GOAL:

Can schema changes be made in multi-user mode?

GOAL:

What changes can be made to a database while running in multi-user mode?

FACT(s) (Environment):

Progress 9.1x
All Supported Operating Systems
OpenEdge Category: Database

FIX:

IMPORTANT NOTE: Always backup the database and verify the backup before performing any schema changing tasks.

The following actions may be performed in multi user mode (online):

1. PROUTIL tablemove and indexmove albeit at a significant performance cost.

2. Adding and deleting tables and fields provided that no other user is using the database. Only one user can update any part of the schema at a given time.

3. Using the Data Dictionary, the Data Definition files (.df) may also be dumped and loaded.
