- We have QMgrA hosted on MQ for z/OS v.6
- I checked and my QMgrACHIN log does not contain text "CSQXGIP" (hence no Client Attachment Facility aka CAF)
- I can connect from my Windows laptop (with MQServer v6 installed) using both MQ Explorer and Visual Edit using a svrconn (not named 'SYSTEM.ADMIN.SVRCONN') that is on z/OS queue manager.
Questions:
- Should this be possible if Client Attachment Facility (CAF) is not installed on z/OS?
- Should this work but we are out of licensing compliance?
- Should I take Xanax and relax?

Well... I found part of my answer in previous post by Jeff Lowery...
"MQ Explorer doesn't require the CAF in order to manage/administer/explore a zOS qmgr.
It does need it if you want to establish a direct connection to the qmgr, instead of by way of another qmgr. (No, I don't know if ms0s will correctly detect the zOS qmgr type if it's an indirect connection).
This appears to be a question about a direct (i.e. client) connection, and therefore the zOS qmgr does need the CAF for this to function."
Question Remains: What about MQ Visual Edit? _________________ Make three correct guesses consecutively and you will establish a reputation as an expert. ~ Laurence J. Peter |

Given the fact that MQ V7 explictly will allow 5 client connections for admin purposes only without paying for the CAF license.
I can only think that some how on your system CAF is installed and working or someone is already paying for it.
I never understood the CAF / License at all, must be a mainframe thing to keep 'it' save from those clients...
better check with your z/os sw license person to be sure! _________________ Michael

The mainframe CAF is superb, we use it as much as possible and it's allowed us to remove a number of distributed queue managers.
It's made our MQ topology much simpler, more reliable and I highly recommend it. We have 3500 MQ clients on our main mainframe and I never hear about any issues with them.
The overhead of messages arriving via client channels is actually slightly less than from other queue managers (as we measured it). |

In the future we may need CAF. Right now we use the concentrator (gateway) approach.
I am just trying to figure out if we have CAF installed here and, if not, why do some things work that I would consider clients (like MQ Visual Edit).
This all came to the forefront when I I was reading about MQ v7 on z/OS and the paper was talking about a limit of 5 administration client connects to z/OS MQ and they must be over SYSTEM.ADMIN.SVRCONN.
If I can currently do this against z/OS MQ v6 without CAF, I question if IBM is limiting client conns in v7 to manufacture a marketing opportunity.
My next stop is 1) MF Tech Svcs and 2) IBM sales rep

I am an idiot, but lets keep that between us...
My statement "I checked and my QMgrACHIN log does not contain text "CSQXGIP" (hence no Client Attachment Facility aka CAF)" was false...
I was checking the daggone MSTR log. _________________ Make three correct guesses consecutively and you will establish a reputation as an expert. ~ Laurence J. Peter |

fyi MQ 7 allows up to 5 free MQ client connections without requiring CAF to be installed. Can't remember if that's per QM or something at the system level. _________________ Peter Potkay

per qm.
actually it's 5 for MQ's admin channel, and a further 5 for message broker's config mgr connection. Provided, in both cases, you're using the default svrconn channel names. |

I know that this is an old posting, but I was searching for info on whether or not you had to install the z/OS Client Attachment Feature on MQ7 to use the limited 5 channel connections for administration. I am in the process of installing MQ 7 on z/OS and needed to know if I need to install CAF. We are not licensed for it. I called my IBM rep yesterday and he told me 'yes', that they trusted you. So we ordered it. I read on this post that you do not have to have the CAF installed. What is the correct answer, need to install it or not?
Thanks |

If you intend to have WMQ client-bindings type apps connect to z/OS qmgrs you need CAF.
At last read, CAF remains a licensed product. IBM and some other vendors view mainframers as adults, and expect adult behavior - like only installing and using products for which you are licensed. _________________ I like deadlines. I like to wave as they pass by.

If you only need up to 5 concurrent client channels AND they are to be used for MQExplorer or the ToolKit -only- AND you are going to use the default svrconn channel names, then no CAF is needed in MQ 7.0. I don't know this from personal experience, since we have the CAF here, but that is my understanding from the MQ Conferance and confirmed here by markt, who knows. _________________ Peter Potkay
