INTEGRATING APPLICATIONS
Avoiding Conflicting Box Names
If boxes with the same name have different access modes, you may
not be able to use the applications in the way that you expect.
For example, suppose that you use the following commands to
generate two applications:
SET RECORD c-rec SET RECORD c-rec
SET DATAFILE cfile SET DATAFILE cfile
SET DELETE OFF
SET UPDATE OFF
SET INSERT OFF
ADD BOX new-box ADD BOX new-box
SET APPL PATHCOMFILE p4 SET APPL PATHCOMFILE p3
SET APPL TREE (01 new-box) SET APPL TREE (01 new-box)
ADD APPL new-appl2 ADD APPL new-appl1
GENERATE new-appl2 GENERATE APPL new-appl1
The SET SERVER ASSIGN commands for these applications would
appear as follows:
SET SERVER ASSIGN (new-box, cfile, INPUT) (for new-appl1)
SET SERVER ASSIGN (new-box, cfile) (for new-appl2)
If you enter both of these commands in the same PATHCOM command
file and then establish a PATHWAY system with that command file,
the General Server uses the access mode of the SET SERVER ASSIGN
command that appears last in the command file. If the SET SERVER
ASSIGN command for "new-app2" appears last, both applications
will work as expected. If the SET SERVER ASSIGN command for
"newappl1" appears last, "newappl2" will not work as expected;
that is, you will not be able to use this application to delete,
insert, or update records because the access mode (INPUT) with
which the General Server will open the file will not permit these
operations.
If you plan to integrate your applications into a single PATHWAY
system, you can avoid using conflicting box names by doing the
following:
1. Describe, name, and add the boxes necessary for an
application.
2. Add the application to the object table.
3. Repeat steps 1 and 2 until you have named and added every
application to be integrated.
4. Use the GENERATE * command to generate all of the
applications.
