Replication tuning recommendations are designed to maximize bandwidth between the Relay Server and its Outbound Enablers, Unwired Server, and the EIS connections.
Sybase 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 Unwired
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 Unwired Server. The replication thread count is the
point where Unwired 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.
