Currently, all I have is problem to resolve. We will think about a general model.. For Oracle to support running RAC on a single fabric - assuming the fabric is utilized for both network (inter node cluster com) plus storage I/O - we need to limit /control latencies of cluster network msgs such

Some application level protocols - require higher QoS levels than others - for various communication and I/O operations. For example, cluster inter-node health msgs have fixed latency requirements that if exceeded may result in unexpected node removals from the cluster. Are there any

as a replacement for IT-API / uDAPL / and standard UDP. Again any platform with support for RDS will have a significant performance advantage. We will fall back to running with UDP on HPUX.

We need both - each for different Oracle clients / functionality with respective connection models / modes of operation (stream vs datagram). BTW - Oracle currently uses TCP streams / SDP for Client / middle tier connectivity to the database. We use UDP / RDS within the database for inter

We also use TCP streams for disaster recovery archiving involving very large amounts of data. We would like to move this to SDP via AIO too. On Thu, 2006-01-05 at 20:07 -0500, Richard Frank wrote: We need both - each for different Oracle clients / functionality with respective connection

We do not see any deficiencies - the RDS specification and current implementation so far meet our requirements and is working very well. There is more we will want to do further down the road - such as access the RDS sockets via AIO so we can add zero copy support. On Thu, 2005-12-01 at
