STARTUP RULE OF PRECEDENCE
At instance startup, the rule of precedence is the following:
- spfile<SID>.ora
- spfile.ora if the spfile<SID>.ora does not exist
- init<SID>.ora if the spfile.ora does not exist.
To use an init<SID>.ora when an spfile exists, use the pfile clause with the startup command. For example:
startup pfile=/u01/oracle/dbs/init<SID>.ora
This option is not available for an spfile. Oracle will display the following error message if attempted:
startup spfile=/u01/oracle/dbs/spfile<SID>.ora
SP2-0714:
invalid combination of STARTUP options
DEFAULT LOCATION
If the pfile clause is not used for instance startup, the init<SID>.ora is searched for in the following default locations:
- On Unix
- $ORACLE_HOME/dbs
- On Windows
- %ORACLE_HOME%\database
