When I try to set up two RDR service on the same disk,
on different partitions, asemgr complains about it.
Is this against the rule?

Yes, that is not supported. If you have two different partitions on the same disk as DRD disks, they must both be in the same service. The reason for this is that ASE can access a specific disk from one node only. ASE actually Reserves the disk on the SCSI bus level, making it impossible for another node to access it. If the two partitions were in different ASE services you could want to move one of them to another node, but not the other. This would be impossible since they MUST be accessed from the same node. This is the reason why ASE even doesn't allow that kind of configuration. [Posted by WWW Notes gateway] | |||||

I understand now. But it is hard to justify to let a file - like
a control file(only couple hundred butes) of Oracle to take the whole
4 GB disk. I can't put it into a file system because only raw RDR
service can be defined.

re .2
Of course you don't want to waste a rz29 for an Oracle control file.
Use LSM to cut the disk into as many small chunks you need.
PITFALL ALARM!
Make sure you use different LSM disk groups! Because if a DRD service
migrates it drags along the LSM volumes comprising that service and
that will also drag along the whole LSM disk group those volumes belong
to and that will migrate all disks with partitions in that LSM disk
group.
Hope this helps
