ANR1820E

Explanation
 The server attempted to connect to the database
by using TCP/IP, but it was not able to do so.

System action
 The server stops.

User response
 First, verify that the port number is not already
in use.  Possible methods include:
 On Unix systems, inspect /etc/services for an occurance of the
port number.
Use the netstat command to determine if a service is listening
on the port number.

 If a conflict is detected, specify a different port number
on the DBMTCPPORT option in the server options file and restart the
server.
 If no conflict is found, use the "db2 get database
manager config" command to verify that the SVCENAME configuration
parameter is set to the port number identified by the message.  If
not, then use the "db2 update database manager config using SVCENAME
port number" command to manually update the configuration parameter.
 Ensure that the value specified is also specified on the DBMTCPPORT
server option. Restart the server.
 Finally, use the "db2set"
command to verify that the DB2COMM environment variable is set to
"TCPIP".  If not, then use the "db2set DB2COMM=TCPIP" command to set
the environment variable and restart the server.
