In this article the performance costs when linking to a Java application in a Liberty JVM server are compared to the costs of using an OSGi JVM server or a standard CICS COBOL program. Continue reading Link to Liberty in CICS TS V5.3 – what’s the performance cost?
CICS APAR PI72104 is now available and extends support for the DFHDPLOY utility to support PERFORM PIPELINE SCAN, SET PROGRAM PHASEIN and SET PROGRAM NEWCOPY operations against CICS regions in a CICSplex Continue reading DFHDPLOY support for PROGRAM and PIPELINE
The IBM Redbooks video course – Developing a RESTful Web application for Liberty in CICS provides a step-by-step guide for creating a simple RESTful Java application, then deploying it into WebSphere Liberty running in CICS Transaction Server for z/OS (CICS TS) V5. Its primarily aimed at Java application developers who want to get started with... Continue reading An IBM Redbooks video course – Developing a RESTful Web application for Liberty in CICS
JCICS provides a simple object hierarchy for accessing the CICS API from Java, and is similar to the EXEC CICS command API supported for other languages such as COBOL or assembler. Unlike other CICS high level languages, no translation step is necessary during compilation as the underlying EXEC CICS calls are dynamically generated via the...

Using TRANCLASS to control workload can improve the performance of asynchronous applications even further. Continue reading Using TRANCLASS with the CICS asynchronous API
CICS TS V5.2 enhanced the Liberty JVM server to support the Java Transaction API (JTA) . This enables Java EE applications deployed into CICS to coordinate transactional updates to CICS resources, such as VSAM files, together with XA resources such as a remote DB2 database using a JDBC type 4 driver Continue reading Using Java Transactions in CICS Liberty to coordinate JDBC updates
This blog shows you how to improve response times with TIMEOUT and NOSUSPEND in asynchronous applications using CICS APIs. Continue reading Improving response times with TIMEOUT and NOSUSPEND in asynchronous applications
Introducing the new FETCH ANY command for the CICS Asynchronous API, which allows parent tasks to fetch the results of any completed child task. Continue reading New FETCH ANY command for the CICS Asynchronous API
Learn about the 'uncaptured wait time' in CICS and how things that can cause 'uncaptured wait time' are decreasing. Continue reading Ever wonder why CICS total suspend time is greater than the sum of the component suspend times?
In this article we'll look at how you can prepare your Java EE application, running in a Liberty JVM server, to be invoked from any CICS program. Continue reading Link to Liberty now available in CICS TS V5.3
