parameter
parameter. A name specified in a prepared command for which the user substitutes a value
when executing the command.
partition. The portion of a partitioned table, index, or physical file that resides on a particular
disk volume.
physical disk process. A DP2 process.
physical file name. The internal name by which a file is known to DP2. For a direct file, this
name is the same as the file name. For a file name-managed by SMF, the physical file
name is on a subvolume beginning with ZYS (for logically named files) or ZYT (for
logical templates). See also internal file name.
physical volume. A disk volume managed by DP2.
physical volume process. A DP2 process.
PHYSVOL option. A physical volume name optionally specified when a logical file is
created (either programmatically or through a command), instructing SMF to create the
file on that volume. Examples include CREATE interfaces and FUP RELOCATE.
pool. A collection of physical volumes managed by SMF. Also known as storage pool.
pool process. The SMF process managing a storage pool, with the same name as that
storage pool.
process identification number (PIN). A number assigned to a process for identification
purposes.
qualified file-set list. A list of file sets qualified by a clause (optionally) that selects objects
based on characteristics of the file. To determine which qualifiers are permitted, refer to
the syntax.
record. A basic unit of storage in a file or database pertaining to a particular item. A record
is the smallest logical unit of data that can be read from or written to a file. A record in
a relational table is represented as a row. A record can also be any audit record that
describes the outcome of a transaction. More specifically, a status record is either a
commit record or an abort record. A record can also be a Data Definition Language
(DDL) dictionary object that describes the structure of an Enscribe disk file. A record
usually includes file-creation information, which allows the File Utility Program (FUP) to
create a file from the record structure. If the file is to be key sequenced, a record also
contains the key attributes.
relative files. A file in which each new record is stored at the relative record location
specified by its primary key, and whose primary key is either a user-defined or system-
defined relative record number that indicates the record location. Each record location
can be regarded as a numbered slot that holds one fixed-length record, with the
primary key identifying the slot number. In general use, records can be updated or
