Begin Batch

When a Begin Batch message is received, the temporary directory DR_TMP_DIR is first created in the target directory, if not already created. Then, a target file is created and opened in the temporary directory.

End Batch

When an End Batch message is received, the target file in DR_TMP_DIR is closed and, finally, the file is moved from the temporary directory to the target directory.

Cancel Batch

If a Cancel Batch message is received, the target file is removed from the DR_TMP_DIR directory.
