Conclusion
Using SGeRAC Toolkit with multi-node packages and simple package dependencies provides a
uniform, intuitive, and easy-to-manage method to:
• co-ordinate between SGeRAC and Oracle Clusterware
• manage all the storage options supported by SGeRAC - CFS, SLVM, CVM , ASM over SLVM and
ASM over raw device (on HP-UX 11i v3)
Although the concepts of resource dependency and resource aggregation delivered by SGeRAC with
the multi-node package and simple package dependency features are present in some form or other
in other clusterware products – including Oracle Clusterware – the framework provided by SGeRAC
is unique due to the high level of multi-vendor (Oracle, Symantec, HP) and multi-storage platform
(CFS, SLVM, CVM, ASM over SLVM, ASM over raw device) integration it offers.
