The repotools -clean sub-command is used to re-provision repotools and complete the delivery of any new function delivered by the iFix.

As it states in the output from the command:
Tip: The -clean parameter can always be used to force repotools to be reprovisioned.

Hi Kiran,

The latests ifix for 5.0.2 is ifix12 (just as well apply this one while you are at it)
https://jazz.net/downloads/rational-quality-manager/releases/5.0.2/CLM_502_iFix012.zip

the fix contains a readme that should guide you though the installation, But basically its about replacing the fix in the /patch folder of each of your servers running CLM apps. The repotools -clean replaces only content in repotools to make sure that whatever commands you run here is on the same version as your server(s).

You would probably also find files for the rtc eclipse clients in the zip which is usually a p2 installation meaning that you apply these fixes on each client installation from within the rtc eclipse client.
