Workarounds and Mitigations
Platform Cluster Manager 4.2.x & Platform HPC 4.2.x
1. Download Apache Commons Collections 3.2.2 from http://commons.apache.org/proper/commons-collections/download_collections.cgi
2. Extract the file commons-collections-3.2.2.jar file and copy the extracted files to the management node.
3. Back up your existing JAR files and replace them with the Apache Commons Collections 3.2.2 files. The existing JAR files that need to be replaced, include:
· /opt/pcm/web-portal/perf/1.2/lib/commons-collections-3.1.jar
· /opt/pcm/web-portal/gui/3.0/wlp/usr/servers/platform/apps/platform.war/WEB-INF/lib/commons-collections-3.2.1.jar
· /opt/pcm/web-portal/docs/kc.war/WEB-INF/lib/commons-collections-3.2.1.jar
· /opt/pcm/activemq/lib/optional/commons-collections-3.2.1.jar
· /opt/pcm/pcmd/1.0/lib/external/commons-collections-3.2.1.jar
If high availability is enabled, in addition to the above files, replace the following JAR file on the standby management node.
· /opt/pcm/activemq/lib/optional/commons-collections-3.2.1.jar
4. Restart services. If high availability is enabled, run the following commands on active management node:
# pcmhatool failmode -m manual
# pcmadmin service stop --group all
# pcmadmin service start --group all
# pcmhatool failmode -m auto
Otherwise, if high availability is not enabled, run the following commands on the active management node:
# pcmadmin service stop --group all
# pcmadmin service start --group all
Platform Cluster Manager 4.1.x & Platform HPC 4.1.x
1. Download Apache Commons Collections 3.2.2 from http://commons.apache.org/proper/commons-collections/download_collections.cgi
2. Extract the commons-collections-3.2.2.jar file and copy the extracted files to the management node.
3. Back up your existing JAR files and replace them with the Apache Commons Collections 3.2.2 files. The existing JAR files that need to be replaced, include:
· /opt/pcm/web-portal/perf/1.2/lib/commons-collections-3.1.jar
· /opt/pcm /web-portal/perf/1.2/lib/commons-collections-3.2.1.jar
· /opt/pcm /web-portal/gui/3.0/tomcat/webapps/platform/WEB-INF/lib/commons-collections-3.2 .1.jar
4. Restart services. If high availability is enabled, run the following commands on active management node:
# pcmhatool failmode -m manual
# pmcadmin stop
# perfadmin stop all
# perfadmin start all
# pmcadmin start
# pcmhatool failmode -m auto
Otherwise, if high availability is not enabled, run the following commands on the active management node:
# pmcadmin stop
# perfadmin stop all
# perfadmin start all
# pmcadmin start
