On the "Versioned Patches" tab select "Local" from the "Version Control" drop down.
(This means Lure will keep a local history of table changes as opposed to depending on a version control system.)
Enter a patch test schema and password. This schema will be used for testing table patches and therefore has to have a CREATE TABLE privilege.
In addition the schema also needs EXECUTE privilege on SYS.DBMS_LOCK, and appropriate tablespace privileges.
