I installed Oracle 10gR2 software and created the database manually. i don't remember creating spfile from pfile. But now when i issue the below mentioned query, i can see that there is an SPFILE in the db. How can i check that the DB is using SPFILE rather than init.ora file in $ORACLE_HOME/dbs
SQL> show parameter spfile
NAME TYPE VALUE
------------------------------------ -------------------------------- ------------------------------
spfile string /u01/app/oracle/product/10.2.0
/db_1/dbs/spfileoratest75.ora
