Hello,
this is my first posting in this forum.
My question is.
It is possible to configure a SDR-Channel to another QMGR on a specified IP-Address?
My problem is, that I have to use another IP than the default of the Solaris-System, because I have to use a logical IP while this is only allowed by the firewall.
Kind regards
Michael

Are you talking about a normal sender channel? You can specify any address you like in that for the target of the channel and it's resolved & routed by the magic of IP.
Please also post what version of MQ you're using. Please also correct me f I've misunderstood your question.

I would not use the IP address just because of the problem you are describing.
You should be able to use a DNS name. The address resolution then happens in the network layer.
Enjoy

Providing hmh isn't using 5.3. That parameter is new in 6.0 (hence my question about version).

Hi,
sorry, but my question might be a little wrong.
I have a sender channel and I reached the destination QMGR with the IP/DNS defined in CONAME of the SDR-Channel.
My problem is, that the firewall blocked my packets, because these are send via the first interface of the SUN, but allowed is only the logical IP of the second interface.
The connection works, if the IP of the primary interface is open on the FW, but I want that MQ will use the locigal IP as senderaddress so the FW will block the primary interface.
My Version is MQ 5.3.11.
Kind regards
Michael

Ummm.
It's valid in v5.3.. http://publibfp.boulder.ibm.com/epubs/html/csqzaj09/csqzaj0910.htm#HDRDEFCH

LOCLADDR(string)
Local communications address for the channel. Use this parameter if you want a channel to use a particular IP address, port, or port range for outbound communications. This might be useful in recovery scenarios where a channel is restarted on a different TCP/IP stack.
This parameter is valid only for channels with a transport type (TRPTYPE) of TCP. If TRPTYPE is not TCP, the data is ignored and no error message is issued. The value is the optional IP address and optional port or port range used for outbound TCP/IP communications. The format for this information is as follows:
LOCLADDR([ip-addr][(low-port[,high-port])])
where ip-addr is specified in dotted decimal or alphanumeric form, and low-port and high-port are port numbers enclosed in parentheses. All are optional.
Table 2 shows how the LOCLADDR parameter can be used:
Table 2. Examples of how the LOCLADDR parameter can be used
LOCLADDR Meaning
9.20.4.98 Channel binds to this address locally
9.20.4.98(1000) Channel binds to this address and port 1000 locally
9.20.4.98(1000,2000) Channel binds to this address and uses a port in the range 1000 to 2000 locally
(1000) Channel binds to port 1000 locally
(1000,2000) Channel binds to port in range 1000 to 2000 locally
This parameter is valid only for channels with a channel type (CHLTYPE) of SDR, SVR, RQSTR, CLNTCONN, CLUSSDR, or CLUSRCVR.
Note:
Even though this parameter is similar in form to CONNAME, it should not be confused with it. The LOCLADDR parameter specifies the characteristics of the local communications, whereas the CONNAME parameter specifies how to reach a remote queue manager.

It's a double dose of sackcloth and ashes for me tonight. 
I'll also cancel the purging and beating with hazel twigs; I just don't deserve it....
Apologies for spreading confusion and misinformation on the forum.

I'm sure, however, you still know the difference between the MQMD and the transmission header...

Ignore me, listen to everyone else and look up LOCLADDR as recommended.

At this moment, I'm not counting on it. I dread to think what my coffee was spiked with this morning (though I have a list of suspects in mind) but there's some really dodgy information coming out of my head and poluting this forum.
Of course, there's the alarming posibility my coffee wasn't spiked.... 
Transmission header - that's got the mcd information in it, right?

Thanks a lot.
This was ist.
alter channel(CHANNELNAME) CHLTYPE(SDR) +
LOCLADDR('logical address')

9.20.4.98(1000,2000) Channel binds to this address and uses a port in the range 1000 to 2000 locally
based on the same topic, can some explain how the above works ?
i.e on what port can listner be started based on the above numbers ? |

Localaddr has nothing to do with listeners. Listener ports are used to bind reciever channels - and the documentation clearly says that LOCALADDR is not valid for RCVRs. It's only valid for CLUSRCVrs because CLUSRCVrs are used as models for CLUSSDRs .

Jeff thanks for the reply,
I was confused with the conname and locaaddress, the doucmentation says excatly not to be ! the more I look the more I get confused,
9.20.4.98(1000) Channel binds to this address and port 1000 locally
9.20.4.98(1000,2000) Channel binds to this address and uses a port in the range 1000 to 2000 locally
So for a simple Sender , recevier channles , why there is a range ? |
