Environment: Oracle 18.104.22.168 on Solaris 8
Is it a bad idea to shrink SHARED_POOL_SIZE from 300MB to 200M using
ALTER SYSTEM SET SHARED_POOL_SIZE=200M SCOPE=BOTH?
It's been taking 15 mins since I issued the command and I am still waiting for the return prompt.
I notice the checkpoint process has been pretty busy with consistent 50% CPU usage. Does it essentially flush the shared pool and allocate it?
BTW, I do this because I have to increase JAVA_POOL_SIZE significantly (thus reduce SHARED_POOL_SIZE temporarily) in order to accomodate the 22.214.171.124 patch's requirement for JAVA_POOL_SIZE > 150M.
