I have Oracle11 with RAC installed on RedHat 5. I have two servers with two instances one on each one. In each server I succeed connect to appropriate instance of database but not to instance of ASM.

I connect with user oracle11 and type: export ORACLE_SID=+ASM1 sqlplus "/ as sysdba" It connects but write: Connected to an idle instance and when I try to access to parameters or views I have errors.

For know that +ASM1 is the SID I type: ps aux | grep pmon and get: asm_pmon_+ASM1

I tried also with +ASM but it was also unsuccessfully.

What is wrong here?
