You Asked

Dear Sir,

Please help me to know below points.

1)difference between DBRM and IORM?
2)difference between ACFS,ADVM and DBFS?


and we said...

DMRM is the database resource manager, which is available on any hardware that Oracle *database* is running. You can control resource utilization by database sessions on the *database* server, eg CPU, undo, lock duration, etc.

IORM is an Exadata only facility. On an Exadata architecture, you have database servers and also storage servers (ie, machines with CPUs that provide storage access to the database). You can control the allocation of resources on the *storage* servers with IORM.

Did you try and google it or maybe read the resulting Oracle Docs?

ACFS -> ASM Cluster File System
ADVM -> ASM Dynamic Volume Manager

DBFS -> Database File System
