ORA-27125: unable to create shared memory segment
This post is for the users who got this error message (ORA-27125: unable to create shared memory segment) when they try to run Oracle 10g on linux.
Are 2 solutions for this problem:
1. Disable Huge TLB tables
in shell and after just restart oracle. (Take care because you will need a lot of RAM if you disable HUGETLBFS)
2. You need to recompile your linux kernel with following options enabled
I hope this post will be helpful.
