Configuration Considerations

Volumes Eligible for Replication

Generally, include the following critical volumes in the Sun SNDR configuration:

Database and database management system (DBMS) logs (the total database or online DBMS log)

Access control files

You can exclude volumes from the Sun SNDR software configuration if they can be reconstructed at the recovery site or if they seldom change:

Temporary volumes (such as those used in sort operations)

Spool files

Paging volumes

When selecting a volume to be used in the Sun SNDR software volume set, ensure that volume does not contain disk label private areas (for example, slice 2 on a Solaris operating environment-formatted volume). The disk label region is contained in the first sectors of cylinder 0 of a disk. The safest method is to ensure that cylinder 0 is not part of any logical volume that is replicated (except for volumes under Veritas Volume Manager control, where cylinder 0 can be part of a logical volume that is replicated).
