Gurus,

We have recently moved from Solaris to Linux for our 12.1.2 E-business suite environment, RDBMS(11.1.0.7.6), GRID/ASM(11.2.0.2) and are observing following warnings in rdbms trace files:

Noticed that the module information in the trace files varies from job queue process,parallel query slave and httpd sessions.

Did search for this error in MOS and got few hits but did not have an exact match of our situation, raised SR with oracle support.

Have any of you guys encountered these warnings and know what OS parameter to change to fix this and any recommendation or criteria for setting value for maxaio.

disk_asynch_io has been set to TRUE.

Regards,
Sanjeev.
