About Using Storage Groups
Siebel eBusiness Applications require one storage group for indexes and one storage group for tables (data). Before performing your installation, ask your DBA to provide you with one storage group name for each. You can use the same name for data and indexes, or you can use different names. You can set up storage group usage in any way that makes sense for your deployment.
See Allocating Space for Buffer Pools and Storage Groups for an example of storage group definitions.
