n
The number of Kb to allocate as the size of the database service communication area.

The database service communication area stores after-image block write notifications intended for OpenEdge Replication. The -pica parameter lets a DBA increase the size of the database service communication area queue, to prevent client stalling in heavy load situations, without the need to restart database brokers or replication.

Check the Database Service Manager in the PROMON utility to monitor pica queue growth. Increase the pica queue size when the Free Message Entries value is 0 or the Area Filled Count is greater than 0.

AI streaming in a replication agent reduces the need for a large pica queue.

To modify this parameter while the database is online, use PROUTIL INCREASETO.

You can use this parameter to support continuous operation of the database. For more information, see Change database parameters while the database is running.
