FastSort Components

SORTPROG process (the actual sort-merge process)

Record generator (RECGEN) process, if SQL/MP is installed on your system
When you want to sort or merge records interactively or through a command file (IN
file), you use interactive FastSort. When you want to sort or merge records in an
application, you invoke programmatic FastSort through system procedure calls.
Interactive or programmatic FastSort can start a SORTPROG process, which performs
the sort or merge operation.
Figure 1-2 on page 1-5 shows how the first three FastSort components work together.
Component Program File Description

System
Procedures
$SYSTEM.SYSnn.OSIMAGE Programmatic FastSort – Library file for
FastSort system procedures
SORTPROG $SYSTEM.SYSnn.SORTPROG * A single serial sort-merge process, or
parallel sort-merge processes including:
A distributor-collector process
2 to 8 subsort processes
RECGEN $SYSTEM.SYSnn.RECGEN * Record generator (RECGEN) process
for the parallel creation and loading of
partitioned indexes (if SQL/MP is
installed on your system)
In $SYSTEM.SYSnn notation, nn is a two-digit number assigned by HP.
