  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
