The following query, when run on the ASM instance, reflects that it is an ASM instance: ASM_SQL> SELECT INSTANCE_NAME FROM V$INSTANCE; INSTANCE_NAME ---------------+ASM The ASM instance is generally named +ASM, and in RAC configurations, the ASM system identifier (SID) is named the +ASMx instance, where x represents the instance number. The ORACLE_SID environment variable can be set as follows: export ORACLE_SID=+ASM1 When the INSTANCE_TYPE=ASM parameter is set, it signals the Oracle initialization routine to start an ASM instance and not an RDBMS instance.
In this case, the database foreground communicates directly with the ASM instance to coordinate the operation (this is covered in Chapter 2).
