    doubt about parameter files?

    hi,i created database by using dbca tool,ofter that i created p-file from init.ora file.now my system having both p-file and sp-file,but when i startup the database system is starting with p-file.why its happening like this? if the sp-file available oracle should startup the database with sp-file ..but in this why happening like this? and ofter that i deleted p-file and try to startup the database with sp-file,but oracle is showing errors, even sp-file is available.
    like ORA-017108-failure in processing system parameters
    and LRM-00109-could not open parameter file.
    why happening like this ..sp-file is enough to start the datbase?
    please send me the answers..iam learning dba ..
    thanks.

    I believe it's a typo. isn't it?

    three possible reasons ... 1. you might have deleted the spfile also 2. spfile may not be in the correct location where it is suppose to be 3. you might have rename the spfile

    what is the OS?

    SQL> create pfile='/mnt/oracle/initARM.ora' from spfile;

    I get the following error..

    ORA-07391: fopen error, unable to open text file.

    Kindly let me know is the syntax correct and what has to be dont orectify the error?

    OR

    SQL> create pfile='C:\oracle\product\10.2.0\db_1\admin\sos\pfile\initsos.ora'
    2 from
    3 spfile='C:\oracle\product\10.2.0\db_1\database\spfilesos.ora';

    File created.

    i hope this will work.

    make sure /mnt/oracle exists.

    if /mnt/oracle exists then check if oracle account has privileges to write on it.
