Stopping SCS or NonStop ODBC Server Processes
The SQL Communication Subsystem is now ready to accept connections from clients.
Proceed to Installing the Client on the PC on page 2-27 to see how to configure and
start your clients.
If you have any difficulty, see Troubleshooting on page 2-58.
Stopping SCS or NonStop ODBC Server Processes
To stop an SCS process, enter:
STOP SCS scs-name [NOWAIT]
The NOWAIT parameter specifies that the SCS process is to stop immediately. Without
that parameter, the SCS process continues with its current sessions, but on dynamic
configuration boundaries, it stops accepting new login requests and shuts down each
NonStop ODBC server process as it completes its current user session.
You can also stop NonStop ODBC server processes by using the TACL command
STOP. You might want to do this if the processes are not responding or are processing
a very large SQL/MP statement and you do not want to wait for it to finish.
You do not need to stop any other NonStop ODBC Server processes. Private
NOSUTIL processes are used by SCS and by some NonStop ODBC servers, but they
are automatically managed. You never need to stop SQL/MP SQLCOMP or SQLCAT
processes started by a NonStop ODBC server process. To stop the SQL operation,
stop the NonStop ODBC server process.
When you stop an SCS process, messages similar to these appear in the EMS log for
each NonStop ODBC server process that was running:

These messages are generated by the NonStop ODBC Server because it detects that
the SCS process has terminated, and attempts to reconnect.
Installing the Client on the PC
This subsection describes the procedures necessary for installing the client portion of
the NonStop ODBC Server product on a PC.
