Record Locking

Progress supports two types of record locking-shared and exclusive. When working with DataServers, you must be aware that non-Progress database managers implement different record locking procedures. For example:

Progress applications rely on the ORACLE RDBMS to handle all locking for the target ORACLE database. Progress locks do not apply to your ORACLE database.

The DB2/400 database supports NO-LOCK, SHARE-LOCK, and EXCLUSIVE-LOCK when you use the Progress Lock Table on the server. If non-Progress applications are running against the database, do not use the Progress Lock Table and limit your access to NO-LOCK and EXCLUSIVE-LOCK.

See the appropriate Progress DataServer Guide for a comparison of Progress locks to their non-Progress equivalents.
