I have successfully install RTC 3.0 build function on V5R4. I want to remove the LICPGM after evaluation expire. But I couldn't found any document mention about how to remove it. Can anybody help me?

You can remove the Build System Toolkit on IBMi using the DLTLICPGM command. For example, the following IBMi command:

DLTLICPGM LICPGM(5733JTS) OPTION(*ALL)

...will unininstall all currently-installed Jazz Team Server and Build System ToolKit LICPGM options on the IBMi server.

If you just want to uninstall the BSTK, and leave other installed Jazz Team Server components on IBMi, enter: DLTLICPGM LICPGM(5733JTS) OPTION(3).

Note: if you're planning on upgrading from a trial license to a permanent license, there's no need to uninstall/reinstall the BSTK - the licenses are registered in the Jazz Team Server, not the BSTK.
