· /opt/pac/perf/1.2/lib/commons-collections-3.1.jar

· /opt/pac/gui/3.0/wlp/usr/servers/platform/apps/platform.war/WEB-INF/lib/commons-collections-3.2.1.jar

· /opt/pac/gui/3.0/wlp/usr/servers/platform/apps/platform.war/WEB-INF/lib/commons-collections-3.2.2.jar

If high availability is enabled, replace the above JAR file on the all Application Center Server nodes.

4. Restart services. If high availability is enabled, run the following commands on the active management nodes.

# perfadmin stop all

# pmcadmin stop

# perfadmin start all

# pmcadmin start

If high availability is not enabled, run the following commands on the all Application Center Server nodes.

# perfadmin stop all

# pmcadmin stop

# perfadmin start all

# pmcadmin start
