Register the resource definition file, load the IMS database, and import IMS transactions. These three procedures are required to successfully run and interact with an IMS application on
Enterprise Server.
Register the Resource Definition File
IMS supports two transactions named /CIC and /IMS respectively. They are defined in a provided resource definition file,
dfhdrdat. When you register this resource definition file, it enables your
enterprise server region to switch back and forth between CICS and IMS modes. This is required to run the MFDEMO application.
In general, we recommend that you leave the provided
dfhdrdat file intact in its default location, and copy a new instance of the file into each project that requires it.
- Copy the default resource definition file installed with
Enterprise Developer,
dfhdrdat, from its installation directory to your project's
system directory. The default installation directory for
dfhdrdat is
%ProgramFiles(x86)%\Micro Focus\Enterprise Developer\etc\cas.
- At an
Enterprise Developer command prompt, change to your project's
system directory.
- Enter the following command:
caspcupg /dp=.
Load the IMS database
- In
Solution Explorer, right-click
DEMO03DD.DBD; then select
Database Utilities > Load.
This starts the
Load window for the database.
- Use the browse button for the
Input data set name field to browse to and select the
DEMO03DD.DBU file in your project's
loadlib directory; then click
Open.
- Click
Execute to initialize the database and load it from the
DEMO03DD.DBU input file.
- View the
Output
window
for confirmation of the load.
Import IMS transactions
When you migrate an IMS application from the mainframe to
Enterprise Developer, one of the required mainframe files is the stage 1 file containing your IMS transactions. In this demonstration, we have downloaded the MFDEMO stage 1 file for you, and then exported its contents to a flat text file,
trancode.txt, which is part of your project. You need to import this flat text file into the standard data file used by
Enterprise Server, named
imsgen2.dat. You do this by running the
mfims stage1imp command as follows:
- At your
Enterprise Developer command prompt, change to your project's
loadlib directory.
- Enter the following command:
mfims stage1imp trancode.txt
This command creates or updates the
imsgen2.dat file in your project's
loadlib directory.
