shared memory problem

Posted in 2000

Summary

David Palmer got shmat EINVAL, base address illegal and out of virtual shared memory on Informix 7.3 (also called 7.2). Alnis Bajars asked for ONCONFIG, kernel parameters and onstat -g seg. David Williams advised adding SHMBASE to ONCONFIG and raising SHMVIRTSIZE so only one V segment shows. June Tong said SHMMAX is usually too low. Palmer posted onstat -g seg output; no outcome was reported.

On 7.2.0, I'm getting a message in the log that is as follows: 14:34:11 shmat: [EINVAL][22]: shared memory base address illegal 14:34:11 using 0xd0000000, needs 0xffffffff 14:34:11 out of virtual shared memory Could someone explain this for me and suggest a remedy?

Hi David. Plz. supply your $ONCONFIG file. Reviewing your kernel parameters would be good. If your server is still running, output from onstat -g seg may be helpful.

Check in the files $INFORMIXDIR/release/0333/en_us/IDS* $INFORMIXDIR/release/0333/en_us/ONLINE* You probably need to add an entry for SHMBASE into the ONCONFIG file. Also increase SHMVIRTSIZE so that onstat -g seg only shows 1 segment of type 'V'. -- David Williams

Usually due to the kernel parameter SHMMAX not being high enough. See my Unofficial FAQ: http://www.geocities.com/SiliconValley/Bridge/4578/faq.html June -- june_t@hotmail.com Living on Snickers bars in San Mateo Please do not send Informix questions to this account. I would add 'Please do not send spam to this account' but I suppose I would be wasting my bits.
