oracle Idle instance


I installed oracle express edition. But when I connect as

sqlplus / as sysdba
its showing as connected to "Idle instance."

When I type startup its showing below error

SQL> startup
ORA-01078: failure in processing system parameters
ORA-01565: error in identifying file 'C:\oraclexe\app\oracle\product\11.2.0\serv
ORA-27041: unable to open file
OSD-04002: unable to open file
O/S-Error: (OS 2) The system cannot find the file specified.

Can you please help how can I resolve this issue.

Check if under path "..../oracle/product/10.2.0/db_1/dbs/

Go to "C:\oraclexe\app\oracle\product\11.2.0/<<db home>>/dbs" path , check if  inittest.ora file is present or not.
If not then create the pfile from spfile and startup the database .

Sample to create the pfile:
SQL>  create pfile from spfile='C:\oraclexe\app\oracle\product\11.2.0/<<db home>>/dbs/<<spfile>>.ora';

I wouldn't create a pfile just yet and if Oracle cannot find the spfile, then that command won't work.

Verify if the spfile exists.
If not, what happened?  They just don't delete themselves.

We could probably walk you though this and get it back up and running but it will likely take time.

Unless you have a lot of data in the database that you don't want to lose:  Since this is XE, you might be better off dropping and recreating the database.
