When I checkout the files in clear-case, it gives option to either reserve or unreserved it. What is the advantage of these two options. when to use which one? I usually choose reserved checkout.

Answer 1

Most people dont know that comments can be modified after checkin. Just run this command:

cleartool chevent –replace –c "<Your new comment goes here>" ELEMENT_NAME

this command will completely delete/replace the previous comment with the new comment (obviously if there was a previous comment). You can append to the existing comment by removing the "-replace" argument without losing the previous data.
