Information regarding potential future products is intended to outline our general product
direction and it should not be relied on in making a purchasing decision.

Performance is based on measurements and projections using standard IBM
benchmarks in a controlled environment. The actual throughput or performance that any
user will experience will vary depending upon many factors, including considerations
such as the amount of multiprogramming in the user’s job stream, the I/O configuration,
the storage configuration, and the workload processed. Therefore, no assurance can be
given that an individual user will achieve results similar to those stated here.

Mobile scenario
Connect directly to CICS from Worklight using end-to-end JSON
A B C
DFHLS2JS to generate the
JSON artefacts for the target
CICS service.
Mobile developer uses
JSON schema to build a
Worklight adapter.
Frontend mobile developer calls
the Worklight adapter which calls
the service hosted in CICS.

Liberty profile scenario
WebSphere Application Server Liberty profile
Introduced in CICS TS V5.1
Light weight web container
• Provides Servlets and JSPs support for CICS
• Runs in a JVM server in the CICS address space
• Access to CICS functionality through the JCICS API
Existing web
interfaces
developed using
JSPs and
Servlets can be
easily moved into
CICS
Direct access to
DB2, providing
application
developers with
two routes to the
data
CICS TS
JVM server
Liberty profile
Web
App
JDBC DB2
CICS
Resources

Liberty profile scenario
Port JSP, servlet or JAX-RS presentation code into CICS
A B C
Modify application data logic to
make JCICS API calls or direct
JDBC calls, if required
Package application into a EBA
for deployment into CICS
Liberty
Install CICS application into CICS
Liberty Server and enable using
the CICS Explorer

CICS
V5.1
Trigger: Action:
TDQ
Prog. Link

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

SAML security scenario
A B C
Client requests SAML assertion
from Tivoli Federated Identity
Manager or Datapower
CICS COBOL application extracts
SAML containers from DFHSAML
channel
The application can add additional
attributes to the assertion for
downstream components

CICS TS
Cloud application multi-version scenario
Rolling back to an
older version of an
application is a
simple operation -
mark the version as
‘unavailable”
Versioning provides
support for the
“major.minor.micro”
system
Transition to newer (or older) version
Version 1.0.0
Version 1.0.1
Version 1.2.0
Version 2.0.0
Install, enable,
make available
make
unavailable

Cloud application multi-version scenario
A bug has been found and an urgent fix is required immediately
A B C
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

Example of Java 8 and z13 benefits
Statement of Direction: IBM intends that a future release of IBM CICS Transaction
Server for z/OS will support 64-bit SDK for z/OS, Java Technology Edition, Version 8
(Java 8). This support will enable the use of new facilities delivered by IBM z13 which
are exploited by Java 8, including 'Single Instruction Multiple Data' (SIMD)
instructions for vector operations and simultaneous multithreading (SMT).

Web service
optimizations
Performance
improvements
Enhanced insight
Additional security
options
Performance optimizations, enhanced metrics, and additional security
Flow control to prevent HTTP requests flooding a CICS region
TCP/IP can efficiently route new work elsewhere
Pipeline processing of HTTP requests has been improved
Removes the need for an intermediate web attach task (CWXN
transaction) for most types of SOAP and JSON based HTTP
CICS Web services, reducing CPU and memory overhead
The optimization can also be used for inbound HTTPS requests
using AT-TLS for SSL support (by configuring TCPIPSERVICEs
as AT-TLS aware)
Even for HTTPS using CICS-provided SSL, improvements have
been made by removing a number of TCB switches
New non-Java JSON processing infrastructure
Provides greater throughput with less overall CPU

HTTP
Requests
Long running task on its own
TCB. Must not be blocked by
an individual request.
If CICS SSL* OR
Web analyser program OR
Static response OR
Not enough data => CWXN
Gets tran ID and user ID from
URIMAP and/or AT-TLS
Start application transaction
with the specific tranid and
userid
Process next piece of work
SOLS
Synchronously receive
body data and pass to
next step in application
Application processing
run as before
CWXN
Only run when
unable to
establish
context
in SOLS
User Transaction
i.e. CWBA, CPIH
* But using AT-TLS for
secure connection will
also bypass CWXN

Web service
optimizations
Performance
improvements
Enhanced insight
Additional security
options
Internal performance improvements in many other areas:
30 additional SPI commands have been made threadsafe
Exploits some of the hardware instructions introduced with IBM
z9, such as STCKF
Cache alignment for key CICS control blocks
Reduced lock contention within monitoring algorithms
Improvements to MRO session management algorithms
Noticeable improvements
CICS trace facility
CICS monitoring facility
MRO connections with high session counts

Web service
optimizations
Performance
improvements
Enhanced insight
Additional security
options
Transaction tracking supports transactions started by the
CICS-WebSphere MQ bridge
Transaction tracking identifies relationships between application
tasks as they flow across CICS systems
Aids problem determination, reporting and auditing
Metrics have been added to global CICS statistics
Transaction CPU time measurements captured without needing
CICS monitoring to be active - allows greater insight into CPU
resource usage without the overhead of collecting and
processing SMF 110 monitoring records

Web service
optimizations
Performance
improvements
Enhanced insight
Additional security
options
Support for the Enhanced Password Algorithm
Uses RACF APAR OA43999 for stronger encryption
Enhanced support for Kerberos
EXEC CICS SIGNON TOKEN command: avoids need to flow a
password – applications can validate a Kerberos security token
and associate a new user ID with the terminal
New EXEC CICS REQUEST PASSTICKET API
can be used for outbound requests from the current task where
basic authentication is required – requests an external security
manager, such as RACF, to build a PassTicket
Further off-load of authentication requests to open TCBs –
reduces contention on RO TCB
