Oracle has replaced the init.ora file because you can now change all parameters dynamically with the ALTER SYSTEM commands. With Oracle9 i, you can manage initialization parameters using a binary server parameter file (SPFILE). By default, a new Oracle9i database will be working on a PFILE, so you must create the SPFILE from the PFILE at the SQL prompt. You can create the SPFILE using the CREATE SPFILE statement, which requires connecting as SYSDBA. Connect system/manager as sysdba; CREATE SPFILE FROM PFILE; This command creates an SPFILE in a nondefault location ($ORACLE_HOME/database). However, you can fully qualify the path name in the CREATE SPFILE statement. CREATE SPFILE='/u01/admin/prod/pfile/file_mydb.ora' FROM PFILE=/u01/admin/prod/pfile/initprod.ora'; After creating an SPFILE, you may encounter an error when you bounce the database. To work around this, you have to reconnect as SYSDBA and use the STARTUP command. The addition of the SPFILE has changed the search path for the Oracle startup deck. In Oracle9i, follow these steps to search for the SPFILE: 1. Search for the spfile$ORACLE_SID.ora file in the default location. 2. Look for the spfile.ora. 3. Search for the PFILE by name: init$ORACLE_SID.ora. SPECIFYING SCOPE Once you have an SPFILE, you can change any initialization parameter with the ALTER SYSTEM command. However, there's an important SCOPE parameter that you need to understand. The SCOPE parameter has three values: SPFILE, MEMORY, and BOTH. Let's look at an example of each. Alter system set db_2k_cache_size=100m SCOPE=SPFILE; If you want to make a change to a parameter in the SPFILE without affecting the current instance, you can do so using the SCOPE=SPFILE option of the ALTER SYSTEM statement. This is useful when you want to make a change starting from the next startup and not for the current instance. Alter system set db_2k_cache_size=100m SCOPE=MEMORY; In the example above, the SCOPE=MEMORY option tells Oracle9i to make the change for the life of the instance and to change it back to the default value the next time the database is bounced. Alter system set db_2k_cache_size=100m SCOPE=BOTH; When you specify SCOPE=BOTH, Oracle makes the change immediately, and Oracle will also make the change permanent, even after the database is bounced.
