Large (>10MB) SOAP Responses Are Truncated in Oracle API Gateway (Doc ID 2245235.1)

Last updated on JANUARY 04, 2021

Applies to:

Oracle API Gateway - Version 11.1.2.1.0 and later
Information in this document applies to any platform.

Symptoms

Currently migrating from Oracle Enterprise Gateway 11.1.1.6.1 to Oracle API Gateway 11.1.2.4.0 SP4. After the upgrade, there is an issue with a service that returns a very large XML payload. 

When the response is returned from OAG, it is truncated to 10MB and the remaining data is discarded. 

The following error is seen in the gateway trace file.

ERROR
