Organizing the Configuration File

Figure 6 shows an excerpt from the global, coserver-specific, and storage-manager specific sections in a sample ONCONFIG file. This sample configuration uses eight nodes with a single coserver on each node.

The configuration parameters that Figure 6 shows generate the following dbspace names and pathnames for the root dbspaces:

coserver 1         rootdbs.1         /work/dbspaces/rootdbs_1
                  /work/dbspaces/mirror_1
...

coserver 8         rootdbs.8         /work/dbspaces/rootdbs_8
                  /work/dbspaces/mirror_8

Backups go to the storage manager on coserver 1.
