Patch PE83-1909130
------------------
Platforms: All
* Fixed a potential deadlock condition which could happen on a replication
slave server if an FTS query was executed while FTS updates were
replicated (#4263).
Platforms: HP-UX and Linux
* Fixed a problem where some files were not closed on a eloqdb server
panic and automatic restart (#4301).
Platforms: Linux
* Fixed a problem where an eloqdb server panic and automatic restart
could ignore command line arguments.
Patch PE83-1907090
------------------
Platforms: All
* Fixed a rare race condition where enumerating the internal threads
could access a terminating thread (#4061). This could in some cases
result in a failed lock or removal operation.
Threads are enumerated when using the http status or the dbctl list
functionality. An error message as below was logged
T0: [#] pthread_mutex_destroy(p_mutex) failed (errno 16)
T0: [#] pthread_mutex_lock(tcp->p_mutex) failed (errno 22)
D0: [#] server panic: Fatal problem detected in thread__lock
* Sync forward log file changes to disk on a checkpoint. In case
of a system abort this limits data loss in the forward log to the
last checkpoint and ensures replication can be resumed.
Patch PE83-1906240
------------------
Platforms: All
* Fixed a problem where a replication slave server could abort with
a message like below while processing a large transaction (#4292):
Fwr_PageHashAdd() failed: key ... already present ...
server panic: Fatal problem detected in Fwr_PageHash__Add
Assertion failed: Fwr_PageHashAdd() failed: key already present
server panic: Aborting on internal failure, file volfwr.c ...
Notes / Related patches:
* Patch PE83-1906241 or superseding (dbrecover utility) fixes a related
problem and should be installed with this patch.
Patch PE83-1905220
------------------
Platforms: All
* Improved async disk i/o overhead with replication.
* HP-UX: Fixed possible latency problem on I/O completion using Posix
async I/O and replication.
* HP-UX: When using Posix async I/O the configured number of eloqdb
I/O threads ([Config] AIOThreads) is now ignored other than a
non-zero value is used to enable async I/O.
Two threads are used: One thread to handle I/O completion and
a second thread to handle a possible resource shortage when
submitting disk read requests.
Patch PE83-1903040
------------------
Platforms: All
* Fixed database server internal deadlock condition that could in rare
cases result in a hanging server process (#4285).
A deadlock condition was fixed in the database server cache management
that could result in a (partially) hanging server process.
A thread status (dbctl list thread or thread status dumped on shutdown)
indicates a block in the mpool subsystem.
This was caused by a potential lock ordering problem when a cache buffer
was reused by a concurrent connection.
