Q Replication for Z

Showing 64 of 18068

Let Capture build the transaction message with non-LOB columns first and LOB columns last instead of in strict column sequence order.

Please consider changing Capture to build transaction messages with all non-LOB data first, then add on the LOB data after all other non-LOB data no matter what the sequence numbers. This would prevent the risk of splitting a message on non-LOB da...

Identify major LOG captures.

We frequently experience delays in QREP Capture readings on our peak processing days without any apparent monster transactions. Transactions and rows continue to be processed, but at a slower rate than the actual log reads. In these cases, we have...

zIIP Eligible Q-APPLY

Currently the SQL Queries in QREP Apply are CPU-intensive. The CPU cost of those queries cost more than our top 5 application programs combined. We recommend to make Q APPLY Queries zIIP eligible to reduce the CPU cost for QREP APPLY.

Be able to add options in the cross-LOAD command executed by QREP, during a refresh of target tables

Hello there, I have opened one IBM case for this topic. What is the point: We have some troubles with QREP replication.When QREP is trying to do a LOAD REPLACE (via stored procedure DSNUTILU), in the target table, if someone is using the targe tab...

Separate offerings for Q rep and CDC instead of bundle

From a product patch/maintenance standpoint, the management of these 2 products has been difficult because they both resolve to one product name. But each product has their own maintenance fixes, separate SMP zones, and separate patch scheduling i...

In SQL replication, do not re-execute signals that have already been executed.

In SQL replication, as in Q Capture, add a reprocess_signals to the parameters of the capture and set the default to N. Do not re-execute a signal that has already been executed if the minimum LSN is less than the last signal LSN at the start of t...

Implement more granularity processing on "CORRELID" to force more parallelism at Q Apply

We have an application with a high criticality and high workload running Q Replication in a bidirectional mode.This application uses CICS transactions, TSO Batch, Java Batch, local zWAS and distributed transactions as well.And because batch jobs c...

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?

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...
