Hi I am using sybase 12.5.0.3 on HP-UX 11i with RP 2470 2 processor box.
Everything seems to fine but async i/o option is giving me the problem..

The error message when i start sybase is as follows
"ioctl(ASYNC_CONFIG) failed: Resource temporarily unavailable"
and its going to statndard unix i/o..

I tried giving setprivgrp RTPRIO MLOCK CHOWN

still the same error..
I have 1 GB memory and shared memory i set as
"960495616"

Thanks in Advance

Hi Steve
Thanks again for the reply.
I solved the problem..

It turned out to be memory allocation problem..

I allocated more data cache in sybase, as sybase only can access 75% of the physical memory, the data cache was exceeding the 75%. So i reduced the data cache in sybase.
Now async i/o is working fine..

Thanks & Regards
