Preloading Panel
Description Files
Preloading a panel description file enables users to avoid the performance cost
associated with disk I/O when an NCL procedure displays a panel description file. A
panel description file is said to be preloaded when it is loaded in memory before an
NCL procedure displays the panel resulting from the panel description file. The
practice of preloading insulates users from the performance costs exacted by reading
the panel description file and determining how to display the resulting panel on the
screen, and provides the fastest possible response times for NCL procedures that
display panels.
To preload a panel description file, issue the SYSPARMS PPRELOAD command,
followed by the name of the panel description file. For example, to preload a panel
description file named TESTPANL, issue the following command:
SYSPARMS PPRELOAD=TESTPANL
Preloading During the
NonStop NET/MASTER MS
Startup Phase
Panel description files can be preloaded during the NonStop NET/MASTER MS
startup phase by including the PPRELOAD command in the INIT or READY NCL
procedure. However, preloading panel description files during NonStop
NET/MASTER MS startup increases startup time.
Preloading Commonly Used Distributed Panel Description Files During the INIT NCL Procedure
Startup Phase
The distributed INIT NCL procedure has a series of SYSPARMS PPRELOAD
commands to preload commonly used distributed panel description files; however, by
default, these panel description files are not preloaded. To explicitly specify whether
to preload these panel description files, create a customized INIT NCL procedure
using Method 1, described in Section 3, “Configuring NonStop NET/MASTER MS,”
and use a CALL core statement from the customized INIT NCL procedure that calls
and passes an initialization option to the distributed INIT NCL procedure. The
following syntax is used:
CALL INIT( [ PRELOAD | NOPRELOAD ], [ RMSBASE | NORMSBASE ] )
PRELOAD
specifies that panel description files are to be preloaded during NonStop
NET/MASTER MS startup.
NOPRELOAD
specifies that panel description files are not to be preloaded during NonStop
NET/MASTER MS startup.
