About this task
A
data set mapping associates the lowest level qualifier in each MVS™ data set to a file name extension
that is used for the related workstation-based file in your subprojects.
Procedure
To add a data set mapping:
- Open the z/OS File System Mapping view.
- Select the remote system you want to modify mappings for
from the System list.
- To add a data set mapping, right-click the table in the z/OS
File System Mapping view and select Add Data
Set Mapping. The Add Data Set
Mapping window opens.
- To add a member mapping, right click a data set mapping
in the z/OS File System Mapping view and select Add
Member Mapping. The Add Member
Mapping window opens.
- Specify a string in the Mapping criterion field. Data sets and members with names matching this string are included
in the mapping.
- Use ** as a wild card for matching one or more data set name segments
or qualifiers:
- **COBOL matches <any high-level qualifier>.<any
middle qualifier>.COBOL. Some examples of data set names
that match this mapping include:
- USER.COBOL
- USER.A.COBOL
- USER.A.B.C.COBOL
- USER.A.B.C.MYCOBOL
- **ERROR** matches <any high-level qualifier>.ERROR.<any
low-level qualifier>. Some examples of data set names that
match this mapping include:
- USER.ERROR.TEST
- USER.A.B.MYERROR.ABC
- USER.A.B.MYERROR2.ABC
- Use * as a wild card for matching within a data set name segment
or qualifier. For example, USER**COB* matches the following names:
- USER.A.COB
- USER.A.B.COBOL
- USER.A.B.ACOBCOPY
- You can also use a period as a delimiter in a mapping:
- USER.*.TEST matches USER.A.TEST, but not USER.A.B.TEST
- USER.**TEST matches USER.A.TEST, USER.A.B.TEST, and USER.A.B.CTEST.
- Fill in the properties for the rest of the fields as necessary.
- Click OK. The
new mapping appears in the table. Member mappings are added as children
of the data set mapping that you selected before clicking Add
Member Mapping. You can sort this table by any of the
headings shown in the view (such as Mapping Criterion, Workstation
File Extension, Transfer Mode, and so on). To sort the table, click
a table heading.
- Optional: You can override these system-wide
mappings by defining mappings for specific data sets or members by
following these steps:
- Right-click the data set or member in the Remote Systems
view and click Properties.
- Click Mapping in the list on
the left. The Mapping pane opens on the right. This
pane is similar to the Add Data Set Mapping window.
- Leave the option to inherit values selected for each
of the values you want to cascade from a higher level.
