Continentalclusters Version A.05.00 Release Notes
What’s In this Version
Chapter 1 7
• Logical data replication is also possible using the Oracle Standby
Database. Template files and additional information are included in
the Oracle Standby Database portion of the separately purchased
Enterprise Cluster Master Toolkit product. Other customer-selected
logical data replication solutions can be implemented as well.
• Cluster monitoring is carried out over WAN connections. You can use
any WAN connection; however, some data replication methods may
require high speed connections such as T1, T3, E3/ES or ATM leased
lines or switched lines.
NOTE Continentalclusters can co-exist with the Advanced Tape Services (ATS)
feature of Serviceguard. However, an ATS package must not be
configured as a Continentalclusters package. With ATS, a single tape
drive (or set of tape drives) is shared between two nodes within a cluster
of up to four nodes. All of the tape drives are located within a single data
center. If the power were to be lost, the tape drives would not be
accessible even if the package were to be failed over to the other data
center with a Continentalclusters package. Therefore, using ATS in a
Continentalclusters package does not make any sense.
