Question

package locking

Asked by: hans_vd

Today a developer added a column to a very frequently used table in our production environment, which caused a number of packages to get invalid.

One package did not compile, our developer tool hung and after a while we got a time-out message.  We couldn't come up with anything better (and we needed a solution quickly) than killing all processes in the database that were using the package (we got that info from dba_ddl_locks), and then recompile the package successfully.  As our users weren't really amused, we'd like to come up with a better solution in the future, if there is one?

We already blocked access to our production environment for part of the developers, but still this could happen to others.

Does any of you know how to handle this kind of problems in a better way?

In the practice, the developers works on shared developer database, when the developer finish your work then, your scripts run in pre-production database.

The aplication pointer move to pre-production database, when the users certificate then migrate to production database.


For your problem describe , your resolution is the only way, I think so, for fixed this inconvenient.

We've had the same problem occasionally (and it seems to be worse now that we are on Oracle10.1 than it was on Oracle8 or 9) so we don't allow changes to heavily-used tables in our prodution database during the week anymore.  We have the luxury of production down time on Saturday night and Sunday, so we wait with structure changes to our production database until the weekend, when we can shut down and reboot the instance if necessary to clear locks on PL\SQL objects.

Ok, seems like we need to try to prevent this problem from coming up, rather then to solve it.

Thx
