Oracle ships a driver called oracleasm that is essentially a very low overhead asynchronous direct I/O interface. oracleasm is the preferred I/O submission interface for the Oracle Database running on the Linux platform. And this interface already supports data integrity passthrough. So if you run the Oracle Database with ASM on DIX/DIF-capable hardware we fully support end-to-end data integrity protection today. I.e. checksums are generated/verified in userland by the RDBMS.<br> <p> sys_dio was drafted based on the experiences Joel and I gathered developing oracleasm. sys_dio is an attempt to make the interface generic and not tied to the Database or ASM.<br> <p> </div> Thu, 25 Apr 2013 20:45:54 +0000
