ASM Instace will provide Database Instance with ASM File Extent Map . ASM File Extent Map will show Database Instance where file's extents . After that Database Instance can perform direct I/O to the Database File. So where is the ASM File Extent Map ?What store ASM File Extent Map ? somebpdy can tell me ???
