I tried to startup my test instance and i got an error:
SQLDBA> startup pfile=$ORACLE_HOME/dbs/inittest.ora
ORACLE instance started.
ORA-00205: error in identifying control file '$ORACLE_HOME/dbs/c1test.ctl'
ORA-09782: sfifi: another instance has the same database mounted.
Attempting to shutdown instance........ORACLE instance shut down.
I get my test control files are corrupted. Is it right? Please tell me what this error: ORA-09782: sfifi: another instance has the same database mounted means? How i fix it?
