Home -> Community -> Mailing Lists -> Oracle-L -> RE: Database Comparison
I've had some problems with the Change Manager.
For some databases it doesn't "see" any of the objects that would fall in the last few item categories in the navigator pane on the left - including tablespaces.
There is a bug with the JVM, sometimes the Oracle Java tool colours go beserk (fluorescent) and in one occation the window positioning was completely off. I use 1024x768 desktops on some NT servers. Sometimes the whole graphic column that shows checkmarks or crosses in comparison reports appears in the upper left corner of the screen instead of where it should be. These are probably all related to the same "known bug" for the JVM display functions.
The reports also are extensive, I don't know if it is possible to tell Change Manager to only put in reports just the information you want. Internet browsers are not happy with HTML files that are megabytes in size, they take a long time to load.
The Change Manager is faster if run on the console holding the repository than from a remote client. I recommend running it from the OEM repository console if at all possible, to avoid network trips as the Change Manager stores information into the repository. There will be enough networking going on with it comparing two remote systems.
Would anyone care to share tips on how to use Change Manager appropriately? Did you find any problems with Change Manager, are there any differences it did not catch?

Srini,
Use the change manager that comes with Oracle Enterprise manager. The
initial set-up is little bit difficult. But once u r through, then it is an
handy tool.
