A DB2® instance is
an environment in which you store data and run applications. Use the db2icrt command
to create an instance.
Before you begin
On Linux or UNIX operating systems, you must have root user
authority.
Note: If the DB2 fault monitor
is turned on, the DB2 instance
is started automatically when the db2icrt command
finishes running. You can stop the instance by using the db2stop command.
Procedure
To create an instance using db2icrt:
- Log in with proper authority.
- Run the db2icrt command. For
example, on Linux or UNIX operating systems:
DB2DIR/instance/db2icrt -a AuthType -u FencedID InstName
where:
- DB2DIR
- is the DB2 installation
directory.
- On AIX®, HP-UX, or Solaris
operating systems, the default DB2 installation
directory is /opt/IBM/db2/V9.7.
- On Linux operating systems,
the default installation directory is /opt/ibm/db2/V9.7.
- -a AuthType (Linux or UNIX)
- Represents the authentication type for the instance. AuthType can
be one of SERVER, CLIENT, or SERVER_ENCRYPT. SERVER is
the default. This parameter is optional.
- -u FencedID
- Represents the name of the user under which fenced user defined
functions (UDFs) and fenced stored procedures will run. This flag
is not required if you are creating an instance on a client. Specify
the name of the fenced user you created.
- InstName
- Represents the name of instance. The name of the instance must
be the same as the name of the instance owning user. Specify the name
of the instance owning user you created. The instance will be created
in the instance owning user's home directory.
Example
For example, if you are using server authentication, your
fenced user is db2fenc1, and your instance owning user is db2inst1,
use the following command to create an instance on an AIX operating system:
/opt/IBM/db2/V9.7/instance/db2icrt -a server -u db2fenc1 db2inst1
What to do next
(Optional)
After you create an instance you can configure notification for health
monitoring. This task can be performed using the Health Center or
CLP.
