- I am running a configuration with 4 MX-SINIX5.24/NSC.
- On one machine a dabtabase is runnging (ORACLE).
- The userinterface are SQLFORMS30-Masks which access via
- SQLNET to the database.
- On my backend - machine I am running out of memory therefore
- the machine starts paging/swapping a lot.
- Yesterday I had the problem that the machine had a
- system load of 90% ( 8 CPU ).
- After analyzing the system with TRACEX(a kernel trace-utility)
- I found out that all the ORACLE-Backend processes approx. 80
- made many of the following system-calls.
- The interval for the listed number is 159 sec.
-
- sigvec approx. 5000-6000
- sigsetmask approx. 1600-1800
- sigblock approx. 700
- sigpause approx. 600
-
- As I have no idea in understainding this values in terms of figuring out
- if these are vlues that showing a synchronizationb problem ( TCP/IP,
- acessing ALM-shared memory ...) I would need the
- help of a wizard.
- THANKS
