EM can not start

Hi,

I have installed Oracle10g on HP-UX 11.i.
First few days I was able to administrate my DB through web based EM.

But now I dont know what has happend,Enterprise manager can not connect to the DB instance.

1) My DB instance is started
2) DBCONSOLE is also started.

I am not able to find out the solution.

Regards,

Darshan

Re: EM can not start

Darshan,
after going to http://>machine>:5500/em
do you get a Login to Database:
page? Or do you not get that far?

Re: EM can not start

Hi,

I dont get Login Page, as I was getting previously. It directly redirects me to control page, where DB instance Arrow(Red) is down.But Listener and Agent Arrow(Green) are UP.

Re: EM can not start

Darshan,
so the cookies still have your login details.
To get the login screen back, you can clear your cookies.
However, if you get the control page, what happens if you ask for the DB to be started?
What error message do you see?

Re: EM can not start

Hi Yogiraj,

Normally I restart EM service with

Re: EM can not start

hi Darshan,

Oracle "DBconsole": "emctl start dbconsole" (This will start the dbconsole and agent)

Oracle EM Grid Control "OMS": "emctl start oms"

Oracle EM Grid Control "Agent": "emctl start agent"

Oracle AS "ASControl": "emctl start iasconsole"


hope this helps!

kind regards
