Patch PE71-0602280
------------------
Platforms: All
* An internal deadlock condition was fixed that could result in
on-line backup requests (dbctl backup start|stop|status) to
hang (#3014). A server shutdown would not succeed in this case
requiring to kill the server process.
An on-line backup request needs to obtain an internal lock to
ensure transactional consistency. If an on-line backup request
gets blocked initially due to a concurrent operation (for example
a dbstore operation is currently running) and another on-line
backup request is issued a deadlock condition occurred that caused
both requests to hang.
* The server process was enhanced to use a more efficient format
to record index and meta data changes.
This enhancement results in a substantial reduction in disk space
for the forward-log file when index entries are changed frequently.
This change required a modification of the forward-log file format.
While older forward-log files are still supported, related utility
programs need to be updated to handle the new format. This requires
installation of additional patches on dbrecover, dblogreset and
fwaudit utilities (see related patches).
* A rare defect with forward-recovery was fixed that could result in
a corrupted volume set (#2999). This causes an internal consistency
check to fail and eloqdb6 to abort on startup with an error message
like below:
Assertion failed: page == new_vol->flist_tail
server panic: Aborting on internal failure, file volume.c, line 3988
This problem could happen if the data volume was extended and the
volume list of available blocks had to be extended as well (this
is required around every 500 MB). The recovery then missed to update
the flist_tail field in the volume header, causing a panic the next
time the server was restarted.
The dbrecover utility was fixed to correctly update the flist_tail
field. In addition the eloqdb6 behavior was modified to detect
and correct this problem on startup. A notice is written to the
server event log file in this case.
* On HP-UX and Linux some log messages regarding eloqdb6 startup and
shutdown were raised in priority so they show up in the server event
log file even if LogFlags=*0 (default) is used. The following
messages are affected:
- "Eloquence database server active" when the eloqdb6 server process
started successfully.
- A new message outputs the current server patch level to the log.
- "Eloquence data base server terminated" when the eloqdb6 server
finished shutdown.
- The message when a new forward-log segment was created.
On all platforms the message indicating a previous unclean shutdown
was recovered is now written to the server log.
Platforms: Windows
* On the Windows platform, dbctl bimport refused an absolute path
beginning with a drive letter (#2997).
* Changed the Windows file version to "7.1.0.7"
