4.7.4. Creating the Linux Job Scheduler Remote Host

To configure a link to your Linux cluster, you create a host in Analyst-MP:

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

  2. The Job Scheduler Admin dialog box appears.

  3. Click the Create a new host entry button to create a new host entry. The Host Details will appear.

  4. For Entry Name enter a user-friendly name for this host. This does not need to match the name of the remote computer or anything else. For Initialization > Transport choose awr_ssh_ipc. This tells the job scheduler that you want to use a secure shell connection (SSH) to communicate with the remote cluster.

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

  6. For Initialization > SSH Authentication > User Name enter your user account name on your cluster. For privatekey click the ellipses button 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 “Configure SSH”); do not use a private key created by means of a third-party tool. Enter the passphase if you used one when creating the keys.

  7. Set your cluster resource mangager type in Initialization > Cluster Resource Manager > Type. If your cluster has more than one queue, enter it's name in Initialization > Cluster Resource Manager > Queue Name, otherwise leave this empty.

  8. If the Linux cluster has to be accessed through a remotehost or gateway, enter that IP address or host name in Initialization > Optional SSH Forwarding (Tunneling) > Destination Host. Otherwise, leave this empty. Change the Destination Port and Source Port, if different from the defaults.

  9. Click the Verify button on the Host Details dialog box. The system will try 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”.

  10. 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.

  11. 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.

  12. 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.
