Uninstall the Liberty profile application-serving environment from IBM i operating systems

By calling the iAdmin PREUNINSTALL command, we can remove any IBM i native objects and libraries created by the iAdmin POSTINSTALL command. Then we can manually remove the files comprising the Liberty profile application-serving environment.

After installing the Liberty profile application-serving environment by executing a JAR file on IBM i, we might have used the iAdmin POSTINSTALL command to configure the Liberty profile server to launch as a job in the QWAS85 subsystem and to run under the QEJBSVR user profile. If so, we must remove the IBM i native objects and libraries created at that time before you manually remove the files that comprise the Liberty profile application-serving environment.

We must have *ALLOBJ and *SECADM special authority to use the iAdmin POSTINSTALL command.

1. On the IBM i command line, run the STRQSH command to start the Qshell.

2. In the resulting Qshell session, change the directory to the wlp directory.
   lib/native/os400/bin/iAdmin PREUNINSTALL
