SAS Safety Scalable Performance Data Server 4.5 Manual Do Utilizador

libnames.parm file as a central tool to control SPD Server domain resources and user
access to SPD Server domains.

To define an SPD Server domain in the libnames.parm file, you must define the domain
as a LIBNAME and define the path that points to the directory where data files for the
domain are stored.

LIBNAME=domain-name PATHNAME=primary-metadata-path
<optional specifications>
   OPTIONS="option-1 <...option-n>"
   ROPTIONS="option-1 <...option-n>"
   OWNER=owner-id
   LIBACLINHERIT=<YES/NO>
   DYNLOCK=<YES/NO> ;

The domain name that is associated with the LIBNAME must follow standard SAS
LIBNAME nomenclature rules. The PATHNAME= specification defines the computing
path that will contain the metadata tables that are associated with the domain. By default,
the PATHNAME= specification also will contain the data tables, index tables, and
intermediate tables that the domain creates. SPD Server administrators and users can use

 to enhance computational performance by specifying

separate paths for domain data, index, and work tables. All SPD Server domain names must
be unique. Different SPD Server domains should never share the same domain path.

Examples of simple libnames.parm file domain declarations follow:

LIBNAME=spds123 PATHNAME=c:\data\spds123;

LIBNAME=123spds PATHNAME=c:\data\123spds;

LIBNAME=_under PATHNAME=c:\data\_under;

LIBNAME=under_ PATHNAME=c:\data\under_;

The libnames.parm file is the preferred method to declare domains for use in SPD Server.
Users can connect to domains by submitting SAS code to SPD Server after a session has
started. The example SAS code below connects to the first domain that was declared
previously:

LIBNAME spds123 sasspds 'spds123'
  server=d8488.5200
  user='anonymous';

You can specify optional path parameters for a domain in libnames.parm libref statements.
