A method and apparatus for concurrently updating a database is provided. An exclusive copy of a record is created in the database, the exclusive copy for exclusive use by a first entity of a first class. First proposed changes to the record from the first entity are posted to the exclusive copy. It is determined if the exclusive copy conflicts with a non-exclusive copy of the record, the non-exclusive copy for non-exclusive use by a plurality of second entities of a second class. If the exclusive copy does not conflict with the non-exclusive copy, the first proposed changes are posted to the record. Hence high availability devices can concurrently modify the database in parallel with low availability configuration applications, with conflict resolution.
