Hi,
I wasn't able to convince the DBAs. They make sense telling me that if I get the exact same error in an "non production" enviroment with an embedded SQL Express, I shouldn't be touching the production Oracle database while the only thing the two enviroments have in common is OS and vCenter versions. The rest of things are different.
I'm starting to get so frustrated with this...the charts finally show but they take forever to do it. So beside the confusing errors in the logs, the charts in the "Performance/Overview" tab DO SHOW UP but after a really long time. Again, this happens with an external Oracle 11g database and with a pre-production enviroment (nested in my laptop) with an SQL 2008R2 embeded database.
Response times are "inmediate" with a VCSA and the embeded vPostgres...sadly for me, I need to fix this for the vCenter server enviroments.
