Result! I have finally been able to gather a complete RDA (Oracle Remote Diagnostic Agent) output on my 2 node RAC system. After consulting the relevant documentation on MOS-which is spread over at least 42 Doc IDs-I found them not to be very helpful to the degree that some of what I read is actually wrong or contradicting. I put together a short note, primarily to myself, to remind me of the process. I hope you find it useful, too.
The RDA version I used for this post is 8.14.x from MOS March 4th 2017. My RAC nodes are based on Oracle Linux 7.3/UEK 4.
Starting the data collection
RDA, or the Remote Diagnostics Agent, has been around for a little while. Over the time, and with the growing number of Oracle’s acquisitions it has become, shall we say, a little more difficult to handle. It appears to me as if every one of them will have its diagnostics handled by RDA making it hard to focus on something specific, like for example the database.
I won’t go into very detail of the Remote Diagnostic Agent in this post; please make sure you read and understand the documentation on MOS and the README* files that come with it before using it.
I based this blog post on Oracle Linux 7.2 and RDA 220.127.116.11.14 in case you find this via a search engine.
