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

158.1	For compatability with pre-V2.3	AIMTEC::PORTER_T	Terry Porter, ALL-IN-1 Support, Atlanta CSC	`Tue Mar 03 1992 15:02`	20
	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).

	The mist clears...... Many Thanks, Cheers, Andy
158.3	Cos of V2.3	KERNEL::HOULDINGJ	Jill Houlding - Back in Basingstoke	`Tue Mar 03 1992 15:17`	26
	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

158.5	And a discrepancy	AIMTEC::PORTER_T	Terry Porter, ALL-IN-1 Support, Atlanta CSC	`Tue Mar 03 1992 22:44`	8
	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. Terry
