Sun Microsystems 3 manual Configuration Considerations, Volumes Eligible for Replication

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).
