enterprise manager: uptime, instance, version unavailable
Hello,
after changing the hostname and upgrading from Oracle 10.2.0.1 to 10.2.0.5 the enterprise manager is not completely working anymore.
I did a drop of the repository with
$ emca -deconfig dbcontrol db -repos drop
and created a new one with
$ emca -config dbcontrol db -repos create
Now the enterprise manager is starting but there seems to be a problem with the connection. I'm logging in with sys as sysdba on the enterprise manager and I see
Status Up
Up Since Unavailable
Instance Name Unavailable
Version Unavailable
Host my-server
Listener LISTENER_my-server
There is an error shown on the top of the page: "Error, java.lang.Exception: No such metric"
The diagrams "Host CPU" and "Active Sessions" are empty and showing "No data is currently available". "Load" and "Paging" is Unavailable too.
What can be the problem? I've recreated the enterprise manager repository several times but it's still the same and so it cannot be a problem with its configuration.
Any hints are appreciated.
