7015.0. "SNALU62-E-EXCMAX" by MDR01::VENTURA (MCS Madrid) Wed Feb 19 1997 08:31

	Hi, 
	I have a customer with SNA APPC/LU6.2 V3.0 ECO 6 for Digital UNIX
on a peer server. 
	He has configured 3 independent LU's with a "local maximum
session limit for this mode" to 32 and now he needs to increase this number to
a higher limit.

	I have tried to increase this number trought lu62_config to 64 but I
have got the following error:

	SNALU62-E-EXCMAX, request exceeds maximum allowed

	Anybody knows which is the limit of this parameter and if it can be
changed or maybe it depends of any other system parameter (memory, etc.)?.

	Regards

7015.1Look at the local LU session limitedsclu::GARRODIBM Interconnect EngineeringWed Feb 19 1997 10:008
    Re .0
    
    There is a session limit on the local LU as well. You cannot exceed
    that when setting the session limit for an individual mode. You need
    to first increase the local LU session limit before upping the mode
    session limit.

According to the architecure (ie. TPRM), the return code:

    SNALU62-E-EXCMAX, request exceeds maximum allowed

is _not_ for the the sum of all the source (ie. local) LU's session limit
(as set on the DEFINE_LOCAL_LU verb.)  LU_SESSION_LIMIT_EXCEEDED is 
what should be returned in this case.

7015.3The real reasonEDSCLU::GARRODIBM Interconnect EngineeringWed Feb 19 1997 13:1221
    Please ignore my reply in .1. It is incorrect. Here is the real reason
    you are getting the error.
    
    You cannot change the mode's local_max_session_limit while the
    negotiated session limit is non zero. You first need to RESET the
    session limit on the mode before upping the local_max_session_limit on
    the mode.
    
    After doing that use change session limit to put it back where you want
    it.
    
    Basically DEFINE_MODE ignores all parameters for an already existing LU
    (except for CONWINNER_AUTO_ACTIVATE_LIMIT) if there is currently a non
    (LU,mode) session limit and count for the mode name.
    
    The TPRM says that we should return an error if extra parameters are
    supplied. But currently the code just ignores the extra parameters.
    I'm not sure as to exactly why I'll have to ask the product's
    designer/author.
