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_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,
