- **To use JRE**: The 64-bit IR requires 64-bit JRE. You can find it from [here](https://go.microsoft.com/fwlink/?LinkId=808605).

- **To use JDK**: The 64-but IR requires 64-bit JDK 23. You can find it from [here](https://www.oracle.com/java/technologies/downloads/#jdk23-windows). Be sure to update the `JAVA_HOME` system variable to the root folder of the JDK 23 installation i.e. `C:\Program Files\Java\jdk-23`, and add the path to both the `C:\Program Files\Java\jdk-23\bin` and `C:\Program Files\Java\jdk-23\bin\server` folders to the `Path` system variable.

> If you copy data to/from Parquet format using Self-hosted Integration Runtime and hit error saying "An error occurred when invoking java, message: **java.lang.OutOfMemoryError:Java heap space**", you can add an environment variable `_JAVA_OPTIONS` in the machine that hosts the Self-hosted IR to adjust the min/max heap size for JVM to empower such copy, then rerun the pipeline.
