With Adaptive
Server 15.7 SP100, you can enable multiple scanner threads for Adaptive Server RepAgent to
take advantage of all available replication paths and improve replication
performance.
Multiple scanner threads dedicated to each path allow all
the scanner threads to scan the database log and generate LTL commands in parallel, and:
- Increase throughput by reducing the time that the sender thread
waits for LTL commands from the scanner thread.
- Reduce memory consumption because each scanner generates only the
LTL commands that the respective path requires.
Note: You must enable multiple scanners before you configure RepAgent to use the
distribution by filter model of multipath replication.
