IBM WebSphere - Resolve "Server launched but failed initialization"

Let's say you are getting "Server launched but failed initialization" when attempting to start an IBM WebSphere network deployment manager, node, or application server. This error should be logged to the ${WAS_INSTALL_ROOT}/profiles/<your profile>/logs/<your server>/startServer.log.

For example, this error might appear when using the script (on Linux) to start an application server, or when using the script to start a deployment manager, or when using the First steps console after installing WebSphere using the GUI.

ADMU3011E: Server launched but failed initialization. Server logs,
           startServer.log, and other log files under


I often find the startServer.log to not have the root cause of the startup failure. Instead, I typically find something useful in the other log files in the same directory as the startServer.log.

You may want to issue the or scripts with the -trace flag.

${WAS_INSTALL_ROOT}/profiles/your_dmgr_server/bin/ -trace


In this example, when selecting Installation verification, the end of the log file contains error ADMU3001E: Server launched but failed initialization.


Check the /opt/IBM/WebSphere/AppServer/profiles/<your_profile>/logs/<server>/SystemOut.log file for events with E, which indicates error. For example, let's say the log file contains the following.

VariableExpan E WSVR0244E: An undefined HOST product variable has been encountered in the krb5Spn property of the /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/config/cells/nullNode01Cell/security.xml#KRB5_1 configuration object.
