The JES put/get timeout is used when the FTP client performs a GET with a source and a target name. The source job is submitted to JES. The server waits until the JES PutGet timeout expires or until the job completes. If the job completes, it stores the output in the target name file. If the job does not complete, the FTP client displays a reply to the end user.
Set the JES timeout value high enough for most jobs to complete within the specified time but not so high (for example, 86400) that end users wait excessive amounts of time for job completion.
