These commands and options are described below:
Table 9.33. replicator Commands Options for condrestart
| Option | Description |
|---|---|
offline | Start in OFFLINE state |
Restart the replicator, only if it is already running. This can be useful to use when changing configuration or performing database management within automated scripts, as the replicator will be only be restart if it was previously running.
For example, if the replicator is running, replicator condrestart operates as replicator restart:
shell> replicator condrestart
Stopping Tungsten Replicator Service...
Waiting for Tungsten Replicator Service to exit...
Stopped Tungsten Replicator Service.
Starting Tungsten Replicator Service...
Waiting for Tungsten Replicator Service......
running: PID:26646However, if not already running, the operation does nothing:
shell> replicator condrestart
Stopping Tungsten Replicator Service...
Tungsten Replicator Service was not running.− console
Launch in the current console (instead of a daemon)
− dump
Request a Java thread dump (if replicator is running)
− install
Installs the startup scripts for running the replicator at boot. For an alternative method of deploying these start-up scripts, see deployall.
− remove
Removes the startup scripts for running the replicator at boot. For an alternative method of removing these start-up scripts, see undeployall.
− restart
Table 9.35. replicator Commands Options for restart
| Option | Description |
|---|---|
offline | Stop and restart in OFFLINE state |
Restarting a running replicator temporarily stops and restarts replication.
Stops the replicator, if it is already running, and then restarts it:
shell> replicator restart
Stopping Tungsten Replicator Service...
Stopped Tungsten Replicator Service.
Starting Tungsten Replicator Service...
Waiting for Tungsten Replicator Service......
running: PID:26248− start
To start the replicator service if it is not already running:
shell> replicator start
Starting Tungsten Replicator Service...− status
Checks the execution status of the replicator:
shell> replicator status
Tungsten Replicator Service is running: PID:27015, Wrapper:STARTED, Java:STARTEDIf the replicator is not running:
shell> replicator status
Tungsten Replicator Service is not running.This only provides the execution state of the replicator, not the actual state of replication. To get detailed information on the status of replication use trepctl status.
− stop
Stops the replicator if it is already running:
shell> replicator stop
Stopping Tungsten Replicator Service...
Waiting for Tungsten Replicator Service to exit...
Stopped Tungsten Replicator Service.
If the cluster was configured with
auto-enable=false then you will need to put
each node online individually.
