Security credentials for BDD targets

The plug-in is configured in a way that lets it discover and work with targets that are deployed in either secure mode (SSL), or non-secure mode. The plug-in also relies on preferred credentials for two of the Big Data Discovery targets — Dgraph and Studio, and sets them automatically at discovery time to the host credential. Many features of the plug-in depend on these credentials being set.

About security credentials in the plug-in

By default, the preferred credentials in the plug-in are set for two targets — Dgraph and Studio, and they are set with a host credential. It is important to have these credentials set so that the plug-in behaves correctly.

You can always set your own credentials. To do so, go to Setup > Security > Preferred Credentials, and on the Security page, select the target, and click Manage Preferred Credentials. For complete details about providing preferred credentials during the target discovery process, see the topic "Setting preferred credentials for a target", http://docs.oracle.com/cd/E24628_01/timesten.121/e28645/install.htm#TTEMP604, in the Enterprise Manager System Monitoring Plug-in for Oracle TimesTen In-Memory Database User's Guide.

If the preferred credentials are not set

The following table list instances where the plug-in does not behave as expected, if the default credentials are not used or if you have not set your own credentials:

Target Feature Behavior if credential is not set
Dgraph On the Cluster target home page, indicate which Dgraph node is the leader node. The leader node is not identified.
Dgraph On the Dgraph target home page, indicate the leader node and the status of the HDFS Agent. The leader node is not identified, and the status of HDFS Agent is not listed (empty).
Dgraph Dgraph request search. An error is issued for the Dgraph target: Default preferred credentials are not set.
Dgraph Dgraph administration operation For each operation, an error is issued for the Dgraph target: Default preferred credentials are not set.
Dgraph Start up and shut down the Dgraph An error is issued for the Dgraph target: Default preferred credentials are not set.
Dgraph View log messages for the Dgraph target. The function is disabled without any warning.
Studio On the Studio target home page, monitor the Dgraph Gateway status The status of the Dgraph Gateway is empty.
Dgraph, Studio View log messages for Cluster target. The function is disabled without any warning.
Studio View log messages for Studio target. The function is disabled without any warning.
