WebSphere and MQ Client installed are installed in Linux box. MQ client connects to remote MQ Server. I am using a simple P2P application.

I have a 2 broad items to discuss:

Item 1: Msg in queue is persistent and crashing of remote MQ server. There
are 2 scenarios:
A) Persistent msg is put in queue and remote MQ server crashes before that msg is consumed. Will this msg be available after MQ server comes back up?

B) If remote MQ server is down, can the client still continue putting persistent messages in queue using MQ client in WebSphere box? Or, if the remote MQ server is down, client will get an exception if it tries to put msg in the queue?

What are answers for the above 2 scenarios?

Item 2: MQ Client or light weight MQ Server in WebSphere box. There are also 2 scenarios for this item:

A) Install light weight MQ server in WebSphere box and light weight MQ server connects to remote MQ server. Is there any light weight MQ server that can be installed in WebSphere box?

B) Install MQ client in WebSphere box and MQ client connects to multiple MQ servers configured in a cluster. Can someone refer me to a document that shows how to configure MQ client in WebSphere box to connect to multple MQ servers configred in a cluster?

I have my opinion. But also want to know what the the preferred architecture and pros and cons of the above 2 architectures.

Thanks in advance.
