Effective troubleshooting of critical issues in Oracle E-Business Suite (EBS) is essential for maintaining business continuity. Leveraging diagnostic tools provided by Oracle Support can significantly reduce downtime and expedite resolution. We recently encountered a situation that underscores the importance of using these tools to address system-wide issues swiftly and efficiently.
Issue Encountered
Last week, we faced a widespread issue within Oracle E-Business Suite R12.2 where users were unable to view the output of concurrent programs. When selecting the "View Output" button, the system consistently displayed a blank page instead of the expected report output. The issue affected all users across the environment. Despite reviewing the available logs in detail, no actionable information could be gathered, prompting us to raise a Service Request (SR) with Oracle Support.
Diagnosis and Resolution via Oracle SR
During the diagnostic process, we discovered a built-in tool within EBS R12.2 named "FS Diagnostic Test Program." This utility proved invaluable in identifying the root cause of the issue.
The FS Diagnostic Test Program is designed to simulate file transfer operations typically handled by concurrent processing components such as FNDFS and FNDWRR.exe. It includes logic to generate diagnostic logs, facilitating easier debugging of issues related to output and log file delivery.
The program can be executed in various modes, controlled by the Mode parameter:
-
FULL – Executes all available tests (default)
-
FILE – Tests file copy operations
-
REQLOG – Verifies access to concurrent request log files
-
REQOUT – Verifies access to concurrent request output files
-
MGR – Tests viewing concurrent manager log files
-
RFILE – Tests remote file copying
We ran the diagnostic test using the appropriate modes and uploaded the results to the open Oracle SR. Based on the diagnostic output, Oracle Support was able to quickly analyze the issue and provide an effective solution.
Key Takeaway
This experience reinforced the value of leveraging built-in diagnostics to accelerate support resolution. Oracle Support can offer faster, more targeted assistance when provided with relevant diagnostic outputs upfront. We highly recommend incorporating tools like the FS Diagnostic Test Program into your standard troubleshooting toolkit when working with Oracle E-Business Suite R12.2.
