Patch PE70-0408312
------------------

Platforms: All

* The commit operations performed by dbrecover have been aligned with
  the changes in eloqdb6 patch PE70-0408310.

Patch PE70-0401162
------------------

Platforms: All

* The commit operations performed by dbrecover have been aligned with
  the changes in eloqdb6 patch PE70-0401160.

This patch (or newer) should be installed when using the corresponding 
eloqdb6 patch PE70-0401160.


Patch PE70-0307162
------------------

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.
