Home -> Community -> Mailing Lists -> Oracle-L -> RE: 9205/9206 RAC on Linux RHAS 3.0
I found out recently;
Oracle 9i support ASYNC IO on Linux.
Oracle OCFS supports ASYNC IO on Linux.
*HOWEVER* Oracle 9i RAC + OCFS + using ASYNC IO is NOT supported. ...but I am currently running it and I immediately notice that "shutdown immediate" hangs / terminates.
Have to "Ctrl+c" in me SQL> term and issue "shutdown immediate" again to stop the database!
Saw a simple bug logged on Metalink for HP and RAC...no good info though.

Subject: RE: 9205/9206 RAC on Linux RHAS 3.0
Maybe this is not relevant but I'm running several 9.2.0.5/6 on linux and a few RACs; the difference is that I'm using SLES not RHAS.
The configuration is not "bugless" (especially RAC) but I don't believe there is a product out there totally bugfree. Yesterday I experienced a crash on RAC 9.2.0.5 due to the number of pthread for process. Patching at 9.2.0.6 should solve the problem but I'm living with crashes since 9.2.0.1 and I'm confident the new patchset will introduce new issues.
Actually I don't see RAC has the definitive HA solution. I have higher uptime on single instance systems (to defend RAC I have to admit the one which crashes is the most stressed system of mine).
AIO is more problematic on SLES(9) than redhat.
Nonetheless linux is my preferred platform for oracle so far.
