EZD1971I

Explanation
 The control connection to the non-z/OS target
could not be established.  The non-z/OS target cannot be used for
distributed connections.  The control connection can fail if no route
is available to the target, or if  there is a problem with the sysplex
distributor agent server on the target.
 In the message text:
 ip_addr 
The IP address of a distributed non-z/OS target.
errno 
A UNIX System Services return
code from a failing Connect( ) call. These return codes are listed
and described in the return codes (errnos) information
in z/OS UNIX System Services Messages and Codes.
errnojr
The hexadecimal UNIX System
Services reason code from a failing Connect( ) call. The format of
the 4-byte reason code is explained in the introduction to the reason codes (errnojrs)  information in the
 z/OS UNIX System Services Messages and Codes, where the reason codes are  listed. 

System action
 TCP/IP continues.

Operator response
 Contact the system programmer. 

System programmer response
 Fix the problem after analyzing the
return code and the reason code.  For example, if the return code
is 00000468 (ECONNREFUSED), verify that the sysplex distributor agent
server is in LISTEN state and that it is accepting new connections.
 After you fix the problem, the sysplex distributor will establish
the control connection because the sysplex distributor periodically
tries the connection attempt again.

User response

Automation
 This message is written to the system console.
This message is a good candidate for automation. Automation can allow
you to monitor the status of sysplex distributor control connections
to non-z/OS targets.
