Target audience for this Alert: all SAP installations with DBMS Oracle, operating system AIX and one of the following AIX levels:
(use the command oslevel -s to see the exact version level)
These AIX service packs contain a bug that has led to several cases of database corruption. Both Oracle 11 and 12 are affected; the installed SAP Bundle Patch (SBP) has no relevance for this issue. The corruption can damage both data files and redo logs; it manifests itself as ORA-00600 and ORA-07445 errors. Core dumps of Oracle processes may also occur.
The problem is solved in the next higher AIX level (126.96.36.199 / 188.8.131.52 / 184.108.40.206 / 220.127.116.11 / 18.104.22.168), but IBM also makes available an interim fix (iFix) for the five versions affected.
Instructions for fixing this potentially serious issue are in SAP note 2449067.
A reboot of the server will always be required.
