UPDATE HISTORY
1st August 2013 - Updates for WebSphere MQ version 7.1.0.3
15 August 2012 - Updates for WebSphere MQ version 7.1.0.2
31 May 2012 - Updates for WebSphere MQ version 7.1.0.1
11 November 2011 - Updates for WebSphere MQ version 7.1.0.0


++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Section 1 : Release notes - What's new in this release
++++++++++++++++++++++++++++++++++++++++++++++++++++++++

v7.1.0.3
---------
From fix pack 7.1.0.3, Windows 2012 is now supported, although the installation image needs to be the one updated to the 7.1.0.3 level in order to take advantage of this new support.

v7.1.0.2
---------
From fix pack 7.1.0.2 onwards, WebSphere MQ queue managers and MQI clients enforce the Triple DES (3DES) recommendations from FIPS SP800-67 when configured in FIPS mode. This means that the FIPS 140-2 compliant 3DES CipherSpecs may only transfer a maximum of 32Gb data using a single session key. This limit does not apply if WebSphere MQ is not operating in FIPS mode. By default, FIPS mode is disabled.

If a channel transfers more than 32Gb data in FIPS mode, it terminates with error AMQ9288. This restriction applies to all channel types. When client connection conversation sharing is enabled, the 32Gb limit applies to the total amount of data sent by all connections which are sharing the same secure socket.

The affected 3DES CipherSpecs are:

ECDHE_ECDSA_3DES_EDE_CBC_SHA256
ECDHE_RSA_3DES_EDE_CBC_SHA256
TLS_RSA_WITH_3DES_EDE_CBC_SHA

To avoid the AMQ9288 error when using FIPS mode, take one of the following actions:

1) Alter your channels to use a different CipherSpec which does not use 3DES.
2) Enable secret key reset to ensure that session keys are reset before 32Gb data is transferred.
3) As a last resort, you can disable FIPS mode (although this is not recommended).


+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Section 2 : Limitations, known problems and other changes
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

APAR IV31952
--------------------------------
The fix for APAR IV31952 changed the authority checks that WebSphere MQ makes on channel objects when you run the RESET CHANNEL command. Applying this fix can give changed behavior and you might need to alter some authorities.

Your systems are affected only if your channels run with an MCAUSER userID resolving to a non-mqm user.  The Reset Channel command can run internally within WebSphere MQ code, so, even though you have not run the Reset Channel command manually, your system might still be affected.

Ensure that, at a minimum, your channel's MCAUSER userID has both +DSP and +CTRLX authority on the channel object, so that the userID can run Reset Channel commands.  Before the fix for IV31952, WebSphere MQ checked that the userID had +ALTUSR authority which you might previously have granted to make your channel work.

After applying fix pack WebSphere MQ fix pack 7.1.0.3 or later, you can remove your MCAUSER's +ALTUSR authority on the channel object because it is not required for the Reset Channel command.  You should also check that your MCAUSER userID has +DSP and +CTRLX authority on the channel object.

Uninstallation on AIX and HP-UX
--------------------------------
There is logic in the uninstallation process to prevent inadvertent removal of the WebSphere MQ installation in use for running queue managers. This logic has been seen to be faulty on AIX and HP-UX, where it is possible to uninstall while queue managers are still running, using that installation.

Please check carefully that all queue managers running on an installation that you intend to uninstall are shut down prior to the uninstallation process. Please also check carefully that you are uninstalling the intended installation, as we are unable on these platforms to prevent you from accidentally uninstalling a
different installation on which you still have running queue managers.

This is a permanent restriction in WebSphere MQ 7.1 and its fix packs.


Windows migration to v7.1
--------------------------
If you migrate from an earlier version of WebSphere MQ to v7.1 on the Windows platform, you may experience one or both of the following issues:

The MQ service and MQ Alert Monitor (task bar icon) may fail to restart following migration, unless they are terminated prior to migration. These will record errors that are visible in the event viewer, with symptoms such as amqxcs2.dll not found, or Application SID does not match the Connection SID. The migration
process will succeed, and these errors can be ignored, but the MQ service and Alert Monitor may need restarting manually following migration.

After migration, the 'Remove Fix pack' icon(s) may not be removed from the Start Menu. These icons can be safely removed manually since they apply to the pre-migration installation at an earlier version.

This is a permanent restriction in WebSphere MQ 7.1 and its fix packs.


HP-UX Non-IBM licence text display
-----------------------------------
When viewing the Non-IBM licence text in text-only mode on HP-UX, no text is visible. There are no Non-IBM licences applicable, but this is not made clear when viewing in this mode.

This is a permanent restriction in WebSphere MQ 7.1 and its fix packs.


WebSphere MQ Telemetry Service log file permissions on UNIX/Linux
------------------------------------------------------------------
The permissions for log files created by the WebSphere MQ Telemetry Service (mqxr.log, mqxr.stdout, mqxr.stderr) are not consistent with other WebSphere MQ log files and may require an authorised user to modify the permissions to enable other users to read their contents, for example when diagnosing
problems.

This is a permanent restriction in WebSphere MQ 7.1 and its fix packs.


MQ Explorer migration
--------------------------------
On a multi version system, if migrating from MQ V7.0.1.6 or higher to MQ V7.1 or higher, any queue managers that are not auto start do not appear as running in MQ Explorer after they have been manually started. To see the queue managers appear as running, restart MQ Explorer.

This is a permanent restriction in WebSphere MQ 7.1 and its fix packs (internal defect 155539).


XMS .NET application hangs when closing a long waiting consumer
----------------------------------------------------------------
For Windows applications using IBM Message Service Client for .NET (also known as XMS .NET), in unmanaged client mode, a hang delaying closure of the application can be observed if consumer.close() is called subsequent to a client reconnection.

Unmanaged client mode is configured by setting the connection factory connection mode property to XMSC.WMQ_CM_CLIENT_UNMANAGED. If this is used in combination with automatic client reconnection, and a reconnection occurs, then calls to consumer.receive() or consumer.receive(wait), where wait is an extended timeout period, will hang during closedown due to a clash with the processing in
consumer.close().

The above problem is being addressed by internal defect 155741.

3.1 Download location
----------------------
Download WebSphere MQ fix pack 7.1.0.3 from the following location:

http://www.ibm.com/support/docview.wss?uid=swg21254675


3.2 Prerequisites and corequisites
-----------------------------------
Before downloading WebSphere MQ V7.1.0.3, perform the following steps:

1. Ensure that your system meets all the system requirements:
http://www.ibm.com/software/integration/wmq/requirements/index.html
This action prevents technical problems that might occur after the installation and configuration of the fix pack.

2. Review the Flashes and Authorized Problem Analysis Reports (APARs) on the WebSphere MQ for
UNIX and Windows product support Web site:
http://www.ibm.com/software/integration/wmq/support/

APARs describe defects that have been addressed in a fix pack, For a list of WebSphere MQ v7.1.0.3. APARs, refer to:
http://www.ibm.com/support/docview.wss?rs=171&uid=swg27024302

3. Ensure that you have sufficient file system free space to download and extract the fix pack. You need to have a file system with one gigabyte of free space to contain the compressed file and the uncompressed installation image.

4. Ensure that you have the free space required to install the fix pack. The free space must be available in the location of the WebSphere MQ installation that you are updating.

To determine the space used by the existing WebSphere MQ products on UNIX platforms, perform the command:

du -k -s MQDIR

where MQDIR represents the location where the WebSphere MQ product is installed.

5. If you already have the WebSphere MQ v7.1 product installed and have obtained special fixes, contact IBM(R) support to determine whether you need an updated version of the fixes before you install WebSphere MQ v7.1.0.3. This helps to ensure that your system is in a consistent state and that no special fixes are lost.
