HP ELOQUENCE A.06.20 - patch 9903240

----------------------------------------------------------------------

This patch fixes a defect of the eloqdb6 program as released
with A.06.20. This patch will be integrated in a subsequent
HP Eloquence release.
A.06.20 must be installed before applying this patch.

This patch replaces patches PE62-9902110, PE62-9902170, PE62-9902221,
PE62-9902222, PE62-9903040 (beta), PE62-9903080 and PE62-9903240 (beta).


Fixed problems:
---------------

Platforms: All

* eloqdb6 could abort with an internal failure.
  Assertion failed: header.size >= addr->size
  server panic: Aborting on internal failure, file volpool.c, line 1985
  Assertion failed: Pool_TestFlag(Pool_BLOCKUSED,&header)
  server panic: Aborting on internal failure, file volpool.c, line 2132

* When a client was disconnected (killed) eloqdb6 could cause a high
  load when the associated internal thread was blocked.

  For example, when eloqcore is blocking on a DBLOCK and is killed
  the eloqdb6 process could busy waiting until the lock becomes 
  available, consuming almost all CPU resources.


Patch PE62-9903080
------------------

Platforms: All

* Crash recovery could cause fixrec meta data corruption.

  This could either cause image status errors status 17 or -96 or lead
  to a eloqdb6 server panic.
  Assertion failed: FixRec_FinalCommitDelete(): record counter inconsistency
  server panic: Aborting on internal failure, file volfrec.c, line 3089

  The dbfsck utlity can be used to verify or correct fixrec meta information.

* Crash recovery could leave unassigned index and system catalog data
  pages. In rare situations, this could lead to data corruption.

* dbctl dbrestore could cause a deadlock.

  When a database is restored, user/group memberships are deleted.
  This could cause a deadlock.


Patch PE62-9902222
------------------

Platforms: All

* DBUPDATE mode 1 on a standalone detail set returned status 41


Patch PE62-9902221
------------------

Platforms: All

* DBFIND/DBGET on index item or QFIND on index item could fail.


Patch PE62-9902170
------------------

Platforms: All

* A race condition could cause a eloqdb6 panic.
  Assertion failed: bhp->id.page_id == ++page_id
  server panic: Aborting on internal failure, file mpool.c, line 415

  This was triggered by a low buffer space condition where a buffer
  page was re-used unexpectedly by the same thread.

* A race condition in Node_Open() could cause a eloqdb6 panic.
  Assertion failed: meta
  server panic: Aborting on internal failure, file volfrec.c, line 2274

  This was triggered by a condition where multiple threads were
  opening a node and the first one was blocked to read the node
  meta data.

* On the HP-UX and Linux platform a server shutdown could cause
  errorneous messages.


Patch PE62-9902110
------------------

Platforms: All

* dbvolcreate utility could output errorneous warnings about
  a possible PIN LEAK.

* The eloqdb6 server process could output errorneous warnings about
  a possible PIN LEAK.

* The dbstore operation failed to release a node lock which could cause
  a subsequent eloqdb6 server panic.

* After opening more than 32767 databases in succession in a single
  session eloqdb6 could provide a possibly wrong or duplicate dbid.
