SAP Replication Server Requirements

SAP Replication Sever requirements in capacity planning.

The minimum requirements for each SAP Replication Server include:

One Replication Agent for the Replication Server System Database (RSSD) if there will be a route from this SAP Replication Server.
At least one 20MB raw partition or operating system file for stable queues.
An SAP ASE for the RSSD or an SAP SQL Anywhere data server (SA) for the ERSSD.
An SAP ASE 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
An SAP 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 SAP ASE users. When SAP Replication Server starts, several threads simultaneoulsy attempt to read the RSSD. To accommodate this demand, increase the number of user connections by 20.
Two user connections for each database containing primary data.
One user connection for each replicate-only database.
At least 512MB of RAM for the SAP Replication Server executable program and all the Replication Agents, plus data and stack memory. (RepAgent is an SAP ASE thread; it does not require any SAP Replication Server memory.)
