Current state

The CMCI is a system management interface for use by HTTP client applications such as CICS Explorer It originally provided a single REST API

In CICS TS 54 a new component was added to CMCI called the CMCI JVM server This is a Liberty server which enables additional capability on top of the basic CMCI and has been extended in subsequent releases

CICS TS 54 Multi-factor authentication

CICS TS 55 GraphQL API supporting aggregation and map in CICS Explorer

CICS TS 56 Bundle deployment API for rapid development turnaround

However these extra capabilities are only available in CICSplexes Single regions meanwhile are only able to use the basic CMCI

Group Name DOC ID Month XX 2020 copy 2020 IBM Corporation 10

CICS TS open beta - Developer Experience

A Java developer can use familiar tools to deploy bundles to CICSeven in a standalone CICS region




~ or you could say ~

A system programmer can use multi-factor authenticationand aggregation in CICS Explorer even in a standalone CICS region


New capability mdash in CICS TS open beta

CMCI JVM server can now be used in single region environments to enable all of these capabilities currently only provided for CICSplex

A single CICS region with the CMCI enabled is known as SMSS (System Management Single Server)

New An SMSS with the CMCI JVM server enabled can be referred to as SMSSJ

We have aimed to make SMSSJ more integrated and easier to set up than the existing SMSS support


Demo

Or download the open beta and try it yourself

Documentation - httpswwwibmcomdocsencics-ts61_betatopic=cmci-setting-up-in-single-cics-region


Summary

CMCI JVM server is now available in an SMSS region

SMSSJ is easier to set up than SMSS was previously

Enables

bull simple bundle deployment using MavenGradle plug-ins

bull JCICSX API for rapid development

bull support for MFA (Multi-factor authentication)

bull quick resource analysis with aggregation


CICS policies and the new compound condition system rulesmdash

Jenny HeMaster Inventor Software EngineerCICS DevelopmentHEJENukibmcom


What is a CICS policy A CICS policy has one or more rules each with condition(s) and an action

A CICS policy is a standard and modern method with real time monitoring of the status of CICS region and CICS tasks



When to use CICS policies

Care about excessive storage oramount of API commands by a user task

bull CICS policy task rules monitor resource usage by individual task

bull Action for task rules can be a message a CICS event or abend the task


Care about CICS regionrsquos resourcestatus change

bull CICS policy system rules monitor system resource status

bull Action for system rules can be a message a CICS event or changing zOS WLM open status

bull For AID threshold rule can be rejecting an EXEC CICS request

CICS policy rules monitor the system in real time with no-polling mechanism

What can I monitor onsystem resourcesCICS TS 54bull Bundle available statusbull Bundle enable statusbull DB2 connection statusbull File enable statusbull File open statusbull IPIC connection statusbull MRO connection statusbull Program enable statusbull Messagebull Unhandled transaction

CICS policies vsCICS application events

CICS application events

bull Use capture specifications to filter on application data on selected EXEC CICS API calls

bull Action is a CICS event


CICS policies

bull Use rules to monitor system resource status the amount of resource usage and unusual system states

bull Action can be a message a CICS event abending task changing zOS WLM status or reject EXEC CICS request

CICS system events are deprecated and replaced by CICS policies
