Use the following instructions to configure DB2 database aliases on Unix and Linux operating systems:
1. Login to the machine that contains your DB2 native client software.
2. su to your DB2 instance owner. For example:
 
su - db2inst1
 
3.
 Execute the .profile associated with the db2instance owner.
 For example:
 
. ./.profile
4. Use the echo command to ensure DB2DIR is set.
 
echo $DB2DIR
 
5.
 Use the echo command to ensure DB2INSTANCE is set.
 
echo $DB2INSTANCE
 
6.
 cd into the $DB2INSTANCE/sqllib/bin directory.
 
cd $DB2INSTANCE/sqllib/bin
 
7.
 Execute the db2 command.
 
./db2
 
8.
 Execute the catalog node command using the following syntax.
 
catalog tcpip node arbitrary_node_name remote database_server_name server db2_listening_port
 
Here is an example:
 
 catalog tcpip node WIN64IA remote openwin64 server 50000
9. Execute the terminate command.
 
terminate
 
10.
 Execute the catalog database command using the following syntax:
 
catalog database database_name as remotedb at node arbitrary_node_name_from_above
 
Here is an example:
 
catalog database sample as remotedb at node WIN64IA
 
11.
 Execute the terminate command.
 
terminate
 
11.
 Execute the connect to database command where database is the remotedb alias from step #10.
 For example:
 
connect to remotedb
 
12.
 Wait for a successful connection.
Use the remotedb alias in the database alias field of your DB2 Lite Data Source Names.
