On which layer MQSeries lie out of 7 layers of operating system
(eg: layers-- Network layer, application layer, session layer etc)
can someone help me on this.
Thanks in advance. |

Operating systems don't have 7 layers. Cakes and the ISO/OSI netowrk model have 7 layers. Is that what you are refering to? TCP/IP implies the 4-layer stack.
WMQ is an application. As needed, it calls for o/s services. Are you refering to the usual UNIX picture with the Kernel just above the Hardware Abstraction Layer (HAL from 2001) which is just above the hardware layer?

Good One....

But out of curiosity, since MQ leverages on TCP/LU 6.2/NetBIOS/SPX shouldn't it be in the Transport Layer? Or is it actually as high as the Application or the Presentation Layer? |

Application.
People mistakenly refer to MQ as a transport or protocol, but in OSI terms it is not. |

MQ uses various protocols for data transfer. But it's very much an application. What do you think your mail box sitting in which layer?

Absolutely. MQ is an application that is capable of using various protocalls for communication as per the case.

| MQ operates in the messaging layer. |

Do you mean Transport ?
As in OSI model (as stated earlier) there are layers :
Application Presentation Session Transport Network Data Physical
Or combination of [transport and network] layers ?

Not in the 7 layer OSI networking model.

We've given you the answer -why not accept it?
MQ is an application interface to the network. |

I'm going to take a guess here that faced with the graphic representation of the 4-layer tcp/ip stack or the 7-layer ISO/OSI stack, the post is asking where is WMQ.
Most entry-level IT/DP courses don't spend much time on the top layer (application), merely saying that's where applications run. I'm not sure why; since we're all employed to make sure the app layer functions correctly for the end-user.
WMQ is a server application. If/when WMQ definitions creates message channels, this is where the message channel agents make use of the network layers.
The messaging layer to which mqjeff refers is a layer of an application architectural model, not a the 4- or 7-layer network model.
