NEW QUESTION # 183
A developer creates a batch Apex job to update a large number of records, and receives reports of the job timing out and not completing.
What is the first step towards troubleshooting the issue?
Answer: D
Explanation:
When a batch Apex job is timing out and not completing, the first step in troubleshooting is to check the job's status and logs in the Asynchronous Job Monitoring page. This page provides information about all asynchronous Apex jobs, including batch Apex, scheduled Apex, future methods, and queueable Apex.
Option D: Check the asynchronous job monitoring page to view the job status and logs.
Correct Approach.
The Asynchronous Job Monitoring page (also known as the Apex Jobs page) in Salesforce Setup allows developers to see the status of all asynchronous Apex jobs.
By checking this page, the developer can see whether the batch job is still running, failed, or completed.
If the job has failed, the page provides error messages that can help identify the cause of the failure.
This is the first step to determine what is happening with the batch job.
While checking the debug logs can provide detailed information, it is more efficient to first check the job status on the asynchronous job monitoring page.
Debug logs can be large and may not be generated if the job did not execute properly.
After identifying the job's status and any error messages, the developer can then decide if checking debug logs is necessary.
Option C: Decrease the batch size to reduce the load on the system.
Possible Solution, Not First Step.
Decreasing the batch size may help prevent timeouts by processing fewer records at a time.
However, before making changes to the batch job, the developer should first investigate the cause of the timeout.
Option A: Disable the batch job and recreate it with a smaller number of records.
Not Recommended as First Step.
Disabling and recreating the batch job without understanding the issue may not resolve the problem.
It's important to diagnose the issue before making changes.
Conclusion:
The first step towards troubleshooting a batch Apex job that is timing out is to check the asynchronous job monitoring page to view the job's status and any error messages.
This provides immediate insight into what is happening with the job and guides the next steps in troubleshooting.
Reference:

Apex Jobs Page
Option B: Check the debug logs for the batch job.
Next Step, Not First Step.
