The third method uses a data-base-access file to define the
remote data base. When using the DEFINE or DATA-BASE= command, you
enter the name of a data-base-access file rather than a data base
name. Refer to the IMAGE Reference Manual for
information on creating a data-base-access file. In this method,
QUERY automatically issues a REMOTE BYE and closes the DSLINE when
you enter the QUERY EXIT command.
Figure C-3 "Using Method 3" illustrates
Method 3 using DS. The user logs on to the local system, runs QUERY and
specifies a data-base-access file name with the DATA-BASE= command. The
data-base-access file contains the name of a remote data base and the commands
to establish a communications link and remote session to access the data base
DBR that resides on the remote system. Record 1 of the data-base-access
file specifies the remote system on which the data base resides
and the device class of the disc (DISCA) on which it resides. Record
2 specifies the Distributed Systems (DS line) and Record 3 indicates
the remote username and account name which is to be used to establish
a remote session for USERL.ACCTL.

NOTE: IMAGE verifies the content of the data-base-access file
and will accept only the DS syntax for the :DSLINE and :FILE commands.
This is due, in part, to the IMAGE restriction on the size of the
dsdevice name to 8 characters. If you are using NS, input the device
class name or logical device number in the first two records of
the data-base-access file.
