 Re: Help: 10g on Fedora Core 2, ORA-27125 Not sure if you\'ve done this yet or not but try running the following from the command line before you start oracle: echo 4294967295 > /proc/sys/kernel/shmmax This *should* fix the error. Although I have yet to do an install on FC2, this worked for me to fix the same error on RH AS3.1 -- David      |

That would be kernel.shmmax. Be a good idea to look at the settings for kernel.sem, too and see if they need changing. sysctl -a will give you listing of all kernel settings and you can grep out the ones you're interested in. I'm not familiar with FC2, but since it's from the same tree as RHEL3, I'm assuming it has this utility and .conf file. Corrections welcomed. Cheers, TD |

I don't see the reason why it schould change it, but anyway, it's relatively simple to correct... Igor |
