Logging QoS server jobs

 

When you encounter problems with your quality of service (QoS) policies, analyze the job logs. The job log contains error messages and other information related to QoS.

Only one QoS job, QTOQSRVR, runs in the subsystem QSYSWRK. You can see the old and current QoS server job logs from iSeries™ Navigator.

To see the log, follow these steps:

  1. Expand Network and click IP Policies.

  2. Right-click Quality of Service.

  3. Click Diagnostic tools > QoS Server Log.

This opens a window that allows you to work with the job.

The following list shows the most important job names, along with a brief explanation of what the job is used for:

QTCP

This job is the base job that starts all the TCP/IP interfaces. If you have fundamental problems with TCP/IP in general, analyze the QTCPIP job log.

QTOQSRVR

This job is the base QoS job that gives you log information specific to QoS. Run the Work with Spooled File command (WRKSPLF QTCP) and look for the QTOQSRVR log.
