commands are killed immediately.

[desbo]

I am in the process right now of changing over from a p630 to a 560Q. Everything has gone OK but when I sign on as one of the users and execute a command it is killed immediately.
We are running AIX 5.2 ML 8.
I have found something on the web about problems when ulimit is set to unlimited. It is set to unlimited but so was our old p630.

Can anyone help me with this quickly as it is nearly 20:00 and i am keen to get it finished and home.

Thanks

To determine how many LEGACY AIO Servers are currently running, type the following information on the command line:
pstat -a | egrep ' aioserver' | wc -l

I still really need to know ....

how much memory/processing power does increasing these values take? We have some processor capacity but practically no memory capacity free.
Thanks

AIO memory consumption is not zero but it is not big either, AIO is just a question of swapping about (to an d fro between application and aioservers) of pointers to modified IO pages (Async write) or free pages which need to be filled (Async read). The pages themselves already exist in memory.

I'd go double from what you have already, it just means extra process table slots (which are also already there) being used (the aioserver processes themselves are also relatively small) and some extra memory being used for the AIO request pointers, then see if your application/DB performs better.
