Summary: Learn how to generate an SPFILE from a PFILE in Oracle 19c. Understand the step-by-step process and commands required for seamless configuration.
---

In Oracle Database 19c, creating a server parameter file (SPFILE) from a parameter file (PFILE) is a straightforward process. Here's a step-by-step guide to help you achieve this:

Locate the PFILE: First, you need to know the location of your PFILE. Typically, it's named init{SID}.ora and resides in the $ORACLE_HOME/dbs directory.

Connect to SQL*Plus: Open a terminal or command prompt and connect to SQL*Plus using a privileged account, such as SYSDBA or SYSOPER.

Start the Instance in NOMOUNT Mode: Before creating the SPFILE, start the instance in NOMOUNT mode. This step ensures that the database is not mounted or open.

Create the SPFILE: Use the CREATE SPFILE command to generate the SPFILE from the PFILE. Specify the location of the PFILE in the command.

Replace <path_to_pfile> with the full path to your PFILE.

Verify the Creation: After executing the command, Oracle will create the SPFILE from the specified PFILE. You can verify this by querying the V$PARAMETER view to check if the parameters are loaded from the SPFILE.

This query will display all the parameters currently set in the database.

Shut Down and Restart the Database: Once the SPFILE is created and verified, shut down the database and restart it to ensure that the changes take effect.
