How to fix S322 Abend?

When i tried running a job, it gave Abend S322.
It is a time Abend.

First time i ran the job, all the parameters of the job card were given 1 line ( Shown below)

A S322 abend is related to exceeding the amount of CPU time the job or job step can use. If you have no TIME= parameter on the JOB card or the EXEC cards, the system may have a default for the amount of CPU your job can used.

You could run the same job 10 times and you may find the amount of CPU used by the jobs are rarely exactly the same. You may have just exceeded the threshhold with one job and may have been under the threshhold on the other job.

You could code TIME=1440 on the JOB card or the EXEC card to prevent the S322 abend.

Hi,

Could you please let me know what is the significance of giveng "TIME=1440" in the job card or the EXEC ?

What does that 1440 indicate ?

Could you also calerify me the following doubt too ?
So this S322 Abend is no way related to placing the parameters of the job card in one line or in 3 separate lines.

Thanks,
Shan

HI,

Specifing TIME=1440 ensures the job gets unlimitted CPU time and exempted from waiting time.

Hi surya,

good concept got from u.

The S322 abend typically indicates a timeout or job step exceeding the time limit allocated for its execution. Here's a more detailed explanation and steps to resolve it:

Understanding S322 ABEND:

Timeout or Time Limit Exceeded:
The S322 abend occurs when a job step exceeds the maximum CPU time or elapsed time allocated for its execution.

Batch Job Execution:
In a batch processing environment, jobs and job steps are allocated specific time limits to complete their processing tasks.

Job Scheduler Considerations:
Job schedulers, such as JES2 or JES3, enforce these time limits to prevent jobs from monopolizing system resources and to ensure fair resource allocation among multiple jobs.

Causes of S322 ABEND:

Long-Running Job Steps:
The most common cause is a job step taking longer than the allocated time due to extensive processing, large data volumes, or inefficient program logic.

Resource Contention:
Resource contention with other jobs or system activities may also contribute to job steps exceeding their time limits.

Incorrect Job Scheduling:
Incorrect scheduling parameters or insufficient time allocation in job submission can lead to S322 abends.

Steps to Resolve S322 ABEND:

Review Job Step Execution Time:
Analyze the job step's processing logic and data volume to identify areas where execution time can be optimized.

Optimize Program Logic:
Review and optimize the COBOL or program logic to reduce processing time and improve efficiency.

Data Volume Considerations:
If dealing with large data volumes, consider optimizing data access methods, using appropriate indexing, and batch processing techniques.

Resource Management:
Coordinate with system administrators or operators to ensure sufficient system resources (CPU, memory, I/O) are available for job execution.

Job Scheduler Parameters:
Verify and adjust job scheduler parameters, such as time limits (TIME parameter) and priority settings, as needed.

Batch Monitoring and Alerts:
Implement batch job monitoring and alert mechanisms to proactively identify and address jobs nearing their time limits.

Performance Tuning Tools:
Utilize performance tuning tools and utilities provided by the mainframe environment (such as RMF, SMF, or third-party tools) for detailed analysis and optimization.

Testing and Validation:
Test job execution scenarios in a controlled environment to validate changes and ensure that job steps complete within the allocated time.

Do we need any specific user id to run the command TSOCLASS. Its not working for me.

Shefu,

"Jobclass" is the TSO command. I think it should work everywhere.

I feel you are using "CLASS" only. Use TSO JOBCLASS at command prompt.

I tried issuing the command "TSO JOBCLASS" at command prompt
But could see the tso message

IKJ56500I COMMAND JOBCLASS NOT FOUND

hi,

The command JOBCLASS should be Shop Specific.

Hi Sree,

May be this is shop specific.
