Shifting Control-D monitors to another LPAR

It is sometimes necessary to shift the Control-D monitors to another LPAR without shutting down all decollation and printing monitors. To shift monitors, use the RESTART command.

The RESTART command has the following syntax:

where

• monitor_name – name of the monitor (main monitor, secondary monitor, or Print monitor). The default is the main monitor.
• lpar_name – name of the LPAR to which to shift the monitor. This LPAR name should be defined in the CTDPLEX member. The default is the first active LPAR from the corresponding entry in CTDPLEX.

To shift the main monitor, issue the following operator command:

or

The main Control-D monitor does not start any new mission processes. It shuts down on the current LPAR and restarts on the new LPAR.

Before the main monitor restarts on the new LPAR, the following message is displayed on the operator console where the modify command was issued:

The main monitor then shuts down with the following message:

If the main monitor does not start successfully on the new LPAR, the following message is issued by the old main monitor, and it continues to work:

The following message is displayed on the operator console when the main monitor starts on the new LPAR:

where nday_mode is INT(internal) or EXT(external) NEW DAY procedure mode.

Note: The SYSPLEX member of the CTD PARM library is not read by the new main monitor, but it is passed from the old monitor to the new monitor.

To shift the secondary decollation monitor or any Print monitor, issue the following operator command:

This option is available if lpar_name is defined for the monitor_name monitor in the CTDPLEX member.

The main monitor issues the STOP command for the decollation monitor or print monitor, and then issues the START command on the new LPAR.

Note: The RESTART command cannot be used for the main monitor if the CTDMON#, PRTMON#, or GENCLAS parameters of the CTDPARM member have been changed. In such a case, use the full procedure for regular restart of monitors.

The RESTART command is available under the following definitions in CTDPLEX:
