Hi, there.
My customer has problem related to shared memory.
He cannot remove the shared memories which were allocated and released by
informix.
Well the processes related to shm # 513 and shm # 514 is no longer alive.
And KEY of zero means that he run ipcrm.
I don't know why system would not release shared memory in situation that
ipcrm was run and all related processes was killed.
Is there any mothod to release these shared memories in this case ?
Digital UNIX V3.2G is used.
Please help !!!
# ipcs -am

You know,
In this situation, I cannot
# sysconfig -q ipc

shm-min = 1
shm-mni = 256
shm-seg = 150

The normal way to stop online is onmode -k In your particular case, probably you still have an old oninit process daemon running do ps -ef|grep oninit and kill the old one with PPID 1, this will remove the shm segments Francoise | |||||
| 9631.2 | onmode -k ? | DEKVC::JEONGEUNKIM | Wed Apr 30 1997 05:52 | 12 | |

$INFORMIXDIR/bin contains executables: oninit, onmode ... You should NEVER kill online but stop it properly | |||||
