SHOW CONNECTIONS
SHOW CONNECTIONS
Displays information about all active connections between systems
communications services (SCS) processes or a single connection. This command
displays information that is in the connection descriptor table (CDT).
Format
SHOW CONNECTIONS {/ADDR or /ADDRESS=cdt-address | /NODE=name |
/SYSAP=name}
Parameters
None.
Qualifiers
/ADDR or /ADDRESS=cdt-address
Displays information contained in the connection descriptor table (CDT) for a
specific connection.
9
/NODE=name
Displays information contained in the connection descriptor table (CDT) for a
specific node.
/SYSAP=name
Displays information contained in the connection descriptor table (CDT) for a
specific system application (SYSAP).
Description
The SHOW CONNECTIONS command provides a series of displays.
The CDT summary page lists information regarding each connection on the
local system, including the following:
• CDT address
• Name of the local process with which the CDT is associated
• Connection ID
• Current state
• Name of the remote node (if any) to which it is currently connected
The CDT summary page concludes with a count of CDTs that are free and
available to the system.
SHOW CONNECTIONS next displays a page of detailed information for each
active CDT listed previously.

You can find the cdt-address for any active connection on the system in the CDT
summary page display of the SHOW CONNECTIONS command. In addition, CDT
addresses are stored in many individual data structures related to SCS connections.
These data structures include class driver request packets (CDRPs) and unit control
blocks (UCBs) for class drivers that use SCS and cluster system blocks (CSBs) for the
connection manager.
