I) Setup required at the server
 From the Configuration Assistant (CA) a) DB2COMM
Choose Configure

DB2 Registry b) SVCENAME
Choose Configure

DBM configuration
Or
Find “Communications” section.
 From the Control Center a) DB2COMM
Right click on instance and choose “Set up communications...” b) SVCENAME
Right click on instance and choose “Configure parameters...”
Find “Communications” section.
Bina Nusantara University myhost.ibm.com
Instance “DB2” mydb1
DB2COMM=TCPIP
Port = 50000
User defined in O/S:
User ID = myuser
Password = mypsw

Or
 Manually using commands: a) SVCENAME (service name) in DBM CFG update dbm cfg using svcename <port # or service name>
If you use a service name, ensure to update these files:
–
Linux: /etc/services
–
Windows: c:\winnt\system32\drivers\etc\services
Example: db2cdb2inst1 50000/tcp b) DB2COMM in the DB2 Registry db2set DB2COMM=TCPIP

II) Setup required at the client
Client
Application connect to mydb1 user myuser using mypsw db directory mydb1 node directory mynode
Two commands to run at the client:
1) catalog tcpip node mynode remote myhost.ibm.com
server 50000
2) catalog database mydb1 at node mynode
Bina Nusantara University 10

Putting both setups together: At the client and server
Client db directory node directory myhost.ibm.com
Instance “DB2”
Application connect to mydb1 user myuser using mypsw mydb1 mynode network mydb1
Two commands to run at the client:
1) catalog tcpip node mynode remote myhost.ibm.com
server 50000
2) catalog database mydb1 at node mynode
Bina Nusantara University
DB2COMM=TCPIP
Port = 50000
User defined in O/S:

• The Configuration Assistant will allow you to catalog databases with invalid hostnames, port numbers, etc.
• Everything might look correct; however, when you try to connect to the database, you will receive a connection error!
• Also ensure the user ID and password you provide to connect to the remote database is correct
– By default the authentication takes place on the DB2 server you are trying to connect to, therefore, you must provide a user ID and password defined on that server

Search and Known methods (Discovery Mode)
Search the network for any server
Enter server name and choose protocol
Bina Nusantara University 16

• Search and locate DB2 servers on the network
• Requires the DAS to be running on the DB2 server in order to discover databases
• Can prevent or "hide" a server / database from being discovered by setting the appropriate DAS,
Instance, and Database level configuration parameters

• If you are configuring a large number of servers or clients, rather than set up each one individually, you can fully set up one, export a profile (i.e. configuration file) from it, then apply the profile to the other clients/servers
• This saves an administrator a lot of time when setting up the environment
