3. Upgrade IBM Tivoli Netcool/OMNIbus WebGUI to the appropriate version that would support the corresponding Websphere Application Server (WAS) fix pack and IBM Jazz for Service Manager (JazzSM) fix pack installed. See table 3, in <https://www.ibm.com/docs/en/netcoolomnibus/8.1?topic=upgrade-web-gui-installation-prerequisites&gt;

* For example, if you are running Websphere Application Server 8.5.5.20 and IBM Jazz Service Manager 1.1.3.13, then you must also upgrade to [IBM Tivoli Netcool/OMNIbus WebGUI 8.1.0.25](<https://www.ibm.com/support/pages/node/6490291> "IBM Tivoli Netcool/OMNIbus WebGUI 8.1.0.25" ).

4. If you are running IBM Tivoli Netcool/OMNIbus WebGUI 8.1.0.11 (or higher), which contains the following file $JazzSMHOME/profile/installedApps/installedApps/JazzSMNode01Cell/isc.ear/OMNIbusWebGUI.war/WEB-INF/lib/log4j-api-2.12..jar. You can either, leave this file as is, because these CVEs only vulnerable by log4j-core, not log4j-api*. Or, follow the steps below to remove this file, which may produce ignoreable non-functional error messages in the log file.

1. Stop the JazzSM server, eg. $JazzSMHOME/profile/bin/stopServer.sh server1
2. Move log4j-api-2*.jar file to an archive directory outside of $JazzSMHOME
3. Start the JazzSM server, eg. $JazzSMHOME/profile/bin/startServer.sh server
