Executing Defined Processes

*ERROR* Security violation
Exiting from ViewPoint.
Executing Defined Processes
Define Process macros implement no security. They can be executed by anyone using
TACL on a system where the ViewPoint application is installed. The assumption is that
processes that are defined implement the desired security. Security checks by utilities
are normally based on process access ID; these are still effective—the user starting the
process must have the required authorization.
When using Define Process, be aware that defined and running utilities can be inherited
by different users who log on to the same terminal. This can be prevented by always
stopping all defined processes (PSTOP *) before giving up the terminal.
#LOGOFF has the effect of automatically stopping defined processes and exiting from
ViewPoint.
Memory Usage
ViewPoint uses an event cache stored in memory to improve the response time and CPU
usage of common event monitoring operations. Storing events in the event cache
allows for quick access by the screen display. You can configure the size of the cache
so it has enough storage space for your event monitoring purposes. ViewPoint uses
these guidelines to compute memory usage for a sixteen-event display page:
•
5 KB of memory for each display page
•
1 MB of memory for 200 display pages
You alter the number of events stored in the event cache with the PRIMARY-
CACHESIZE parameter located in your PATHDEFS configuration file. The default
value for this parameter is 320 events (20 pages). You can change this value by either
editing the PATHDEFS file directly or by running the Install routine to have it updated
automatically. For more information on running Install, see “ViewPoint Installation,”
the first subsection in this section. For more information on the PRIMARY-CACHE
parameter, see Appendix A, Server Assigns and Parameters
.
Version Information
The version of the loaded ViewPoint library is contained in the variable
T9640D20vnn^ddmmmyy^VIEWPOINT. The variable contains the version banner,
which is printed with the ViewPoint banner during terminal initialization. You can
access the directory that contains this variable by typing the following at the prompt:
variables :utils:viewpt
You can also find the contents of the version variable in the text variable
_VIEWPOINTVERSION.
