3. Abstract
CICS V5 introduces significant capability to help manage CICS as
a private cloud. The Platform definition can monitor the health of
shared services and maintain consistency across regions
simplifying application deployment while threshold policies can
protect production systems against rogue applications by enforcing
coding standards throughout the development lifecycle. See how to
use these new resources in conjunction with existing facilities
including CICS Monitoring and tools like CICS PA to manage and
measure the health of your CICS environment.
This session will cover recent enhancements to CICS including
support for deploying and managing shared services such as TCP/
IP connectivity, web services resources and Java runtimes as part
of a Platform. Customers using workload management will discover
how Application context information can now assist with dynamic
routing. We will also describe the new threshold policies.

System Events
§ Capture events when:
– DB2 connection status changes
– FILE enable status changes
– FILE open status changes
– CICS message is issued
– Unhandled transaction abends
– Current active tasks for a TRANCLASS goes above or below a
certain percentage of MAXACTIVE
– Current active task in a region goes above or below a certain
percentage of MAXTASKs

27. System Event Examples
! Generate an alert whenever a connection from CICS to DB2 is
no longer in Connected status
! Emit events for all transaction classes when the number of
transactions in the tranclass goes below 50%, to understand
which tranclasses are least used (write the events to a TS
queue, or monitor by sending to IBM business monitor)
! Collect events about any changes in the open status of the
‘CUSTOMER’ file, to ensure these happen within the approved
batch windows

! Single point of control for CICS resource definitions including
• Create, Update, Delete, Copy, Replicate
! Provides the ability to “change manage” definitional change
through the various user environments (e.g. Development, Test,
Production)
! Provides audit, back-out and change authorization capabilities
