This section is for advanced users or those who prefer a command line interface (CLI) to manage jobs.
All zos commands begin with zos on the command line. The general format for a zos command is zos followed by the command name, followed by command line parameters, if needed:
zos command [command_parameters]
Before you use the zos CLI, make sure that your path is correctly pointing to the Orchestration Server tools directory. On Windows platforms, the path is automatically set when you launch the Orchestration command prompt window. If the path is set, you then need to log in to the Orchestration Server before the commands work.
This section includes the following information:
The administrator for the Orchestration Server provides a username, a password, and the name for the Orchestration Server. The following shows a sample login sequence. Italics are used to indicate variable names.
>zos login -user=username Orchestration_server_name Please enter current password for 'Orchestration_server_name': ******* Logged into Orchestration_server_name_zos> as username
The login should now be complete.
Login information is stored in the home directory, so further zos commands on this server use the saved login information. To operate on a different Orchestration Server, run zos login again with the new server information.
Use the run command to start a job. For example, if you want to run the “quickie” job, you would enter the following command:
>zos run quickie
If the job submission was successful, a JobID is displayed:
To specify parameters when you start a job, add the parameters to the command line. For example, if you wanted to run the quickie job, specifying the numJoblets parameter with a value of 100, you would enter the following command:
>zos run quickie numJoblets=100 JobID: tester.2.quickie
The Orchestration Server keeps track of your last started job so that further zos commands can default to the last started job. To operate on a different job, specify the Job ID as a command line parameter.
A job can be monitored or managed when it is started or after it is started. To view the status of the last started job, use the status command:
>zos status Running
The server returns the status immediately. In the preceding example, the job is Running, which means the job is still being processed. Possible status messages include the following:
You can retrieve detailed status information about a job by using the -e option in the command line, as shown in the following example for the last started job:
>zos status -e Job Status for tester.quickie.2 ----------------------------- State: Running (waiting for resources) Resource Count: 0 (0 this job) Percent Complete: 1% Queue Pos: n/a Child Job Count: 0 (0 this job) Instance Name: quickie Job Type: quickie Memo: Priority: medium Arguments: numJoblets=100 Submit Time: 5/01/2012 12:20:19 Delayed Start: n/a Start Time: 5/01/2012 12:20:19 End Time: n/a (estimated) Elapsed Time: 0:00:05 Queue Time: 0:00:00 Pause Time: 0:00:00 Total CPU Time: 0:00:00 (0:00:00 this job) Total GCycles: 0:00:00 (0:00:00 this job) Total Cost: $0.0000 ($0.0000 this job) Burn Rate: $0.0000/hr ($0.0000/hr this job) Cancel Type: <none> Job Error: <none> Job Error Count: 0 (0 this job) Joblet Retry Count: 0 (0 this job) Node Error Count: 0 (0 this job)
