Spfile locatin under ASM after recreation

Question

hello,
i run 10g RAC on to SUN nodes with asm. after installation the location of the spfile was correct (+data/pkrac/spfile_pkrac.ora -> linking to +data/pkrac/parameterfile/spfilexxxx) i had to change an parameter, so i created an pfile, changed it and recreated the spfile.
after that the alias is on the same place (+data/pkrac/spfile_pkrac.ora) but the dir <parameterfile> and the link are gone. i find them under +data/dbunknown/parameterfile/spfilexxxxx, which will not be watched by the system.
even when i recreate the spfile by naming the parameterfile dir, then only the alias is under +data/pkrac/parameterfile/spfile_pkrac.ora but the spfile himself again is under the unknown db-dir.
so, how get i my recreated spfile to the right place under +data/pkrac?
thanks, michael

Answer 1

i had to change
an parameter, so i created an pfile, changed it and
recreated the spfile. Did you really need to recreate the spfile because of the parameter change?
You can use Alter Statement to change it rather than recreate it
Example 1
SQL> alter system set PROCESSES=300 SCOPE=SPFILE;
This will automatically update your spfile only
Example 2
SQL> alter system set PROCESSES=300 SCOPE=BOTH;
This will automatically update Memory and spfile.
Note that imediate changes will take effect for only Dynamic Parameters
