Hi,
when we receive a message larger than 512k it splits into segment.
is this is possible(Through Queue Manager or Queue properties setting not through coding) to prevent message from segments.? |

The default maximum size for a single message is 4Mb. This can be increased to 100Mb for a single message.
So if you're getting segmentation at 512k it's something you've done locally in your code or your configuration to make that happen. You can prevent it by identifying & reversing it.

How can we change or where we can found the configuration of message size to changes the message behaviour.
and how can we prevent a message from segmentation with out changing in code. |

Your code must have been written to specifically allow segmentation, it's not allowed 'by default'.
So if the intent of the code is to use segmentation, why do you want to defeat that intent? |

Whereever you hold configuration for your code.

Youi can't. As I explained above, that limit is well below anything WMQ would balk at. So either you've configured your code to segment in that way or (this is my personal suspicion) your code has a 512k buffer somewhere and is automatically cutting up the data so it fits in the buffer.

What is the max msg size of your destination queue set at?
