Features Released in Software Version 3.0.2-b776803 (December 2022)
Platform Images
Platform images are available to all compartments in all tenancies without being imported to any compartment by users.
The following platform images are delivered with this Private Cloud Appliance release:
| Oracle Linux 8 |
|
| Oracle Linux 7.9 |
|
| Oracle Solaris 11.4 |
|
New platform images are delivered through Private Cloud Appliance installation, upgrade, and patch.
Important:
The Service Enclave administrator must import platform images after Private Cloud Appliance installation and should import platform images after every upgrade and patch in case new images were delivered. See "Providing Platform Images" in Hardware Administration in the Oracle Private Cloud Appliance Administrator Guide.Instance Backup and Restore
Oracle Private Cloud Appliance provides API commands that enable you to back up instances. The commands are flexible to suit a variety of use cases, including:
-
Back up instances and any attached block volumes.
-
Store the backups on another server for safekeeping.
-
Restore a faulty instance and any attached block volumes.
-
Use the backup to create matching instances.
-
Use the backup and restore feature to migrate instances to another tenancy, or to another appliance.
Note:
The maximum recommended object size supported is 10TB of total data and the maximum recommended object part size in a multipart upload is 5 GB.
For details see Instance Backup and Restore in the Oracle Private Cloud Appliance Concepts Guide and Backing Up and Restoring an Instance in the Oracle Private Cloud Appliance User Guide.
Instance Shape Update
When you update an instance, you can change the shape. You can change from any shape to any other shape. If the flexible shape is specified, you can change the shape configuration. For more information, see "Updating an Instance" in Compute Instance Deployment in the Oracle Private Cloud Appliance User Guide.
Enhanced Compute Instance Availability
If a compute node is lost due to a failure, a new reboot migration process is invoked. Its purpose is to evacuate compute instances to other compute nodes. Fault domain preference is strictly enforced with instance migration. If a compute instance cannot be migrated to another compute node in the same fault domain due to insufficient capacity, the instance is stopped and must be restarted manually.
File System Clones
You can use the OCI CLI to create file system clones. A clone is a new file system that is created from a snapshot of an existing file system. Snapshots preserve the state of the data of a file system at a particular point in time. If you take snapshots of a file system at regular intervals, you can create clones of the file system as it existed at multiple points in its lifetime.
Cloned file systems are managed in the same way that any other file system is managed. See the File System Storage chapter in the Oracle Private Cloud Appliance User Guide.
Tags for Specifying Certain Property Values
Private Cloud Appliance provides defined tags that enable you to set values for some properties. Applying these tags is the only way to set these particular properties.
The following defined tags are in the OraclePCA tag namespace.
Note:
Do not create your own tags in the OraclePCA tag namespace.| Resource, Operation | Tag Name | Values |
|---|---|---|
|
Block volume, create and update |
logBias |
LATENCY, THROUGHPUT |
|
secondaryCache |
ALL, METADATA, NONE |
|

File system, create |
databaseRecordSize |
512, 1024, 2048, 4096, 8192, 16384, 32768, 65536, 131072, 262144, 524288, 1048576 |
You must use the OCI CLI to set these tags. See the OCI CLI procedures in "Working with Resource Tags" in Resource Tag Management in the Oracle Private Cloud Appliance User Guide.
For examples, see "Creating a Block Volume" in Block Volume Storage in the Oracle Private Cloud Appliance User Guide and "Creating a File System" in File System Storage in the Oracle Private Cloud Appliance User Guide.
Capacity Monitoring
Administrators have direct access to the current consumption of key physical resources: CPU, memory and storage space. For more information, see "Monitoring System Capacity" in the chapter Status and Health Monitoring of the Oracle Private Cloud Appliance Administrator Guide.
Full Administration Network Segregation
In an environment with elevated security requirements, you can optionally segregate administrative appliance access from the data traffic. The administration network physically separates configuration and management traffic from the operational activity on the data network. In this configuration, only the administration network provides access to the Service Enclave, which includes the monitoring, metrics collection and alerting services, the API service, and all component management interfaces.
Service Request Diagnostic Data
If the Private Cloud Appliance is registered for Oracle Auto Service Request (ASR), certain hardware failures cause a service request and diagnostic data to be automatically sent to Oracle support. The collection of diagnostic data is also called a support bundle. A Service Enclave administrator can also create and send a service request and supporting diagnostic data separate from ASR. For more information about ASR and support bundles, see Status and Health Monitoring in the Oracle Private Cloud Appliance Administrator Guide.
