Design Considerations
Use CANCEL or CANCELREQ only if it is unimportant for the application to
monitor whether or not the command was performed.
Pathway subsystems do not support the ALLOW-TYPE token or the RESPONSE-
TYPE token.
The PATHCOM MAXSPI parameter, which you set during the Pathway subsystem
startup and you can change only by stopping the Pathway subsystem, establishes
the maximum number of user-written processes that can simultaneously open an
interface to a Pathway subsystem. In the management programming interface,
ZMAXSPI is a field in the ZPWY-DDL-DEF-PATHWAY data structure.
The value you give for ZMAXSPI can range from 1 through 100. Until the Pathway
subsystem is started, only one process using SPI or one PATHCOM process can
open the PATHMON process.
Security is implemented for specific groups of commands and is described under
Security on page 3-24. For information about implementing security for access to
the PATHMON process, see the Safeguard Reference Manual.
SPI and the NonStop subsystems that support it are designed so that, under most
circumstances, you can install a new release of HP NonStop software on any one
of your systems without changing your existing management applications.
