shmget: [EEXIST][17]: key 52584801: shared memory already exists

Hi! Guys please help!!! I've tried everything with this shared memory segment(rebooted), but nothing helped. still doesn't want to do oninit -iv here is some tips... online.log Tue Nov 30 15:20:02 2004 15:20:02 Event alarms enabled.

If there are no other IDS instances up then you probably should not see anything owned by informix (well I don't on our machines.) If there are entries, and they have a KEY of 0x52564801, then you could remove them with "ipcrm". 2) Are you sure there are no other instances running with SERVERNUM of 2. If you are doing an "oninit -iy", did you perhaps nick the onconfig from another instance as a template? ;-) Hope this helps, Donny
