How Does Database Connects To Asm Instance?

1.	How Does Database Connects To Asm Instance?
Answer» The database communicates with ASM instance using the ASMB (umblicus process) process. Once the database obtains the necessary EXTENTS from extent MAP, all database IO going forward is processed through by the database processes, bypassing ASM. Thus we SAY ASM is not really in the IO PATH. The database communicates with ASM instance using the ASMB (umblicus process) process.
