Configuring for Application Access to $SSCP
CONFIGURING FOR APPLICATION ACCESS TO $SSCP
For purposes of network management, two components of the SNAX
Service Manager ($SSCP) are accessible to an application:
• The CNM Component allows an application to do standard SNA
network management and maintenance functions by using either
REQMS and RECFMS or NMVTs. Although several applications
can be configured to have access to this component, only one
can have access to it at a given time (concurrent access by
several applications is not possible).
• The CONFIG Component allows an application to use some of the
services offered by Tandem's CMI/CMP. Several applications
can concurrently have access to the CONFIG component. Using
this component, an application can do the following:
1. An application can get the STATUS of $SSCP, of
applications, of lines, PUs, and LUs.
2. An application can get STATISTICS of the SSCP and of
lines, PUs, and LUs.
3. An application can issue a SETLIMITS on counters of lines
and PUs to cause information to be returned when a counter
exceeds a given threshold.
Programmatic access to either or both of these $SSCP components
requires both an application file-system OPEN of $SSCP and
$SSCP's acceptance of a VERB^CONNECT from the application. The
application's VERB^CONNECT will be rejected if the application
has not been defined to $SSCP in a CMI ADD APPL command.
Furthermore, if the optional attribute PASSWORD is specified
in the ADD APPL command for that application, the designated
password must be included in the VERB^CONNECT, or $SSCP will
reject that verb. (The password should consist of eight
characters; if you use fewer characters, the password field must
be blank-filled to the right.) If no password is specified
through CMI, the password field of the VERB^CONNECT must be
filled with zeroes.
You use the CMI ADD APPL command to designate applications that
are to have access to $SSCP. For each application, you must
provide:
• An application name
• $SSCP components (CNM and/or CONFIG) that the application will
access
The following sample CMI command designates that application
APPL1 will have access to both the CNM and the CONFIG components
