SQL30081N A communication error with error code 10061

[ravi chandra]

Dear all ,
I am getting the following error while connecting from any one of my client,s CONTROL CENTER (if I am cataloging from command prompt there is no error) to db2 server

SQL30081N A communication error has been detected. Communication protocol being used: "TCP/IP". Communication API
being used: "SOCKETS". Location where the error was detected: "192.168.100.47". Communication function detecting the
error: "connect". Protocol specific error code(s): "10061", "*", "*". SQLSTATE=08001

my client details : windows, db2 v9.1(for all clients)
server details : linux db2 8.2
I already set db2comm= TCPIP
i found somewhere the port must be UNUSED, what is the meaning of that?
In service file also I found port details currectly
telnet also working fine
1Q)I restarted the db2 server , the instance is started but with an error SQL1063, to over come this is whether I have to run db2licm –a (whether I have to provide licence from outside disk, can I find with in the server??? But same error showing since 2 to 3 years but there is no issue till now)
2Q)I think I have to work on DAS(database administrator server)
How can I check whether db2admin is on or not??
Pls let me know how AUTHENTICATION (dbm cfg parameter) will play key roll???
How I have to set this for AUTHENTICATION for db2 admin, db2 server and client???

The AUTHENTICATION for db2 admin is SYSTEM_ENCRYPT
The AUTHENTICATION for db2 server is SYSTEM
The AUTHENTICATION for db2 client is SYSTEM

In db2 server svcename (dbm cfg parameter) is set to port number instead of name. I think it wont be problem.

Other then above points I am missing any important thing.

Pls help me out…………………..

Hi Ravi,

If you really have communication error then you can look at below link. But I don't think as in your case you can work perfectly from the command prompt. Even then go to below link and look at the probable cause of the error.

1) SQL1063 -- I guess by this you meant SQL1063N, which is a warning once you start the database manager using dbstart and that's fine. It's now an error.

2) For using control centre you must have a das running on the server. use db2admin on teh command prompt to know the das for your server. you can also use db2 get admin cfg to know the das configuration parameters.

ps -ef|grep -i das and check if das is up and running fine.

Check the das cfg setting at information centre for more information

Cheers, Vijay
