Requesting a Limit Increase for Database Resources

Learn how to request a service limit increase.

If you need to increase a service limit for a multicloud database service, you can open a request in the Oracle Cloud Infrastructure (OCI) Console. You might need to do this if you need to provision more database infrastructure than your current tenancy limits allow.

Prerequisites: To request a limits increase for your Oracle Database@Azure subscription, you need to know your Azure subscription's availability zone mapping for the Azure region where you want to increase limits. Note that mapping differs between Azure subscriptions, and therefore you need to find the mappng for the particular subscription you are using with Oracle Database@Azure. To get Azure availability zone mapping, follow the instructions in Requesting a Limit Increase for Database Resources.

In the Azure Cloud Shell output for availability zone mapping, copy the availabilityZoneMappings section of the output into a text file to use when requesting the limits increase in the OCI Console. For example:

{
   "availabilityZoneMappings": [
	 {
	   "logicalZone": "1",           <------EXAMPLE MAPPING, WILL DIFFER BY SUBSCRIPTION
	   "physicalZone": "eastus-az2"  <------EXAMPLE MAPPING, WILL DIFFER BY SUBSCRIPTION
	 },
	 {
	   "logicalZone": "2",
	   "physicalZone": "eastus-az3"
	 },
	 {
	   "logicalZone": "3",
	   "physicalZone": "eastus-az1"
	 }

You will paste this section of the output into Limit Increase screen in the OCI Console, as discussed in the following steps.

Open the Console, then select the region you want for the limit increase. See Get to Know the Console and Working in Regions for more information.
Open the navigation menu and select Governance & Administration.
Under Tenancy Management, select Limits, Quotas and Usage.
Select the following values:
- Service: Database
- Scope: Leave the default displayed OCI Availability domain. This field isn't required by Oracle Support to increase your Oracle Database@Azure limits in an Azure availability zone.
- Subscription: Select your Oracle Database@Azure subscription.
- Compartment: Select the root compartment for your OCI tenancy.
In the table of resource limits, note the Service Limit, Usage and Available values for the resource you need a limit increase for. For example, if you're interest in Exadata storage servers, the Service Limit displays the current maximum number of storage servers that you can provision in the selected Availability domain. The Usage value shows the number of storage servers you have already provisioned, and the Available value shows the number of servers you can still provision with the current service limit.
To open a service limit increase ticket, select the Actions menu ()for the row that displays the resource you're interested in, then select Open Support Request.
On the Support Options panel, select Request a Limit Increase.
In the Support Chat panel, select Limit Increase, then select Limit Increase again at the bottom of the displayed text.
On the Support Options page, select the Limit Increase tab.
Select the following values:
- Service Catagory: Database
- Resource: Select the resource that you want to increase limits for. For example: "Exadata X9M Database Server Count".
- Subscription: Enter the Oracle Database@Azure subscription in which you want to increase limits. The subscription ends with the string "ORACLEDBATAZURE".
In the Availability domains section, if you don't know which OCI Availability domain is mapped to the Azure availability zone where you want the limits increase, you can leave the default values as displayed.

Note that in this section of the Limits Increase screen, each OCI availability zone is represented by an identifier that includes the geographical location and the availability zone number. For example, OCI's Ashburn region availability domain 1 is represented as hqkx:US-ASHBURN-AD-1.
In the Reason for request field, enter the following:
- Your Azure subscription's availability zone mapping for the Azure region where you want limits increase. Note that if you use more than one Azure subscription, this mapping can differ for different Azure subscriptions.
- The physicalZone value for the Azure availability zone that you want to increase limits in.
- The new limit you are requesting for the Azure availability zone.
- Any extra instructions that you want Oracle Support to have for this request.
The following example shows the information Oracle Support needs for your limits increase. Note that the mapping shown in the example differs between subscriptions.

Example Reason for request:

In my Oracle Datagbase@Azure subscription, increase the service limit for Exadata X9M database server count to 25 for Azure physicalZone eastus-az2. My Azure subscription's availability zone mapping is the following:
```
{
   "availabilityZoneMappings": [
	 {
	   "logicalZone": "1",           
	   "physicalZone": "eastus-az2"  
	 },
	 {
	   "logicalZone": "2",
	   "physicalZone": "eastus-az3"
	 },
	 {
	   "logicalZone": "3",
	   "physicalZone": "eastus-az1"
	 }
```
Select Create Support Request.

Open the Console, then select the region you want for the limit increase. See Get to Know the Console and Working in Regions for more information.
Open the navigation menu and select Governance & Administration.
Under Tenancy Management, select Limits, Quotas and Usage.
Select the following values:
- Service: Database
- Scope: Pick the OCI Availability domain that you want to increase limits in.
- Subscription: Select your multicloud Oracle Database subscription.
- Compartment: Select the root compartment for your OCI tenancy.
In the table of resource limits, note the Service Limit, Usage and Available values for the resource you need a limit increase for. For example, if you're interest in Exadata storage servers, the Service Limit displays the current maximum number of storage servers that you can provision in the selected Availability domain. The Usage value shows the number of storage servers you have already provisioned, and the Available value shows the number of servers you can still provision with the current service limit.
To open a service limit increase ticket, select the Actions menu ()for the row that displays the resource you're interested in, then select Open Support Request.
On the Support Options panel, select Request a Limit Increase.
In the Support Chat panel, select Limit Increase, then select Limit Increase again at the bottom of the displayed text.
On the Support Options page, select the Limit Increase tab.
Select the following values:
- Service Catagory: Database
- Resource: Select the resource that you want to increase limits for. For example: "Exadata X9M Database Server Count".
- Subscription: Enter your multicloud Oracle Database subscription. For example, if you're using Oracle Database@AWS, pick the subscription that ends with the string "ORACLEDBATAWS".
In the Availability domains section, enter a new service limit value for the Availability domain that you want to increase the limit in. The number you enter will be the new maximum value for the limit. For example: If your current limit is 20, and you enter 25, your new limit will be 25 (an increase of 5).

If you don't know which Availability domain to select, use the first displayed Availability domain. For example: hqkx:US-ASHBURN-AD-1 is one of the three Availability domains for the OCI US East (Ashburn) region.
In the Reason for request field, enter the availability zone where you want the limit increase to take effect. Enter any extra instructions that you want Oracle Support to have for this request.
Select Create Support Request.
