Hi I have modified some SGA related parameters in a RAC installation, two nodes and modified in both through spfile located in a raw device (ASM). The problem is after restarting the database both instance failed to start because it caused ORA-04030. I have tried to create pfile using pfile by performing following procedure: connect / as sysdba connected to an idle instance create pfile from spfile; Error: Not logon This same operation works in single instance database so I guess this is expected behaviour in RAC? TIA
