Monitoring the Queue Loading and OverflowLocate this document in the navigation structure

Use

You can monitor the queue loading and overflow through the Queue Overflow and Long Running functions within the Threads pane.

Prerequisites

You have started SAP NetWeaver Administrator and use the System Overview application.

Procedure

Viewing the Queue Overflow

This function allows you to view the number of blocked threads waiting to submit a task in the queue of waiting tasks.

  1. The red traffic light of Queue Overflow indicates that there are no free threads to process.

  2. As a result, the size of the waiting task's queue is full and the threads that need to submit a new task in this queue block wait until a free slot is available.

  3. To resolve the problem with the queue overflow, choose Manage Sessions from the context menu of the function and go to the Session Management application in SAP NetWeaver Administrator.

Administering Long Running Threads

The Long Running function allows you to view the total number of long running threads on all server processes (nodes) of a certain system.

  1. If there are one or more long running threads, the traffic light is red.

  2. To view the long running threads, choose Manage Sessions from the context menu of the function and go to Session Management in SAP NetWeaver Administrator.

  3. Determine the session that has caused the problem and choose Terminate .
