Replication Server Requirements

Replication Sever requirements.

The minimum requirements for each Replication Server include:

One Replication Agent for the Replication Server System Database (RSSD) if there will be a route from this Replication Server.
At least one 20MB raw partition or operating system file for stable queues.
An Adaptive Server for the RSSD or a SQL Anywhere data server (SA) for the ERSSD.
An Adaptive Server for the RSSD must have:
- At least 10MB of free device space for the RSSD database directory
- Another 10MB of free device space for the RSSD transaction log directory
A SQL Anywhere data server used as an ERSSD must have:
- At least 5MB of free device space for the ERSSD database directory
- At least 3MB of free device space for the ERSSD transaction log directory
- Another 12MB of free device space for the ERSSD backup directory
20 user connections for the RSSD, in addition to the number of user connections needed by Adaptive Server users. When Replication Server starts, several threads simultaneoulsy attempt to read the RSSD. To accommodate this demand, increase the number of user connections by 20.
One RSSD user connection for each RM and for each RMS in the replication system and one user connection per data server for each RM process and for each RMS process.
Two user connections for each database containing primary data.
One user connection for each replicate-only database.
At least 512MB of RAM for the Replication Server executable program and all the Replication Agents, plus data and stack memory. (RepAgent is an Adaptive Server thread; it does not require any Replication Server memory.)
