Co-existance

Version Co-existance

WMB v8.0 can co-exist with v6.1, v7.0 as well as other v8.0 installations

V8.0 installs can be maintained at different FP levels Installation wizard uses a ../v.r.m.f/ in installation path <Root of working directory>/Install.properties

IBM Software Group


Co-existance

Version Co-existance

NO! 32bit and 64bit install of same version on single system Uninstalling a concurrent installation

• <Installation directory>/uninstaller/ uninstaller.exe Removal of earlier versions is not required

IBM Software Group


Co-existance (contd.)

Component Co-existance

Broker Version 8.0, 7.0 and 6.1 all supported on same system Can be migrated from one level to another Component names “must” be unique

Toolkit All versions supported on same system Support for multiple v8 instances on a sing le system Deployable artifacts upward compatible

IBM Software Group


Co-existance (contd.)

Component Co-existance (cont)

MB Explorer (MBX) IS02 must be removed before installing v8 MB Explorer ! Only 1 version can be installed on a single system To upgrade to a later version of MBX…

• Shutdown MQ Explorer• Uninstall current version of MBX• Verify that no files were ‘left behind ’ • Install the new version• Run strmqcfg -i to complete the migration

Migration Considerations Technical changes in Behavior

Applications and Libraries Message Sets Message Maps

Immediate or In-place migration Allows immediate migration of broker components to v8.0 No client configuration changes are needed Must stop broker prior to migration

Parallel Migration Preferred method if the broker can not be stopped for migration Component names must be unique

IBM Software Group


Component Migration - Toolkit Migration of Toolkit resources

Install v8.0 Broker toolkit to a different location from v7.0 or v6.1 Start the toolkit and enter the workspace location of v7.0 or v6.1 when

prompted for a workspace location and click OK From Broker Application Development Perspective, select Window ->

Reset Perspective and ensure that all views and menus are updated for v8.0

Migrate any UDN source projects that were created prior to v8.0 An error is displayed on all projects that require migration

IBM Software Group


Component Migration – Toolkit Importing resources from previous versions

Resources from earlier versions of WebSphere Message Broker such as message flows, message sets, Java™ / PHP projects can be imported into v8.0 toolkit by migrating them or exporting them as a PIF (project interchange file) and importing them into v8.0 toolkit

Migrating Message Flow Projects After an import of resources into v8.0 toolkit, all Message Flow projects

are converted to Message Broker projects Behavior of Message Broker projects is the same as Message Flow

projects

IBM Software Group


Component Migration - Broker Differences between v6.1 and v8.0

Broker in v8.0 does not require a DB. So, DB2, DB2 Runtime client, Derby DB (Windows Platform) are not supplied with WMB v8.0

mqsicreatebroker and mqsichangebroker commands are updated to remove the database specifications

DBInstanceMgr available on Windows to manage DB2 and Derby databases has been removed

Commands that control DBInstanceMgr mqsicreatedb, mqsideletedb and mqsichangedbmgr have been removed

Configuration Manager component is removed and broker security model is implemented using MQ Queues. So commands that control configmgr mqsicreateconfigmgr, mqsideleteconfigmgr, mqsichangeconfigmgr and mqsireportconfigmgr have been removed

Pub/Sub operations are handled by WebSphere MQ. So, UserNameServer component is removed so are the commands associated with UNS (mqsicreateusernameserver, mqsideleteusernameserver and mqsichangeusernameserver)

IBM Software Group


Component Migration – Broker Migrating a v6.1/v7.0 broker to v8.0 – Tasks to do before migration

Backup Message Broker Resources• ODBC files for User DB connections, Configurable Services, Broker toolkit

resources (.msgflow, .mxsd, .java, .php, .esql, .mmap, .bar) Update ODBC Definitions (Linux/Unix platforms)

• Copy the odbc.ini and odbcinst.ini from <InstallDir>/ODBC/unixODBC to a location of your choice

• Ensure that odbc.ini and odbcinst.ini are owned by mqm::mqbrkrs • Set your ODBCINI environment variable point to the odbc.ini file using absolute

path• Set ODBCSYSINI environment variable point to odbcinst.ini using absolute path• Please refer to IC topic for complete details:

Component Migration – Broker In-place (immediate) migration of v6.1 and v7.0 broker to v8.0 (Distributed

platforms)

Remove the broker from the Broker domain in v6.1/v7.0 toolkit Stop all channels connected to the broker Stop the broker using ‘mqsistop’ command Setup v8.0 command environment Run ‘mqsimigratecomponents’ <BrokerName>

IBM Software Group


Component Migration - Broker In-place (immediate) migration of v6.1/v7.0 broker to v8.0 (z/OS)

Stop v7.0 Broker Create a new PDSE Copy all broker JCL files from v8.0 SBIPPROC and SBIPSAMP PDSEs to the new

broker PDSE

• Backup your v7.0 ENVFILE before submitting BIPGEN job from v8.0 component data set

• Customize BIPEDIT file using values defined in v7.0 BIPEDIT file• Copy all the changes you had made to v7.0 BIPBPROF and BIPDSNAO files in

the v8.0 component dataset. Submit BIPGEN to create the ENVFILE Customize and submit BIPMGCMP job Copy the renamed started task JCL file BIPBRKP to the procedures library Start v8.0 broker

IBM Software Group


Component Migration - Broker Parallel migration – Migrating a v7.0 broker to v8.0

Migrating Application Logic • Install WebSphere Message Broker v8.0 (minimum required is the broker

component)• Update your ODBC definitions to v8.0 format (if your message flows access a

DB using ODBC connectivity)• Set up v8.0 command environment• Create a v8.0 broker using mqsicreatebroker command (broker name and

QMGR associated with the broker must be unique)• Start the newly created v8.0 broker• Create the same EGs that you have on your v7.0 broker (using WMB Explorer

or mqsicreateexecutiongroup command)• Deploy message flows and message sets to the v8.0 broker (NOTE: You must

have migrated the toolkit resources before attempting this)• Configure all other relevant properties of the v7.0 broker on v8.0 broker

IBM Software Group


Component Migration - Broker Migrating v7.0 MSCS Broker (Windows)

Install WMB v8.0 onto each node to a new location Stop all channels connected to WMB v7.0 broker From MSCS bring broker resources offline, keep cluster disk and WMQ resources

online on the primary node From a v8.0 command console run

• mqsimigratecomponents <BrokerName> -m Move the broker cluster group to secondary node (Broker resources are still

stopped) From a v8.0 command console run

• mqsimigratecomponents <BrokerName> -m Copy all custom environment settings from the previous environment to v8.0

environment Bring cluster disk and WMQ resources offline Start WebSphere Message Broker cluster group on primary node

IBM Software Group


Component Migration - Broker Migrating a multi-instance broker

Install WMB v8.0 onto each node to a new location Stop all channels connected to WMB v7.0 broker Stop the broker on the standby node Stop the broker on the active node From a v8.0 command console run

• mqsimigratecomponents <BrokerName> -m Copy all custom environment settings from the previous environment to v8.0

environment Start the broker on the active node Start the broker on the standby node

IBM Software Group


Migrating ACLs (v6.1 only) Admin security is disabled by default in v8.0 Since ConfigMgr component is removed, associated commands

mqsicreateconfigmgr, mqsichangeconfigmgr, mqsideleteconfigmgr, mqsireportconfigmgr, mqsicreateaclentry, mqsideleteaclentry and mqsilstaclentry are removed

Post Migration Tasks – Things need to consider Applications that use WebSphere Message Broker API

• Any WMB v6.1 applications that use WMB API from ConfigManagerProxy.jar need to be recompiled with the one supplied from v8.0

Applications that connect to a broker, connection details that are used by the CMP application need to be updated

Record & Replay feature can only be used with WMB v8.0 brokers (can not be used with v6.1 or v7.0 brokers)

Resource & Message Flow accounting statistics XML publication messages are published with an MQMD header which has an MQSTR FORMAT (so the publication message is entirely character data). If an MQ JMS application subscribes to the publication topic and reads the messages, they are now treated as a JMS Text Message (previously it was JMS BytesMessage)

Post Migration

IBM Software Group


Post Migration Tasks – Things need to consider WMB v8.0 ships with ICU v4.8 for date, time and codepage conversions

• Invalid timezones receive a BIP2319 response from the broker• Obsolete timezones (viz. Alpha, Bravo times) are considered invalid• Date and time formatting using the pattern "zzz" might now return a

time zone ID that implicitly represents a time zone and offset from GMT rather than "GMT" plus an offset.

Codepages 897, 1277 and 5297 are no longer supported No default execution group (you have the option to specify the default

execution group name) while creating the broker Start / stop execution group behavior is changed SOAPInput / SOAPRequest / SOAPAsyncRequest nodes’ Failure action

property is now not configurable. Settings of this property are ignored

Post Migration

IBM Software Group


Post Migration Tasks – Things need to consider HTTPNodes configured to use HTTPS but SSL configuration is not set

results in an error message ‘BIP3135S: An exception occurred while starting the servlet engine connector. Exception text is HTTP Listener LifecycleException…’

ESQL Field references validation with an index of zero is corrected. • Eg: SET OutputRoot.XMLNSC.Row.Column[0].Text = 42; // Incorrect BIP3226E.

SET OutputRoot.XMLNSC.Row.Column[1].Text = 42; // Correct syntax Registry Lookup Node – Default Depth Policy property has been changed Toolkit

• Problems View Configure Filter option is replaced by the down arrow • Broker Development View shows pattern instance projects in a separate pane• Broker Administration Perspective is removed. This functionality is availabe in

Broker Application Development perspective

Post Migration

IBM Software Group


Post Migration Tasks – Things need to consider Deploy EventLog viewer is replaced with Deployment Log View in Broker

Application Development Perspective Command Assistants are replaced by Brokers View Xpath Data Types Viewer shows only Data Types (not Data Types &

Variables)

Post Migration

IBM Software Group


Oh No!!! Now What?

To restore components to a previously migrated version from a v8.0 command environment issue mqsimigratecomponents command with –s (source version) and –t (target version) options

eg: mqsimigratecomponents <BrokerName> -t 7.0.0.3 To restore components on z/OS

Stop the v8.0 broker Submit the BIPMGCMP job to call the mqsimigratecomponents command,

specifying the -s and -t parameters. Restore your Version 7.0 ENVFILE from the backup that you have made, or by

resubmitting the Version 7.0 BIPGEN job. Replace the started task JCL file in USER.PROCLIB with the Version 7.0 copy that

you backed up.
