AIX 5.3 Oracle 9i startup error ORA-27061

The old system has been operating normally and suddenly the database cannot be accessed, as shown below:

Aix5.3 system with Oracle9i installed

Log on to the aix system and find that the listener has been interrupted. Prepare to restart the database.

(1) oracle $ lsnrctl start

The listener starts normally.

(2)

An error is reported after mounted is successful:

Analysis:

The error message indicates that the system IO is asynchronous.

Cause not found. Restart aix

Shutdown-Fr

Start the database, still: ORA-27061: skgfospo: waiting for async I/OS failed

The specific cause should be aix5.3 system problems. You need to install the IBM Patch: Fix APAR IZ03260.

There is a temporary solution: Increase the maxreqs Parameter

Switch to root

# Chdev-l aio0-P-a maxreqs = 16384

Restart the database.

However, after the aix system is restarted, the database still cannot be started. It is completely solved by installing the aix system patch.
