---------------------------------------------------------------------- ELOQUENCE B.08.30 - patch PE83-2005180 ---------------------------------------------------------------------- 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 Severity: PE83-2005180: BUG FIX Superseded patches: PE83-2005070: BUG FIX PE83-2001240: BUG FIX PE83-1910230: BUG FIX PE83-1909130: BUG FIX PE83-1907090: BUG FIX PE83-1906240: BUG FIX PE83-1905220: BUG FIX PE83-1903040: BUG FIX Patch PE83-2005180 ------------------ Platforms: All * A dbupdate with no changes was not reflected in the forward log but simply ignored (#4316). This could be unexpected for an application that relies on this. * Fixed a potential unexpected status 15 of FTS DBGET modes 25, 26 moving to the first or last result on an aggregated index. Platforms: Windows * Fixed a potential internal timer value overflow after 49 days (#4315). Patch PE83-2005070 ------------------ Platforms: All * Fixed unexpected status 15 returned by the FTC ODXGET call. The correct status 888:310/311 is now returned. * Fixed unexpected behavior of ODXGET call when skipping search results or changing fetch direction. The ODXGET behaves the same when skipping or reading results. * Fixed unexpected behavior with FTS DBGET modes 22, 23, 25, 26 when skipping results or changing fetch direction. Patch PE83-2001240 ------------------ Platforms: Windows * Fixed a problem where the eloqdb process did not have enough time to gracefully stop when Windows is shut down or restarted. Patch PE83-1910230 ------------------ Platforms: All * Fixed an FTS index problem that could affect databases migrated from B.08.20. This may affect databases using FTS indexes created with B.08.20 that were subsequently restructured with B.08.30. Restructuring a database created with B.08.20 enables additional FTS features, not available previously. This could result in an unexpected index structure that could result in inconsistencies for keywords with a large number of references. Subsequently adding records could result in FTS index inconsistencies. Databases where the FTS indexes were created or rebuilt with B.08.30 or that were not restructured are not affected. Installing this patch will prohibit additional FTS index inconsistencies. However, if an FTS index is affected, it must be rebuilt. The checkfts utility (available for download in the contrib directory) may be used to verify the FTS index consistency. 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.
