I'm looking for a good way to migrate changed code from development to test to production servers, for a group of less than a dozen developers. Right now, we use TOAD with team coding. The problem is that sometimes a developer will lock the package, make some changes, move it to development or test, then it gets stuck. If I need to alter the package, I have no choice but to wait for it to complete testing, be rolled out to production, then the team coding lock released. Do you have any suggestions on how multiple people can concurrently work on packages? Thanks.
