Autosys is a popular job scheduling tool used in unix used by several organization to manage job automation for running jobs on time accurately and profficiently. Autosys assists system admis to execute jobs and content of the computer safe, if he or she wished. There are several different things that Autosys is capable of doing.
Autosys is mostly used on the Sun OS, Unix operating system. There are three types of jobs for Autosys. The command jobs execute commands, file watcher job watches for the arrival of a specific file, and the box jobs hold other jobs in a "box". The box jobs can organize and control the flow of processes. Although the box can trigger other jobs to run, the box, itself, performs no actions. developers should also realize some specific details about the box jobs. As long as there is a job in a box that is running, the box will not compelete its action. The box will return a status of either success or failure if one or all of the jobs in the box have succeeded or failed. The box job can run indefinitely unless otherwise specified. There are several different commands for Autosys:
AutoSys: UNIX
Cd to the "autouser" ($AUTOUSER) directory and "." (or source) the "ksh" file. Ex: ". ./autosys.ksh.machine" After installing AutoSys, first make sure that the DB is up and running. Check the installation by running the command chk_auto_up to verify connection to the DB and event processor.
Enter the KEYS through "gatekeeper", add keys
Run the "autosys_secure" command to set the AutoSys Edit and Exec Super users (and also to enter NT users/passwords)
Start the Event Processor by running the command "eventor"
Shutdown AutoSys: "sendevent -E STOP_DEMON"
To start the AutoSys GUI set your DISPLAY and run the command "autosc &".
NT: Start AutoSys from start->programs->AutoSys-> administrator ->Graphical User Interface ->Command Prompt
Command Line Commands:
gatekeeper: Allows you to enter the License Keys which allow you to run AutoSys.
eventor [-M machine_name] : Starts the event processor.
autorep -J [ALL | Job_name] [-q] [> file_name], -d (detail), -r (run number), -o (override), jil < file_na -G (global var report), -M -q for machine definitions.
Ex: autorep -J job_name -d
autorep -J job_name -d
autorep -J job_name -q > file_name queries the DB & save job Dfn. Into a file
vi file_name
When you want a report of a box use the -L0 option
Autorep -J job_name -l1 report on the job for the day -1 (prev day)
sendevent -E STARTJOB -J job_name, sendevent -E FORCE_STARTJOB -J job_name, [JOB_ON_ICE, JOB_OFF_ICE, JOB_ON_HOLD, JOB_OFF_HOLD, SET_GLOBAL, STOP_DEMON. . . .]
sendevent -E STOP_DEMON - to stop AutoSys
(ex: sendevent -E SET_GLOBAL -G "var_name=/home/mydir" to set a var)
(ex: sendevent -E SET_GLOBAL -G "var_name=DELETE" to delete a var)]
chk_auto_up: checks to see if event processor and the DB are both up.
autoping -m machine: verify that both client & server are correctly configured.
cron2jil -f cronfile [-d outdir] [-I incl_file] [-m machine] [-p prefix]
jil <CR>
To insert a job directly into the DB
insert_job: job.id job_type: c
machine: machine_name
command: echo testing jil
[go | ;] (depending on the DB you are using)

autosyslog -e: same as tail -f autosys_log_file. This command must be run from the machine where the server resides if used with the -e option. Else it can be used with the -J option to see that job's run log.
job_depends: -[c|d|t] -J jobname [-F "mm/dd/yy time"] [-T "mm/dd/yy time"] (Note: It will only print out the first occurrence found)
monbro -n monitor_name: Allows you to run from command line monitor/browser programs previously created using the monitor/browser GUI.exec superuser: AUTOSYS superuser
autocal_asc full_cal_name: prints, adds & deletes custom calendar definitions.
autostatus: Reports the current status of a specific job, or the value of an AutoSys global variable. Ex: autostatus -J job_name, -S instance
autotimezone -l : Allows additions, deletions, and queries to the timezones table (-l provides list).
autotrack: Tracks & report changes to the AutoSys DB. Ex: autotrack -l 2 (level 2) [sets the tracking level] autotrack -U sys -v (user sys: verbose) To start using the autotrack utility type: autotrack -u to set tracking level 1 or 2. By default it is set to 0. Autotrack -l will list the current tracking level. Options -[J, U, m, F, T, and t] are to request reporting on a specific Job, User, machine, time window (-F -T), and event type (t). Type is used in conjunction w/other parameters. autotrack w/no arguments retrieves information an all events omitting detail. -v option is for verbose.
autosys_secure: to change edit, exec superusers, change DB passwd, change remote authentication method.
chase [-A|E]: Makes sure that jobs claiming to be running in the client machine are running. The "-E" option restarts the job.
archive_events: to archive events in the DB which are older than x days to prev DB from becoming full.
clean_files: Deletes old remote agent log files. It does it by searching the DB for all machines which have had jobs started on them.
autostatad: to get the status of a PeopleSoft job. You can define one of the user definable buttons to view PeopleSoft job: Autocons*userButton1Label: Adapter Status
User definable buttons: There are user definable buttons in the operator's console.
How to configure:
Autocons*userButton1Command: /autosys/bin/autostatad -J $JOB -g & (which allows you to have a command button on the operator's console.)
Dependencies:
success (job) and s(job_b)
failure(job_a) or f (job_b)
notrunning (job)
terminated(job)
exitcode(job) > 5 and exitcode(job_b) != 10
value(global_name)=100
done(job)
Hostscape: Schedule a job to run every x minutes & then go into forecasting. Make that job fail.
Solid black line: Hostscape can communicate with the remote agent in the client machine.
Solid red line: Hostscape can't communicate with the remote agent but it can communicate with the internet daemon (inetd) running on that machine..
Dashed red line: Hostscape can't communicate with the client machine at all. Client is probably down.
Accessing a variable name: $$GLOBAL_VAR_NAME (unless used in dependency condition with a job definition. If used in the "command" field, you must use the $$)

Creating a Virtual Machine:
insert_machine: virtual
type: v /* default, not required */
machine: real_1
machine: real_2
max_load: 100
factor: 0.5 /* used to describe the relative processing power of a machine. Usually between 0.0-1.0*/
machine: real_2
max_load: 60 /* this is designed to limit the loading of a machine */
Load Balancing, Queuing, priorities:
insert_job: test_load
machine: localhost
command: echo "Test load balancing"
job_load: 50
priority: 1 /* this only affects queues */
Note: For 5.0 we will be using information from ServerVision's towards our load balancer which is composed of 26 categories such as i/o usage, disk usage, CPU usage, etc.
Testing:
zql
zql -U autosys -P autosys
NOTES:
When a job is stuck in the starting condition this means that the event processor communicated with the remote agent and passed all the information the remote agent ran the job but was not able to communicate to the DB. Once testing is done with AutoSys one should change the default refresh interval for AutoSys. This is so there is less querying to the DB. When AutoSys goes from dual mode to single mode, always run the autobcp command before bringing AutoSys back to dual mode/High Availability. Default behavior for stdout is to always appends. If you want to overwrite the file enter the following, no spaces: ">file.out"
Box Logic
Use boxes to group jobs with like scheduling parameters, not as means of grouping jobs organizationally. For example, if you have a number of jobs that run daily at 1:00 a.m., you could put all these jobs in a box and assigning a daily start condition to the box. However, a variety of account processing jobs with diverse starting conditions should not be grouped in the same box.
Default Box Job Behavior
Some important rules to remember about boxes are:
Jobs run only once per box execution.
Jobs in a box will start only if the box itself is running.
As long as any job in a box is running, the box remains in RUNNING state; the box cannot complete until all jobs have run.
By default, a box will return a status of SUCCESS only when all the jobs in the box have run and the status of all the jobs is "success." Default SUCCESS is described in Default Box Success and Box Failure on page 5-13.
By default, a box will return a status of FAILURE only when all jobs in the box have run and the status of one or more of the jobs is "failure." Default FAILURE is described in Default Box Success and Box Failure on page 5-13.
Unless otherwise specified, a box will run indefinitely until it reaches a status of SUCCESS or FAILURE. For a description of how to override this behavior, see Box Job Attributes and Terminators on page 5-6.
Changing the state of a box to INACTIVE (via the sendevent command) changes the state of all the jobs in the box to INACTIVE.
When you Should Not Use a Box
The fact that all jobs in a box change status when a box starts running has lead some to use boxes to implement "job cycle" behavior. Be aware that placing jobs in a box to achieve this end may bring with it undesired behavior due to the nature of boxes.
Avoid the temptation to put jobs in a box as a short cut for performing events (such as ON_ICE or ON_HOLD) on a large number of jobs at once. You will most likely find that the default behavior of boxes inhibits the expected execution of the jobs you placed in the box.
Likewise, you should not place jobs in a box solely because you want to run reports on all of them. When you run autorep on a box, you will get a report on the box and all the jobs in the box (unless you use the -L0 option). In addition, if you use wildcarding when specifying a job name, you could get duplicate entries in your report. For example, suppose you have a box named "acnt_box" containing three jobs named "acnt_job1", "acnt_job2", and "daily_rep". If you specify acnt% as the job name for the autorep report, the report will have an entry for the box "acnt_box" and an entry for each job in the box. Then autorep will continue searching for all job names matching the wildcard characters and, thus, will list "acnt_job1" and "acnt_job2" a second time.
What Happens when a Box Runs
As soon as a box starts running, all the jobs in the box (including sub-boxes) change to status ACTIVATED, meaning they are eligible to run. (Because of this, jobs in boxes do not retain their statuses from previous box cycles.) Then each job is analyzed for additional starting conditions. All jobs with no additional starting conditions are started, without any implied ordering or prioritizing. Jobs with additional starting conditions remain in the ACTIVATED state until those additional dependencies have been met. The box remains in the RUNNING state as long as there are activated or running jobs in the box.
If a box is terminated before a job in it was able to start, the status of that job will change directly from ACTIVATED to INACTIVE.
Note o Jobs in a box cannot start unless the box is running. However, once the job starts running, it will continue to run even if the box is later stopped for some reason.
Time Conditions in a Box
Each job in a box will run only once per box execution. Therefore, you should not define more than one time attribute for any job in a box because the job will only run the first time. If you want to put a job in a box, but you also want it to run more than once, you must assign multiple start time conditions to the box itself, and define no time conditions for the job. Remember also that the box must be running before the job can start. Do not assign a start time for a job in a box if the box will not be running at that time. If you do, the next time the box starts the job will start immediately.
The following example illustrates a scenario that would not work properly if placed in a box.
"job_a" is defined to run repeatedly until it succeeds. "job_report" has one starting condition-the success of "job_a".
How Job Status Changes Affect Box Status
If a box that is not running contains a job that changes status, as a result of a FORCE_STARTJOB or CHANGE_STATUS event, the new job status could change the status of its container box. A change of status of the box could trigger the start of downstream jobs that are dependent on the box.
If a box contained only one job, and the job changed status, the box status would change.
