Index need to be check when migration the database server

We migrate our Oracle Database one server to another one.
we cross checked the two databases . all were OK.
even if parameters, memory size, objects , network all were ok

but our new database was performing very slow for some application reports,
we can't able to find. whats the cause??

after three days, we find that two big index were not import to new server.
after creating these. we solve our problem.

Network Cable unplug of the server

I want to share A Practical experience of mine.
yesterday, we install (patch of sun solaries spark) OS patch to our production

It takes at least four hours, after this we shutdown our oracle Database server.
at first all were right but after 10 minutes we were not able to connect to server
without console.

We checked all possible option but failed.
suddenly, one of our system admin unpluged the network cable then plug.

after this all were 0k. we don't whats the problem? may be port hang.. or may be something else ....
