Managing SessionsLocate this document in the navigation structure

Use

Using Session Management , you can monitor and administer all open user sessions in AS Java. All sessions are aggregated. You can perform the following activities:

  • monitor who is working on the system and what applications they are using

  • start tracing particular sessions

  • terminate cluster/user sessions

  • activate filters and then view the result in other related tools

Prerequisites

To start the function, open SAP NetWeaver Administrator and navigate to Start of the navigation path  Configuration  Next navigation step  Infrastructure  Next navigation step  Session Management  End of the navigation path.

Alternatively, you can access the function with the quick link: /nwa/sessionmgt .

Procedure

Monitoring Sessions

In the User Sessions area, you get a list of all user sessions on AS Java (for example, Administrator, Guest, other user).

In the table, you can view various parameters of a user session:

  • Last Accessed Time - shows the time when a user has last accessed the session.

  • Total Number of Requests - represents the sum of the requests of all its cluster sessions.

  • Total Active Requests - shows the sum of all active requests in the cluster sessions. If no cluster session is active - the number for the relevant user session is 0 (zero).

  • Longest Active Request - shows the active/inactive requests and their duration (in milliseconds).

  • Longest Response Time - shows the maximum response time among all cluster sessions.

  • Overall CPU Usage , Overall DB Time , Allocated Memory - analogically as Longest Response Time .

  • Trace Options - shows the options you have chosen when start tracing. For more information, see the " Tracing Sessions " procedure below.

  • Profile Result - provides a ZIP file you can download to see the results from the last tracing.

Administering Sessions

  • To terminate a session, select it and choose Terminate .

    If you select a session from Individual Sessions , only it will be stopped. If you select a user session, all its individual sessions will be stopped.

  • To terminate a certain application, select it and choose Terminate .

  • To update the list of sessions or applications, choose the relevant Refresh buttons.

  • To download all the table data into a spreadsheet application, choose Export to Spreadsheet .

  • If you set filters, you have a direct connection to other tools where you can view logs or perform tasks concerning these particular filters. To do that, choose Related Links .

    Example

    1. Select a session with ID = <Session_Number> .

    2. Choose Start of the navigation path Related Links  Next navigation step View Session Logs End of the navigation path. The Log Viewer tool is opened.

    3. Choose Show Advanced Filter . The Passport HTTP Session filter is set with filter value = <Session_Number> .

    4. In the table, you can see all logs and traces relevant for the selected session.

Tracing Sessions

  1. Select the particular session and choose Start Trace . A dialog box appears.

  2. From Trace Options , select the tracing methods you need.

    Note

    You can have only one of the JVM Profiler - Memory Analysis and the JVM Profiler - CPU Analysis options selected at the same time.

  3. Choose OK .

  4. In the Trace Options column of the table, you can see the methods you have selected.

Caution

Only one tracing process is allowed to be running at a time. That is, If you start another one (from another browser or user), a message appears warning you that the current trace will be stopped.

Advanced Searching

  1. To search for a particular session, choose Show Advanced Search .

    You can use the following options:

    • Application Name - you can enter only part of the application name string.

    • Session ID - you need to enter the whole ID number, since each session is unique.

    • Action - you can enter only part of the action name string.

  2. Choose Go .

  3. To clear the current search criteria, choose Clear .
