Understanding Request Timeouts in Integration and OData Provider

Request timeouts are a crucial aspect of integration and OData provider services, ensuring that connections are established efficiently and server resources are utilized optimally. In this article, we will delve into the various timeout values used in IFS (Infor Financial Solutions) and OData Provider, including their roles, default settings, and overrides.

General Integration Timeout

IFS_INTEGRATION_STATEMENT_TIMEOUT is a general integration timeout for any given request. This value defines the maximum time allowed for an integration process to complete its tasks. The default setting is 30 minutes.

Max Query Timeout

IFS_INTEGRATION_MAX_QUERY_TIMEOUT sets the maximum value for integration timeouts of data retrieving requests. This ensures that queries do not exceed their allocated time, preventing potential delays or errors.

Query Timeout

IFS_INTEGRATION_QUERY_TIMEOUT defines the default integration timeout for data retrieving requests. This value can be overridden using the wait property in HTTP preference headers.

Batch Requests and Individual Request Timeouts

In batch requests, each part (individual request) is executed with a timeout of IFS_STATEMENT_TIMEOUT, regardless of its nature (data retrieval or modification). If the request is a data retrieval query, the wait preference must be less than IFS_MAX_QUERY_TIMEOUT. Otherwise, IFS_MAX_QUERY_TIMEOUT is used as the request timeout. For data modifying requests, the wait preference must be less than IFS_STATEMENT_TIMEOUT.

HTTP Header and Timeout Overriding

The wait property in HTTP preference headers allows for overriding these parameter values on a per-request basis. This provides flexibility and control over timeouts for specific requests.

OData Provider and Connection Timeouts

In OData Provider, connection timeouts are used to establish connections between processes. The maximum amount of time allowed for setting up a connection is set by the `IFS_CONNECTION_TIMEOUT` value (in milliseconds). A socket timeout is also used when waiting for individual packets, with a default setting of 15 minutes.

req setTimeout() and RequestTimeout

The `req.setTimeout()` method sets the timeout on the req object. However, this may not be suitable for large file uploads or long-running requests. Instead, you can set the request timeout using the `Server.requestTimeout` property, which defaults to 5 minutes.

In conclusion, understanding request timeouts in IFS and OData Provider is crucial for optimizing integration processes and improving server resource utilization. By setting these values correctly, you can ensure efficient communication between systems and provide a better user experience.
