You’d need to look for a segment with no attached processes (NATTACH=0). It’s a dead segment that can be removed with ipcrm.

Hi Mark not sure what to look for with that. There is 22 other databases running on this server. Its a dev server with a bunch of clones and little use.

Ok I am confused. I am trying to make a thin clone of our database from one server to another. Something I have done many times. I use NetApp Snap Manager for Oracle. Oracle EE 12.2.0.1 running on Oracle Linux 7. The clone process is failing with ORA-27100: shared memory realm already exists.
This database does not currently exist. I ran a ps -ef | grep for my database name and no process are found. There is nothing in /etc/oratab. I've tried adding an entry to make sure a database with that name is not running. There is no pfile, spfile, password file. I've checked /dev/shm for any files related to my database name and there is nothing. I don't understand by it thinks shared memory realm already exists.
Any suggestions?
Thanks,
