Replication tuning recommendations are designed to maximize bandwidth between the Relay Server and its Outbound Enablers, SAP Mobile Server, and the EIS connections.
SAP recommendations touch on components outside and inside the LAN:
- For large replication payloads greater than 4MB, increase the bandwidth between
the Relay Server and the SAP Mobile Platform cluster nodes by
increasing the number of Relay Server Outbound Enablers (RSOEs) and increasing
the shared memory of the relay servers.
- Ensure adequate processing bandwidth for peak conditions by setting an adequate replication thread count for the entire cluster (the
combination of each node’s replication thread count) and JVM memory settings you configure for SAP Mobile Server. The replication thread count is the
point where SAP Mobile Server and cache database (CDB) throttling, or limiting, occurs.
The speed of the CDB storage and storage controllers is the single most important factor
in providing good system performance. Staging of mobile data is performed within the CDB in a persistent manner
such that if a device synchronizes. The CDB database server itself is largely self-tuning, although typical database
maintenance is essential for proper performance.
- Provide
as many resources as are available as you work back to the EIS. Do not limit connection pools.
