Automatic Memory Management with SAP Replication Server 16.0 SP03 PL04

In SAP Replication Server releases prior to 16.0 SP03 PL04, the replication involving multiple databases was resource intensive and complex. With automatic memory management enhanced in 16.0 SP03 PL04, SAP Replication Server supports you to replicate multiple databases (certificated with 20) in parallel with the simpler configuration steps and lower total cost of ownership (TCO). Thus, with this feature enabled, SAP Replication Server performs much better when you manage multiple pairs of databases in the HADR and non-HADR environments.

It has quite a number of enhancements within SAP Replication Server, but all you have to do is just to be aware that this feature is coming and is enabled by default for you. And that’s it!

Amazing? That’s not all. The other good news is that, with this feature enabled, you don’t have to configure the following configuration parameters by yourself anymore. SAP Replication Server dynamically adjusts the memory resources among different components.

Component Parameter
Component Interface (CI) ci_pool_size
Capture cap_sqm_write_request_limit
Stable Queue Manager (SQM) sqm_cache_size
Stable Queue Transaction (SQT) sqt_max_cache_size
Simple Persistent Queue (SPQ) spq_cache_size
Data Server Interface (DSI) dsi_sqt_max_cache_size
Distributor (DIST) dist_sqt_max_cache_size
