INTEGRATING APPLICATIONS
Avoiding Conflicting Box Names
Since the General Server can assign only one physical file to a
box name, boxes with the same name must represent the same file.
Consider, for example, the following ENABLE commands used to
generate two applications:
SET RECORD a-rec SET RECORD b-rec
SET DATAFILE afile SET DATAFILE bfile
ADD BOX my-box ADD BOX my-box
SET APPL PATHCOMFILE p1 SET APPL PATHCOMFILE p2
SET APPL TREE (01 my-box) SET APPL TREE (01 my-box)
ADD APPL my-appl1 ADD APPL my-appl2
GENERATE APPL my-appl1 GENERATE APPL my-appl2
You cannot integrate these applications into the same PATHWAY
system because "my-box" in "my-appl1" represents a data base file
named "afile" while "my-box" in "my-appl2" represents a data base
file named "bfile."
Since the values of the ABILITY attributes determine the access
mode with which the General Server can open a data base file,
boxes with the same name must also have compatible values for
these attributes. The General Server cannot assign a file to
box when the file is assigned more than one access mode.
Table 11-1 lists the access modes and the values for the ABILITY
attributes that correspond to these access modes.
