Home -> Community -> Mailing Lists -> Oracle-L -> RE: Moving Code to Production
Has anyone on this list *actually* used Oracle's Change Management pack in
OEM to manage DB and code changes? It supposedly creates "backout" scripts
from the DDL that you intend to implement, among other features. I know
some design tools, like Oracle Designer or ERwin, can do many of the same
change management functions.
I recently read an interesting article in STQE magazine ( www.stqemagazine.com <http://www.stqemagazine.com> , May/June 2003 Issue, "Configuration Bugs That Bite") about keeping production and test database versions/schemas synchronized. Pretty interesting- the Oracle DBA created a version table in the database that gets updated anytime structural changes are made (table modifications, etc.). Then, you can easily compare one database version to another, and you can define which version of the DB works with which versions of an application. Also, they described the use of a freeware tool called WinMerge to compare DB schemas. I'm still playing with the idea of the DB version table and creating triggers on all tables that update the version number if any table modifications are made.
