Each Replication Agent for Oracle, Replication Agent for Microsoft SQL Server, and Replication Agent for IBM DB2 UDB instance use an embedded SQL Anywhere® database to manage its Replication Agent System Database (RASD).
Because the RASD stores information about primary database structure or schema objects, its size depends partly on the number of replicated tables and procedures and the number of database users in the primary database.
When it replicates a data definition language (DDL) transaction, the Replication Agent creates a new version of the affected object’s metadata in its RASD. Over time, the size of the RASD can grow significantly, depending on the number and frequency of DDL transactions replicated.
If the RASD runs out of disk space, the Replication Agent shuts down and suspends replication. To prevent this, provide adequate disk space on the Replication Agent host machine to accommodate the initial size of the RASD, as well as some potential growth.
