Re: ORA-00205: error in identifying control file,

You should probably start the database nomount then create a new controlfile with the create controlfile command; from your 10.2.0.4 database you can generate a basic script to do this by issuing the following command at the SQL> prompt:
alter database backup controlfile to trace; Edit the resulting script to open the database resetlogs then run it after a startup nomount.

Subject: ORA-00205: error in identifying control file,
I am doing a manual upgrade from 10.2.04 to 11.2.03. I have installed 220.127.116.11.
Copied TNSNAMES and LISTENER.ora,init.ora from 10g home to 11g home respective directories. Commented all dump_dest paramteres in 11g init.ora and added diagnostic_dest parameter
exported all the varaiables as follows.
export TNS_ADMIN=$ORACLE_HOME/network/admin export ORACLE_BASE=/oracle/ora11203/app/ora11203 export LD_LIBRARY_PATH=/oracle/ora11203/lib:/usr/local/lib
Now when i try to start DB from the unix session where all of above variables are set,i am getting following issue.
sqlplus '/as sysdba'

The following entry is present in init.ora.If I keep this entry or comment it out,Iam getting same issue.
control_files = (/oracle/ora11203/dbs/ctrl_1_OMIGTEST.ctl)
Do i copy control file from 10g home and place in in 11g path and mention it in init.ora before upgrade?
Thanks and Regards,
