Introduce a new application, which has been provided in
one or more data sets, into a running CICS system without affecting
continuous availability.
About this task
- The application has been provided in one or more PDS or PDSE
data
set. The application could be a third party (vendor) product that
is provided as a set of application artifacts in one or more PDS or
PDSE data set or a new in-house application.
- You cannot restart CICS at this time, to apply the fix.
- The person who performs the action has the appropriate access
authorization.
Procedure
-
Define a LIBRARY resource that includes the data set or
data sets containing the new application.
Typically, the
application will have no intersects with any existing LIBRARY resources
and can use the default ranking value.
Use
one of the following methods to define the LIBRARY resource:
-
The Business Application Services (BAS) component of
CICSPlex®
SM.
-
The
CICS®
resource management
transaction CEDA.
-
The
CICS
offline CSD utility
program DFHCSDUP.
- The EXEC CICS CREATE LIBRARY command.
-
The
CICS Explorer®.
You can use the
CICS
Explorer
to define a LIBRARY resource in a single
CICS
region, or in the data repository for the
CICSplex, or in a
CICS
bundle.
For information about the management of resources defined in
CICS
bundles, see
Characteristics of resources in CICS bundles.
-
If you did not use EXEC CICS CREATE to define the LIBRARY,
install the new LIBRARY resource using CEDA, the
CICSPlex
SM WUI, or the
CICS Explorer.
-
Define to CICS the programs, and map sets that make up
the application and transaction definition or definitions that
reference
it.
-
Install the programs and other definitions.
Results
The new application is installed in the CICS production
system and continuous availability is maintained.
