Db2 LUW - SQL replication should optionally use TRUNCATE when performing a Full Refresh of large tables

Db2 LUW SQL Replication (10.2.1) When you run a Full Refresh of a subscription set, the asnapply utility issues a DELETE FROM <target table> prior to the refresh of the data. For large tables this has a significant and unnecessary overhead -...

Prompt customer need to reduce prune interval

In a busy Q Rep env with many bi-di Q subs, there may lots of P2PNORECAPTURE signal insert into IBMQREP_SIGNAL control table by Q Apply program. As per design, Q Capture delete up to 10000 rows at a time for one prune interval. When the average P2...

Fully replication support of Db2 data type XML with IDR Queue Replication especially for the case the Queue message size is limited because of using Shared Queues based on Coupling Facility structures

We replicate a lot of changes of our operational zDb2 data to a Db2 LUW (BLU) via IDR Queue Replication. The Db2 BLU is used as the data base of our datawarehouse processes. The Queue Replication uses Shared Queues which are mapped on Coupling Fac...

Sequence Number management in a replicated DB2 system

Today sequence numbering in a DB2 subsystem that is being replicated to a secondary site needs to be managed outside of the replication support manually by the customer. Guidance has been given to use odd/even numbering on one side and the other. ...

ASNCLP PROMOTE to generate SQL rather than another ASNCLP Script

When using the ASNCLP PROMOTE function the output is another ASNCLP Script. We would like the PROMOTE option to generate the target SQL instead of another ASNCLP Script - applying any name changes defined in the PROMOTE command.

V12-CERT-2017 - Support for replication of REORG DISCARD events

When a REORG discard is run on the source side in a replication relationship / event relationship we want to be able to replay this event on the target side somehow. We do not want to do this by logging the discards in the REORG, of course. One su...

Ignore log records for a dedicated subscription in IGNORETRANS

In very rare cases Db2 cannot provide log records for Q Capture, e.g. in case of a version mismatch, a compression dictionary error, etc. Removing the subscription and reloading the target is a practical approach. But in some situations (e.g., non...

Latency Threshold Setting by Duration in ASNMON

Transaction volume is different between business time and non-business time. Different threshold should be set for QCAPTURE_LATENCY， QAPPLY_EELATENCY， QAPPLY_LATENCY, e.g. 08:00 - 21:59, 22:00-07:59, etc.

ASNCLP Error Message Enhancement

For error code ASN1952E, the reason maybe ASNCLP script grammar error, QMGR setting is wrong of missed in PARM table of CAPTURE or APPLY, password of z/OS user is wrong, etc. That makes operation maintenance very hard for trouble shooting. The det...

zIIP Eligible Q-APPLY

QREP is increasingly become to a key infrastructure component for customers z Systems platform resilience. However, the QREP did need quite a lot MIPS to support. This requirement is for QREP to change some part to be zIIP eligible, specifically f...
