to the OP, no one knows what GBU's do anyway. what does GBU Support actually Support? I have people in Springs and they did not mention anything.
to the person whining about support asking for logs, if you are so smart, why are you opening a support request? figure it out yourself. or maybe you are not including the logs that are actually being requested? do you have any idea how much a support engineer is hounded on a daily basis by multiple managers, directors, senior directors, escalation managers, critical account managers, customer success managers, duty managers, etc etc etc telling them to not ask for logs that have already been requested and to not do this or that and to do this or that instead. dealing with customers who don't have the first clue about how to use the product or are doing something so off the wall with it that no one else has ever attempted what they are doing.
and of course, the products don't work, if I owned a company, I wouldn't let an Oracle sales rep in the door.
