I present a problem when entering the databases that we want to monitor, apparently there is a blockage. I tell you that de-register the databases of the trial version of the DPA who were on a server and repository QA, now while trying to register the bases in the licensed on the server and productive repository version throws me the following error, it is with all bases that tests were done and add one that was not on the evaluation and monitoring step without problems.
This looks like we are having some error with the UTL_CON package that is run on the registration of DPA for Oracle. If you click back from that screen and hit back to screen 3 there is a option to manually run the package from a link see if you can click that and follow the instructions and then if needed please open a support case.
here is a link explaining the package some.
