$ ipcs -ma | grep oracle
m      80902 0x1550f7c4 --rw-r-----    oracle  oinstall    oracle  oinstall     16 1593843712  8366 10800 19:22:00 19:22:00 17:09:20

My requrement was

1 .Can Assign assign 500MB  more memory to ORACLE -How to add ?

2.Is there any impact, if we raise the oracle memory from 1.5GB to 2GB

Thanks in Advance

What is your value for shmmax(5)?

>m      80902 0x1550f7c4 --rw-r-----    oracle   16 1593843712

So it is using 1.5 GB now.
