Appendix G. Estimating the Size of the Physical File for a Message Queue

The UAP can use a disk queue for the input/output queue for exchanging logical messages under the message control facility (TP1/Message Control). The disk queue causes the logical messages to be written on a physical file for message queue. The record length and number of records specified in the queinit command determine the size of this file. This section provides the estimation formulae for the physical file for message queue.
