public final class UnavailableInterBaseServerException

extends interbase.interclient.SQLException

InterServer is unable to locate the InterBase application or service.

If you are running InterBase as an application and not a service, then InterServer must also be running as an application and not a service.

From the InterServer configuration utility in the InterClient program group, first stop the InterServer service then change the server startup mode from "Service" to "Application". Finally start the InterServer application from the InterServer icon in the InterClient program group.

Make sure the InterBase Service is running and is using the correct version of gds32.dll. The gds32.dll in your system32 directory must be from the installed version of InterBase, and not a previously installed version.

The Delphi 1.0 version of InterBase will not work.

Local InterBase 4.1 will not run as a service on NT (this is ok, but you will have to run InterServer as an application). So, with Local InterBase 4.1, start the server by clicking on the icon in your program group. Once you see the icon, use one of the InterBase tools to try and connect to it (ServerManager might be the easiest one).

If you can not connect to InterBase at this point, then make sure:

• You have GDS32.DLL in your Windows System directory.
• You have the following in your services file: gdb_tcp 3050/tcp
• Your registry keys are correct (to be sure of this, use the instreg or regcfg utilities to set them to your InterBase root directory).

Note:

• GDS32.DLL is the 32-bit client which comes with Delphi 2.x and 3.0. It is installed when you choose to install Local InterBase.
• WS-V4.0xx is the 16-bit local access server which will not work with InterClient since it can not load GDS32.DLL.

The error code associated with this exception is isc_unavailable from the InterBase ibase.h file.
