Function

To change static network connections that have been previously defined. With this command you can only change static connections: those connections defined by a CONNECT initialization statement or an $ADD CONNECT command.

Parameters

MA|MEMBA|MemberA=n

The member number at the NODEA end of the connection.

Default: The default is 1. The value for MEMBERA if NODEA is the local node must be a 1. If the member number is greater than a 1 for the local node, the command is rejected.

MB|MEMBB|MemberB=n

The member number at the NODEB end of the connection.

Default: The default is 1. The value for MEMBERB if NODEB is the local node must be a 1. If the member number is greater than a 1 for the local node, the command is rejected.

NA|NODEA=xxxxxxxx|nnnn

The 1– to 8–alphanumeric or special ($, #, or @) character symbolic node name (xxxxxxxx) or node number (nnnn) at one end of the connection.

You can specify wild cards on this parameter. See Using wildcards for additional information.

The name must match the NAME= parameter of the NODE initialization statement for the referenced node.

NB|NODEB=xxxxxxxx|nnnn

The 1– to 8–alphanumeric or special ($, #, or @) character symbolic node name (xxxxxxxx) or node number (nnnn) at one end of the connection.

You can specify wild cards on this parameter. See Using wildcards for additional information.

The name must match the NAME= parameter of the NODE initialization statement for the referenced node.

PATHMGR={No|RESET|Yes}

Indicates whether this connection supports path manager type protocols. PATHMGR=RESET indicates that the value of PATHMGR= should be reset to the default.

Default: The default depends on the specifications for the NODEA= and NODEB= parameters.

• If either node is defined as PATHMGR=NO, the default is PATHMGR=NO.
• If both nodes are defined as PATHMGR=YES, the default is PATHMGR=YES.

REST=nnnn

An integer (2-8000) that represents the resistance rating of the connection as viewed by the installation manager and coordinated with other installations. For information about selecting resistances, see z/OS JES2 Initialization and Tuning Guide, SA32-0991.

Default: None

Authority Required

This command requires system authority. The description of the $T RDRnn command explains how to ensure that the authority of the appropriate MVS™ system command group is assigned.

This command requires control security access authority. For a description of assigning command input authority, see z/OS JES2 Initialization and Tuning Guide, SA32-0991.

Scope

Single member. The values supplied for this command will be in effect for this member only.

Depending on your installation's setup, however, you might want this command to be applied to all members of the MAS (to ensure a consistent environment across the MAS). If so, you can use the MVS ROUTE *ALL command to issue this command to all active members (if the JES2 command character is the same on all members). See z/OS MVS System Commands, SA38-0666 for more information on using the ROUTE *ALL command.

Messages

The $HASP815 message is issued in response to this command.

Example

 1   $T CONNECT, NODEA=PHOENIX,
   MEMBA=1, NODEB=TUCSON, MEMBB=1, RES=30

The above example changes the resistance between the PHOENIX and TUCSON nodes to 30.
