Sterling Connect:Direct for UNIX statistics XIPT016I + XSMG621I + XSMG631I + XSMG601I

Technote (troubleshooting)


Problem(Abstract)

Sterling Connect:Direct for UNIX statistics showing errors:
XIPT016I
XSMG621I
XSMG631I
XSMG601I

Symptom

The combination of error messages below is the result of the UNIX® netmap containing a remote node definition with sess.pnode.max set higher than the remote node will allow.

The errors messages are issued when the Sterling Connect:Direct for UNIX attempts to establish more sessions than the remote node will allow.

If the remote node netmap specifies the same number of sessions as the UNIX® netmap, the messages may still be issued if the total maximum sessions of the remote node are exceeded. For example, if remote node is Sterling Connect:Direct for z/OS and the number of sessions exceeds the Sterling Connect:Direct for z/OS MAXSECONDARY init parm value. The Sterling Connect:Direct for z/OS JESMSGLG would contain a message indicating that the MAXSECONDARY value had been exceeded
- STAA005I - TASK NOT CREATED. MAX SECONDARY TASK COUNT REACHED.

The XSMG601I message text will be "SMGR (snode) didn't receive FMH68 during session start." when Secure+ is used for the connection from Sterling Connect:Direct for UNIX to the remote node.

Diagnosing the problem

To reference meaning, cause and solution for Sterling Connect:Direct messages, refer to the Message Lookup utility for your product.


Resolving the problem

Set the session limits to the same value on both remote node entries.

Note: No change to the .local node is required.

For example,  if  Sterling Connect:Direct for z/OS defines a remote Sterling Connect:Direct for UNIX with maximum 4 session then the Sterling Connect:Direct for UNIX netmap should define a limit of 4 outbound sessions to the remote z/OS system. 

z/OS Netmap . Adjacent node entry for remote Sterling Connect:Direct for UNIX is setting a limit of two inbound sessions.

ADJACENT.NODE=(                                       -
               (unix.node.name,port,ipaddress,TCP)  - 
               PARSESS=(2 1)                          - 
              
 SESS.SNODE.MAX=2                       -
               ENVIRONMENT=UNIX                       -
              )                                        

Sterling Connect:Direct for UNIX should limit its outbound sessions in the remote node netmap entry for this Sterling Connect:Direct for z/OS system to 2 sessions.

netmap.cfg
 zos.node.name:\
::descrip=zOS:\
:sess.total=4:\
:sess.pnode.max=2:\
:sess.snode.max=2:\
