Hello Experts,
Our target is to increase Extended memory(em/global_area_MB) this is because we are going to extended the rdisp/plugin_auto_logout from 30 min to 60 min. Also we are going to increase the ICM TIMEOUT parameters from 900sec (15 min) to approx 1800 sec (30 min) so this may increase the concurrent users into the system.
Just to brief :
The current scenario for 650-700 concurrent users are logged in at a same time via Web platform with auto logout timer of 1,800 sec. = 30 min.
Regarding Memory Consumption, the ITS server memory is occupying 3GB of total 8GB.
The ITS uses memory of the extended global memory area (EG) which is configured to 8GB via the parameter em/global_area_MB.
Even to protect the WebAS from running out of memory there is a threshold set so if the amount of memory used reaches watermark, further ITS sessions will be refused. The parameter itsp/max_eg_mem_percent (Set to 80%) determines this limit, default value 80. This means that no more ITS logons are possible as long as the amount of free memory is less than 20%.
We have checked the profile parameter icm/max_conn(Maximum number of open connections at one time) value is 1000. This means 1000 users can logged in at a same time.
We need to increase the system memory a little more to avoid any performance issues.
Kindly suggest.
Thanks.
