Prepare the Storage on OCI
This document uses the EDG folder structure as reference, which uses both shared and private folders.
If your primary environment does not follow the exact EDG folder structure described in this document, then use the following guidelines:
- For shared folders: Use Oracle Cloud Infrastructure File Storage file systems. For the runtime shared folders, you can also use Oracle Database File System (see Learn More for more information).
- For private usage folders: Use Oracle Cloud Infrastructure Block Volumes or, alternatively, Oracle Cloud Infrastructure File Storage file systems mounted privately by each host.
Prepare the OCI File Storage
Provision the mount targets and file systems to create the Oracle Cloud Infrastructure File Storage service for the mid-tier hosts in Oracle Cloud Infrastructure (OCI).
If your OCI region has more than one Availability Domain and
you plan to distribute the mid-tier hosts between two Availability
Domains, then create a mount target in each Availability Domain.
Create and export the shared file systems (wlsdrconfig
,
wlsdrruntime
) in the mount target of the
Availability Domain where the Administration server will normally
run, and create and export the others file systems (wlsdrproducts1
and wlsdrproducts2
)
in the mount target of the Availability Domain where the host that
is going to mount it is located. For example, wlsproducts1
in
the mount target of the Availability Domain where APPHOST1 is located, and wlsdrproducts2
in the mount target of the Availability Domain where the APPHOST2 is located. For more
information, see Plan the Resources for the DR
Environment.
Note:
For the Terraform code to create these mount targets, file systems and exports, see Download Code.
Prepare the OCI Block Volumes
For the storage that is used privately by each host, (the private configuration such as node manager and MSERVER_HOME), you must provision at least one Block Volume per host. Provision each Block Volume in the same Availability Domain of the host that is going to mount it.
The table shows example values for creating the block volumes:
Block Volume | Availability Domain | Compartment | Size | Backup Policy |
---|---|---|---|---|
wlsdrBV1 | Same as the WebLogic Server mid-tier host 1 | HyDRCompmt | 50 GB | Select backup policy according to your business requirements |
wlsdrBV2 | Same as the WebLogic Server mid-tier host 2 | HyDRCompmt | 50 GB | Select backup policy according to your business requirements |
