MQ on AWS: PoC of high availability using EFS

Arthur Barr Comments (2) Visits (18186)

Amazon recently declared its Elastic File System (EFS) as ready for production. This enables a shared, networked file system, which (importantly) is replicated between multiple physical data centers (availability zones). On paper, this makes EFS a good candidate for running MQ in a highly available way. In this blog entry, I'll take you through our proof of concept (PoC) of running a single IBM MQ queue manager which can be automatically moved between availability zones in the case of a failure. An EFS... [More]

An Introduction to WebSphere MQ queue manager processes (Version 6)

neekrish Visits (34285)

(Republished old entry after correcting the links to images) Author: Madhukar B V When a queue manager is created, you get a message something like this: Observe that 40 default objects are created when a queue manager is created. An MQ object can be a queue, a channel, a namelist, a listener (in WMQ v6.x), a process, etc. Most of these default objects act as templates for defining queue manager objects. For example, SYSTEM.DEFAULT.LOCAL.QUEUE is used as a template and its attributes are copied when a new local queue is defined using “DEFINE... [More]

OPMODE in MQ V9 CD for z/OS

gwydiontudur Visits (3467)

I recently wrote about how OPMODE works in the Long Term Service (LTS) release of MQ V9 on z/OS, and the differences compared to previous versions of MQ. The operation of OPMODE is quite different again in the Continuous Delivery (CD) releases of MQ V9, and that’s what I want to describe now. So what’s different? From V9, MQ has moved a continuous delivery support model. This means that in addition to the LTS release for installations where only defect fixes are required,... [More]

IBM MQ - Using AWS CloudWatch to monitor queue managers

Mark E Taylor Visits (9436)

In this final(?) blog entry of a series, I'm going to show how you can monitor MQ queue managers using Amazon's CloudWatch service. Previous blog entries The earlier blog entries in this sequence include The basics of using the Go language with MQ Monitoring with Prometheus and Grafana Monitoring with InfluxDB, OpenTSDB and collectd Matthew Whitehead's article on using collectd with Bluemix and there is also a video on the...

Storing and searching MQ error logs in Elasticsearch

Matthew Whitehead Comments (8) Visits (12354)

The Elasticsearch stack is a useful way to store, search and visualise data. If you're not familiar with the ELK stack you may find this introduction useful. It comprises 3 components: Elasticsearch - A distributed search engine based on the Apache Lucene project Logstash - a log collection and processing tool Kibana - a browser based visualisation tool for displaying and searching log data This article assumes that you have installed your own Elasticsearch and Kibana server locally and are...

Basic deployment of MQ on AWS

Arthur Barr Visits (16106)

This blog entry discusses a basic deployment of IBM MQ on Amazon Web Services (AWS). This blog entry assumes basic knowledge of AWS. Background - Immutable infrastructure As discussed in a previous blog entry , there are two main approaches to managing virtual machine software. One approach is to use the base images supplied by your cloud provider (which usually just have the base operating system installed), and then entirely manage the software stack using configuration management software such as Chef, Ansible, Puppet...

Introducing the IBM Message Hub user interface

RichardPilot Visits (6545)

IBM Message Hub has gone GA and is now available on Bluemix. You can find out more about the service here . It's a great way to asynchronously connect applications and services in the cloud. I'll use this blog post to show off the user interface for this service. The Message Hub UI has been designed to give you an at a glance snapshot of your Message Hub instance and is intended to be something simple that can used to view the list of topics including the current status of all deletion operations. You can also create and delete... [More]

MQ support for MQ Light and AMQP 1.0 released in 8.0.0.4

Matthew Whitehead Comments (15) Visits (19640)

Support for MQ Light and AMQP 1.0 clients connecting to MQ queue managers has been released. The support is included in the new MQ 8.0.0.4 fixpack. To install the new AMQP function you will need to install the full version of MQ 8.0.0.4 from Passport Advantage rather than adding fixpack 4 to an existing MQ 8 installation. This is because the AMQP service is a new optional install component which has required updates to the MQ installers. The MQ Advanced for Developers download ( available here ) has also... [More]

Logger enhancements for MQ v9.0.2

MarkWhitlock Visits (5783)

In MQ v9.0.2, we've enhanced linear logging to enable automatic management of log extents and automatic recording of media images, as well as improving the general performance of linear logging scenarios exploiting these capabilities. This addresses some of the most highly voted for RFE's. The decision to choose circular or linear can now be made based primarily upon whether you want media recovery. Now that we've made linear so much easier to administer and brought linear up to a similar performance to circular, these factors cease... [More]
