The Resource Definition Editor in Rational® Developer for System z® provides
support for defining CICS® resources.
Traditionally, the role of defining resources for CICS has been
the domain of the CICS system programmer. There has been a reluctance
to allow the application developer to define CICS resources for the following reasons:
- Most CICS resource
definitions have many parameters that because of their complexity, interrelationship
with other resource definitions, and shop standards require CICS systems
programming knowledge to define correctly. Incorrect definitions can cause
unexpected results that might impact the entire CICS region.
- Most customer shops provide CICS development and test environments
that must be available for shared use by multiple application groups and developers.
Many customer shops have Service Level Agreements in place for these environments.
Meeting these agreements requires strict control of the environments.
The Resource Definition Editor in Rational Developer for System z addresses
these issues by allowing the CICS system programmers to control CICS resource
definition defaults, and to control the display properties of a CICS resource
definition parameter. For example, the CICS system programmer can supply certain CICS resource
definition parameters that may not be updated by the application developer.
Other CICS resource
definition parameters may be updatable, with or without supplied defaults,
or the CICS resource
definition parameter can be hidden to avoid unnecessary complexity.
