Coupling facility structure connections

Each 

BMC AMI Ops Automation

 subsystem creates one connection to the coupling facility structure.

The maximum number of connections allowed for a structure is controlled by a CFRM parameter and this parameter directly controls the maximum number of BMC AMI OpsA subsystems that can connect or share a structure.

Use the Format utility for couple data sets to change this parameter. An example of the statement follows:

ITEM NAME(CONNECT) NUMBER(nnn)

For z/OS version 1.7 and later, the default for nnn is 32, the minimum is 1 and maximum is 255.

See the section "CFRM Parameters for Administrative Data Utility" in the IBM publication z/OS MVS Setting Up a Sysplex for more information.

If you set the maximum number of connections to 255, as many as 255 BMC AMI OpsA subsystems can connect to the structure and share sysplex variables.

To display the current maximum number of connections allowed to a structure, issue the following MVS command:

D XCF,COUPLE,TYPE=CFRM
