---------------------------------------------------------------------- ELOQUENCE B.08.30 - patch PE83-1909130 ---------------------------------------------------------------------- This patch adds enhancements or fixes defects of the eloqdb server as released with Eloquence B.08.30-1810. This patch will be integrated in the Eloquence B.08.30 release. Eloquence B.08.30-1810 must be installed before applying this patch. Severity: PE83-1909130: BUG FIX Superseded patches: PE83-1907090: BUG FIX PE83-1906240: BUG FIX PE83-1905220: BUG FIX PE83-1903040: BUG FIX Patch PE83-1909130 ------------------ Platforms: All * Fixed a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.
