Use this directive to create a DSA. On completion of this directive,
the state of the DSA is OFF. You can then create subentities
of the DSA entity, and manage the attributes of the DSA entity and
its subentities.
Syntax:
CREATE DSA
When the DSA is being created, it reads its database into memory.
If the DSA does not have a database yet, it creates a new one
automatically.
DSAs on Tru64 UNIX systems use memory image files instead
of the snapshot files since V3.0. The DSA can read and write memory
image files much faster, especially for large databases. By default,
the DSA always reads a memory image file, if a valid one is
available. If not, it reads a snapshot file, if one is available, or
creates a new database if not.
You can use arguments to the CREATE DSA command to specify
which type of database file you want the DSA to read during
creation. If you use these arguments, the DSA only attempts to
read the specified type of database file, and does not fallback
to the other type or create a new database. See the Arguments
topic for further details.
After you have created the DSA for the first time, using the
CREATE DSA command with no arguments, you must set values for
the AE Title and Presentation Address attributes of the
DSA entity. You cannot enable a DSA that does not have these two
attributes set. This version provides a DSA configuration utility
that simplifies the setting of these attributes.
After creation for the first time you are also advised to set the
Volatile Modifications attribute to TRUE. Refer to the help for
this characteristic attribute for further details.
During subsequent DSA creations, the DSA refers to its own database
and configures itself automatically.
