so do you have a file named '/u01/app/oracle/product/10.2.0/db_1/dbs/initdevdb.ora'?
Is there a reason you're not using an spfile?
how to open with spfile can you give me the command
So does '/u01/app/oracle/product/10.2.0/db_1/dbs/initdevdb.ora' exist?
If so post the contents of it.
Create spfile as follows, then try starting the database.
sql> create spfile from pfile='/u01/app/oracle/product/10.2.0/db_1/dbs/initdevdb.ora';
post results from OS command below
ls -ltr /u01/app/oracle/product/10.2.0/db_1/dbs/
why are you using obsoleted & unsupported Oracle version.
How do I ask a question on the forums?
