Packet size determination

Former Member — Thu, 17 May 2007 19:06:15 GMT

Hi,

The flow of material data is

SAP - > TIBCO -> non-R/3 system

The packet size for port defined to send to TIBCO is 50 for ITEM_JA( outbound mode is collect idocs) and for english language is ITEM_EN is 1( Outbound mode is tranfer immediately).

SAP publisher stack size at TIBCO is 3000000 bytes.

Issue: During mass publishing of materials 500/ hour, the issue is coming while sending japaneese idocs for which segments are more for 50 idocs and TIBCO stack size is not able to accomodate.

Is it fine to reduce the pocket size at SAP side? If so howmuch do we need to reduce and what basis it is determined.

Is it fine to change the properties of ITEM_JA same as ITEM_EN?

Will there be any performance issues?

Thanks

Sree

Hi,

You can change the packet size at SAP, and there is no harm in it.

Only the problem is it will send more no. of packets than before, but it should not be an issue.

And reducing the packet size is totally depend on your system load and you have to take the decision between performance in the SAP system and TIBCO stack.

You can try by just reducing it to 30 or may be 40.

Hope it helps.

Reward points if helpful.

Hi,

As per packet size is consider, it not restricted , you can change the packet size.

I can just you two ways, to overcome the performance issues, if there are any.

1. You are updation is mass updation. If you are using mass updation, try to maitain the properties of both ITEM_JA and ITEM_EN as same, then there won't be any performance issuse.

Note : If they are both are interrelated.

2.If not , both there properties should be same as present, try to update with Indivival update. Cent % it won't give ant trouble either for any idocs.

Thanks
