Performing a Network Switchback 

To perform a network switchback from the alternate to the home system,
the following steps are required:

   1.  From the alternate system, enter the following commands:

            : NSCONTROL ABORT Return 
            : NETCONTROL STOP Return 

       This is required to stop the LAN and X.25.

   2.  From the OpenView DTC Manager workstation, perform the following:

          a.  Stop the OpenView DTC Manager.

          b.  Close all windows.

          c.  Exit windows.

   3.  From the DOS command on the OpenView DTC Manager workstation,
       change to the directory where the OpenView DTC Manager is
       installed.  For example:

            C: > CD DTCMGR Return 

       The DTC files that reside in this directory must contain the
       working configuration file, the backup configuration file, and the
       main configuration file.  For example:

            DTC01.DTC            the working configuration file 

            DTC01.BAC            the backup configuration file 

            DTC01.MAI            the main configuration file 

   4.  Copy the main configuration file over the working configuration
       file, for example:

            C:/DTCMGR > XCOPY DTC01.MAI DTC01.DTC/S Return 

   5.  From the OpenView DTC Manager workstation, restart the OpenView
       DTC Manger and perform the following:

          a.  Select DTC.

          b.  Log on.

          c.  Reset the DTC CPU.

          d.  Start X.25.

   6.  From the alternate system, enter the following command:

            : COPY NMCONBAC.PUB.SYS,NMCONFIG.PUB.SYS Return 

   7.  From both the home and alternate systems, enter the following
       commands to restart all network connections:

            : NETCONTROL START;NET=lan1 Return 
            : NETCONTROL START;NET=X25net Return 
            : NSCONTROL START Return
