Hello all. This blog discusses the recent release of support for both Teradata TD2 and LDAP authentication mechanisms in Teradata Viewpoint. Support for Teradata TD2 and LDAP authentication mechanisms was made available in the Teradata Viewpoint 13.11.00.04 patch release.
The normal goal is to release new enhancements in actual Viewpoint releases instead of patch levels for various reasons including customer visibility, supportability, etc. However we also need to balance priority of the need with timing of release and consider exceptions where necessary. This is one of those cases. As you probably already know, Teradata Database supports TD2 and LDAP authentication mechanisms where either can be selected as the system default. In the past, Viewpoint was limited to supporting only TD2 which caused some grief and frustration to those who selected LDAP as their Teradata DB system wide default.
One might wonder why this is important considering Teradata Viewpoint has its own user identities and roles that don't directly rely on Teradata Database logins. For the most part that is true, but there are operations and configurations where the Teradata DB authentication becomes relevant. These instances now allow for both methods and support of the default whichever it is set to. So let's take a closer look at this new feature.
The first area that has differences is the Admin -> Teradata Systems -> General interface. The LOGIN section now has an authentication selection for the Viewpoint logins connecting to Teradata. This is followed by a new section that determines what authentication mechanisms will be offered in user interfaces within Viewpoint. These new sections look like this:
Dependent on these settings, the user interfaces for login prompts associated with the various Teradata Database actions change. For instance, aborting or changing workloads for queries in Query Monitor or adding space in Space Usage. Here is a view of how that is going to change based on these settings.
The other place worth mentioning is in the Profile setup as this is a self service aspect of Viewpoint and therefore may be seen but the business users of Teradata Viewpoint. The profile is setup to link your Viewpoint user identity with various Teradata Database credentials. This is then used by the MyQueries portlet in determining the queries that should be displayed in that portlet. This interface will adjust as follows:
While I have your attention, a few other things we snuck into this patch release of additional value for Alerting.
Blocking alerts now include the username and session identifier of the blocker
Session alerts now offer the ability to abort the session and send an email notification
Alert Viewer portlet now provides the alert name with an abort session action
