What’s in Command Levels 90x

MQ90x StairsIBM MQ released Long Term Support release V9.0.0 back in June 2016 which had a Command Level of 900. The subsequent Continuous Delivery releases, V9.0.1, V9.0.2, V9.0.3 and V9.0.4 have each introduced their own Command Levels, 901, 902, 903 and 904 respectively.

This post captures the changes that are available in each of those Command Levels.

Release Command Level Features protected by Command Level – details below
V9.0.0.0 900 AMS Protection Policy enhancement – Confidentiality Policy
LDAP Authorization on Windows
V9.0.1 901 No changes protected by Command Level
V9.0.2 902 Log management features
V9.0.3 903 No changes protected by Command Level
V9.0.4 904 z/OS only Advanced Capability attribute on the queue manager object

AMS Protection Policy enhancement – Confidentiality Policy

With the introduction of Confidentiality Policies in Command Level 900, there is a new attribute on the Set Policy command. A confidentiality policy has no signature algorithm, but does have a encryption algorithm. The Key Reuse feature is applicable to this type of policy. Jon Rumsey has a great write-up of this IBM MQ V9 feature on the MQDev blog, MQ V9 Fast encrypted messages with MQ – Introducing AMS Confidentiality Policies.

The fields now available on Windows are the same as those noted in the earlier post for Command Level 801, and are not repeated here.

Log management

With the introduction of Automatic management of linear log extents, and Automatic writing of media images, in Command Level 902, there are new attributes on the queue manager object, queue manager status, and one on queue objects. Mark Whitlock has written about this in an MQDev Blog Post: Logger enhancements for MQ v9.0.2.
