Installation and Upgrade
Once the Service Locator feature configured to work in your Talend Runtime container(s), you can install and run it.

Procedure

  1. Start the container:
    • container/bin/trun.bat for Windows,

    • container/bin/trun for Linux.

    New files appear in the container/etc directory.
  2. If you need to configure the Service Locator server, edit the configuration file named: org.talend.esb.locator.server.cfg.
    The parameters available are the following:
    tickTime=2000
    initLimit=10
    syncLimit=5
    dataDir=${karaf.base}/zookeeper/data
    clientPort=2181
    maxClientCnxns = 0
    authentication = false
    Here is a description for each of the fields:

    Field name

    Description

    tickTime The basic time unit in milliseconds used by the Service Locator. It is used to do heartbeats, and the minimum session timeout will be twice the tickTime.
    initLimit The number of ticks that the initial synchronization phase can take.
    syncLimit The number of ticks that can pass between sending a request and getting an acknowledgment.
    dataDir The location to store the in-memory database snapshots and, unless specified otherwise, the transaction log of updates to the database.
    clientPort The port to listen for client connections.
    maxClientCnxns Number of client connection. Default is 10. 0 is unlimited.
    authentication To enable the authentication in the Service Locator server.
  3. Now that you have configured the Service Locator, you can start it in the Talend Runtime Container. To do so, execute the following command at the console prompt: tesb:start-locator
  4. To check that the service has been successfully started and is active, execute the console command: list | grep Locator
    You should see an output similar to this:
    ID      State     Blueprint  Spring   Level  Name
    [ 211] [Active ] [Created ] [      ] [ 80]   Talend ESB :: Locator :: Server ()

    To ensure that the feature is installed successfully, you can try examples that use the Service Locator server.

    To uninstall and stop the Service Locator, execute the console command:

    tesb:stop-locator
