SNAXUTL ALLOCATE Command
The SNAX/XF Utility
A–20 097841 Tandem Computers Incorporated
ADD SETLOG Command This command is used to add to the SET table a record representing a BIND table.
ADD SETLOG bind-table-name
, FILENAME filename
bind-table-name
is the table name of the BIND table. The value specified for bind-table-name
can contain from one to eight alphanumeric and special characters.
FILENAME filename
is the name of the table source file in which the BIND table can be found. If you
are running SNAXUTL on a volume and subvolume different from those on which
the table source file resides, the value specified for filename must be fully
qualified. This is the same file that was created using the SELECTFILE TYPE
LOGMODE command.
The following is an example of how to add a BIND table and table source file name to
the SET table:
BEGIN
SELECTFILE snxset , TYPE SET
ADD SETLOG BINDTAB1, FILENAME $DATA.TABLES.LOGTAB1
END
BINTAB1 is the name of the source BIND table $DATA.TABLES.LOGTAB1.
SNAXUTL ALLOCATE
Command
The ALLOCATE command is used to allocate a new SET, ESS, or BIND table. When
the ALLOCATE command is executed, both the source and object files are allocated.
The two files will be equal in size.
ALLOCATE extent-size
extent-size
specifies, for the file being allocated, the number of pages, each containing 2048
bytes, that an individual extent will contain. The file system can automatically
allocate up to 16 extents for any given file. Thus, were you to specify extent-
size as 20, your file could contain a maximum of 320 pages (16 * 20). Tandem
recommends that you specify 10 pages. If you wish to calculate extent-size
yourself, see the information below.
If you know the number and types of records to be contained in a file, you can closely
estimate the extent size you need to specify. In the following sections are formulas for
calculating the extent size for each of the file types (SET and ESS). Extent sizes do not
need to be calculated for BIND tables.
