CREATE PFILE

Purpose

Use the CREATE PFILE statement to export either a binary server parameter file or the current in-memory parameter settings into a text initialization parameter file. Creating a text parameter file is a convenient way to get a listing of the current parameter settings being used by the database, and it lets you edit the file easily in a text editor and then convert it back into a server parameter file using the CREATE SPFILE statement.

Upon successful execution of this statement, Oracle Database creates a text parameter file on the server. In an Oracle Real Application Clusters environment, it will contain all parameter settings of all instances. It will also contain any comments that appeared on the same line with a parameter setting in the server parameter file.

Prerequisites

You must have the SYSDBA or the SYSOPER role to execute this statement. You can execute this statement either before or after instance startup.

Syntax

create_pfile::=

Description of create_pfile.gif follows
Description of the illustration create_pfile.gif

Semantics

pfile_name

Specify the name of the text parameter file you want to create. If you do not specify pfile_name, then Oracle Database uses the platform-specific default initialization parameter file name. pfile_name can include a path prefix. If you do not specify such a path prefix, then the database adds the path prefix for the default storage location, which is platform dependent.

spfile_name

Specify the name of the binary server parameter from which you want to create a text file.

See Also:

the appropriate operating-system-specific documentation for default parameter file names

MEMORY

Specify MEMORY to create a pfile using the current system-wide parameter settings. In an Oracle RAC environment, the created file will contain the parameter settings from each instance.

Examples

Creating a Parameter File: Example The following example creates a text parameter file my_init.ora from a binary server parameter file s_params.ora:

CREATE PFILE = 'my_init.ora' FROM SPFILE = 's_params.ora';

Note:

Typically you will need to specify the full path and filename for parameter files on your operating system. Refer to your Oracle operating system documentation for path information.
