This is only a guess because you provide very little context. The term "dress rehearsal" is not very commonly used, as far as I know, but it's probably the same thing as a "dry run" or "walk through". My team does dry runs before deployments to make sure we don't miss any details. It's basically a practice run through the deployment procedure, with everyone on the team who will be actively involved in the deployment participating. The release manager goes through his checklist and each person either simulates or does what he/she will be doing such as updating database schemas, deploying ear/war/jar files, updating configurations, making backups, running scripts, checking in documentation, etc. This is done in an environment that is as close as it could possibly be to the target environment.

Yes, these are things that you could expect to check during a dry run. See this definition and the synonyms below it, which includes "dress rehearsal": http://www.thefreedictionary.com/dry%20run
