So your unique message that can never, ever, be replicated is sent from your server to an intermediate server which then blows up with no chance of recovery - the message never makes it to the target server.

The OED also states for guarantee "...something that makes an outcome certain...", and for assured "...confident..."
I'll agree to differ on this one, otherwise I can see a long game of BB tennis ahead of us

This decision is highly influenced by fatherjack's signature....

Even Oracle is supported as both the Target and Source for Q Replication. So it works pretty good for you also |

Let's use the postal service as an example:
If I address a letter to an address on the 2nd floor above a vacant lot, the post person cannot deliver the letter. If the address is defective, the PS can NOT guarantee that the letter will be delivered as addressed. The PS can let you know that the letter wasn't delivered, and possibly return the letter to you, or deliver the letter to the dead-letter-office. This is WMQs assured delivery.

I also implemented it. It was overall Good solution.
We had seen some performence issue for BLOB processing from MQ to D/B.. Later we resolved it by making some Design changes for message processing. |

Hi Aditya,
Could you please tell me how many messages were moved between sites per day in your case. And if possible how many per minute, per hour.
Also, what issues did you face due to BLOBs and what was the change made to the design.
Thanks. |
