Due to the above issue , I am not able to connect to DB2 on z/OS through DB2 connect . I am getting following error message when connect to DB2
via DB2 connect .

Code:
DB2 => connect to sholy7 user userid using password1

SQL30081N  A communication error has been detected.  Communication protocol
being used: "TCP/IP".  Communication API being used: "SOCKETS".  Location
where the error was detected: "172.20.85.101".  Communication function
detecting the error: "connect".  Protocol specific error code(s): "10061", "*
"*".  SQLSTATE=08001



I have tried with refresh DDF ( ie stop and start the DDF ) and Refresh VTAM connection for DB2 . But no effect . Still problem persist .

Could anyone of you please pass some light on this and help me to resolve this issue .


Thanks In advance

Regards
SenthilKumar K

Hello Rogerio,

Have you had your network support people verify your tcp/ip configuration?

If you try to "ping" your db2 ip address, what happens?

Hi ,

The above problem was due to IP address not getting resolved .
by DNS resolver .

We have added entry for this IP address in the /etc/host file in OMVS .


Code:
Format for adding the above entry :

hostname          ip-address

xxxx                 10.0.0.1


Thanks and Regards
senthil

Hello Rogerio,

Have you tried a tracert? How far does it go before failing (if it fails)?
