Controlling CTMPLEX

GSM manages dialogs with the operator, and ensures synchronization between all monitors in CTMPLEX. Operator-modified commands must be issued to GSM only. GSM then passes relevant commands to all LSMs, saves the current working profile, and provides the profile to new LSMs.

Table 122 Operator Commands

Operator Command

Description

S CONTROLM

Initially start the CONTROLM monitor on any system. The monitor becomes either a GSM or LSM monitor depending on whether there are other CONTROLM monitors of the same CTMPLEX.

F CONTROLM

Issue a command to Control‑M CTMPLEX. May be issued on the system where GSM runs.

P CONTROLM

Stop any LSM (when issued on the system where an LSM runs) or stop the entire CTMPLEX (when issued on the system where the GSM runs).

P LOCAL

Stop an LSM started by the S CONTROLM.LOCAL operator command.

Table 123 Operator Command Options

Option

Description

BALANCE

Activates or inactivates a Work Balancing mode, overriding the value of parameter BALANCEM (specified in the CTMPLEX initialization member). Valid values are:

YES – Activate Work Balancing mode.

NO – Deactivate Work Balancing mode.

STOPPLEX

Stops all LSM monitors. The GSM monitor continues working in regular (not CTMPLEX) mode.

Note: The stop operator command (P CONTROLM) issued for a GSM monitor stops all CONTROLM monitors of the corresponding environment. The stop command issued for an LSM stops that LSM only.

STOPGSM

Stops the GSM monitor. Valid values are:

system_identifier – If a system identifier is specified, the LSM monitor of the corresponding system (Sysplex member) becomes the new GSM.

'  ' (Blank) – If a system identifier is not specified, the first LSM that detects that the GSM has shut down becomes the new GSM.

LISTPLEX

Displays information about all monitors (GSM and LSMs) of the CTMPLEX.

STARTPLEX

Resumes CTMPLEX processing after environmental errors related to the CTMPLEX Coupling facility structure occur. After such errors, CTMPLEX stops all LSMs and the GLM continues working in standalone mode until the STARTPLEX command is issued.

WHOGLOBAL

Displays information about the GSM. This is the only CTMPLEX command valid for local monitors (LSMs).

DUMPPLEX

Issues a diagnostic dump (to any of SYS1.DUMPxx datasets) in order to obtain the contents of the CTMPLEX Coupling facility structure.

NEWPLEX

Enables dynamic refreshing of CTMPLEX parameters
