158.0. "OA$MTI_LIMIT_LISTS Logical" by BEAGLE::WOOD (Are you sure this is the way?) Tue Mar 03 1992 13:35

    Hi All,

    There is currently a workshop running to update the ALL-IN-1 Start SDK
    for the new features of ALL-IN-1 IOS V3.0

    We've come across a logical which we can't fully explain;
    
    OA$MTI_LIMIT_LISTS
    
    RTFM is no help the manual states;
    
    "Define this logical to be 1 if you want to apply a maximum limit to
    the number of addressees for a message."
    
    Is there another logical (undocumented) to be defined to set the number
    of addressees.
    
    Many Thanks,
    Andy

158.1For compatability with pre-V2.3AIMTEC::PORTER_TTerry Porter, ALL-IN-1 Support, Atlanta CSCTue Mar 03 1992 15:0220
OA$MTI_LIMIT_LISTS is a switch that tells ALL-IN-1 if it should limit the
number of TOs and CCs so that the SDAF record is small enough to be handled
by a pre-V2.3 ALL-IN-1 system.

In V2.3 the maximum size of a SDAF record was increased by a factor of 512.
This allows many more attributes, the most popular ones being TOs and CCs.
The down-side of this is that if you build a mail message with a large number
of TOs and CCs and send it to a pre-V2.3 system then the recieving system
will not be able to handle the mail.

If this logical is set to 1 the maximum number of TOs and CCs is artificially
limited to about 800 (I can't remember the exact number) and if this logical
is set to 0 there is no limit on the number of TOs and CCs appart from the
fact that they must all fit into the SDAF (In practice this means a limit
somewhere in the region of 500,000 attributes, but the actual limit depends 
on the size of the attributes).

158.3Cos of V2.3KERNEL::HOULDINGJJill Houlding - Back in BasingstokeTue Mar 03 1992 15:1726
	Andy

	In ALL-IN-1 V2.3  there was a problem where if the total size of the 
	DAF attributes exceeded a certain number of bytes (I can't remember 
	the exact limit). This can be translated into "a problem with a large
	number of addressees on a message as these are held as attributes in 
	the DAF.

	This was fixed in ALL-IN-1 V2.4 when the total size of attributes was 
	increased. However, if a message with a large number of addressees is
	created in ALL-IN-1 V2.4 and sent to a recipient on an ALL-IN-1 V2.3 
	system various symptoms will be seen e.g Acc Vio in the Fetcher. 

	In order to restrict the number of addressees on a mail message so that
	it does not blow up a V2.3 system you can set the logical
	OA$MTI_LIMIT_LISTS on the ALL-IN-1 V2.4 system. There is no need to do 
	this if all the ALL-IN-1 systems in your network are at V2.4 or above as
	they can cope with a larger total attribute size.


	Hope this helps

	Cheers

Jill,

I thought that the maximum total attribute size increased with V2.3 not
V2.4 and therefore the logical should be set to 1 if you have pre-V2.3 
ALL-IN-1 systems on the network, but V2.3 and V2.4 can exchange mail
with a large number of attributes without any problem.
