Serviceguard and Oracle Cluster (CRS)

[Yarek]

Hello Experts!

We would like to build the environment where Oracle instances will be working in 4-node cluster:

Four HP-UX 11.31
Oracle 10g, ASM on rlvol's


We can use only CRS (Oracle cluster) or integrate CRS with Serviceguard using Serviceguard Extension for RAC.

What would be the advantages of integration Oracle's cluster CRS with Serviceguard?
ServiceGuard will allow us for LAN switching in case of failure (redundant cards) but we could use AutoPort Aggregation instead of SG?
I know that ServiceGuard would allow us to use CLUSTER_INTERCONNECT_SUBNET parameter for specific switching LANs responsible for RAC interconnect. But is there any other advantage?

Thanks in advance for advices!

ragards,

Shalom,

Other Service Guard Advantages:

HP has better quality assurance and contrary to Oracle it was developed specifically for HP-UX. Oracle often has issues running on HP-UX due to less than complete quality assurance testing.

APA is a good option but costs the same as Service Guard.

A potential issue is how SG works with ASM.

There is an argument in favor of CRS. Less complexity.

With CRS and SG there is more software, more places for things to go wrong and interfere with one and other.

With CRS alone there is less complexity. Something to think about.
