Hi,

AIX 5.1 Oracle 9.2.0.4

I have the following parameters:
minservers 40
maxservers 200
maxreqs 4096

I have often the following :
Warning: lio_listio returned EAGAIN
Performance degradation may be seen.

According the documentation, i have to increase maxservers Is there any issue to set 300 for maxservers and maxreqs 8192 ?

I plan to set , according the documentation, vmtune -c 8
vmtune -r 32 -R 64 ( MINPGAHEAD, MAXPGAHEAD )

Have you any experiences about these parameters ?

Thanks in advance ... Received on Thu Jul 20 2006 - 13:58:06 CDT
