Agent up but last instance startup time not being reported correctly
Dana NJan 27 2011 — edited Feb 1 2011My agent, OMS and instance versions are all at 10.2.0.4.0.
In grid control for the instance, I'm getting up to date performance info, alert log data and so on. But the "Up Since" date/time is incorrect. It does not reflect the last time the instance was started.
Why might this be occurring and how can I fix it? I thought about bouncing the agent to see if it would refresh the Up Since date/time, but that might cover up the root cause.
The last instance startup date is being reported in grid control as:
Up Since Jan 7, 2011 8:48:37 AM EST
... but the last time we bounced the instance was:
select startup_time from v$instance;
STARTUP_T
---------
25-JAN-11
Why the discrepancy for that particular item?
Here is the output when I do a status on the agent:

If I can't trust something like a simple "Up Since" from grid control, I worry about putting trust in everything else it's reporting. Is instance startup an item that is on a different refresh cycle than others? I'm new to grid control and trying to get a handle on it.
