Here is the scenario: We are running RedHat 6.1 (build 2.2.5-15) w/IDS 7.30.UC7. We have installed [it] successfully twice, however, after the initial config of the sqlhosts and onconfig files and during the execution of the "oninit -i", we get the following error: "oninit: Fatal error in shared memory creation" Could someone point me in the right direction on fixing this? Is it a Linux or Informix problem? Thank you. * Sent from RemarQ http://www.remarq.com The Internet's Discussion Network * The fastest and easiest way to search and participate in Usenet - Free!

Try reducing SHMVIRTSIZE and try it again. I feel some of the resources you have allocated are bit high. Also further analysis, it will be good if you post your ONCONFIG to the group.

I am posting my online.log, onconfig, and sqlhosts files. Hopefully this will help in determining what's wrong. Thanks again in advance!

Didn't see the above tread, but anyway:) Start informix with -v too se where shit happens: "oninit -v" Use ipcs to see shared memory segments: "ipcs -m" Use ipcrm to remove shared memory segments: "man ipcrm" Thomas

Thanks again in advance! > > "ONLINE.LOG" > ------------------------------------------------------------------------ > 17:51:48 shmget: [EEXIST][17]: key 52574801: shared memory already> exists The number in brackets is the errno value returned by shmget. On most UNIXes errno 17 is "File exists", which in errno.h is EEXIST. If you check the man page for shmget you will see that it returns EEXIST when the shared memory segment already exists in memory. This is probably due to an earlier attempt to bring the engine up with parameters which were too large or some such. Use ipcs to list shared memory segments and semaphores and delete any owned by group informix using ipcrm. Then try oninit again with the -v flag included to get a better idea of where it is if it crashes again. Art S.
