4.6.3. Creating the Linux Job Scheduler Remote Host

To configure a link to your Linux cluster:

  1. From the Home in the Settings group, choose Job Scheduler Admin from the Environment drop-down menu:

  2. The Job Scheduler Admin dialog box appears. On the General Settings tab of the dialog box, click the Create a new host entry button to create a new host entry. Note that the initial entry in the Verified column for your new host entity is "Not Verified".

  3. Click the line for the host entry, then click the Edit host entry details button to display the Host Details dialog box.

  4. For Entry Name enter a name for your host. From the transport drop-down menu choose awr_ssh_ipc.

  5. For Initialization > host enter the IP address, or hostname of the master node on your cluster:

  6. For Initialization > authentication > username enter the user account name on your cluster. For privatekey click the ellipses on the right margin of the dialog box. Navigate to the location where the private key matching the public key on your cluster is stored, and click Open on the Browse dialog box to choose the key. This should be the Linux private key you created (see “Configuring SSH”); do not use a private key created by means of a third-party tool.

    If the Linux cluster has to be accessed through a remotehost/gateway, enter the ipaddress or remotehost name in Initialization > tunnel > remotehost. Otherwise, leave remotehost empty. Change the remoteport and forwarding port, if different from the defaults.

  7. Click the Verify button on the Host Details dialog box. Analyst tries to verify that a communication link can be established with your cluster. On success, a message box is displayed showing the message "Host Verification Succeeded!".

    On failure, a message box is displayed showing the message "Host Verification FAILED!" and the error causing the failure.

    For a discussion of steps to take to troubleshoot a verification failure, see “Troubleshooting Host Verification”.

  8. Click the OK button to close the message box, then click the OK button close the Host Details dialog box. If the verification succeeded, a green check mark and the word "Verified" is displayed in the Job Scheduler Admin dialog box Verified column for the new host entry. The verification process for this host is now complete, you do not need to perform verification again the next time you run a simulation on this host.

  9. If you have additional hosts on which you would like to run remote simulations, add them using the method above. When you have finished adding all of your hosts, make sure the box next to each host's name in the Entry Name column is checked to enable the host. If you prefer to disable the host and make it unavailable for use while storing its values in the system, clear the box.

  10. Click the Save button on the Job Scheduler Admin dialog box to save the settings for your host entries, and then click the Done button in the lower left corner to close the dialog box.

  11. After you have added and verified your host(s), restart Analyst to load the host definition(s) into the system.
