7.5 HA 5.5.3, 7.4 HA 4.11.3 PTFs

PowerHA SystemMirror for i 7.5 with HA 5.5.3 and 7.4 with HA 4.11.3 continues to evolve, bringing several significant enhancements to the web interface, administrative domain, and two additional SQL services.

PowerHA Modern Web Interface 7.5 HA 5.5.3 7.4 HA 4.11.3

The PowerHA modern web interface now provides the ability to perform several management operations, including the ability to perform the following types of operations:

• Start and end cluster nodes

• Administrative domain management, including:

  • Start and end administrative domains

  • Add and remove monitored resources

• The ability to manage switchable environments, including the ability to:

  • Start and end cluster resource groups

  • Perform administrative switchovers and failover

  • Manage replication sessions with the ability to suspend, resume, detach, and reattach replication.

In addition, the web interface has improved customization that enables searching, sorting, filtering, and selecting columns for tables within the interface with the ability to see dynamic SQL code that will generate a similar view.

For additional information on the PowerHA Web Interface, see Configuring the PowerHA Web Interface.

Enhanced Administrative Domain Integration 7.5 HA 5.5.3 7.4 HA 4.11.3

The administrative domain in PowerHA synchronizes security and configuration-related objects across a PowerHA environment, including user profiles, so that changes to resources monitored by the administrative domain are automatically synchronized with the other nodes.

The administrative domain now has the following enhancements:

• Improved synchronization of resources when changes occur with adopted authority, reducing the need for manual intervention.

• The administrative domain makes it easy to add multiple user profiles based on selection criteria. This update simplifies the ability to omit IBM profiles when adding user profiles to the administrative domain by specifying OMIT((*IBM)) on the ADDCADMRE command or by using the option on the web interface to omit IBM-supplied profiles.

• It is now also possible to add multiple user profiles in batch jobs with a new confirm parameter on the ADDCADMRE command to bypass the confirmation screens.

Administrative Domain Example 1 - adding all but IBM-supplied profiles to the administrative domain:

ADDCADMRE RESOURCE(*ALL) RSCTYPE(*USRPRF) OMIT((*IBM))

Administrative Domain Example 2 - adding all but IBM-supplied profiles to the administrative domain while bypassing the confirmation screen (batch-mode compatible):

ADDCADMRE RESOURCE(*ALL) RSCTYPE(*USRPRF) OMIT((*IBM)) CONFIRM(*NO)

PowerHA SQL Services 7.5 HA 5.5.3 7.4 HA 4.11.3

PowerHA continues to provide additional SQL services as the strategic method of retrieving PowerHA information programmatically. In addition to providing the ability to see equivalent SQL queries for information presented via the web interface, PowerHA now has the ability to retrieve HyperSwap status information via SQL with two new SQL services:

• QHASM.HYPERSWAP_STATUS_LIST view

• QHASM.HYPERSWAP_STATUS_INFO Table Function
