Installation
 Radically Simplified Packaging and Installation
– Full function, simple, single package install
– Developer Operating Systems contain Toolkit and Server
• Total size approx. 1.3 GB
– Server Operating Systems contain only server
 Other changes
– Full entitlement to MQ remains
– MQ no longer packaged
• Default queue manager for IB node for backwards
compatibility
 Built-in Unit Test Environment
– Developer tools have built-in unit test server
• Fixed name of TESTNODE_<userid>
– Started and stopped with tools
– Can still test / deploy to manually created local and remote servers 4
Single install package
for server and toolkit.
Simple unzip on unix.
Local integration node and
server automatically created
when you start toolkit.

• Connect to local or remote
Integration Nodes using toolkit
• Configure bar file properties.
• Deploy bar files

• iib help, iib tools, etc
• Remote administration commands
need to point at the integration
node’s administration port instead of
queue manager.
Integration API
• Java interface for administering IIB
through Java code.
REST API
• Administer IIB resources using
operations defined on a REST
model.
6
WEB UI
• Primary graphical means of
administering IIB.
• Many new features in V10.
• Manage Integration
Servers
• Define policy
• Create configurable
service
• View Statistics
• Workload Management

Loopback Request Node
• The LoopBack Request node provides a way for IIB
message flow authors to invoke synchronous CRUD
operations to external systems using LoopBack
Connectors.
• LoopBack provides numerous connectors to access
enterprise and other backend data systems such as:
• NoSQL databases.
• Relational databases.

NEW ! New LoopBack Request node provides a
way for IIB message flows to invoke
synchronous CRUD operations to external
systems using LoopBack Connectors.
LoopBack is an open source Node.js
framework that can be extended by
downloading and installing connectors from
a large open source catalog using the ‘npm’
tool.
LoopBack provides connectors for:
• NoSQL databases e.g. MongoDB, IBM
Cloudant
• Relational databases e.g. PostgreSQL,
MySQL
• Other backend services e.g. REST,
SOAP

BAR files contain
configurable properties which
allow you to deploy your
applications from your QA
system to Production.
Web UI
Message node properties

Workload management
properties are configurable.

Deployment
14
When a REST API is deployed, the Swagger
document for that REST API is automatically
made available over HTTP from the same
server and port that the REST API is hosted in.
The deployed Swagger document is
automatically updated to reflect the server, port,
and HTTP/HTTPS details for the deployed
REST API. You do not have to update it with the
correct details before deployment.
The REST APIs can be pushed to API
Connect where you can secure them,
define Service Level Agreements and
examine visual analytics data.

How many Integration Servers should I have?
How many Additional Instances should I add?
Additional Instances
• Results in more processing threads
• Low(er) memory requirement
• Thread level separation
• Can share data between threads
• Scales across multiple servers
Integration Servers
• Results in a new process/address-space
• Increased memory requirement
• Multiple threads including management
• Operational simplicity
• Gives process level separation
• Scales across multiple servers
Recommended Usage
• Check resource constraints on system
• How much memory available?
• How many CPUs?
• Start low (1 server, No additional instances)
• Group applications in a single integration server
• Assign heavy resource users to their own integration server
• Increment integration servers and additional instances one at a time
• Keep checking memory and CPU on machine
• Don’t assume configuration will work the same on different machines
• Different memory and number of CPUs 15
Deployment
Considerations Deployment
How many copies of a
message flow do I need ?
Each message flow is different…..
Each will use certain different level of resources
(CPU, memory, I/O) and have a particular
performance profile
In deciding number of copies to run need to know
1. Availability Requirements
2. Target throughput (messages/second) rate
3. Target response time
Number of copies of each message flow needed will
vary.
So do not decide the same number of copies are
sufficient in all cases.
Ultimately need to
balance resource
manageability &
availability.

Workload management policy offers
dynamic control over:
• Message rate limits.
• Additional instances.
• Commit count & commit interval.
• Automatic restart in case of
unresponsive message flow.

Supported Migration Paths
You can migrate to IBM Integration Bus Version 10.0 from the following previous versions:
• WebSphere® Message Broker Version 7.0.0.5
• WebSphere Message Broker Version 8.0
• IBM Integration Bus Version 9.0
36
Migration
Co-existence: IIB V10 can co-exist with IIB V9, WMB V8 and V7.
Windows :
• Multiple instances of each of the versions (but different fixpacks) can be installed on the same system.
UNIX and z/OS :
• Multiple instances of each of the versions and fixpacks can be installed on the same system.
Ensure correct mqsiprofile is sourced before starting the Integration nodes to pick up the correct versions.
Multiple versions of IIB Toolkit can be installed on the same machine
• You can not use IIB V10 Toolkit to connect to a V9 broker or vice versa

39
Migration
Migration Options
In-place migration:
• Migrates existing broker and its components immediately to V10
• Should be performed on the same system where broker exists
• Requires stopping the broker / integration node
• Requires running the command: mqsimigratecomponents
• Provides –t option to roll back to previous state
Parallel migration:
• Provides ability to migrate on same or a different system Does
not overlap with the existing broker, so no need to stop the broker
• Create new Integration node and deploy artifacts to it
• Requires the Integration node / server properties and
Administration security to be reconfigured on the newly created
components

• Capable of handling a wider range of failures
• Failover historically rather slow, but some HA

• Most resilient and best performing systems are those that are:
• Loosely coupled and have parallel execution (threads and processes)
• Implications for your message flow design will depend on the systems that IIB interacts with
• Vital to conduct performance testing before production in production like environment
• Gives time to evaluate and refactor code if needed
• Top Tips
• Always ensure your environment is reproducible
• Treat DR and HA separate
• Ensure regular backups
• Encourage developers to create message flows that enables operational tweaks to be made
• Schedule regular maintenance windows
