Security Software

Hi,

I have OAS10.1.2.0.2 installed on linux box.
everything was working fine until i did the following.
i change the orasso password at 3 locations:
1. EM orasso schema password
2. LOGGED into oidadmin and changed the orasso PASSWORD
3. CHANGED PLSQL database password in the dads.conf for /pls/orasso

but then when i restarted all the components and when i try to login to page as follows,
http://oracledev:7777/pls/orasso/orasso.home

i was getting following error:
Service Temporarily Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
--------------------------------------------------------------------------------

How can i fix this error. Can someone guide me please.

Thanks,
Philip.
