如何增加Azure托管的集成运行时JVM堆内存 [英] How to Increase Azure-hosted Integration Runtime JVM Heap Memory

问题描述

We are using Azure Data Factories to upload SQL data (stored in ORC files) from Azure Data Lake into Azure Data Warehouse. We keep getting the following error on one specific table:

"errorCode": "2200",
"message": "ErrorCode=UserErrorJavaInvocationException,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=An error happened when invoking java, message: java.lang.OutOfMemoryError:Java heap space.,Source=Microsoft.DataTransfer.Richfile.OrcTransferPlugin,''Type=Microsoft.DataTransfer.Richfile.JniExt.JavaBridgeException,Message=,Source=Microsoft.DataTransfer.Richfile.HiveOrcBridge,'",
"failureType": "UserError",
"target": "ADLToADWCopy"

This table gave the same error when we uploaded from the source SQL DB into Azure Data Lake and we were able to resolve that by tweaking the JVM memory allocation on the self-hosted Integration Runtime machine:

setx _JAVA_OPTIONS "-Xms256m -Xmx16g" /M

Is there a way to pass something similar to the Azure-hosted Integration Runtime?

推荐答案

你好，

我看到的用于Azure托管IR的唯一配置是位置:

The only configuration I see for Azure managed IRs are the location:
