Implementation Options

Several reference solutions are presented to implement mid-tier replication with the replication technologies described earlier.

Since most applications use different types of storage, a complete replica solution normally requires a combination of them. For example, in a system that uses OCI Block Volumes for configuration and OCI File Storage file systems for runtime files, you must use both Block Volume replica and OCI File Storage replication.

The following implementations, including explanations and examples, are covered:

• OCI Block Volume replication
• OCI File Storage replication
• Rsync peer-to-peer
• Rsync with a central staging location
• Oracle Database File System (DBFS) replication

Each implementation includes the following sections:

• Set up replication

  Steps to set up the replication based on the replication technology and examples. The examples can include reference scripts, some of which were designed and tested for specific systems (for example, Oracle WebLogic). If they don’t apply to your system, use them as a reference and implement your own equivalent scripts.

• Validation

  Steps to make the replicated contents available in the secondary site. It only includes the steps related to the mid-tier artifacts. It doesn’t include the additional steps needed to make the secondary system ready, such as switchover, converting the standby database into a snapshot, or starting mid-tier processes in standby.

• Ongoing replication

  Guidelines for performing the replica on an ongoing basis once it has been set up and validated.
