CICS TS V5 : The New CICS Application Lifecycle

You can now package a CICS application into an application bundle to deploy, manage, and monitor it throughout the application lifecycle - as a single entity.

CICS TS V5 : On-demand self service

10

!   On-demand self-service A consumer can unilaterally provision computing capabilities… as needed automatically without requiring human interaction with each service provider.

Because CICS applications are self-contained and self-describing, they can be moved through the lifecycle more quickly and reliably, with less human interaction.

CICS TS V5 : Multi-version applications

11

Multi version applications make it simple to enable and disable new versions of a CICS application, enabling faster, more reliable, and lower risk upgrades.

CICS TS Version 1.0.0

Version 1.0.1

Version 1.2.0

!   On-demand self-service A consumer can unilaterally provision computing capabilities… as needed automatically without requiring human interaction with each service provider.

If you find a bug in a new version of an application, production fixes can now be updated extremely rapidly.

After fixing the bug in the code, repackage it with a new micro

version number

Once installed, switching to a new version of the application is simply a

case of making it “available”

CICS takes care of moving clients to the new version of the

application across all regions within a platform

CICS TS V5 : Defining and Measuring Applications

14

You can now package a CICS application into an application bundle to deploy, manage, and monitor it as a single entity.

•  CICS provides support for monitoring and measuring the resource usage of applications.

•  You can scope the monitoring and measuring at the application level or for particular application operation.

•  You can monitor and measure application resource usage across CICS regions and multiple tasks.

•  You can utilize shared CICS resources (e.g. a program) and attribute usage of that shared resource to the calling application.

CICS TS V5 : Policing Costs and Service Levels

16

Target CPU range.

If CPU enters this range, then issue message. If CPU enters this range, then emit event to dashboard. Restricted. Abend task if CPU enters this range.

Policy Types: •  CPU time •  Storage requests & bytes •  SQL requests •  LINK requests •  FILE requests •  Elapsed time •  TDQ requests & bytes •  TSQ requests & bytes •  START requests •  SYNCPOINT requests

You can now define a policy to trigger an action when an application consumes more resources than it is entitled to, helping to manage critical resources and better control application costs.

CICS TS V5 : Measured Service

17

You can now define a policy to trigger an event when an application consumes too much total elapsed CPU time, warning of additional costs

!   Measured service Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts)

Define the policy thresholds and trigger action that CICS

should take

Associate the policy with the appropriate platform or application and deploy

When the threshold is breached, CICS triggers an event, updating

an operations dashboard

You can now extend your SOA to include RESTful JSON services, enabling CICS to communicate with Mobile servers in the language those servers will use to communicate with Mobile devices.

CICS TS V5 : Broad Network Access

19

!   Broad Network Access Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations).

Worklight adapter.

Frontend mobile developer calls the Worklight adapter which calls

the service hosted in CICS.

Step 1 Step 2 Step 3

You can now use standard CICS SOA enablement tools and technologies to provide Mobile ready interfaces for Mobile application consumption.

Application packaging helps you consolidate onto fewer regions by providing private program definitions

!   Resource Pooling The provider’s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand.
