Repackaging Services
Into Servers
The Pathmaker product helps you repackage existing services into existing servers or
into new servers. In either case, the exact repackaging steps depend on whether you
want to move the service from one server to another server or simply add the service
to another server without removing it from the previous server. In both cases, you
must regenerate the mapping requester and, if the application is in a production
environment, copy the server object code to the production environment and the
mapping requester’s SCREEN COBOL code to the application’s SCREEN COBOL
object library files (POBJCOD, POBJDIR, and POBJSYM).
Tandem supplies an Enform query, PM19, that specifically reports on the services
included in each server. Refer to the Pathmaker Reference Manual for a description on
how to use Enform to produce this report.
Repackaging Services Into
Existing Servers
The simplest way to repackage a service is to use the Pathmaker product to add the
service to the list of services for another server and regenerate that server. You do not
have to remove the service from the server or servers in which the service was initially
included because services can be included in more than one server. When the altered
server has been regenerated, you must reassign the active server class for that service
and regenerate the mapping requester.
In some cases, you will want to move a service from one server to another server; that
is, remove the service from the list of services for a server and include it in the list of
services for a different server. In the following procedure, assume that you want to
move a service from one server to another server. The following procedure is one way
to move a service:
1. Run the Pathmaker full screen interface. The Pathmaker Main Menu appears.
2. Delete the service from the first server.
3. Regenerate the first server.
4. Add the service to the second server.
5. Regenerate the second server.
6. Assign the active server class (optional).
You must perform this step if your service is packaged in more than one server, or
if the server has more than one server class. If the service is packaged into one
server and that server has only one server class, the Pathmaker product
automatically assigns the single server class as active for the service.
7. Regenerate the mapping requester.
