Below are steps to update Java - QMF Workstation  and  QMF Vision

 

Steps to update Java - QMF for Workstation:

1.             Download JRE 8.0.6.35 version from IBM Java download portal.

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

3.             Copy 8.0.6.35 JRE version to C:\Program Files\IBM\Db2 Query Management Facility\QMF for Workstation\jre.

4.             Start application.


Note:

Users of QMF for Workstation (v12.2.0.1 – v12.2.0.4) must upgrade to version 12.2.0.5 before applying this Java upgrade.

This is required for scheduled tasks to work seamlessly after the Java Update.


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:
    1. IBM QMF Vision Indexing Service (this will also stop IBM QMF Vision Web Service due to dependencies)
    2. QMFServerLite
  1. 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.
  2. Copy folder jre 1.8.0_302 from the temporary location to C:\Program Files\IBM\DB2 Query Management Facility\QMF Vision\elasticsearch\java.
  3. Rename folder jre 1.8.0_302 to jre.
    1. 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,
    2. Security bulletin # 0880785 link - https://www-01.ibm.com/support/docview.wss?uid=ibm10880785
  4. Under C:\Program Files\IBM\DB2 Query Management Facility\QMF Vision\, edit the following 6 files:
    1. elasticsearch/bin/install.bat
    2. elasticsearch/bin/start.bat
    3. elasticsearch/bin/stop.bat
    4. elasticsearch/bin/uninstall.bat
    5. qmfserver/bat/setenv.bat
    6. qmfserver/conf/wrapper.con
  1.  
    1. For each file, replace "jre1.8.0_302" with "jre", and save.
  1. Open a Windows Command window in Administrator mode and Change directory to elasticsearch/bin.
  2. Execute:
    1. uninstall.bat
    2. install.bat
  3. Change directory to qmfserver/bat.
  4. Execute:
    1. uninstallService.bat
    2. installService.bat.

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