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.

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).

CICS TS V5.3 open beta : Operational
Efficiency
Performance optimizations, enhanced metrics, and additional security
CICS TS V5.3 open beta delivers optimizations to the CICS Web service
infrastructure
Pipeline processing of HTTP requests has been improved, removing 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

HTTP in CICS TS V5.3 Open Beta

TCB. Must not be blocked by an
individual request.

Internal performance improvements in many other areas:
•Exploits some of the hardware instructions introduced with IBM z9, such
as STCKF
•Cache alignment for key CICS control blocks
•Use of prefetch
•Reduced lock contention within monitoring algorithms
•Improvements to MRO session management algorithms
•Further tuning of internal procedures
Improvements in efficiency give noticeable improvements in the CICS
trace facility, the CICS monitoring facility, and for MRO connections with
high session counts

security options
Transaction tracking identifies
relationships between application tasks
as they flow across CICS systems, and has
been extended to transactions started by the CICS-WebSphere MQ
bridge. This expands the scope of transactions that can use transaction
tracking, to help with problem determination, reporting and auditing
Metrics have been added to global CICS statistics, including transaction
CPU time measurements captured without needing CICS monitoring to
be active - allows greater insight into CPU resource usage of CICS TS
V5.3 open beta regions without the overhead of collecting and
processing SMF 110 monitoring records

security options
New and enhanced security options:
•Support for the Enhanced Password Algorithm implemented in RACF
APAR OA43999 – for stronger encryption
•Enhanced support for Kerberos via 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

CICS TS V5.3 open beta:Cloud with DevOps
Cloud applications and bundles: a
convenient way to package and
manage components, resources,
and dependencies in CICS
CICS TS V5.3 open beta introduces the CICS Build Toolkit
– provides a command-line interface for automating the
building of CICS projects created using CICS Explorer.
CICS cloud applications and bundles, as well as OSGi
Java components, can be automatically built from source
code
Could be called as part of a script to automatically rebuild
an application when a developer makes updates
CICS build toolkit supported on z/OS, Linux and Microsoft
Windows; supports CICS TS V4.1 and later

• DFHDPLOY – new batch utility to support automated provisioning of
CICS bundles, OSGi bundles within CICS bundles, and CICS
applications
• DFHDPLOY commands can be used to deploy CICS bundles and
CICS applications into a desired state, such as ‘enabled’ or ‘available’
as well as undeploy and remove them

requests, named counter requests, and shared temporary storage
requests issued by a CICS task – there are now 14 types of thresholds
against which an action can be triggered
Support for transaction entry points added for CICS cloud applications
(in addition to program and URIMAP entry points already provided) –
scope policies to be specific to a particular transaction ID
Recovery of the application infrastructure enhanced – the available or
unavailable state of an application is automatically recovered across
CICS restarts
