Setting Up and Managing Disaster Recovery Sites 4-61
Section 4.4.1, Creating the Asymmetric Standby Site describes the basic steps for
creating an asymmetric topology. It does not describe in detail applicable concepts for setting up an asymmetric topology that were previously described for symmetric
topologies earlier in this chapter.
4.4.1 Creating the Asymmetric Standby Site
This section describes the high level steps for creating any type of asymmetric Oracle Fusion Middleware Disaster Recovery topology. The production site is the Oracle SOA
Suite enterprise deployment shown in Figure 4–2
. The standby site will be different from the production site.
To create an asymmetric topology:
1.
Design the production site and the standby site. Determine the resources that will be necessary at the standby site to ensure acceptable performance when the
standby site assumes the production role.
2. Create the Oracle Fusion Middleware Disaster Recovery production site by
performing these operations:
a. Create volumes on the production site’s shared storage system for the Oracle
Fusion Middleware instances that will be installed for the production site. For more information, see
Section 4.1.1, Directory Structure and Volume Design.
b. Create mount points and symbolic links on the production site hosts to the
Oracle home directories for the Oracle Fusion Middleware instances on the production site’s shared storage system volumes. Note that symbolic links are
required only in cases where the storage system does not guarantee consistent replication across multiple volumes; see
Section 3.2.3, Storage Replication for
more details about symbolic links. For more information about volume design, see
Section 4.1.1.1.1, Volume Design for Oracle SOA Suite.
c. Create mount points and symbolic links on the production site hosts to the
Oracle Central Inventory directories for the Oracle Fusion Middleware instances on the production site’s shared storage system volumes. Note that
symbolic links are required only in cases where the storage system does not guarantee consistent replication across multiple volumes; see
Section 3.2.3, Storage Replication
for more details about symbolic links. For more information about the Oracle Central Inventory directories, see
Section 3.2.2, Oracle Home and Oracle Inventory.
d. Create mount points and symbolic links on the production site hosts to the
static HTML pages directories for the Oracle HTTP Server instances on the production site’s shared storage system volumes, if applicable. Note that
symbolic links are required only in cases where the storage system does not guarantee consistent replication across multiple volumes; see
Section 3.2.3, Storage Replication
for more details about symbolic links.
e. Install the Oracle Fusion Middleware instances for the production site on the
