I hope this is the correct forum for this stuff... I learned that there is a DBA panel in SQL Developer - which is a great idea. But then, trying it on a RAC database, the output is quite confusing. For example, the init parameters are desplayed twice, or better: once for every instance. But a display column to identify the instance is missing. I assume that the query goes to gv$parameter but doesn't make use of the INST_ID column. Or am I lacking some configuration trick...?
