You can only run one before-image writer (BIW) per database. You can start and stop the BIW process at any time without shutting down the database.

To start the BIW process, use OpenEdge Management or enter the following command on the local machine:

probiw db-name

The BIW counts as a process connected to a database and uses resources associated with a user. You might have to increase the value of the Number of Users (-n) parameter to allow for the BIW. However, the BIW is not counted as a licensed user.

Stop the BIW by disconnecting the process with the PROSHUT command.
