Example 2

Identify the process ID of the java.exe process that corresponds to the IM Configuration Management - View:

Use the procedure below to identify the process ID of the java.exe process that corresponds to the disabled IM Configuration Management - View and then specify that process ID in the jcfthreaddmp command.

If you are running multiple instances of IM Configuration Management - View, there are also multiple java.exe processes. In such a case, you use the procedure described below to identify the process ID.

  1. Add a PID (Process Identifier) column.

    Open Task Manager's Process page, from the View menu choose Select Columns, and then select the PID (Process Identifier) check box in the Select Columns dialog box.

  2. Check whether the relevant IM Configuration Management - View instance is disabled.

    On the Task Manager's Applications page, select IM Configuration Management - View. From the right-click pop-up menu, choose Bring to Front. Check if the IM Configuration Management - View displayed in front is disabled.

  3. Display the PID (process identifier) of the java.exe process that corresponds to the disabled IM Configuration Management - View.

    On the Applications page, select the disabled IM Configuration Management - View, and then from the right-click pop-up menu, choose Go To Process.

    The Processes page is displayed and the java.exe line of the disabled IM Configuration Management - View is selected. The PID column of that line is the process ID of the java.exe process that corresponds to the disabled IM Configuration Management - View.
