Steps to update Java - QMF for Workstation:
1. Download JRE 8.0.6.25 version from IBM Java download portal.
2. Close QMF for workstation , if any instance is running.
3. Copy 8.0.6.25 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 C:\Program Files\IBM\DB2 Query Management Facility\QMF Vision\elasticsearch\java\jre1.8.0_252.
Note: The folder name would be “jre” in case security bulletin reference # 0880785 is already applied.
5. Copy folder jre1.8.0_282 from the temporary location to C:\Program Files\IBM\DB2 Query Management Facility\QMF Vision\elasticsearch\java.
6. Rename folder jre1.8.0_282to jre.
