Qrep distributed apply support log split

Qrep is used to replicate data from z to distributed environment, ICBC found the Qrep apply log keep to increase and cause the difficult in operation management, so they request Qrep to enable the log split function on the apply site. they expect ...

Q Replication to allow add/remove member in P2P replication mesh

As we are migrating our DB workload to the cloud we need to have the ability to add/remove members to redefine our P2P multi-master QReplication topology to accommodate for workload growth and making data available closer to customers (application...

'parallel_mqthread' parameter for Db2 LUW

Customer operates the IRS both on z/OS and LUW. IRS on z/OS supports parallel_mqthread parameter , but that is not supported on LUW. He requests to support it for LUW as well to improve performance.

QREP DDL replication, add UNICODE factor for column length

When replicating from non-unicode to unicode, the legth of char/varchar target columns needs to be extended. Example: create all CHAR/VARCHAR columns at the target with source_length*2 and implemented an additional life belt with OKSQLSTATES = 220...

Single Consistent Tool for Defining and Administering QRep Subscriptions

Consistent and comprehensive client tools are required for defining, administering and operating queue replication. Today the Replication Center and Replication Dashboard exist, and there are some functions that neither of these support and have t...

The customer would like to know all the related tables associated with an uncommitted Unit of Recovery (UR).

If there is an uncommitted UR (a.k.a transaction) on the Capture side, is there a method for QREP to quickly locate the tables related to the uncommitted UR?

Possibility to execute STARTQ command with "CAPTUREUPTO" option

In high workload environments it would be very useful to let QCapture work on a STARTQ command with predefined end. Currently this can be done by a STARTQ command and after the SendQ is active a subsequent STOPQ with captureupto.But if for some re...

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...

ASNCLP should support LARGE tablespaces and AUTOMATIC storage options for Db2

With Db2 11.5 SQL Replication, USING PROMOTE REGISTRATION in ASNCLP to generate a script to run later, the tablespace definitions are created incorrectly for existing tablespaces defined as LARGE and using AUTOMATIC storage. LARGE tablespaces a...

Gracefully handle table failures & send email alert

When a table fails due to structure or availability changes, the replication set should instead set the failed table to inactive instead of crashing capture. It should also send an email notification to alert of the issue.
