Adaptive Server Support for Multiple Scanner Threads

The Adaptive Server monitoring tables support multiple scanner threads for RepAgent. Enabling multiple scanner threads for RepAgent provides access to available replication paths and improved replication performance.

Adaptive Server monitoring tables

When you enable multiple scanners, the Adaptive Server monitoring tables provide information about RepAgent scanner task performance. These monitoring table changes have been introduced:

monRepSenders – these columns have been added to provide compatibility with the single-task model.
- NumberOfTruncPointRequested
- NumberOfTruncPointMoved
- AvgTruncPointInterval
monRepScanners –
the NumberOfTruncPointRequested and NumberOfTruncPointMoved columns are populated when the single-task scanning of a log model is used. When the Multi-Path Replication (MPR) model is used, these columns values are 0. The related information for the MPR model can be found on the monRepSenders table.
The monRepCoordinator table has been added.

Any MPR binding model can be used with multiple scanners. For more information about multiple scanner threads, see:

Multiple Scanners in the Replication Server New Features Guide.
