Workarounds and Mitigations

There are no workarounds except to replace the JRE.

To solve the problem without updating the entire Recovery Expert product, the
user can replace the existing JRE that is installed into the product
installation tree in the jre directory with a newer JRE that includes the
security fixes.

Instructions to replace the IBM JRE for DB2 Recovery Expert for Linux, UNIX
and Windows

1. Identify the version and platform of your DB2 Recovery Expert
installation.

2. See the table below to find the IBM JRE download link that matches your
product version and platform. If you cannot find a JRE download link for your
product version and platform, contact IBM Technical Support and refer to this
tech-note

3. Download the zip file (for example: ibm-java-jre-x.x-x.x-linux-x86_64.tgz)
and extract it to a folder on a local file system (for example: /tmp/ibm-
jre-x.x-x.x).

4. Stop the DB2 Recovery Expert server using the stop.sh command (for
example: /opt/ibm/RE/stop.sh).

5. Back-up and then delete the contents of the jre folder from your product
installation directory (for example: /opt/ibm/RE/jre).

6. Copy the contents of the jre folder from the latest IBM JRE that you
downloaded in Step 3 (for example: /tmp/ibm-jre-x.x-x.x/jre/) to the jre
folder in your product installation directory (for example:
/opt/ibm/RE/jre/).*

7. Ensure that the file permissions for the new JRE files and folders match
the file permissions for the original JRE files and folders. If necessary,
set 775 recursively.

8. Restart the DB2 Recovery Expert server using the start.sh command (for
example: /opt/ibm/RE/start.sh).

* NOTE: You must repeat from Step 6 again any time you install an APAR or
upgrade to an affected version of DB2 Recovery Expert.
