Enhancements:

ABILITY FOR SUPPRESSION FOR NONOCCURRENCE SEASONALITY EVENTS WITH RELATED EVENTS

https://bigblue.aha.io/ideas/ideas/IRISCART-I-713

When nonoccurrence Seasonal Rules are active, and the affected Seasonal Events are associated with many Related Events, it can lead to many nonoccurrence events being created, when nonoccurrence happens. This RFE provides an option to create just one single synthetic event on the nonoccurrence of events related to the seasonal event. Too many events are being created for Seasonality nonoccurrence when SE events have associated Related Events. Need the ability to suppress

For more information about this function, see: line-configuring-suppression-nonoccurrence-seasonality-events-related-events
Add Root Cause Analysis policies to Impact

https://bigblue.aha.io/ideas/ideas/IRISCART-I-925

The probable-cause analysis is performed in "Watson for AIOps Event Manager" automatically for events that have been grouped by a topological association. By default, the Node field of the synthetic parent event created is set to the unique group identifier for the group. Also, by default, CNEA sets the Summary field of the synthetic parent event to include the Summary field of the child event with the highest probable cause score. It might be desirable to also align the Node field of the synthetic parent event to match that of the child event with the highest probable cause score.

Included within Netcool/Impact 7.1.0.27 is a new project, EventManagementAnalytics, which allows you to perform probable-cause analysis for other types of grouped events also. You can also modify the weightings applied for the different criteria, as well as add custom keywords that are important to your organization. The project also has a Policy and Service that causes the Node field of synthetic parent events to track to the Node field of the child event with the highest probable cause score.
Note : for upgraded full cloud NOI systems, a manual step is required to create the EventManagementAnalytics project. See here for details.

Add the ability to create a new OMNIbus Event Reader through command-line interface

https://automation-management.ideas.ibm.com/ideas/IRISCART-I-366
https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=143176

The ability to allow for the creation and modification of Event Readers can be accomplished through the command-line api interface. The Netcool/Impact documentation contains instructions on how to create an OMNIbus Event Reader that uses Impact's REST API.

For more information about this function, see:
https://www.ibm.com/docs/en/tivoli-netcoolimpact/7.1?topic=oers-creating-new-omnibus-event-reader-from-command-line

An extra custom field requested in the Operator view maintenance window

https://automation-management.ideas.ibm.com/ideas/IRISCART-I-370

http://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=147023

A new "Description" field is now available to allow for the insertion of comments and notes within the Maintenance Window

For more information about this function, see: management-about-mwm-maintenance-windows

Refer to: known-issues_for_NOI_full_install_maintenance-window
Consistency between the creation of Synthetic Events (Related Events and Patterns)

For Pattern Synthetic Events: AlertGroup is taken from an Event (whereas for Related Events Synthetic Events - AlertGroup is "Synthetic Event - Parent") Providing the ability to do the same as "Related Events Grouping" and "Patterns Grouping"
Enable SSL Connections with an Oracle DSA.

https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=16342

The ability to connect to an Oracle DSA with SSL enabled, can be accomplished.

For more information about this function, see: versions-enabling-tls-connections-oracle-database
The impact_server_health_check.sh script now automatically scans the "tmp" space and determines whether there is enough space to allow for possible data collection during upgrades. If not enough space is available, the script terminates the scan and provides the option to set an environment variable to point to a location with more available space, for example:

export IBM_JAVA_OPTIONS=-Djava.io.tmpdir=<directory_with_space>

Cannot save OAuth data sources with a blank Client Secret

Symptoms: When attempting to save an OAuth data source, the save fails with a validation error, "Client Secret is a required field." even though the Client Secret should be an optional field.

Resolution: Enter a temporary value into the Client Secret field and save the OAuth data source as normal. And after saving the data source change, perform the following actions:
1. Edit the .ds file found at: <IMPACT_HOME>/etc/<SERVER>_<DATASOURCE>.ds
2. Locate the CLIENTSECRET field and delete the value: <DATASOURCE>.OAUTH.CLIENTSECRET=
