Hello Murali ,

There are isues like in sam , we will get something like :
exec(2): could not load a.out , untill we revert stack size to some 8192 values etc.
some services of critical application will die out and we will have restart it and things like that.

What are the previous and current values of maxssiz?

Post:

kcusage|grep -e maxssiz -e maxssiz_64bit

[DeafFrog]

hello Dennis and Anshumali ,

Please find the current usage :
kcusage|grep -e maxssiz -e maxssiz_64bit
maxssiz 540672 / 134217728
maxssiz_64bit 786432 / 268435456

>Please find the current usage

I don't see anything wrong. What were the exact errors you were getting?
Note: If you increase maxssiz too large, you won't be able to run applications.

Hello Dennis ,

I have users complained that application are performing badly , i see the number of opened cursor (In DB ) , the threshold reached every time and applications will have problems , so the performance problem has been rounded to "number of opened cursor" in DB.

I will close this thread and open a new in section databases of this forum.

Many Thanks for the inputs.

Regards ,
