RE: Shared memmory initialization

It is possible that you have 2 problems: 1) An I/O error on your root chunk. 2) Your Informix instance may have crashed previously and did not remove the shared memory segments. To identify these shared memory segments, issue the following command: ipcs -m | grep informix Informix shared memory segments will have owner=root, group=informix. The key to these memory segments will start with 0x5256 if your Informix SERVERNUM in the $ONCONFIG file is 0. If non-zero, add its value to this value. I.E. 0x5257 for server number = 1 Use the ipcrm to remove these segments before starting Informix.
