Cluster_Replicators

Parameter: Cluster_Replicators
Short description: Starts multiple cluster replicator tasks in parallel on a Domino cluster server.

Profile

Parameter
Cluster_Replicators
Category
Cluster
Available since
At least 11.0.1 (HCL documentation)
GUI equivalent
According to HCL, no direct GUI option. Can be set in the Configuration document on the NOTES.INI Settings tab.
Possible values
Integer — number of cluster replicator tasks running in parallel
Default
None — according to HCL documentation, Domino starts exactly one cluster replicator if not set.

Description

According to the HCL product documentation:
Use this setting to start multiple cluster replicators, where value is the number of cluster replicators required.
Without the parameter, exactly one cluster replicator task runs. With Cluster_Replicators=N, N cluster replicator tasks are started in parallel — useful on cluster servers with many replicas or high write load, because replications to different cluster mates can then be processed simultaneously.
Important: Cluster_Replicators exclusively affects cluster replication (real-time replication between cluster mates). For scheduled / standard replication, Replicators is responsible.

Example configuration

Cluster_Replicators=3
With Cluster_Replicators=3, the server starts three cluster replicator tasks in parallel. HCL does not pin down a specific sensible value in the product documentation — it depends on hardware, number of cluster mates, and replica load.

Notes & pitfalls

  • Not to be confused with Replicators (controls the normal replicator tasks) and Disable_Cluster_Replicator (turns cluster replication completely off/on).
  • According to HCL there is no direct GUI equivalent; the value can be maintained via the NOTES.INI Settings tab of a Configuration document.
  • Too many parallel cluster replicator tasks can put load on CPU/IO without providing additional benefit — increase gradually and monitor server statistics.
