Updating JRE for Rational Directory Server (Tivoli) 5.2.1

Question & Answer


Question

How can I update the JRE used with Rational Directory Server 5.2.1?

Cause

Rational Directory Administrator bundles an IBM SDK for Java (JRE) that is based on the Oracle™ JDK. IBM releases critical patch updates (CPU) based on Oracle's CPU updates which contain security vulnerability fixes for the JRE.
You can install Rational Directory Administrator 5.2.1 with Rational Directory Server 5.2.1.

Answer


Steps to update JRE on Windows Systems:

1. Download the updated JRE package from the IBM Support website. The link is in the Security Bulletin.

2. Extract the new JRE file to a folder.
Example: D:\setups\JAVA\8.0.m.n\ibm-java-jre-80-win-x86_64

3. Close all instances and folders of RDA 5.2.1 version. Upgrade may fail if any instance is running.

4. Stop the RDA WebAppsServer:

    1. Open the command prompt and navigate to the WLP bin folder location: <RDS_5.2.1_InstallationDirectory>/WebAppsServer/WLP_8.x/bin/
      Example: C:\Program Files(x86)\IBM\Rational\ RDS_5.2.1\ WebAppsServer\ WLP_8.x\bin
    2. Run the following command : server.bat stop. If you have already stopped the server, you will see either of the following messages:
      Server defaultServer stopped or Server defaultServer is not running.
    3. Close the command prompt.
5. Open and edit the server.bat file present in the WLP bin folder.

6. Search for the line: set JAVA_HOME= <JRE_PATH>

7. Replace the existing <JRE_PATH> with the new JRE Path:


    Example: set JAVA_HOME=D:\setups\JAVA\8.0.m.n\ibm-java-jre-80-win-x86_64

8. Save and close the server file.

9. Run the clean command and start the RDA WebAppsServer:

    1. Open the command prompt and navigate to the WLP bin folder.
    2. Run the command : server run --clean. You will see the following message:
      The server defaultServer is ready to run a smarter planet.
    Steps to update JRE on Linux Systems:

    1. Download the updated JRE package from the IBM Support website. The link is in the Security Bulletin.
    2. Extract the new JRE file to a directory.
      Example: /setups/Java/8.0.m.n/ibm-java-x86_64-80
    3. Close all the instances and directories of RDA 5.2.1 version. Upgrade may fail in case any instance is running.
    4. Stop the RDA WebAppsServer:
      a. Open the terminal and navigate to the WLP bin directory location: <RDS_5.2.1_InstallationDirectory>/WebAppsServer/WLP_8.x/bin/
        Example: /var/IBM/Rational/RDS_5.2.1/WebAppsServer/WLP_8.x/bin
      b. Run the following command : ./server stop. If you have already stopped the server, you will see one of the following messages:
      Server defaultServer stopped       or Server defaultServer is not running.
      c. Close the terminal.
    5. Open and edit the server file present in the WLP bin directory.
    6. Search for the line: set JAVA_HOME= <JRE_PATH>
    7. Replace the existing <JRE_PATH> with the new JRE Path:
      Example: set JAVA_HOME=/setups/Java/8.0.m.n/ibm-java-x86_64-80
    8. Save and close the server file.
    9. Run the clean command and start the RDA WebAppsServer:
      1. Open the terminal and navigate to the WLP bin directory location
      2. Run the command : ./server run --clean. You will see the following message:
        The server defaultServer is ready to run a smarter planet.
