To connect local applications and tools to your Db2 database, you need to configure your environment.
Before you begin
- Install the
IBM® Data Server Driver Package for your
operating system.
- Decide whether you are using Secure Sockets Layer (SSL) to connect to your database or not.
- Collect database details and connect credentials, including the host name of your server and
your database user ID and password.
Procedure
-
Add entries to the driver configuration file, db2dsdriver.cfg, for your
database.
The configuration steps are different depending on whether you want to connect to your
database by using SSL or not:
Without SSL
To connect your applications and tools
to your database without using SSL, enter the following commands in a command shell on Linux
operating systems, at the Windows command prompt, or in a
Db2® command window:
db2cli writecfg add -database SAMPLEDB -host hostname -port 50000
db2cli writecfg add -dsn alias -database SAMPLEDB -host hostname -port 50000
Where:
- hostname is the host name of your server.
- alias is an alias that you choose. The alias cannot be the same as the
database name, SAMPLEDB. If you want to have spaces in the alias, surround the
alias with double quotation marks.
With SSL
To connect your applications and tools to your database by using SSL,
enter the following commands in a command shell on Linux operating systems, at the Windows command
prompt, or in a
Db2 command window:
db2cli writecfg add -database SAMPLEDB -host hostname -port 50001
db2cli writecfg add -dsn alias -database SAMPLEDB -host hostname -port 50001
db2cli writecfg add -database SAMPLEDB -host hostname -port 50001 -parameter "SecurityTransportMode=SSL"
db2cli writecfg add -database SAMPLEDB -host hostname -port 50001 -parameter "SSLServerCertificate=SampleSSLCert.crt"
Where:
- hostname is the host name of your server.
- alias is an alias that you choose. The alias cannot be the same as the
database name, SAMPLEDB. If you want to have spaces in the alias, surround the
alias with double quotation marks.
- SampleSSLCert.crt specifies the fully qualified name of a self-signed server
certificate or a certificate authority (CA) certificate.
Note: There is no need to configure the SSLServerCertificate keyword for a
connection to the Bluemix database.
-
Test connecting by issuing the db2cli validate command from the command
prompt:
db2cli validate -dsn alias -connect -user userid -passwd password
Where:
- alias is an alias you created with the db2cli writecfg
command.
- userid is your Db2 user ID.
- password is your Db2 password.
-
[Optional] To be able to connect local ODBC applications and tools to your database, register
the DSN with the ODBC driver manager:
Run the following command from a command line:
db2cli registerdsn -add -dsn alias
Where,
alias is an
alias you created with the
db2cli writecfg command. By default, the DSN is
created as a user DSN.
