Message: Hi Guys

I have the database server that keeps on giving me issues. Every time we have about 700 processes we can't fork new processes.

How do I see what is the maximum processes that can run simultaneously on the server?

Please help!!!!

Thanks in advance...

Message: Hello Tso,

if I understand, your issue is at OS level, about the resources allocated to the user running the database (presumably "oracle"). In this case you have to talk with your system administrator.

If your issue is at database level, changing the value of init parameters can be the thing to do. To have an idea of the current usage and maximum usage seen since startup for some resources, you can run the following:
SET PAGES 32000 LINES 130

COL limit FOR A12
COL pctmax FOR 990.0
SELECT resource_name, current_utilization current_used, max_utilization max_used, limit_value limit
, CASE WHEN TRIM( limit_value ) = 'UNLIMITED' THEN 0
WHEN TRIM( limit_value ) = '0' THEN 0
ELSE max_utilization * 100 / TO_NUMBER( limit_value )
END pctmax
FROM v$resource_limit
ORDER BY 1;
Best regards,

Bruno Vroman.
