The pre installation checklist in the Install Guide talks only about minimum requirements for one sp_cop. Will the kernel requirements be different if there are many sp_cops each of them having multiple queues
No, the recommended setting in pre installation checklist in the Install Guide is sufficient regardless of how many sp_cops are running on an AIX machine. This is because unlike the other UNIX variants, AIX doesn't use the kernel parameters for shared memory and semaphores. The issues for AIX are EXTSHM=ON and the per-process limit that is relative to other process usage and limits. Signs that the per-process limit have been reached are:
1) license errors
2) "Unknown problem" (this is also a license error)
3) sp_cop spins endlessly
