When you have finished configuring the DB2 Connect workstation for communications, perform the following steps to test the connection on a remote database. You will need to connect to a remote database to test the connection.
Step 1. | Start the database manager by entering the db2start command on the host database server (if it was not already started). |
Step 2. | Enter the following command in the DB2 Connect workstation's Command Center or command line processor to connect to the remote database: connect to database_alias user userid using password
|
The values for userid and password must be valid for the system on which they are authenticated. By default, authentication takes place on the host or AS/400 database server.
If the connection is successful, you will get a message showing the name of the database to which you have connected. You are now able to retrieve data from that database. For example, to retrieve a list of all the table names listed in the system catalog table, enter the following SQL command:
db2 "select tabname from syscat.tables"
When you are finished using the database connection, enter the db2
connect reset command to end the database connection.
![]() |
You are now ready to start using DB2. For more advanced topics,
refer to the Administration Guide.
|
If the connection fails, check the following items:
At the host:
__ 1. | The db2comm registry value includes the value tcpip. |
__ 2. | The services file was updated correctly. |
__ 3. | The service name (svcename) parameter was updated correctly in the database manager configuration file. |
__ 4. | The database was created and cataloged properly. |
__ 5. | The database manager was stopped and started again (enter the db2stop and db2start commands on the server). |
__ 6. | The port number specified is not being used by any other process.
|
If there are problems starting a protocol's connection managers, a warning message appears and the error messages are logged in the db2diag.log file.
For more information on the db2diag.log file, refer to the Troubleshooting Guide.
At the DB2 Connect workstation:
If the connection still fails after you verify these items, refer to the Troubleshooting Guide.
