We have MVs that get refreshed nightly from Oracle On Demand data. Within the last week the refreshes have gone from 3 hours to 20 hours. We don't see a massive increase in data, there are no errors in the logs and pings are returning in a reasonable amount of time <200ms. The only thing we see is the following message in Enterprise Manager:
Metrics "Database Time Spent Waiting (%)" is at 47.91113 for event class "Network"
As the pings look to return fast enough, I'm not sure where to go with this message.
Any suggestions would be appreciated.
