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

This patch enhances or fixes defects of the eloqdb server as

Severity:
 PE82-1312160: BUG FIX

Superseded patches:
 PE82-1312040: BUG FIX


Patch PE82-1312160
------------------

Platforms: HP-UX

* Fix a potential performance regression on HP-UX introduced with 
  "vnode" locking changes in patch PE82-1312040.


Patch PE82-1312040
------------------

Platforms: All

* Fixed a lock starvation issue that could happen under a specific
  workload. This might cause eloqdb threads to be blocked for
  an undefined period waiting on the internal "vnode" lock.
  This should only affect large systems under high load.

* Improved scalability of the internal "vnode" lock.  The internal
  "vnode" lock could impact performance and CPU consumption under
  some workloads if the vnode lock is contended.

* Fixed a B.08.10 interoperability problem that caused a status
  -700:-7 when opening a B.08.20 database using B.08.10.
