for a rapid restart of the system. Embedded SQL enhancements CONNECT USING statement can be used from Embedded SQL. For information, see "CONNECT statement" in the online Help index. The PREPARE statement has been enhanced to allow immediate describing and/or execution of the prepared syntax. For information, see PREPARE statement" in the online Help index. A new set of statements is available for descriptor handling. For information, see "ALLOCATE DESCRIPTOR statement", "DEALLOCATE DESCRIPTOR statement", "GET DESCRIPTOR statement", and "SET DESCRIPTOR statement", in the online Help index. Dynamic loading of Embedded SQL interfacy library DLLs is made possible without linking against the imports libraries. For more information on this technique, see "Interface library DLL dynamic loading" in the online Help index. SQL Remote enhancements The new REPLICATION_ERROR database option allows improved tracking and reporting of replication errors. For information, see "Error reporting and conflict resolution in SQL Remote", in the online Help index. A command line argument for DBREMOTE allows memory usage to be controlled for environments running with many remote databases (over a thousand). New features assist in the replication of "blobs": long data types. For information, see "Replication of blobs", in the online Help index. SQL Central enhancements A Table Editor window is provided to enable Table creation and editing in a single window. Database options can now be set from SQL Central. Right-click on a database and select Options from the pop-up menu. You can unload specific tables from SQL Central, and validate a database to which you are not connected. A wizard is provided for creating user-defined functions. Open Server Gateway enhancements The Open Server Gateway automatically sets database options to help ensure maximal compatibility between SQL Anywhere and SQL Server behavior. 11.3 NetImpact Dynamo ---------------------- Printed Documentation corrections The following features are not documented in the printed documentation: * Web sites can include linked folders, which link to documents stored as files, in addition to documents stored in a database. Linked folders cannot contain dynamic content. For more information, see "Working with folders and documents" in the online Help index. * Several of the built-in script objects have additional methods and properties. For information, see "Predefined objects" in the online Help. The following are known inaccuracies in the printed documentation: Page 63-64 The list of required files for deployment has been modified. For an updated list, see "Required files for the Application Servers" in the online Help index. Page 64-65 The ISAPI filter DLL described on this page is not supported in the current release. Page 65 The instructions for Web server configuration have been updated and instructions for NSAPI Web server configuration added. For updated instructions, see the section Step 2: configure the Web server Page 118 The argument to the ExportTo method of the document object is a directory, not a file name. Sessions Dynamo applications may use the session object for managing persistent information. Microsoft's Internet Explorer 2.0 does not support the session object and thus applications using it will not work with IE 2.0. The Dynamo demo application uses the session object. Also, the default timeout on the session object (the idle time before the object will be released) is 5 minutes. Thus, applications such as the Dynamo demo application, will not work properly if left idle for more than 5 minutes. This can be modified by setting the registry entry in the Local Machine key: Software\Sybase\NetImpact\Dynamo\Cookie Timeout The setting should be string type and is the number of minutes for the timeout. 12. About Release 5.5.01 ------------------------ 12.1 New features ----------------- This section lists new features in Release 5.5.01, with pointers to the online Help index for more information. To locate a topic in the online Help index, go to the index or search facility and type the topic name. SQL enhancements A new special constant, LAST USER, has been added as a way of identifying which user last changed a row. For information, see "Constants in Expressions" in the online Help index. New database options A new database option, FIRE_TRIGGERS, allows trigger firing to be turned off. This is relevant for SQL Server to SQL Anywhere replication. For information, see "Compatibility options" in the online Help index. A new database option, BACKGROUND_PRIORITY, allows tasks to run with minimal impact on other connections. For information, see "Database options" in the online Help index. SQL Remote enhancements A Message Agent for NetWare is now available. This is named DBREMOTE.NLM. For information, see "Adding SQL Remote message types" in the online Help index. Server and engine switches The SESSIONS network communications option (-x switch) on the can be used to change the maximum number of NetBIOS connections allowed to a given server. For information, see "Network communications parameters", in the online Help index. SQL Central enhancements The script editor and script editor console now support printing. For information, see the SQL Central online Help. 13. About Release 5.5.02 ------------------------ This section includes the following information: 13.1. SQL Central name change 13.2. New features 13.3. Behavior changes 13.4 NetImpact Dynamo new features 13.1. SQL Central name change ----------------------------- With this release, the name of the SQL Central management utility has changed to Sybase Central. The utility is now used to manage applications such as NetImpact Dynamo which, although employing relational databases, are not themselves relational databases. The name Sybase Central reflects this broader range of applications managed by the utility. 13.2. New features ------------------ This section lists new features in Release 5.5.02, with pointers to the online Help index for more information. To locate a topic in the online Help index, go to the index or search facility and type the topic name. Sybase Central enhancements The features of the Service Manager have been incorporated into Sybase Central, and enhanced. The Service Manager is still included for compatibility, but Sybase Central has more functionality and its use is recommended. For information, see "Running Programs as Services", in the online Help index and the Sybase Central online Help. A rebuild wizard has been added, to assist with unloading and reloading databases. For information, see the Sybase Central online Help. SQL Remote enhancements Several options have been added to the Message Agent (DBREMOTE). o The -u switch sends only backed up transactions. For information, see "The SQL Remote Message Agent" in the online Help index o The -x switch renames the transaction log. For information, see "Backup procedures at remote databases" in the online Help index. The UPDATE PUBLICATION statement now allows the old subscribe by list as well as the new subscribe by list. Using this feature can make SQL Remote triggers more efficient. For information, see "UPDATE statement syntax" in the online Help index. The SMTP message link has a new control parameter indicating the local host name. For information, see "SMTP message control parameters" in the online Help index. SQL enhancements New properties have been added to the list of properties accessible by SQL Anywhere system functions. For information, see "System functions" in the online Help index. xp_msver is a system stored procedure that returns version and other information about the SQL Anywhere softwrare. For information, see "xp_msver system function" in the online Help index. Search conditions using the IN clause have been expanded. For information, see "IN conditions" in the online Help index. Utility enhancements DBTRAN displays the starting offset of the transaction log being translated. This is implemented primarily for replication installations. For information, see "DBTRAN command line" in the online Help index. Connection parameter enhancements The PORT connection parameter, used with the -x option of the client and server, has been changed to ServerPort. The DoBroadcast and Host connection parameters have been added for operating systems other than Windows NT and Windows 95, for non-Windows clients to talk more easily with Windows 95 and NT servers. 13.3. Behavior changes ---------------------- Permissions for the VALIDATE TABLE statement (used by dbvalid) now requires the user ot be the table owner or a user with either DBA or REMOTE DBA authority. Previously, VALIDATE TABLE was permitted by a user with SELECT permissions on the table and resource authority (permission to create tables). Passthrough mode behavior for CALL statements has changed. For information, see "Stored procedures and control statements in passthrough mode" in the online Help index. 13.4 NetImpact Dynamo New Features ---------------------------------- DynaScript The DynaScript SCRIPT language has been updated with several new functions and objects to make working with Web sites and databases easier. Predefined object The predefined objects File and session, have been added to Dynamo for working with Web sites and database content. Upgrading previously existing sites If reinstalling NetImpact Dynamo over a preexisting version, previously existing sites sometimes need to be upgraded to work with the new version. This may be done automatically the first time the Web site is connected to after a new version has been installed, see "Installation upgrade of Web sites" in the online Help index. Deployment to Win32s A Web site may now be deployed to a Win32s system if first set up on a Windows 95 or Windows NT system. For information, see "Setting up Win32s for remote users" in the online Help index. The Personal Web Server for Win32s requires Win32s version 1.30 or later. Configuring Web servers The chapter "Configuring Web Servers and Web Sites" has been rewritten to provide step by step instructions for users that need to configure an ISAPI, NSAPI or CGI web server to run with NetImpact Dynamo. The first three steps of configuring a Web server for NetImpact Dynamo may now be done through the SQL Anywhere installation program. Once SQL Anywhere has been installed, the installation program searches your machine for installed web servers. For each server it detects it will you if you would like to have the server configured at this time to work with NetImpact Dynamo. For more information see "Configuring web servers during installation" in the online Help index. Running the SQL Anywhere Database server for NetImpact Dynamo A new chapter has been added to the NetImpact Dynamo documentation about running the SQL Anywhere server as a service with NetImpact Dynamo. Information about why you would want to do this as well as a step by step explanation is provided, see "Setting up the SQL Anywhere Database Server" in the online Help content. Language Support NetImpact Dynamo supports multi-byte character sets. For information, see "Language Support" in the online help index. 14. Notes on replicated Web sites --------------------------------- Dynamo 1.2 creates and uses a database table, called WebVersion, that was not present in previous releases. The presence of this table indicates that the Web site has been upgraded to version 1.2. This new table needs to be part of the replicated environment - it is not replicated automatically. The following example script propagates the upgrade of the WebVersion table to a subscription named website_publication. website_publication should be replaced with your own subscription name and then the script should be run against the consolidated database. 1) Create a file, c:\upd_dynamo.sql, containing the following text. PASSTHROUGH ONLY FOR SUBSCRIPTION TO website_publication; CREATE TABLE WebVersion (NIDVersion integer); INSERT INTO WebVersion VALUES (2); PASSTHROUGH STOP; PASSTHROUGH FOR SUBSCRIPTION TO website_publication; ALTER PUBLICATION website_publication ADD TABLE WebVersion; PASSTHROUGH STOP; 2) Type the following command: isql -c dba,sql,consolid.db where the dba is the database administrator of the consolidated database and consolid.db is the consolidated database. If you are in Windows 3.x, run isqlw -c dba,sql,consolid.db 3) Enter the following command: read c:\upd_dynamo.sql; where c:\upd_dynamo.sql is the fully qualified file that you created in step 1. 4) Press the 'Execute' button. The next time you run SQL Remote your Web site information will be replicated.
