Controlling Access to
a User Database (UDB)
Before NonStop NET/MASTER MS can work with an Enscribe file, the file must be
opened for system-wide access—that is, for access by NonStop NET/MASTER MS—as
a user database (UDB). Certain important files are automatically opened for system-
wide access during NonStop NET/MASTER MS startup. These files, which are
located in $isv-vol.ZNNMDATA after the REPSUBSYS phase of the Install program,
are listed in Appendix A, “File Reference.”
For files required by an NCL application that you write, use the UDBCTL commands
to control system-wide access to the files by NonStop NET/MASTER MS, and the
FILE verbs to control access to the files by the NCL application.
Refer to the NonStop NET/MASTER MS Command Reference Manual for more
information about the UDBCTL commands. Refer to the NonStop NET/MASTER NCL
Reference Manual for more information about the FILE verbs. Refer to the NonStop
NET/MASTER NCL Programmer’s Guide for more information about how to use the
UDBCTL commands and the FILE verbs to control access to UDBs.
Controlling Access to
a Pathway Server
Class
An NCL process can act as a PATHSEND requester to communicate with existing
Pathway server classes. An NCL process can send a request message to the server
class and receive a reply message from the server class.
Before NonStop NET/MASTER MS can work with an existing Pathway server class,
the Pathway server class must be opened for system-wide access—that is, for access by
NonStop NET/MASTER MS. Use the PSNDCTL commands to control system-wide
access to a Pathway server class by NonStop NET/MASTER MS. Use the PSEND
verbs to control access to the Pathway server class by an NCL application.
Refer to the NonStop NET/MASTER MS Command Reference Manual for more
information about the PSNDCTL commands. Refer to the NonStop NET/MASTER NCL
Reference Manual for more information about the PSEND verbs. Refer to the NonStop
NET/MASTER NCL Programmer’s Guide for more information about how to use the
PSNDCTL commands and the PSEND verbs to control access to a Pathway server class
by NCL.
