after installtion and configuration from IDS 11.70 (free version) on Fedora 17 (kernel 3.6.2-4.fc17.i686) I get following failure message: 'OS couldn't allocate first resident segment at SHMBASE (0x8947451)'. I also did change SHMBASE-variable to 0xb7600000 but doesn't help to solve the problem. I also read some articles (about managig from shared memory under REDHAT linux) from IBM-s support site but this don't help me.
Does anyone have a idea how to solve this problem.
File attached: output form 'oninit -vy' and 'onstat -m'
Thanks in advance

Re: OS couldn't allocate first resident segment at SHMBASE...2012-12-10T11:04:16Z in response to SystemAdminHello,
first of all: is this 32bit or 64bit IDS and OS? Please let us know 'oninit -V' output.
Then I'd retry this starting with a really small shared memory configuration: small BUFFERPOOL + LOCKS (making up first "resident" segment essentially) and small SHMVIRTSIZE.
Once this succeeds, try again with increased sizes.
You might be running into some pre-loaded library collisions.
To find out about this, you can start oninit under debugger (gdb) control, let it run until first (or second/third) shmget(), and then look at the processes memory map (in gdb: 'info shared', or 'cat /proc/<oninit_PID>/maps'.

I'll give you feedback if it does work after changes on shared memeory.
Re: OS couldn't allocate first resident segment at SHMBASE...2013-02-01T21:22:52Z in response to andreaslHi Andreas,
it seems to be no way to get it on running. What ever I do, I get the message : "Fatal error in shared memoryi initialization". Do you have any other idea how to fix it!?
Thx in advance
