Description
Whenever a local system application (SYSAP) requires a response from a remote
SYSAP, the local system assigns a unique number, called an RSPID, to the
response. The RSPID is transmitted in the original request (as a means of
identification), and the remote SYSAP returns the same RSPID in its response to
the original request.
The SHOW RSPID command displays information taken from the response
descriptor table (RDT), which lists the currently open local requests that require
responses from SYSAPs at a remote node. For each RSPID, SDA displays the
following information:
• RSPID value
• Address of the class driver request packet (CDRP), which generally represents
the original request
• Address of the CDT using the RSPID
• Name of the local process using the RSPID
• Remote node from which a response is required (and has not yet been
received)

You can find the cdt-address for any active connection on the system in the CDT
summary page display of the SHOW CONNECTIONS command. CDT addresses are
also 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.
