Using the CICS asychronous API enables you to make the most of asynchronous processing in a flexible, supported way - but how does the API's RUN TRANSID command compare to pre-existing alternatives such as START? EXEC CICS RUN TRANSID vs. EXEC CICS START When it comes to starting other transactions, the START command is the nearest existing... Continue reading How does the CICS asynchronous API perform?
The CICS asynchronous API provides a simple, supported way to improve efficiency and reduce response times via asynchronous processing. For system administrators, the API affords a great opportunity to improve performance, and using CICS policy, you can gain even finer control over the the parent and child tasks in your system. CICS policy CICS policy provides a... Continue reading Using CICS policy to restrict the number of asynchronous child tasks
The API enables developers to easily incorporate programming logic that follows a ‘parent-child’ model in their applications. This can be used to create more responsive applications, as it allows for workloads to run concurrently. Continue reading The CICS Asynchronous API in CICS TS V5.4
This article discusses how CICS TS V5.4 utilises the z/OS WLM health API (IWM4HLTH) as a means of controlling the flow of work into a CICS region at startup and shutdown. Continue reading Controlling the flow of work into CICS
What's new in CICS PA V5.4 Overview IBM CICS Transaction Server for z/OS (CICS TS) has evolved to become the world's most powerful mixed language application server. In support of CICS TS, CICS Performance Analyzer (CICS PA) provides the most comprehensive reporting, analysis and visualization for CICS performance data. CICS PA V5.4 provides enhanced reporting and... Continue reading CICS PA V5.4 supports the worlds most powerful mixed language application server
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...
