ASM pfile lost in Oracle RAC 11gr2

Question

Hello Gurus,
I am new to Oracle RAC 11gr2 and facing some issues. our spfile/pfile for asm instance is lost and I am not able to startup the asm instance.
Environment is as below:
RAC 2 nodes
Oracle RAC 11gr2
Enterprise Linux Server release 5.5 (Carthage)
ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/u01/app/oracle/product/11.2.0/db_1/dbs/init+ASM1.ora'
Is there any way to recover the spfile/pfile ?
Also getting following error while try to connect " sqlplus / as sysasm"
$ sqlplus / as sysasm
SQL*Plus: Release 11.2.0.1.0 Production on Sun Mar 27 11:26:02 2011

Hi,
Do we need to Set variable ORACLE_HOME properly (Grid Home) while starting RDBMS instance?
e.g ORACLE_HOME=/u01/app/11.2.0/grid*I recommend you set ORACLE_HOME properly for each Oracle Installation when you use SQLPLUS.
i.e: cat /etc/oratab
orcl:/u01/app/oracle/product/11.2.0/db_1
db10g:/u01/app/oracle/product/10.2.0/db_1
+ASM1:/u01/app/11.2.0/gridAlso you can startup/shutdown our database with SQLPLUS using ORACLE NET*, but it must be configured properly.
My recommendation <s>is always</s> use SRVCTL and CRSCTL to manage to your environment. Track all the process of initialization processes through the logs using ADRCI utility (only 11.1 or later).
When use SRVCTL or CRSCTL to manage I recomend you use (GRID HOME).
SQL> alter database open;
alter database open

ORA-16038: log 3 sequence# 1067 cannot be archived

ORA-00312: online log 3 thread 2: '+FRA/yyy/onlinelog/group_3.259.738489481'
SQL>I give to you three options:
1° - Add more asmdisk on Diskgroup +FRA
2° - Make backup of all archivelog using RMAN and option delete input (i.e backup archivelog delete all input;)
3° - If this database is for TEST ONLY and you not need backup or recovery of then you can delete all archivelog using RMAN (i.e delete archivelog all;)
I recommend you create routine of backups of the database and archivelog to prevent this area becomes exhausted.
If you need the database in archivelog but it is only to test then create routine to delete archivelogs periodically.
If you dont need the database in archivelog, then just disable it.
