Recently i came across a problem while creating spfile from pfile in RAC. Due to a wrongly added parameter in spfile db was unable to start. I created PFILE from SPFILE on local drive of one node.
SQL> create pfile=’d:\temp\initRACTEST.ora’ from pfile=’+DATA/RACTEST/spfileRACTEST.ora’
I changed the wrongly configured parameter sga_target to appropriate value and then created SPFILE from PFILE.
SQL > create spfile=’+DATA’ from pfile=’d:\temp\initRACTEST.ora’;
Now i checked directory from asmcmd
C:\Users\farhat>asmcmd -p
ASMCMD [+DATA] > ls
DB_UNKNOWN/
TESTRAC/
ASMCMD [+DATA] > cd db_unknown
ASMCMD [+DATA/db_unknown] > ls
PARAMETERFILE/
ASMCMD [+DATA/db_unknown] > cd parameterfile
ASMCMD [+DATA/db_unknown/parameterfile] > ls
SPFILE.259.858334053
OOPS….Something went wrong. Directory should be +DATA/RACTEST/PARAMETERFILE but here a new direcotry created with name DB_UNKNOWN
Lets delete it.
ASMCMD [+DATA/db_unknown/parameterfile] > rm *.*
You may delete multiple files and/or directories.
Are you sure? (y/n) y
ASMCMD [+DATA/db_unknown/parameterfile] > cd +data
ASMCMD [+data] > ls
TESTRAC/
after Google for a while i found that as instance was not started that’s why DB_UNKNOW direcotry is created and file is placed under this directory.
Lets start instance with pfile in nomount state
C:\Users\farhat>set oracle_home=D:\app\Oracle\product\11.2.0.4.0\dbhome_1
C:\Users\farhat>set oracle_sid=TESTRAC1
