Edit spfile manually

CREATE SPFILE. Purpose. Use the CREATE SPFILE statement to create a server parameter file from a client-side initialization parameter file. Server parameter files are binary files that exist only on the server and are called from client locations to start up the database.  · Usually there is no need to edit the spfile manually. I didnot say i have to edit the spfile manually i said if you dont want to use alter system you can edit the pfile and convert it to spfile There is also no need to rename the spfile to make sure Oracle can't find it. If you rename the spfile and the pfile exists then the system will use the pfile instead of the spfile.  · On a UNIX (-like) system, you can create a perfectly valid PFILE from any SPFILE with the command: $ strings www.doorway.ru www.doorway.ru You *can* also edit it directly, providing you have a binary-capable editor (e.g., “emacs”).Estimated Reading Time: 2 mins.

On a UNIX (-like) system, you can create a perfectly valid PFILE from any SPFILE with the command: $ strings www.doorway.ru www.doorway.ru You *can* also edit it directly, providing you have a binary-capable editor (e.g., "emacs"). Forget editors like 'vi' -- the standard 'vi' editor does bad things to binary files, like replacing ASCII NULs with spaces. Because the SPFILE is a binary file, do not directly edit the SPFILE with an editor. Instead, change SPFILE parameter settings using Oracle Enterprise Manager or ALTER SYSTEM SQL statements. When creating an SPFILE, if you include the FROM MEMORY clause (for example, CREATE PFILE FROM MEMORY or CREATE SPFILE FROM MEMORY), then the CREATE statement creates a PFILE or SPFILE using the current system-wide parameter settings. Above statement failed because “processes” is Static parameter and can be used with SCOPE=SPFILE only. SQL alter system set processes= scope=spfile; System altered. You can view the new value in V$SPPARAMETER view as the SPFILE is updated. SQL select name, value, isspecified from v$spparameter where name ='processes';.

The spfile is a server-side initialization parameter file; get stored in the spfile unlike the pfile, which has to be manually edited. Although you can open the binary server parameter file with a text editor and view its text, do not manually edit it. Doing so will corrupt the file. Then you have to edit the pfile/spfile for the new location of the control files. In my backup concept, I do a manual backup of the spfile and the.
