Replication: Q-Replication & Availability

Showing 70 of 14269

Improvement of QREP to allow replication of data generated in the Db2 LOG by the LOAD utility with SHRLEVEL NONE LOG YES.

Need: Meet the growing demand for data replication from Banco do Brasil -Scenario:- Banco do Brasil is a large user of data replication using Qrep (IIDR) + Db2 v13 for z/OS, there are thousands of tables replicated from production environments for...

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...

SQLCA -904 not offload on Infosphere Q-Replication job log on z/os

QREP didn’t externalize the SQLCA error -904 on Prod DB2.. Since we dont have a SQL error Monitoring tool on one of the BU Prod db2 enabled.. So debugging the issue was difficult.. There should be some repository/documentation where this SQLCA err...

Data captured in long transactions with guaranteed delivery to destination

It is usefull because sometimes a very long transaction pass through the Capture process but can´t be delivered causing memory lack at destination. The benefit would be not losing the data transferred to the destination. One suggestion would be to...

Feed Q Replication with your own LOAD keywords for automatic load

Recently we had opened a case TS013850174, which could not be addressed correctly b/c it requires an enhancement. Problem was as follows. Due to an error in our change management process, target table had a unique index, which was not present at t...

Provide High Availability Solution

If you currently have QCapture tasks executing on an LPAR and the LPAR or Db2 member on the LPAR crashes, there will be an outage and latency. In an environment where we are executing an n-way Db2 Datasharing group replicating to a highly availabl...

Q Capture/Db2 LUW: Replicate DROP COLUMN-operations

If the source table of an active subscription is altered by a DROP COLUMN operation, there is high risk of continuous data corruption on that table due to incorrect reading of Db2's transaction log entries from that time on. The current workaround...

Q-Capture (on LUW) supports to use a dedicated MQ publish thread to perform all IBM MQ operations...

Currently, there is "parallel_mqthread" && "mqthread_bufsz" parameters, but it only used on z/OS. Cx hopes these features can support on LUW as well, which can specify whether the Q Capture program should use a separate thread to publish m...

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...
