Changing ViewPoint Configuration
•
Adding a new custom status server to the application.
To make such changes, you must stop ViewPoint, edit the PATHDEFS file, and then
restart ViewPoint from a cold state. When you cold start ViewPoint, it uses the changed
PATHDEFS file with its new configuration attributes. You should print a hardcopy of
the default PATHDEFS file supplied by ViewPoint before you edit PATHDEFS; you can
then edit the file with more confidence. The file is stored on your default logon
subvolume.
In some cases, the PATHDEFS file does not have an attribute setting you can change.
Many default attributes, such as the home terminal name, do not appear in the
ViewPoint PATHDEFS file. In this case, you must add a command. The command
could be a Pathway/TS SET TCP or SET PROGRAM, or a NonStop™ TS/MP SET
SERVER ASSIGN, or SET SERVER PARAM command.
Accessing Alternate TACL Segment Files
The VIEWPT command requires access to the TACL ZSPI definitions for SPI and
NonStop™ TS/MP. (Refer to the NonStop™ TS/MP System Management Guide.)
ViewPoint assumes that the files containing these definitions are in the default
subvolume $SYSTEM.ZSPISEGF for your site. If the files reside in a different
subvolume, you should ask your site administrator for the current default subvolume.
When you first use ViewPoint, the definitions are loaded into your private TACL
segment and your #USELIST is altered to contain the directory that holds the SPI and
NonStop™ TS/MP definitions. If another product uses the same definitions, both
products share the definitions.
TACL must be running on the terminal that initiates startup. The ViewPoint NonStop™
TS/MP application runs under the process access ID of the user that invokes the
command VIEWPT:STARTUP. The terminal on which VIEWPT:STARTUP is executed
becomes the home terminal of the ViewPoint NonStop™ TS/MP processes.
Adding New Server Attributes
When a command for a particular server attribute does not exist in the PATHDEFS file,
you must add SET SERVER ASSIGN or SET SERVER PARAM commands to specify
server assigns and server parameters, respectively. (Refer to Appendix A, “Server
Assigns and Parameters,” for a complete list of the assigns and parameters allowed for
ViewPoint servers.)
For example, suppose you want to place your EVENTCX file (containing custom event
text) on a different subvolume than your default program subvolume. To do this, you
add the CUSTOM-DETAIL assign to the attributes of the ZVPT-EVNT-DETL server.
The assign specifies where EVENTCX is located, as shown:
SET SERVER ASSIGN CUSTOM-DETAIL, $MYVOL.MYSUBV.EVENTCX
As an example of adding a server parameter, you might want to configure the
ZVPT-EXTRAS-DELETE program unit into your ViewPoint application. To do this,
