Service Limits

Review the following service limits for Oracle Integration 3 resources. A service limit is the quota or allowance set on a resource. You cannot change the service limits configured for your tenancy.

Oracle Cloud Infrastructure Console Service Limits

Resource Service Limit

Integration service instance count

200 instances per region.

Note: This value is the number of service instances you provision per region, and not the number of integration instances (for example, app driven orchestration and scheduled orchestration) that you activate and monitor under the Observability tab in Oracle Integration.

Instance creation

The ability to create instances outside your home region depends on several factors. See Restrictions.

Private endpoint limits

  • 1 private endpoint per instance

  • 1 subnet per private endpoint

Component: Adapters

Resource Service Limit
For structured payloads delivered on trigger connections or as a response from invoke connections 100 MB limit for cloud endpoints (not using the connectivity agent). The limit is 100 MB if the endpoint is enabled with a private endpoint.
For binary (unstructured) payloads (for example, attachments, MTOM) 1 GB limit for trigger connections and responses from invoke connections.
For connectivity agent-based adapters, the payload limits for structured payload (JSON, XML). 50 MB limit for SOAP and REST.

For file and FTP with the connectivity agent, the limit for an invoke response is 50 MB for structured payloads.

For any other protocol (for example, database, JMS, MQ, Kafka, and others), the payload limit is 10 MB for structured payloads.
File Adapter - file size Read File operation:
  • 1 GB when used without a schema (with the connectivity agent)
  • 50 MB when using a schema for transformation
  • 50 MB for a read operation with structured payload (The File Adapter is only available with connectivity agent.)

Polling with the connectivity agent: 50 MB

Download File operation: 1 GB

Note

The size of CSV files increases when translated into a message. Therefore, the file size must be less than 50 MB, so that the after-translation message size does not exceed 50 MB.
FTP Adapter - file size

For invoke configurations

Read File operation:

  • 1 GB when used without a schema (when used both with or without a connectivity agent).
  • 100 MB for cloud-based endpoints when using a schema for transformation.

Component: Integrations

Resource Service Limit
Active integrations limit 700.

This limit is enforced. See Activate an Integration in Using Integrations in Oracle Integration 3.

Integration invocation depth 16 invocations.

For example, a parent integration (scheduled integration) invokes a child integration (app-driven orchestration integration), which in turn recursively invokes the parent integration.

Integration entry points along the request execution path are counted towards the limit. When 16 is exceeded, it results in an error.
String size limit Restricted to 10,000 characters.

The limit is applicable to all variables of type string, including global variables. The limit is also applicable to all functions, including a concat function used inside an assign, stitch, or mapper.
Parallel action concurrency limits Parallel action branches independent of the integration type (synchronous, asynchronous, and so on) count towards the concurrency limits on synchronous requests.

For example. a parallel action with three branches needs two extra concurrency slots for the duration of the parallel action; one branch is counted towards the original flow already obtained.
Triggers (maximum number of concurrent requests)
  • Synchronous: 100.
  • Asynchronous: No limit (50 at a time can execute, the rest are queued).
Maximum number of integrations that can subscribe to events 20 integrations can subscribe to events per service instance.
Maximum number of tracking events per instance
  • 20,000 for non-error events
  • 30,000 for error events (extra 10,000 if events are associated with errors)
  • 2000 max error recorded

After those limits are reached, events are no longer recorded in OpenSearch, but they continue to be processed and the instance overall state is calculated. This ensures that the instance state is updated in all scenarios.

Maximum OpenSearch payload sizes The total payload size stored per instance in OpenSearch is limited to 25 MB. There is no limit for payloads stored in the Object Store. Only payloads under 32k are stored in OpenSearch.
Maximum duration for integration flows
  • Asynchronous: Six hours (The instance is marked as aborted due to deadline timeout.)
  • Scheduled: Six hours (The instance is marked as aborted due to deadline timeout.)
  • Synchronous: Five minutes (An HTTP 502 occurs.)
Stage file action (in orchestrated integrations) - file size

Read Entire File operation: 100 MB. For files greater than 100 MB, use the Read File in Segments operation.

Encrypt File operation: 1 GB.

Decrypt File operation: 1 GB.
Synchronous integration message timeout 300 seconds.

Synchronous integrations (integrations that return a response payload) return a timeout error if they run more than 300 seconds.
Oracle Integration Messaging - message size 10 MB.
Encode and decode file attachment content (mapper) The functions encodeReferenceToBase64(String reference) and decodeBase64ToReference(String base64Content) have a file size limit of 10 MB.
Lookup column length 1024 characters.
Notification action - attachments size
  • If using the default method: 2 MB.
  • If using your customer tenancy: A default value of 2 MB that can be increased until the maximum value supported by the Oracle Cloud Infrastructure Email Delivery Service is reached.

Both the email body and attachment are considered in calculating the total size.

See Configure Notification Emails and Email Delivery Service Capabilities and Limits.

Maximum number of outbound emails you can send from Oracle Integration in a rolling 24-hour window
  • If using the default method: 10,000 emails.
  • If using your customer tenancy: Sets your limit to the number allowed by the Oracle Cloud Infrastructure Email Delivery Service.

See Configure Notification Emails and Email Delivery Service Capabilities and Limits.

JavaScript execution timeout threshold 15 seconds.
JavaScript function maximum parameter support 20 parameters.
Maximum duration of an XSLT execution 120 seconds.
Concurrency
  • Synchronous concurrent request: 100.
  • Asynchronous concurrent executions: 50.

    Asynchronous concurrent execution includes scheduled + triggered + connectivity agent.
Number of concurrent instances of given scheduled integration 1 for scheduled and out-of-band and 1 for ad-hoc.
Where:
  • Out-of-band: A run now run associated with a schedule.
  • Ad-hoc: A run now run not associated with a schedule.
Tenant and user requests 100 requests per second per tenant and 20 requests per second per user.
Execution time threshold for long running scheduled integrations Terminated by Oracle Integration if integration exceeds 6 hours. See Execution Time Threshold for Long Running Scheduled Integrations in Using Integrations in Oracle Integration 3.
Maximum number of iterations to execute for a while loop 5000.

Note: There is no limit for a for-each loop.

Maximum number of iterations captured across all loops for a single instance ID for which tracking data is captured 1000.
Project limits
  • 100 integrations, 20 connections, 50 lookups, and 20 JavaScript libraries per project.
  • 50 deployments per project.
Deployments to Oracle Cloud Infrastructure API Gateway An Oracle Cloud Infrastructure API Gateway instance supports a maximum of 20 deployments. Each deployment can contain up to 50 routes. This provides you with a capacity of 1000 integration endpoints to which to deploy.
Maximum number of branches in a parallel action 5.
Tracking variable - value 8191 characters.
Instance data retention Retention is based on the trace level set during integration activation:
  • Production: 32 days
  • Audit: 8 days
  • Debug: 24 hours
Time window for recovering a failed integration instance that's recoverable The instance is recoverable until one of the following occurs:
  • It is aborted. This can happen due to integration deactivation.
  • It is successfully recovered or the recovery leads to a nonrecoverable error.
  • It is beyond its associated retention time, which is 32 days by default.
Activity stream displayable rows 5000 rows maximum are displayable when expanding the tree.
Total size of activity stream (REST response) No limit.
