Affected Products and Versions

Platform Cluster Manager Version 4.2.0, 4.2.0.1, 4.2.0.2 and 4.2.1

Platform HPC Version 4.2.0 and 4.2.1

Spectrum Cluster Foundation 4.2.2

Remediation/Fixes

1. Download IBM JRE 7.0 x86_64 from: <http://www.ibm.com/support/fixcentral&gt; by keyword ‘Runtimes for Java Technology’. (For POWER platform, you need to download ppc64 version JRE tar package. The following steps use x86_64 as an example.)
2. Copy the tar package into the management node. If high availability is enabled, copy the JRE tar package to standby management node, as well.
3. If high availability is enabled, shutdown standby management node to avoid triggering high availability.
4. On the management node, stop GUI and PERF services.

pcmadmin service stop --group ALL

5. On management node, extract new JRE files and replace some old folders with new ones.

chmod +x ibm-java-x86_64-jre-7.0-10.50.bin

./ibm-java-x86_64-jre-7.0-10.50.bin

mv /opt/pcm/jre/bin /opt/pcm/jre/bin-old

mv /opt/pcm/jre/lib /opt/pcm/jre/lib-old

mv /opt/pcm/jre/plugin /opt/pcm/jre/plugin-old

cp -r ibm-java-x86_64-70/jre/bin /opt/pcm/jre/

cp -r ibm-java-x86_64-70/jre/lib /opt/pcm/jre/

cp -r ibm-java-x86_64-70/jre/plugin /opt/pcm/jre/

mv /opt/pcm/web-portal/jre/linux-x86_64/bin /opt/pcm/web-portal/jre/linux-x86_64/bin-old

mv /opt/pcm/web-portal/jre/linux-x86_64/lib /opt/pcm/web-portal/jre/linux-x86_64/lib-old

mv /opt/pcm/web-portal/jre/linux-x86_64/plugin /opt/pcm/web-portal/jre/linux-x86_64/plugin-old

cp -r ibm-java-x86_64-70/jre/bin /opt/pcm/web-portal/jre/linux-x86_64/

cp -r ibm-java-x86_64-70/jre/lib /opt/pcm/web-portal/jre/linux-x86_64/

cp -r ibm-java-x86_64-70/jre/plugin /opt/pcm/web-portal/jre/linux-x86_64/

6. On management node, start GUI and PERF services.

pcmadmin service start --group ALL

7. If high availability is enabled, start up standby management node, and replace bin, lib, plugin folders under /opt/pcm/web-portal/jre/linux-x86_64, on standby management node.

Workarounds and Mitigations

None.
