Continentalclusters Version A.06.00 Release Notes
What’s In this Version
Chapter 18
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 Enterprise Cluster
Master Toolkit product (a separately purchased product). Other
customer-selected logical data replication solutions can be
implemented as well.
Cluster monitoring is carried out over LAN or WAN connections. Use
any LAN or 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 is not practical.
Support for Cluster File System and Cluster Volume Manager
Recovery
Continentalclusters environment now supports recovering applications
running as Serviceguard packages that use Veritas Cluster File System
(CFS) 4.1 or Veritas Cluster Volume Manager (CVM) 4.1 from Symantec
for storage management. The application package must have
dependencies defined with the corresponding CFS Mount Point
Multi-node package (MNP) or CVM Disk Group MNP. This feature is
implemented using the /etc/cmconcl/ccrac/ccrac.config file.
Prior to Continentalcluster A.06.00, the ccrac.config file was used for
Oracle RAC configurations with SLVM or CVM 3.5 for storage
management. Starting with Continentalcluster A.06.00, the
ccrac.config file can also be used to configure Oracle RAC
configuration with CVM 4.1 or CFS 4.1 for storage management. In
addition, as a workaround, the ccrac.config file can be used to
configure single instance application with CVM 4.1 and CFS 4.1. For
