Raj - Can you provide more details? Is this an automated script, or just a
line on the form that says that you have some idea of how to rollback the
change in case anything goes wrong?

And have a similarly tested and signed off rollback strategy in place. An
immediate rollback, as well as a rollback strategy after n number of days.

Please
respond to
ORACLE-L
The releases should be tried in the Development environment first. Then a
UAT (User Acceptance Test) environment, then production. The UAT
environment is usually a duplicate of the production environment. This is
the environment that you implement the changes , then test to see if the
changes worked and if there are any side effects.
The end user , project manager, information owner, or test manager signs
off that the changes were implemented correctly. Then approval is given and
the change is implemented in the production environment. This is usually
accompanied by some sort of change control management. Also, use some sort
of source code control to keep the DML and DDL scripts in. Oracle's SCM
Repository (once part of Oracle Designer), TrueChange by TrueSoft, PVCS,
etc. are candidates for this.
By implementing the scripts in the UAT environment, any dependencies become
evident. Also, the developers should submit the changes in fully runnable
SQL scripts, with
appropriate comments. If the scripts are dependent upon some other script
or database object, this should be listed in the SQL file comment header,
along with the authors name and a description of the file.
Hopefully this will get you going.

Friends ...
I have a (sort of) problem ... what are the best practices to manage code
releases to production environment ...
currently we get a bunch of scripts from development team, and we release
code to production on the schedule (currently twice a month). But this is
not complete. The scripts we get consists of various DML and DDL
statements.
We do not have a mechanism to roll-back these changes in place and I am
seeking your opinion on ways to achieve these. Also we would like to
implement script dependencies (which we manage manually right now) and
rollback mechanism.
Are there any good practices papers? I know these would be site specific,
but I am looking for common methods.
Hope I make myself clear ... (and if it matters it is Oracle 9.2 and
Forms/Reports) application.
Raj
