Detailed information for the notes.ini Keyword: 


Short Description: Specifies the number of Replicator tasks that can run concurrently on the server.


You can improve server replication performance by running multiple replicator tasks simultaneously. To do this, set the number of replicators by adding this entry in the NOTES.INI file, where the value is the number of replicators.

A replicator task synchronizes a source database with its replicas. Starting more than one replicator allows a server to replicate its databases with more than one server simultaneously. If, however, you enable two replicators, and the server only needs to replicate with one other server, then only one replicator is used. The other task remains idle. Multiple replicators will speed up synchronization but may increase workload significantly on the server.

All other factors aside, it is recommend that you set the number of replicator tasks equal to the number of spoke servers with which the hub replicates. However, you should not exceed 20 replicators to avoid putting too much load on the server. If the server you intended to replicate is not a hub server, the recommended number of replicators should equal the number of processors on the server.


Replicators = number of processors -1

You must shut down and restart the server for this setting to take effect.

Default value:



UI equivalent:
