OC SS7 application problem

[Alan Phillips_2]

I am trying to get a simple application to run using the OC SS7 TCAP api. The problem is that messages (from an MGTS) are not getting to the application. When I use the SCCP API, the messages do get there. Also, I tried running the sample TCAP app from the tutorial and got the same result.

My suspicion is that something is either not configured right or is not in the right state, although I cannot find any indication of such a problem using the SS7 Monitor and there are no console messages coming out.

Any ideas about what I've got wrong would be
appreciated.

Thank you,
Alan Phillips

This is a real shot in the dark.

If the application uses shared memory, your kernel allocation of such memory might not be adequate.

ipcs

to see whats in use.

Check the kernel parameters shmmax, shmseg.

Thanks for your reply, Steven. The app I'm currently using is just a small test app - it doesn't do anything explicitly with shared memory. And the system I'm on is basically empty at this time.

The shmmax value is 67108864 and the shmseg value is 120. I didn't see anything in the ipcs output, but I'm not really a Unix expert, either.

Thanks,
Alan
