Hi,
I have an Oracle 11gR2 database running on Exadata.
For a long running batch/job, one of the Top wait event that i have is "enq:HV - contention".
I have found that adding the hint HWM_BROKERED in the relatded SQL-statement (this is an insert), can be a possible solution.
See Metalink Note: 452719.1
Does someone has experience with this hint? It disables some _* parameters. Why can this be a work-around?
Doing so, will not ensure that the HWM is protected.
Thanks and Regards
