Hanging Sessions in SAP ITSmobile/Standalone SAP ITS Gateway

[Former Member]

Hi,

We have recently implemented SAP ITSmobile/Standalone SAP ITS gateway 6.20 (6200.1035.9507.7, build 1121051 - Single host) connected to LXE RDT device for warehouse operation.

In warehouse forklift operators quite often lose connection to Wireless access point,which is creating orphan sessions in background and not getting cleared sometimes from the system, we have to manually Clear(kill) the sessions .

I have introduced following parameters in SAP ITS instance in ALL SERVICES. pls let me know, is there any parameter need to be enforced to clear the hanging session. Apprecitete your help.

Parameters in SAP ITS Gateway Instance:

~disconnectonclose = 1

~timeout = 30

~usertimeout = 0

Also, I see following log entries in access log, what could be the reason for ???? in the access log ?

2011-07-11T16:23:03.431 00, s000000000A83DD00, IP 10.64.44.186, *zzits_r3_sp, , 2011-07-11T16:25:06.507 00, s0000000000000000, IP ???.???.???.???, command AgateShmGet:Proc:ITP 2011-07-11T16:25:06.523 00, s0000000000000000, IP ???.???.???.???, command AgateShmGet:Proc:ITP 2011-07-11T16:25:06.523 00, s0000000000000000, IP ???.???.???.???, command AgateShmGet:Proc:ITP 2011-07-11T16:25:06.523 00, s0000000000000000, IP ???.???.???.???, command AgateShmGet:peak:ITP 2011-07-11T16:25:06.539 00, s0000000000000000, IP ???.???.???.???, command AgateShmGet:Thrd:ITP:0 2011-07-11T16:25:06.554 00, s0000000000000000, IP ???.???.???.???, command AgateShmGet:Sess:ITP:0

Hello Soma,

With the ITS 6.20 you can use the ~timeout parameter to change the session timeout in minutes. Basically the value, in minutes, will determine when the session terminated after that period of inactivity. This can be changed on a per service level. So if you think the wireless connection is lost every 10 minutes and the users should have activity every 5 minutes then it is safe to change the ~timeout value to 10.

In the access.log the question marks (?) are when a request is made before there is user information, that would mostly be the logon page. The entries with "command" in it are requests from the ITS ADM instance.

Hi Edgar

Thank you, as per your suggestion I am going to reduce the value set for ~timeout parameter.
