MQ v8.0 & IBM Integration Bus v10.0


Understanding the IBM Integration Bus – Cont’d

What are the main components of IIB/WMB?

The 3 main components in IIB/WMB are given below:• Runtime - The broker runtime is the main processing component to which

development artifacts are deployed.

• Development - The Toolkit is used for development of message flows and other development artifacts.

• Administration - Message Broker Explorer is an administration tool used to perform deploys, create brokers or new execution groups, and enable flow monitoring. WMB V8 provides a WebUI tool to view the broker runtime or resources deployed in a browser.

Does IIB/WMB require a database to function?

From Message Broker v7.0 onwards, there is no database pre-requisite, the product does not require a database for any internal function.

Co-existence of MQ v8.0 and IIB v10.0 – Cont’d

MQ v8.0:

• MQ 8.0 supports queue managers on Linux 64-bit platforms and does not support queue managers any longer on the Linux x86 32-bit platform.

• This means that you cannot install the MQ 8.0 server code on Linux x86 32-bit, although you can install the MQ 8.0 client code, which is supported in both Linux 64-bit and 32-bit platforms

• A 7.0, 7.1, 7.5 and 8.0 client can connect to all queue managers, non-version 7, as well as version 7.0, 7.1, 7.5 and 8.0

• A 7.0, 7.1, 7.5 and 8.0 queue manager can interact with all clients, non-version 7, as well as version 7.0, 7.1, and 8.0

10




IIB v10.0:

• IBM Integration Bus Version 10.0 can co-exist with previous versions as follows:• IIB v9

• WebSphere Message Broker Version 8.0

• WebSphere Message Broker Version 7.0.

• Multiple versions of IIB Toolkit can be installed on the same machine.

• You can not use IIB v10.0 Toolkit to connect to a V9 broker or vice versa

Note:• Message Broker v7.0.0.5, v8.0 and IIB v9.0 can migrate to IIB v10.0

11




• On distributed systems, WebSphere MQ is no longer a prerequisite for using IBM Integration Bus Version 10, which means that you can develop and deploy applications with IBM Integration Bus without needing WebSphere MQ.

• However, some IBM Integration Bus features require access to WebSphere MQ, including the MQ nodes and the event-driven processing nodes that are used for aggregation and timeout flows, message collections, and message sequences.

• For such instances the following MQ versions are supported for IIB v10.0:

Product Roadmap

MQ:



Product Roadmap

IIB:



IIB v10.0 Architecture

• IIB processes messages in two ways: message routing and message transformation



User Roles & Environments – IIB v10.0

• Typically the Application Developer will not be aware of the environment to which message flows will be deployed; this is the responsibility of the broker administrator.

• Similarly, the broker administrator may not be aware of the exact message flow logic supplied by the application developer.

• IIB provides tools and techniques to enable IIB applications to easily flow between the application developer and administrator



MQ v8.0 Installation Procedure

• WebSphere MQ requires a user ID of the name mqm, with a primary group of mqm.

• The mqm user ID owns the directories and files that contain the resources associated with the product

File System Permissions for WebSphere MQ Directories:

• Users in the mqm group have write access to these directories and files.• The files and directories in this category are only accessible to WebSphere MQ

Administrators (members of the 'mqm' group) and the WebSphere MQ Queue Manager processes.• -rwxrwx--- mqm:mqm (UNIX and Linux)

• The executables under /usr/mqm or /opt/mqm and they are owned by "root"

• The data of the queue managers under /var/mqm, which is owned by "mqm“

Note:• Please do NOT change the file ownership and permissions for the executable’s in

/usr/mqm or /opt/mqm17



MQ v8.0 Installation Procedure – Cont’d

• i386 is the name of the 32-bit Operating System • X86_64 is the name of the 64-bit Operating System

MQ Config Script:

• IBM provides the mqconfig script to simplify the task of configuring your system.

• If your environment is running with MQ v8.0, then MQ Config script is included in the binaries.

• For other MQ versions, MQ Config script should be downloaded separately

18




• If you do not configure your operating system parameters properly, your IBM MQ queue managers may run out of system resources while handling your production workload.

• Depending on the resource which was exhausted, MQ may return an error to the application (like MQRC_RESOURCE_PROBLEM, reason code 2012), write a message to its error logs, create FDC files in the /var/mqm/errors directory, or even terminate

Note: • The mqconfig script compares your system settings against these IBM default limits,

which should be sufficient for many systems.

• However, even these settings may be insufficient if you have a very busy system with high production volumes, or if your system is also hosting other products like databases or application servers.

19




MQ Config Script – Cont’d:

20




MQ Config Script – Cont’d:

Note:• Do not assume that an "all clear" report from mqconfig means you cannot run out

of resources.

• Run the mqconfig script when your system is processing its peak volume to ensure that the actual resource usage, shown as a percentage, is not excessively high.

• The mqconfig script will verify all of the kernel parameters for MQ and check the resource limits and shell settings for the current user

21




22




• Login as userid root, in order to install the code• tar -xvf WSMQ_8.0_IFR_TRIAL_LNX_ON_X86_64_.tar

23




• Accept the WebSphere MQ license agreement by entering the following command:• ./mqlicense.sh -accept

24




• The setmqinst command to change the installation description of an installation, or to set or unset an installation as the primary installation

• setmqinst -i -p InstallationPath• setmqinst -i -n InstName

25




Note: • There is a global file in /etc (from MQ v7.1) which provides information on the

additional installations of MQ in the machine, the path is given as below:• /etc/opt/mqm/mqinst.ini

26




The MQ installation process is complete upon the following screen:

IIB v10.0 Installation Procedure on Linux

• IBM Integration Bus can be installed on UNIX, either for use by a single user or for use by multiple users which is the shared.

Single User Installation:

• As a user without administrative rights, you can create a single-user installation of IBM Integration Bus in your home directory.

• This single-user installation is then accessible only by your user ID

Shared Installation:

• As a user with administrative rights, you can create a shared installation of IBM Integration Bus.

• To authorize any users of the computer to access the shared installation of IBM Integration Bus, add the users to the mqbrkrs group by using the security facilities that are provided by your operating system.

28



IIB v10.0 Installation Procedure on Linux – Cont’d

Single User Installation Procedure:

• log in with your personal user ID to install IIB v10.0 as a single user.

• Single User ID: mqsi

• Login as a mqsi user ID – this is a personal ID which is not part of mqbrkrs group

• tar -xvf iib-10.0.910.2.tar

• /iib accept license silently

29




Single User Installation Procedure – Cont’d:

Note:•What happens if we try to attempt shared installation by using non root user ID?

Single User installation and Working directories for IIB v10:

Installation Directory: install dir/iib-10.0.0.n where install dir is the directory where you unpacked the installation image. In this case, /tmp/MQDUMP

Working Directory: This directory is the work path for IIB, and stores the IIB configuration files. In this case, /home/mqsi

30





Setting up a Command Environment for Single User Installation:

• Runtime components, and commands that administer runtime components, must be run from a command environment.

• This command environment is initialized by running the “mqsiprofile” command

• On Linux or UNIX systems: Locate and run the mqsiprofile.sh script in the directory in which you installed the appropriate product

• Install dir/server/bin/mqsiprofile

31





• MQSI list: Use the “mqsilist” command to list installed integration nodes and their associated resources

32




Shared User Installation Procedure:

• As we mentioned earlier, root user can only install the shared user installation type. Hence log in as a root.

• Installation Directory: /opt/IIB10/. Place the binaries in this path and untar.

• Working Directory: /var/mqsi

33




Shared User Installation Procedure – Cont’d:

mqsi Profile Configuration:

Creating an integration node using the command lines:

• Use the mqsicreatebroker command to create an integration node.

• mqsicreatebroker <BROKERNAME> -q <QUEUEMANAGER NAME>

• mqsicreatebroker <BROKERNAME>

34





Creation of Integration Node Using the below Command:

• mqsicreatebroker <BROKERNAME> -q <QUEUEMANAGER NAME>

• Validation of Integration node:• Stop the Integration Node• Stop the Queue Manager• Without starting Queue Manager, try to start the Integration node.• It won't start as expected. Restart the Queue Manager and try to start

the Integration node. 35





Creation of Integration Node Using the below Command – Cont’d:

36






Note:• When the integration node is created by using –q flag, the queue manager should

be in running state for the integration node to work.

37






• mqsicreatebroker <BROKERNAME>

Note:• Normally in all the business environments IIB will be configured as a Shared User

Installation. Single user Installation is enhanced option in IIB v10.

• Before using the Single User Installation we have to check with the application team or customer. If it is a business demand then setup with the Single User installation.

38




• Single User Installation observations: • IIB administration ID should not be a part of mqbrkrs group.• Individual ID can administrate the IIB completely.

• Shared User Installation Observations: • IIB administration ID should be a part of mqbrkrs group.• Working Directory will be /var/mqsi

Checking the IIB version – Post Installation:

• mqsiservice -v
