Resource Limits and Characteristics of Infrastructure Shapes

This article lists the resource limits and characteristics of Exadata Infrastructure resources for the different Exadata system models and configurations available for Oracle Autonomous Database.

Resource Limits

The following table lists the resource limits for dedicated Autonomous Database deployments on Oracle cloud and Exadata Cloud@Customer.

Note:

The limits listed in the following tables apply to all the Exadata Systems supported by a dedicated Autonomous Database. Exceptions (if any) are highlighted accordingly.

Enforced Resource Limits (Maximum)

Note:

The limits listed in the table below are only enforced on the Exadata systems deployed on Oracle cloud.
Resource Quarter Rack Half Rack Full Rack
Autonomous Databases 1000

(920 on Exadata X7 system)

2000

(1840 on Exadata X7 system)

4000

(3680 on Exadata X7 system)

Autonomous Container Databases 12 12 12

Recommended Resource Limits (Maximum)

Resource Quarter Rack Half Rack Full Rack
Autonomous Databases per Autonomous Container Database 200 200 200
Autonomous Databases per Autonomous Container Database with Autonomous Data Guard Configured 25 25 25

Note:

It is possible to provision more Autonomous Databases than those recommended in the above recommended limits table, especially with fractional OCPUs. However, this implies compromising the Service Level Objectives (SLOs) to return an application online following an unplanned outage or a planned maintenance activity. To know the SLO details for dedicated Autonomous Database deployments, see Availability Service Level Objectives (SLOs).

Limits for Autonomous Exadata VM Clusters on Exadata Cloud@Customer

On Exadata Cloud@Customer, you can create multiple Autonomous Exadata VM Clusters (AVMCs) on an Exadata Infrastructure resource. There are no hard limits on the number of AVMCs or Autonomous Container Databases (ACDs) you can provision on your Exadata Infrastructure. The AVMCs and ACDs have a minimum resource requirement, and you can create them as long as the minimum amount of resources is available.

To create an Autonomous Exadata VM Cluster, the minimum resources required per node are 5 OCPUs, 100GB Memory, 150GB Local Storage, and 3.25TB Exadata Storage. Similarly, the minimum resources needed per node to create an ACD are 2 OCPUs and 50GB Local Storage. As long as your Exadata Infrastructure has these minimum resources available, an AVMC and ACD can be created.

Exadata X9M-2 Systems

For dedicated Autonomous Databases deployed on Oracle Cloud, X9M-2 systems support elastic configurations instead of fixed shapes such as quarter rack, half rack, or full rack. X9M-2 systems are currently provisioned with a configuration equivalent to a quarter rack.

Should you need to provision an X9M-2 system with a different configuration, you have the flexibility to choose another value for database servers and storage servers within a valid range. The acceptable range of values is 2 to 32 for database servers and 3 to 64 for storage servers.

To provision an X9M-2 system successfully, the service limits for Exadata X9M Database Server Count and Exadata X9M Storage Server Count in your tenancy should be at least 2 and 3, respectively. Request a service limit increase from the Oracle Cloud Infrastructure console if required. Observe that the Exadata X9M Database Server Count and Exadata X9M Storage Server Count limits are defined as counts per availability domain. Refer to Requesting a Service Limit Increase for more details.

The table below lists the characteristics of an Exadata X9M-2 system on Oracle Cloud with its default database server and storage server settings.

Property Default Provisioning
Number of Compute Nodes 2
Total Maximum Number of Enabled CPU Cores 252
Total RAM Capacity (GB) 2,780
Persistent Memory (TB) 4.5
Number of Exadata Storage Servers 3
Maximum Database Size, No Local Backup (TB) 152

For more details, see the Dedicated Autonomous Database X9M data sheet.

For dedicated Autonomous Databases deployed on Exadata Cloud@Customer, you can select any of the following shapes while provisioning an X9M-2 system. The table below lists the characteristics of the Exadata X9M-2 systems available in Oracle Autonomous Database deployed on Exadata Cloud@Customer.

For more details, see the Oracle Exadata Database Service on Exadata Cloud@Customer X9M data sheet.

Exadata X8M-2 Systems

For dedicated Autonomous Databases deployed on Oracle Cloud, X8M-2 systems support elastic configurations instead of fixed shapes such as quarter rack, half rack, or full rack. X8M-2 systems are currently provisioned with a default configuration of 2 database servers and 3 storage servers that is equivalent to a quarter rack.

Should you need to provision an X8M-2 system with a different configuration, you have the flexibility to choose another value for database servers and storage servers within a valid range. The acceptable range of values is 2 to 32 for database servers and 3 to 64 for storage servers.

To provision an X8M-2 system successfully, the service limits for Exadata X8M Database Server Count and Exadata X8M Storage Server Count in your tenancy should be at least 2 and 3, respectively. Request a service limit increase from the Oracle Cloud Infrastructure console if required. Observe that the Exadata X8M Database Server Count and Exadata X8M Storage Server Count limits are defined as counts per availability domain. Refer to Requesting a Service Limit Increase for more details.
