Recover should better support offline backups

Recover should better support offline backups. Using a log archive mode database it is possible to restore an offline backup using recover. It is necessary to specify the 'End Time' of the offline backup, otherwise recover would choose an older ba...

COMMIT NOWAIT

COMMIT NOWAIT could be used to accelerate commit processing (releasing locks while log data not yet written to disk nor transferred to HADR standby) . There are applications that know how to restart their database transaction in case the transacti...

Allow federation like access to HADR RoS

Implicit have federation like access to HADR standby would help application developers to take advantage of RoS standby feature to offload workload.Same connection, same authorization, but with STANDBY.. accessing the tables on standby would be cr...

Avoid SQL1246N for incremental backup

This sqlcode SQL1246N is send by DB2 during an incremental backup each time a new tablespace has been created and no full backup of this tablespace has been done. It shoud be more interesting to switch automatically for this tablespace from the in...

Remove EACCES errors when restoring into different instance on same machine

When restoring a database without automatic storage with redirected restore on a machine where the former tablespace paths exist (but are owned by another UID) the redirected restore generates multiple "EACCES (13) PERMISSION DENIED ERRORS" within...

adjust card estimates on predicates using both COL = '?' and COL > <value> similar to accounting for NUMNULLS

Component: DB2 optimizer When a column is NULLable, a predicate COL = ? will account for numnulls to estimate cardinality. The problem comes when column is NOT NULL, and "the NULL value" is a real value. Peoplesoft has been designed to use a major...

Bufferpool Purge without database deactivation

Ability to purge the bufferpools (perhaps specified by bufferpool name) without deactivating the entire database. While dirty pages can be flushed from bufferpools with the flush bufferpools command, the bufferpools cannot be entirely purged witho...

Improved Db2 backup thread (db2bm and db2med) binding/distribution on NUMA systems

On a large NUMA systems with a very fast storage and a fast backup target memory affinity might affect backup time as well as the overall system performance during the activity. Currently, with the Db2's automatic thread NUMA binding (DB2_RESOURCE...

TIMESTAMP with TIMEZONE

Competitive databases like Oracle, PostgreSQL and SQL Server along with others have data type TIMESTAMP with TIME ZONE but LUW does not. Our own DB2 on z/OS starting version V11.0 has TIMESTAMP WITH TIMEZONE.
