Component: Adapters

Resource Service Limit
Connectivity agent memory A minimum of 8 GB memory with 4 GB of heap size dedicated to the on-premise agent's Java Virtual Machine (JVM). To include any other processes on the host besides the agent, increase the physical memory to a value greater than 8 GB.
Connectivity agent message payloads
  • 10 MB through the use of compression

All connectivity-agent-enabled adapters

  • 50 MB as request
  • 50 MB as response

SOAP and REST adapters configured with connectivity agent

  • 50 MB (structured XML/JSON document) as response from SOAP/REST endpoints
  • 1 GB for attachments as part of a response from SOAP/REST endpoints
Structured payloads (JSON, XML) for connectivity-agent-based adapters
  • SOAP and REST: 50 MB
  • File and FTP invoke responses: 50 MB
  • Other protocols: 10 MB (for example, database, JMS, MQ, Kafka, and others)
Structured payloads for trigger connections and responses from invoke connections
  • Cloud endpoints: 100 MB (not using the connectivity agent)
  • Private endpoints: 100 MB
Binary (unstructured) payloads (for example, attachments, MTOM) for trigger connections and responses from invoke connections
  • 1 GB
Private endpoint support

Connecting to private endpoints is supported in a growing list of adapters.

See Adapters that Support Connecting to Private Endpoints in Using Integrations in Oracle Integration 3.

File Adapter (available only with the connectivity agent)

Read File operations:

  • 1 GB when used without a schema

Polling with a connectivity agent:

  • 50 MB

Download File operations:

  • 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.

For invoke configurations

Read File operations:

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

  • 100 MB for public internet-based endpoints
  • 100 MB for private endpoints

Download File operations:

  • 1 GB (when used with or without a connectivity agent)

Write File operations:

  • There is no limit
