Shutting Down

This section describes how to shut down CA XCOM Data Transport for Linux s390x before performing an upgrade or a reinstall.

Note:

You must log on as a superuser (root), or as a member of the xcomadm group, to perform this procedure.
The CA XCOM Data Transport daemon must still be running to execute the command in Step 1.

Important! The command in Step 1 removes all active transfer entries.

Follow these steps:

At the command line, enter the following command:
```
xcomqm -Rf*	
```
All queue entries are deleted.
If xcomtool is active, then it must be closed. To close xcomtool, click in the Main window and select Quit from the menu bar. .
Enter the following command:
```
xcomd -s
```
CA XCOM Data Transport shuts down, and the following messages are displayed:
```
XCOMU0079I xcomd: stop requested.
```
```
XCOMU0082I xcomd: stop request accepted.
```
Note: If you are working from the console, a message similar to the following also displays:
```
