This directory contains the fix for APAR IY89080. Error Description ----------------- ORA-600 errors in the Oracle Alert logs Oracle is not initializing some AIOCB fields correctly on version 9. This is causing some AIOCBs to look like they are requesting IOCP function. The IOCP functions are not loaded so the AIOCB is being errored off with EPERM and this is bubble back to the listio() call which in turn makes Oracle believe there are no IOs in flight when there are. This fix will efectively turn off IOCP support with AIO until we can correctly return an EIO or some error to the listio call correctly. Prerequisites ------------- This fix applies to the 5300-05 Technology Level only and requires that the bos.rte.aio fileset is at the 5.3.0.50 level. Installation ------------ Download iy89080.epkg.Z in binary format and then use the following command to install the fix. emgr -e iy89080.epkg.Z
