APAR status

  • Closed as program error.

Error description

  • This APAR deals with the following related issues:
.
1) During authentication, DB2 UDB saves the authentication
information (e.g. groups) to a list located in memory. It has
been discovered that on several occasions, for example during
memory allocation failures, the list is handled improperly.
This may result in potential memory corruption and/or instance
crashes in DB2 UDB authentication routines. The exact external
symptoms of the problem are not yet known. The purpose of this
APAR is to improve the handling of the in-memory list.
.
2) This APAR also improves the diagnostic data gathered
during problems in DB2 authentication routines. This will
simplify future investigations of such problems.
