Hi ,

We have business requirements,where the Maximum message size that needs

to be sent or received from around 25 to 30MB usig JMS XI channels.

But, "Note 856346 - J2EE JMS Adapter: Frequently Asked Questions (FAQ)"

specifies as below,

2.12)What are the message size restrictions in 640/700 release and also

710 releases?

Answer: The maximum message size for 640/700 releases is "10MB"

Please let us know,

1) If you see any issues with JMS XI Adapter handling 30MB messages in

Production systems.

2) If 30MB is huge, what is the maximum permissible message size

greater than 10MB as break point.

regards,

Amit

Hi Amit,

i DONT THINK there is any improvement in message size handling by JMS Adapter PI7.1,10 MB is the size.are you sure you are going to retrieve more than 10MB file from MQ??

my advice to you write JAVA proxy to connect MQ and to retrieve message,using JAVA Proxy we can...even we can trasfer more than 10 mb messages.

but my suggestion is dealing with 10 mb messages not adviceble , better to slit the messages,other wise you may face JAVA stack issues.

Raj

SAP note says that the message size is configurable in SAP PI7.1 for JMS

1) If you see any issues with JMS XI Adapter handling 30MB messages in 
Production systems.

If message size beyond 10MB then the message wont come to SXMB_MONI itself.....may be even in CC monitoring there may not be an entry....you mentioned Production Systems.....did you checked in Dev? The behavior wont change from Dev to Prod.

2) If 30MB is huge, what is the maximum permissible message size 
greater than 10MB as break point. 

10MB itself is the limit...anything above that wont be processed.

Hi Abhishek,

can please tell why this will not appear in MONI.

> If message size beyond 10MB then the message wont come to SXMB_MONI itself.....may be even in CC monitoring there may not be an entry....you mentioned Production Systems.....did you checked in Dev? The behavior wont change from Dev to Prod.

now just consider if we increase the total size of the messages in the master queue server property

then is it possible to pass 30 MB message or not .

Amit .

The message will come in Moni only when the adapter processes it first (sender.....same logic for receiver)....so when the adapter itself does not support more than 10MB it wont forward it and hence you wont get a log of it.

Not sure.....but the message size can be increased in 7.1
