Remote Diagnostic Agent (RDA) is a data collection framework, driven from the command line, which can be used to gather diagnostic information related to Oracle products and their environments to assist in problem diagnosis. Full information on RDA is available in Remote Diagnostic Agent (RDA) – Getting Started (DocID 314422.1).
RDA 8.16 improves the collection for Reports 12c, as well as for Business Intelligence (BI) 12c. In addition, further improvements have been made to the Coherence collection and support has been added for Multitenancy functionality in WebLogic Server 12.2.1. Complete details for this release are available in RDA Release Notes (Doc ID 414970.1).
RDA 8.16 is bundled with the 2.11.31 release of Diagnostic Assistant (DA). The DA tool is a command line interface framework designed to simplify and standardize the end user’s experience with various diagnostic tools, providing a common lightweight extensible interface to multiple collection tools (ADR, RDA, OCM, Explorer, etc.). DA packages can also work with Oracle applications (JDE EnterpriseOne, Siebel, PeopleSoft) as verifiers, providing a basic Java interface to facilitate the user’s data collection.
