Mainframe, MVS and zOS Discussion

Hi,

We use Changeman for change control. For any new change-request, we'll identify the COBOL programs impacted and then check-them out in a changeman package. In case there any other parallel requirement which also involves some of the components from requirement one, it becomes a tough process to do the retro-fit all the changes and install both the requirements. As of now the only solution is install one change first, wait and install second change. Can there be a process in which retro-fit can be automatic and the installation goes smooth for both the requirements?

What you do in such cases?

There are some tools on the market for source code management that allow multiple update branches, but they tend to be pretty costly if you don't already own one of them.  Either your group needs to not allow multiple updates to the same program to be happening simultaneously, or the group needs to develop some standard processes for handling such issues. To some degree, this is ALWAYS an issue and different groups resolve it in different ways.

Can you name of some of them? Or give an idea to search on a term in google, my search did not gave me desired results.

In traditional ways like using mainframes, it does not allow multiple updates...or you are saying it might?

My words were referring to different people updating the same source code with different changes at the same time, usually by both of them copying the source to their own library.  This may occur over a period of hours to weeks.  Doing multiple updates to a data set at the same time is just begging for trouble.
