Running SMS

In order for the tasks in a suite to be submitted and thus for the jobs to run there are some things that has to be done.

Page about start-up files.

• SMS must be restarted
• suite must be begun
• task must not be dependent

General

SMS schedules tasks. Tasks are placed into families which in turn may be placed into families and/or suites. All these are called nodes. Nodes ungergo status changes and sometimes flags can be set to indicate various things. Running SMS successfully requires that suites are defined, played into SMS, suite is begun and thet SMS is restarted.

Status of a task

Each task in SMS has got a status. Status is the state in which the node is. In the following the background colour of the text reflects the status colour in XCdp.

The status of a task can vary as follows:

1. After play(CDP) command the tasks are unknown
2. After begin(CDP) command the tasks are either queued, complete, aborted or suspended. Suspened task means that the task really is queued but it must be resumed by user first.
3. Once the dependencies are resolved the task is submitted by SMS. Now the status is submitted or aborted (aborted, if SMSCMD failed.)
4. If the submission was successfull once the job starts it should become active
5. Before the job ends it may send other messages to SMS like

   smsevent	set an event
   smsmeter	change a meter
   smslabel	change a label
   smsmsg	send a message to sms-logfile
   smsmail	send a mail message to user in SMS

6. Job ends by becoming either complete or aborted by job ifself sending the message back to SMS.

7. At any state user can suspend a task which means that it status is saved and a new status given is suspended

So the normal status change for a task is in this picture:

Status of a family or suite

The status of a family or suite is the most significat status of it's kids. While computing the status the real-status is used (that is if node is suspended it's saved status is used.

The status of the SMS itself can also be

• shutdown, if SMS is not scheduling jobs anymore, but allows tasks to communicate.
• halted, if SMS is not scheduling and does not allow tasks to communicate with it. This is the default status when SMS is started and is needed, since recovery is only possible is SMS is halted.

Here is a table of the order of importance of the different statuses and some examples of the result of a status of the family depending on its kids.
