show parameter spfile
The SHOW PARAMETER SPFILE command is used to display the current value of a parameter in the server parameter file (SPFILE) in Oracle. The SPFILE is a binary file that contains initialization parameters for an Oracle database.
To use the SHOW PARAMETER SPFILE command, you need to connect to the Oracle database using a SQL*Plus session or a similar tool. Once connected, you can execute the following command:
SHOW PARAMETER SPFILE;
This command will display the current value of the SPFILE parameter, which specifies the location of the server parameter file. The output will typically include the parameter name, the current value, and the type of the parameter.
For example, the output may look like this:
NAME TYPE VALUE
spfile string /u01/app/oracle/product/12.2.0/db_1/dbs/spfileorcl.ora
In this example, the SPFILE parameter is set to /u01/app/oracle/product/12.2.0/db_1/dbs/spfileorcl.ora, indicating that the server parameter file is located at that path.
Note that if the parameter is not explicitly set in the SPFILE, the output will show "DEFAULT" as the value.
