138 CICS Transaction Gateway V5
To create our environment, we performed the following steps.
HFS data set creation
We created a new HFS and mounted it at the directory /usr/lpp/ctg500, where we
installed the CICS TG code.
To set up an HFS, you can allocate it using either ISPF option 3.2, an IEFBR14
batch job, or through the ISHELL menus. You should make sure that the storage
class with which your file is allocated has the GUARANTEED SPACE attribute.
For our /usr/lpp/ctg500 directory we created a data set with a data set name of
CTGUSER.CTG500.HFS. Figure 7-2 shows how we set up our HFS using TSO
option 3.2.

Once the HFS data set has been allocated, you must mount it at an HFS
directory, known as a mount point, with a TSO MOUNT command or by using
Option 3 from the ISHELL File_systems menu. The mount point should be an
empty directory; otherwise its contents will be hidden (but not deleted).
We created our directory in OMVS using superuser authority as shown in
Example 7-2 on page 139. First we changed to the /usr/lpp directory and issued
