Affected Products and Versions

Remediation/Fixes

Please see “Workarounds and Mitigations”

Workarounds and Mitigations

Use the following instructions to download the latest JRE version from the IBM Java download portal and replace it with the JRE you are currently invoking.

Steps to update Java - QMF for Workstation:

1. Download JRE 8.0.8.30 version from IBM Java download portal.

2. Close QMF for workstation, if any instance is running.

3. Copy 8.0.8.30 JRE version to C:\Program Files\IBM\Db2 Query Management Facility\QMF for Workstation\jre. (QMF install directory)

4. Start application

Observations:

1. While updating java in QMF for workstation for z/OS and Multiplatform build versions from 12.2.0.1 to 12.2.0.4 will reflect some issue for scheduled tasks after java update. Please update to QMF 12.2.0.5 before applying the java update for scheduled tasks to run without any issues.
2. After migrating to QMF 12.2.0.5, update the java using above steps. To run Visual Reports, please set below 3 VM arguments in C:\Program Files\IBM\Db2 Query Management Facility\QMF for Workstation\eclipse.ini (QMF install directory)

-Djdk.xml.xpathExprGrpLimit=0

-Djdk.xml.xpathExprOpLimit=0

-Djdk.xml.xpathTotalOpLimit=0

Steps to update Java - QMF Vision:

1. Go to: https://adoptopenjdk.net/releases.html

2. Download Open JDK 8(LTS) and extract the files to a temporary location.

3. Stop the following Windows services:

- IBM QMF Vision Indexing Service (this will also stop IBM QMF Vision Web Service due to dependencies)

- QMFServerLite

4. Delete C:\Program Files\IBM\DB2 Query Management Facility\QMF Vision\elasticsearch\java\jre 1.8.0_362. (QMF Vision install directory)

Note: The folder name would be “jre” in case security bulletin reference # 0880785 is already applied.

5. Copy folder jre 1.8.0_422 from the temporary location to C:\Program Files\IBM\DB2 Query Management Facility\QMF Vision\elasticsearch\java. (QMF Vision install directory)

6. Rename folder jre 1.8.0_422 to jre.

Note: If the folder in the java folder is already renamed to “jre” via the security bulletin reference # 0880785, then steps 7 through 12 are not required. You can directly go to step 13 and start the relevant services,

Security bulletin # 0880785 link - https://www-01.ibm.com/support/docview.wss?uid=ibm10880785

7. Under C:\Program Files\IBM\DB2 Query Management Facility\QMF Vision, edit the following 6 files:

elasticsearch/bin/install.bat

elasticsearch/bin/start.bat

elasticsearch/bin/stop.bat

elasticsearch/bin/uninstall.bat

qmfserver/bat/setenv.bat

qmfserver/conf/wrapper.conf

For each file, replace “jre1.8.0_362” with “jre”, and save.

8. Open a Windows Command window in Administrator mode and Change directory to elasticsearch/bin.

9. Execute:

uninstall.bat

install.bat

10. Change directory to qmfserver/bat.

11 Execute:

uninstallService.bat

installService.bat.

12. In the Windows Services console, edit “IBM QMF Vision Indexing Service” to change startup type from “Manual” to “Automatic”.

13. Restart Windows Services:

- IBM QMF Vision Indexing Service

- IBM QMF Vision Web Service

- QMFServerLite.
