Oracle Process

Question

Dear Gurus
We are working in Online Application, and certain peak time our database activity increases and more than 1100 users login. ( checked in view v$session and v$parameter )
Process parameter value = 1100
sessions paramter value = 1215
OS : Windows 2003 server
Oracle : 10.2.0
RAM : 20 GB
SGA_TARGET : 7GB
Server : Intel Xeon (R) 8 cpu
Issues : DB server usage went 100% for few seconds, and then back to around 50%. Some users get DB server errors, because the process parameter is limited to 1100.
Can you guide me ? should I increase the process parameter to 2000 ??
or should I replace the existing server with heavy server and then increase the process parameter to 2000.
Kind Regards.

Kind Regards.HI,
You can check v$resource_limit
select * from v$resource_limit where resource_name in ('processes','sessions');
RESOURCE_NAME   CURRENT_UTILIZATION MAX_UTILIZATION INITIAL_AL     LIMIT_VALU     
processes     32               150            150            150
sessions     37               155            170            170If MAX_UTILIZATION is equal to Initial value of parameter and you are getting error regarding the same.
You can think of increasing the values of the parameters
