Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: C: New remote configuration base db packages contain fixes and updates that must be loaded into wallaby to take affect. C: Loading a database will replace the contents of wallaby, thus removing any customer changes. C: Created a wallaby shell command that allows upgrading a database. R: Changes from new versions of the remote configuration base db package can be applied to an existing system without destroying customer changes.
Tested on: wallaby-0.12.0-1 What is the option -f (--force) good for? I didn't see any difference when I use it or not.
The database upgrade command uses patches that contain expected values for the entities they are updating, and will only update if the expected value is the same as the current value in the database. For example, if the patch is updating the description on a parameter, then the patch will contain an "expected" value for the parameter's description in addition to the new value. If the value in the database is different than the expected value, the tool will error out. This is because a user is free to change the database as they like, and we aren't going to overwrite their changes without their consent. The -f option will force the upgrade, meaning the tool will ignore differences between the "expected values and the current values in the database and perform the updates.

In that case I think it should also check if there is not the same item as added one. User can accidentally use the same name. E.g. --- before patch 1.15 add CAROD # ccs -l -p CAROD Parameter "CAROD": Name: CAROD Type: string Default: test value Description: test description MustChange: False VisibilityLevel: 0 RequiresRestart: False Dependencies: Conflicts: --- after successful upgrade db without '-f' option # ccs -l -p CAROD Parameter "CAROD": Name: CAROD Type: String Default: $(SBIN)/carod Description: The location of the carod daemon MustChange: False VisibilityLevel: 0 RequiresRestart: True Dependencies: Conflicts:
Agreed the command should check for existing parameters before adding them. Please log a BZ for that.
