Remediation/Fixes
Steps to update Java - QMF for Workstation:
1. Download JRE 8.0.6.10 version from IBM Java download portal.
2. Close QMF for workstation , if any instance is running.
3. Copy 8.0.6.10 JRE version to C:\Program Files\IBM\Db2 Query Management Facility\QMF for Workstation\jre.
4. Start application
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 contents of folder - C:\Program Files\IBM\DB2 Query Management Facility\QMF Vision\elasticsearch\java\jre1.8.0_131.
Note: The folder name would be “jre” in case security bulletin reference # 0880785 is already applied.
5. Copy content of downloaded jre from the temporary location (step # 2) to C:\Program Files\IBM\DB2 Query Management Facility\QMF Vision\elasticsearch\java.
6. Rename folder jre1.8.0_131 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_131" 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
