Enabling large queues

WebSphere MQ supports queues larger than 2 GB. On Windows systems, support for large files is available without any additional enablement. On AIX, HP-UX, Linux(R), and Solaris systems, you need to explicitly enable large file support before you can create queue files larger than 2 GB. See your operating system documentation for information on how to do this.

Some utilities, such as tar, cannot cope with files greater than 2 GB. Before enabling large file support, check your operating system documentation for information on restrictions on utilities you use.
