GCOS 7 System Operator's Guide
After you enter the ENTER_RMOS command, you can specify which storage
techniques you wish to employ for storing incoming messages by specifying the
MODE parameter. If you specify MODE = FILE, you can either name an existing
Queued File with the correct allocation parameters or let RMOS create a temporary
file to be used during the RMOS session and deleted when it is over. The only
advantage of a permanent file is that you may locate it more easily. If you specify a
permanent file and RMOS is unable to open it, RMOS displays an error message
on your terminal and allocates a temporary file. For each link, one subfile is
created.
A change of operating mode implies terminating the current session and restarting a
new one.
When the file is full, RMOS automatically allocates additional space up to the
maximum file size limits. When these maximum values are reached, the RM53
message (UNABLE TO EXTEND RMOS FILE: SOME MESSAGES MAY BE
LOST) is issued. At this point, RMOS deletes the oldest messages in the largest
subfiles for links which have not been recently selected.
In the case of overflow, RMOS reduces the size of the largest subfiles and thus
equally distributes messages over all the subfiles. Use the SELECT or PURGE
command to create more space; then you can resume normal FILE Mode
processing.
Characteristics of the file used to store incoming link messages:
FILEFORM = BFAS
FILEORG = LINKQD
BLKSIZE = 6200
RECSIZE = 6196
RECFORM = VB
DELREC
COMPACT = NO
Any other parameters depend on size, location and number of links to be handled.
