What is maxreqs parameter in AIX?
Hello gentlemen,
I am running Aix 5.3 and Oracle 9.1;
What is the parameter "maxreqs" in Aix?
# lsattr -E -l aio0 -a maxreqs
maxreqs 4096 Maximum number of REQUESTS True;
Last night our database was down. Someone was telling it was due to maxreqs was full.
Question to gentlmen what is the maxreqs used for?
And is there any way to monitor whether the AIO maxreqs is going to full. And what step I can take to avoid this?
Cheers,
Purple
