The default installation procedure places the DSE utility program in a directory specified by the environment variable gtm_dist.

Invoke DSE using the "dse" command at the shell prompt. If this does not work, consult your system manager to investigate setup and file access issues.

Example:

        
        
        $gtm_dist/dse
        File/usr/name/mumps.dat
        Region  DEFAULT
        DSE>
        
        

DSE displays the DSE> prompt.

You may also specify a command when entering DSE.

Example:

        
        
        $gtm_dist/dse dump -fileheader
        
        

This command displays the header of the file for the DEFAULT region, then returns to the shell prompt.

While DSE can operate concurrently with other processes that access the same database file, Fidelity Information Services strongly recommends using DSE in standalone mode when modifying the database, unless you are very knowledgeable about DSE and about how your application uses database files. Some DSE operations can adversely impact the database when they occur during active use of the database. Other DSE operations may be difficult to perform in a logically sound fashion because a DSE operator works on a block at a time, while normal database operations update all related blocks almost simultaneously.

In a logical dual-site environment, Fidelity recommends using DSE on the secondary whenever possible.

Use the DSE EXIT, or QUIT command to leave DSE.
