Applies to:Oracle Database - Enterprise Edition - Version 184.108.40.206 to 220.127.116.11 [Release 12.1]
Information in this document applies to any platform.
Started seeing the below error messages in the parallel slave processes in batch processing after migrating to 12.1. This was never a problem in earlier versions and used to work fine.
You would also observe the value of "fs.aio-nr" is no where close to the max value of "fs.aio-max-nr" during issue period. The value of "fs.aio-max-nr" is also set to sufficiently high value and more than minimal recommended value of 3145728.
Upgrade to 18.104.22.168/22.214.171.124 or new 126.96.36.199/188.8.131.52 installation
