Duplicate database and active duplicate database in 11g is becoming more common as a means of cloning an Oracle database. However I have been thinking about how that affects patch levels and the inventory.
A patch can have 3 effects
1) Modify a binary 2) Modify the data dictionary 3) Both
If a db duplicate script is run then a db containing a patch of type 1or 3 will be potentially out of sync if it has moved to a new Oracle home The opatch lsinventory output from each binary would be different where a change of type 2 had been applied and yet the databases and binaries would be identical.
I know the answer is to have documented procedures which define the patch levels run against every installation but I am wondering how other people are managing this issue.
