Database upgrade through DBUA cant detect database

Question

Hi,
I have a HP UNix box . There are 7 instances 2 in 9.2.0.8 and 5 in 10.2.0.1 upgraded earlier than my joining. I want to upgrade one of the 9.2.0.8 databases.
The database to upgarde is up and running and can be connected through listener.
I login as the owner of ora10g and start dbua. It shows me all the 7 databases but when I select the database to upgrade it throws the following info :
The Upgrade Assistant Failed in bringing up the database xxxx. Oracle Home /oracle/9.2.0.8 obtained from /etc/oratab was used to connect to the database. Either the database is not running from Oracle Home /oracle/9.2.0.8 or correct Initialization pfile was not found.
It then asks for pfile. -----------------------------------
The database is up and running.The Oracle home is also correct in Oratab file.
I checked the sqls.log file
It has info like
set heading off
set pagesize 0
set feedback off
set linesize 2048
set sqlprompt 'SQL_ENGINE_END_OF_SQL'
show sqlprompt
set sqlprompt 'SQL>'
set sqlprompt 'SQL>';
set heading off
set pagesize 0
set feedback off
set linesize 2048
set sqlprompt 'SQL_ENGINE_END_OF_SQL'
show sqlprompt
set sqlprompt 'SQL>'
connect /****** as SYSDBA
select count(*) from v$instance;
set heading off
set pagesize 0
set feedback off
set linesize 2048
set sqlprompt 'SQL_ENGINE_END_OF_SQL'
show sqlprompt
set sqlprompt 'SQL>'
Please help on this issue . Y cant the DBUA see that database is up?

Are you able to start/stop instance by using the dbstart/dbshut command? If not, verify your oratab files has accurate information and it has the Y flag to let the admin scripts manage the instance.
