Check the Processes

A stopped or stalled process might make your system inactive. Check your system processes by:

• Restarting Line Scrolling
• Using the Ctrl-D Key Sequence
• Using the Ctrl-C Key Sequence
• Logging In from a Remote Terminal or Host
• Ending Stalled Processes Remotely

Restarting Line Scrolling

Restart line scrolling halted by the Ctrl-S key sequence by doing the following:

1. Activate the window or shell with the problem process.
2. Press the Ctrl-Q key sequence to restart scrolling.

The Ctrl-S key sequence stops line scrolling and the Ctrl-Q key sequence restarts scrolling.

Is your system now active?

Using the Ctrl-D Key Sequence

End a stopped process by doing the following:

1. Activate the window or shell with the problem process.
2. Press the Ctrl-D key sequence. The Ctrl-D key sequence sends an end of file (EOF) to the process. The Ctrl-D key sequence may close the window or shell and log you out.

Using the Ctrl-C Key Sequence

End a stopped process by doing the following:

1. Activate the window or shell with the problem process.
2. Press the Ctrl-C key sequence. The Ctrl-C key sequence stops the current search or filter.

Logging In from a Remote Terminal or Host

Log in remotely in either of two ways:

• Log in to the system from another terminal if more than one terminal is attached to your system.
• Log in from another host on the network (if your system is connected to a network) by entering the following tn command:

  tn YourSystemName

  The system asks for your regular login name and password when you use the tn command.

Were you able to log in to the system from another terminal or host?

Ending Stalled Processes Remotely

End a stalled process from a remote terminal by doing the following:

1. List active processes by entering the following ps command:

   ps -ef

   The -e and -f flags identify all active and inactive processes.
2. Identify the process ID of the stalled process.

   For help identifying processes, you can use the grep command with a search string. For example, to quit the xlock process, enter the following to find the process ID:

   ps -ef | grep xlock

   The grep command allows you to search on the output from the ps command to identify the process ID of a specific process.
3. End the process by entering the following kill command:

   Note: You must have root user authority to use the kill command on processes you did not initiate.

   kill -9 ProcessID

   If you cannot identify the problem process, the most recently activated process might be the cause of your inactive system. End the most recent process if you think that is the problem.
