Release 10.1A: OpenEdge Data Management:
Database Administration

PROBIW command

Starts a before-image writer (BIW) process.

Syntax

probiw db-name

Parameters

db-name

Specifies the database where you want to start a BIW.

The BIW improves database performance by performing before-image overhead operations in the background. For more information on the BIW, see Chapter 13, " Managing Performance."

Notes

To stop the BIW process, disconnect it by using the PROSHUT command. You can start and stop the BIW at any time without shutting down the database.
The BIW process counts as one user. You might have to increment the value of the Number of Users (-n) parameter to allow for the BIW. However, the BIW does not count as a licensed user.
You can increase the number of before-image buffers with the Before-image Buffers (-bibufs) parameter. Increasing the number of buffers increases the availability of empty buffers to client and server processes.
Before-image writers are only available on Enterprise systems.
