To delete a minischema, in the Minischemas tab of the Source Navigator, right-click the name of the minischema you want to delete and select Delete.
Deleting a minischema does not delete the data source connection on which the minischema is based.
Note: | When you want to delete a minischema that has user-defined joins, Oracle recommends that you always delete those joins first, then delete the minischema. |
