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