Driving Operational Efficiencies – Greater Capacity

Greater horizontal and vertical scaling

• Greater single region scalability by doubling the

MAXTASK limit to 2,000

• Greater usage of 64-bit storage and reduced usage of

24-bit storage

• Greater application parallelism through threadsafe

API and SPI extensions

• Greater system parallelism through optimized Task

Control Block (TCB) usage

• Greater Java performance improvements from 64-bit

Java 7 support

• Greater access to 64-bit application storage when

using Assembler programs

New and improved capabilities provide…


Driving Operational Efficiencies – Managed Operations

Control critical resource thresholds with policies

• Create policies to deliver automated control over

critical system resources

• Set data access thresholds on SQL or file access

requests by a user task

• Set program loop thresholds on EXEC LINK requests

by a user task

• Set storage request thresholds on storage used or

GETMAIN requests

• Set CPU time thresholds on the amount of processor

time used by a user task

• Manage policy breaches by issuing messages,

abending tasks, or creating events

Now you can…


Managed Operation - Policies

� Policies consist of a:

– Threshold condition to monitor resource consumption

– Storage, CPU and Elapsed Time, File/DB2 SQL and TSQ access, Prog.

Link (invoke application included) , Start, TDQ, Syncpoint

� Action to take when threshold is exceeded

– Issue message

– Emit an event

– Abend the offending task

� Policy scope

– Operation, Application, Platform or CICS Region

https://www.ibm.com/support/knowledgecenter/en/SSGMCP_5.3.0/com.ibm.cics.core.help/concepts/policy_th

resholds.html

Introduced by CICS TS 5.2


Policy Scenario

Define a policy to trigger an event when an application consumes too

much total elapsed CPU time

A B C

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

Step 1 Step 2 Step 3


CICS TS v5 and Security

� Web Service Security – SAML Support

• SAML Feature Pack integrated into CICS TS 5.2 or above

– Linkable interface program DFHSAML

Modern Interfaces – Liberty Profile Web Container

� New Java web container is built on WebSphere Application Server Liberty profile technology

• Liberty is a lightweight, composable, ‘profile’ of WebSphere Application

Server

– Provides a fast and lightweight Java web container

• Provides “off the shelf” Web-server capabilities (JSPs and Servlets)

• Provides potential to re-use even more WebSphere technology in CICS.

• JSP and Web servlets have direct, local, access to CICS data and resources.

• Servlets can take advantage of existing CICS OSGi applications to provide a Dynamic Web front end


What is the CICS TS Liberty Profile

• Standard Java APIs (Servlet, JSP, JDBC)

• Supports much of the Liberty Profile

• Can use the JCICS API to link a program in any language


Java Batch in CICS

� Although CICS is primarily an OLTP – we now offer “Batch Applications for the Java Platform (JSR-352)”

• Capability is provided by two Liberty features

– The batch-1.0 feature enables the use of the JSR-352 programming model

– The batchManagement-1.0 feature provides:

� A REST interface for rempte job submission

� The batchManager command-line utility

� Job logging support

� Multiple server support by using JMS

• WebSphere Developer Tools (WDT) enable to create application and

compose jobs using Job Specification Language (JSL), test and deploy

application in local or remote Liberty server

New cloud and DevOps support to automate CICS deployments

On premise pattern based cloud deployment


Increasing service agility - First-class platforms

Create agile service delivery platforms

• Easily deploy applications onto platforms

• Different platforms can have different policies for

the same application

• “How much CPU has this platform consumed?”

• Group new and existing regions as platforms for rapid

application deployments

• Increase flexibility, by decoupling applications from

the underlying CICS region topology

• Increase reliability through automatic resource

deployment and validation

• De-provision resources when requested, without

requiring any interaction from a system administrator

• Deploy applications to started regions within a

platform, without requiring any interaction from a

system administrator

• Dynamically manage platforms by applying policies

during runtime

By defining a platform you can… Greater control through platforms…

DevOps - Automated builds

� The Process


Automated builds

� CICS Build Toolkit provides a command-line interface for automating the building of CICS projects

• CICS cloud applications and bundles, and OSGi Java components,

automatically built from source code

• Variable substitution to facilitate the deployment of the same application to different environments (e..g. development, quality assurance and production)

• Supported on z/OS, Linux and Microsoft Windows

� Can be used in continuous integration environment – a build script can automatically run when developers make updates to their application to

• Check out the latest application version from source control along with its dependencies

• Call the CICS Build Toolkit to build the projects that form the application

• Copy the built projects to a suitable location, such as an artifact repository or a staging area on zFS


Scripted deployments

� DFHDPLOY is a batch utility to support automated provisioning of

• CICS bundles

• OSGi bundles within CICS bundles

• CICS applications

� Can be used to

• Deploy CICS bundles and CICS applications

• Set the desired stat

– e.g. “enabled” or “available”

• Undeploy and remove bundles and applications


DFHDPLOY Example

� Example JCL to replace an existing bundle WEBSITE


Microservices Definitions

An engineering approach focused on decomposing an application into single-function modules with well defined interfaces which are independently deployed and operated by small teams who own the entire lifecycle of the service.

Microservices accelerate delivery by minimizing communication and coordination between people while reducing the scope and risk of change.


CICS Microservices Scenarios


� The IBM z/OS Provisioning Toolkit v1.0 is a simple command line utility for a rapid provisioning of z/OS development environments

� System programmers can easily manage the provisioning process by preconfiguring the environments, control developer access through z/OS security, and set appropriates provisioning limit

� Application developers can provision and de-provision z/OS applications in minutes, without requiring any z/OS specific administration skills

� The toolkit is fully supported and available to all z/OS v2 clients at no additional charge

• Manage the containers that

are provisioned

• Using simple commands,

developers can stop and

restart their containers or

just remove them completely

• The number of containers is

limited by the Operation
