ELOQUENCE B.07.00 - patch 0307162

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

This patch fixes a defect of the dbrecover utility as released
with Eloquence B.07.00. This patch will be integrated in the
Eloquence B.07.00 release.

Eloquence B.07.00 must be installed before applying this patch.

This patch replaces patch PE70-0305091.

Severity:
 PE70-0307162: CRITICAL (panic during recovery)
 PE70-0305091: CRITICAL (panic during recovery)


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

Platforms: All

* dbrecover was enhanced to improve recovery performance (#1988)
  dbrecover uses temporary files to collect all changes which belong
  to a single transaction. This handling was optimized, resulting in
  a dramatic performance increase on HP-UX (and to some lesser extent
  on other platforms).

* dbrecover was fixed to handle a situation where the database server
  crashed and wrote incomplete information to the forward log (#1966).
  While dbrecover makes sure only complete transactions are applied a
  rare corner case could lead to (unused) data blocks linked to a table
  but not marked in use. This could lead to subsequent data corruption.

* dbrecover could abort with an internal error when schema is executed
  immediately after a dbpurge (#2053)

  panic: Fatal problem detected in bf_link_cluster
  Assertion failed: f_bhp->id.node_id == node_id
  Aborting on internal failure, file mpool.c, line 408


Patch PE70-0305091
------------------

Platforms: All

* dbrecover could abort with an internal error (#1948).

  panic: Fatal problem detected in FixRec_FinalCommitDelete
  Assertion failed: data_addr
  Aborting on internal failure, file volfrec.c, line 3126

  NOTE: In case dbrecover aborts the forward recovery needs to
  be restarted from the beginning by restoring the backup and
  running dbrecover again.
