Hello everyone.
I would like to ask for advice on the problem of restarting after stopping Informix.
Below is the order in which the instances were created.
1. Compress the entire Informix directory $INFORMIXDIR of the existing host (host1) with tar
2. Copy the tar file to another host (host_dev)
3. Uncompress tar file and start instance (-ivy)
The start of the newly configured instance on host_dev worked well, but when I restarted again after shutting down with onmode -ky command, shmget: [EEXIST][17] error message occurred. Checking with the ipcs command, the shared memory segment was not removed. It was removed with the onclean command.
Interestingly, running the onmode -ky command as the root user removed the shared memory segment.
It is being used in an AIX environment and the informix user ID (uid) and group ID (gid) are the same.
The authority of the /INFORMIXTMP directory is informix:informix. There are no other instances with the same SERVERNUM.
What else should I check?
