Hello
SQL> startup
ORA-27102: out of memory
HPUX-ia64 Error: 12: Not enough space
SQL> exiterror is not related to space on your mount point. it is related to memory.
if you are getting this error means chekc at the OS level whether something is consuming more memory due to which it is not allowing oracle to allocate sga.
Check top/sar/glance to see who is consuming more memory

ORA-19808: recovery destination parameter mismatchit is not the best practice to maintain differnet parameters for each instance in RAC env. also check db_recovery_file_dest and db_recovery_file_dest_size is same on all node. it should be same i.e it should be a shared location.
