IBM MQ for z/OS GA: 17 June 2016
Roll-Up of Continuous Delivery items shipped
via APAR in MQ V8, eg Capped Expiry, JMS
for IMS, channel connection audit sample
Plus significant new capabilities
Following slides cover:
• Pageset Statistics (and stats formatting)
• Additional Active Logs
• Updated Unicode conversion support
• z/OSMF workflows for simplified
provisioning

z/OS SMF statistics for
Pageset usage
New SMF information
Capacity planning: e.g. how much is my
pageset utilization increasing?
Problem resolution: e.g. why are private
messages slow?
System management: e.g. which pageset
should I move into a different buffer pool?
This allows you to see early indicators of
pageset storage shortage
Same data as returned by the DISPLAY USAGE
TYPE(PAGESET) command
SMF makes it easier for automation
tools to analyze

Sample z/OS Management
Facility Workflows
z/OSMF provides services to help customers
rapidly provision/de-provision z/OS middleware
Including MQ, DB2, CICS, IMS, WAS
Workflows can be implemented to automate
tasks
Self-service/click of a button
Rapidly stand-up/down MQ resources for
development/test purposes
Help to address future z/OS skills shortage
Updated for “IBM Cloud Provisioning and
Management for z/OS” in V9.0.1

16
IBM z/OS Provisioning
Toolkit (zospt)
A simple USS utility for z/OS V2
Run from the command line (“Docker-like”)
zospt run mq
Used to rapidly provision and de-provision
middleware environments
Builds on the z/OSMF workflows to manage the
lifecycle of the middleware
CICS and MQ to start with, other middleware plan to
follow
For more info on zospt, see and download:
https://developer.ibm.com/mainframe/products/zospt/
For Provisioning CICS and MQ using zospt, see
articles at:
https://developer.ibm.com/mainframe/category/zos-pt/

IBM MQ Advanced Message
Security – Key Points
Provides additional security to that provided by
base MQ
End-to-end security, message level protection
A security policy defines what protection should be
applied to messages
AMS intercepts messages at “endpoints” and applies the
policy
Asymmetric cryptography used to protect each
message
Integrity policies prove message origin, content not
changed, digitally signed
Privacy policies as per integrity plus each message
encrypted with unique key
Confidentiality policy: encryption, but no signing

Comparing SSL with AMS
V9.0.0 Confidential

Comparing SSL with AMS
V9.0.1 Confidential

Compare V8 Privacy with
V901 Confidential

Use case:
Streaming 10KB Messages
Consider for QRep movement of sensitive data,
where SSL not needed for authentication
AMS is equivalent cost to SSL.
Both AMS and SSL show diminishing returns as
key negotiation period is increased.
AMS encryption / decryption costs are incurred
by the application address space.

Streaming 1MB Messages
With similar amounts of data flowing between
key negotiations, AMS Confidential is able to
demonstrate a reduction of 18% on the
equivalent SSL measurement.
AMS Confidential shows similar costs in the QM
and CHIN address spaces to the ‘no protection’
option but an increase in the application address
spaces.
SSL shows an increase in the CHIN address
spaces compared with the ‘no protection’ and
AMS Confidential measurements.

The MQ Service Provider
Free of charge z/OS Connect service provider
that allows existing services that are fronted by
MQ to be accessed via a RESTful front end
Both z/OS Connect V1 and zCEE supported
Same MQ capabilities in both versions
Client applications need have no knowledge of
MQ

Service types
Each URL in z/OS Connect maps to a service
With the MQ Service Provider there are two
different types of service
Two way services
One way services
A two way service provides request/reply
messaging:
1. Client issues HTTP POST with some
payload (JSON)
2. MQ Service Provider sends payload
(optional transformation) to one MQ queue
3. Back end application processes payload
and puts response on reply queue
4. MQ Service Provider gets response
(optional transformation) and sends it to
client as the body of the HTTP POST
response
A one way service exposes standard MQ verbs
against a single destination
Allows more advanced interactions with MQ
HTTP POST MQPUT Queue and Topic
HTTP DELETE MQGET Queue
HTTP GET MQGET
(Browse)
Queue

Example two-way service
Insurance quote service which takes a request
from an MQ queue and sends a response to
another queue
COBOL request
COBOL response
So COBOL -> JSON conversion needed using
built in tooling, zCEE BAQLS2JS utility

35
MQ support for the zCEE API Editor
• Allows RESTful APIs to be built on top of a
service, such as one provided by the MQ
service provider
• Takes in a service archive file
(SAR) which describes a service
• Generates an API archive file
(AAR) which describes an API
• For MQ the SAR is generated by
the zCEE BAQLS2JS utility
Use query and URL
parameters in your API
API verbs map to
MQ operations
Define data
transformations on
request and response
API projects can be imported
and exported easily between
developers

Example two-way service –
request

Example two-way service –
response

Availability
MQ Service Provider for z/OS Connect
Provided in USS component of MQ V9.0.1
Supported with MQ 8 and later queue
managers, in bindings mode.
Also available on Fix Central
In case you don’t have the latest version of
MQ available
Only contains the MQ Service Provider function.
You need to provide z/OS Connect (V1 or V2)
Code consists of a jar file, and a Liberty feature
manifest

The CICS JMS Story
Support for MQ JMS in CICS 5.3 and 5.2 OSGi
environments
Works with MQ 7.1 and later
Depending on environment some APARs
needed
Since 1Q 2015
Support for MQ JMS in CICS 5.3 Liberty
environments
JMS from MQ V9.0.1 – available 4Q 2016
CICS 5.3 + PTFs
New!

What is CICS Liberty JVM
Server?
For a number of CICS release support has been
provided for running Liberty inside the CICS
address space
Only a subset of JEE capability supported
Integration provided with native CICS
capabilities
In some cases slight adjustments to
programming model/the way things work
CICS V5.3 +PI58375 changes things, two sorts
of CICS Liberty introduced
Liberty Standard
Liberty Integrated
Liberty Standard:
FULL Liberty support. No CICS integration
Perfect for ‘lift and shift’
Liberty Integrated:
Same capability as provided before, subset
of JEE integrated with CICS capabilities
Perfect when needing to integrate JEE with
CICS transactions
Subset continuing to expand

What does this mean with
MQ?
Allow CICS Liberty to use MQ resource adapter
Just like normal Liberty
Run existing Liberty messaging apps (eg MDBs)
inside CICS
Connections to MQ supported using either client
or bindings mode
Some restrictions depending on
environment
Prereqs CICS V5.3 +PI58375 + MQ 9.0.1 RA

CICS Liberty Standard JMS
Support
Bindings (RRS) and/or client (XA) connections
supported
Bindings not allowed when there is a CICS MQ
adaptor connection (TRUE) to same MQ

CICS Liberty Integrated
JMS Support
Client (XA) connections only

Aqua
https://developer.ibm.com/mainframe/products/
downloads/eclipse-tools/

MQ Console architecture
Since V901, MQ embeds a liberty server
constrained to serve the MQ Console app and a
new admin REST API
MQ Console server can be used to administer
local queue managers running the same version
of MQ code.
