Fatal Error in Shared Memory Creation

Hi everyone, I am new to informix. Really learning lot of things from this newsgroup. For couple of early question I recieved good solutions. Thankyou. This time I am facing a problem in Informix On-line startup with Fatal error in Shared Memory Creation. After installing Informix 7.24, I was trying to setup Informix from Off-line to On-line mode through 'onmonitor' > onmonitor > selected 'mode' > then selected 'startup' I got the following error: initializing, please wait ... oninit: Fatal error in shared memory creation press return to continue.... I am not able to set to 'On-line', I am afraid anywhere missing out in setting the configuration. Can any of you help me, to how I can resolve this problem. Thanks n regards, Harish

Have you verified that the kernel parameters are set correctly?

Hi Harish, most of the time there will be some message in your online.log (find path and filename in ONCONFIG). Try oninit from the command-line; it's possible that you'll find messages at your console as well. You could also try oninit -v (verbose). You could check, if you find Shared Memory Segments using ipcs. Hope this helps, Peter hpandu wrote: > > Hi everyone, > > I am new to informix. > Really learning lot of things from this newsgroup.

There could be many reasons that causes OnLine doing such a thing. First of all check if your kernel params are set, as described in release notes. Then you must initialize OnLine. Do it with "oninit - iy" command. This is relatively long process, dependent on your configuration. During this process monitor OnLine state through the log. You must see something like "Sysmaster database built succesfully". After this completes, your system is OnLine. But remember, that this initialisation step performed only once - as you initally install and setup OnLine. This operation is destructive to your OnLine data. If you already initialise your server, and check kernel params, and anyway got the same message, then it's time to look into your ONCONFIG. Check, shared memory params there. Pay attention, that size of your shared memory is not more, than amount of physical memory installed + swap. For more advices send us your online.log and ONCONFIG. -- With best regards, Yuri Dovgart, SAP R/3, Informix consultant, "Telecominvest" company.
