New Issues Reported
- Qlik Replicate and R4Z after upgrade to 2023.5 SP02: additional download required
The Qlik Replicate service pack 02 release for 2023.5 includes old R4Z installation files from the previous SP01 build.To upgrade the R4Z component, additional files need to be downloaded and installed. See Qlik Replicate and R4Z after upgrade to 2023.5 SP02: additional download required for details.
- SQL0551N The statement failed because the authorization ID does not have the required authorization or privilege to perform the operation.
Qlik Replicate with a DB2 z/OS source endpoint (using R4Z) displays authorization and privilege errors. See Qlik Replicate DB2 z/OS - [SOURCE_CAPTURE ]E: RetCode: SQL_ERROR SqlState: 42501 NativeError: -551 M... for more information and how to resolve the issue.
Tips!
- R4Z Db2 mainframe install is completed but no Changes are coming through
Check that the Tables you wish to be performing CDC replication upon, have been "turned on" for capturing the changes from the DB2 z/OS Logs. See Qlik Replicate: R4Z DB2z No CDC coming through for details. - Qlik Replicate DB2 z/OS task may stop/fail with R4DB2: ALL CB ENTRIES ARE IN USE
This means that a task is trying to start, but the maximum number of R4Z Control Blocks (in the R4Z CDC service environment on the mainframe) is in use. Find the resolution in Qlik Replicate: DB2 z/OS R4Z [SOURCE_CAPTURE ]W: R4DB2: ALL CB ENTRIES ARE IN USE.
Best Practice
- Match R4Z and Qlik Replicate versions
The Qlik Replicate and R4Z versions you install must be part of the same release, which can either be an initial release or a patch/service release. This means that if you upgrade Qlik Replicate, you must also upgrade your R4Z installation (to the version that correlates with the Qlik Replicate release you are installing), unless it has the same build number as your currently installed R4Z. Note that despite being part of the same release, the Qlik Replicate and R4Z build numbers (reflected in their file names) might not be the same.
For example, Qlik Replicate May 2022 SR2 includes the following files:
- QlikReplicate_2022.5.0.499_X64.zip (the Replicate installer)
- QlikReplicate_2022.5.0.290_r4z.zip (the R4Z installer).
- How to avoid WLM tasks being cancelled due to Work Load Manager Policy settings
When installing and using the DB2 z/OS endpoint in Qlik Replicate, WLM tasks on the mainframe may get cancelled. There are multiple root causes for this, but a common one can be addressed by reviewing the execution priority (WLM settings).
See Qlik Replicate and R4Z: Best practice to ensure DB2 z/OS Workload Manager (WLM) tasks are not cancel... for details.
