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)
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:
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).
