Summary
This function returns a replica database configuration. Use the output of
this function in the
admin.databaseSetForeignReplicas
function to place the replica database configuration into the cluster
configuration.
Parameters |
foreign-cluster-id |
The ID of the foreign cluster containing the replica database.
|
foreign-database-id |
The ID of the replica database.
|
connect-forests-by-name |
Boolean that indicates whether to connect to forests by name. If
fn:true , forests will automatically connect to/from foreign
forests of the same name. If false , forests must be
individually
configured to replicate to/from foreign forests. Individual forest settings
override the database level setting.
|
lag-limit |
This parameter controls how far (in seconds) the replica may fall
behind before the master stops accepting updates.
If contact with the foreign cluster is lost, a warning will be logged and
master forests will permit updates to proceed with no enforcement of the
lag limit.
|
replication-enabled |
This parameter controls if replication is enabled. Set to true
to enable, false to disable.
|
queue-size |
This parameter specifies the number of frames in the queue for foreign
replication, or the number of fragments if you are doing bulk replication.
The default is 10.

Example
const admin = require('/MarkLogic/admin.xqy');
const fdb = 7746794057802787479
const cfg = admin.getConfiguration()
const fcl = admin.clusterGetForeignClusterId(cfg, "ClusterA")
admin.databaseForeignReplica(fcl, fdb, fn.true(), 300)
//Returns the replica database configuration. Use the
//admin.databaseSetForeignReplicas function to set the confirguration.
