Semding to MSMQ

Mary,

We have a few MQSeries interfaces.  There is some set-up required at the OS level (installation/configuration of the MQ software and queue definitions), and then the protocol configuration within Cloverleaf (NetConfig).  E-mail me and we can set-up a time to discuss.  Depending on what questions you (or a Sys Admin) may have, I may need to pull-in another resource.

MSMQ is not the same as MQ Series

MSMQ = a microsoft product

MQ Series = an IBM product

Cloverleaf has support for MQ Series.  It does not support MSMQ.

Mary.

We have a Clinical System, with MSMQ as its messaging backbone.

In our communication, the MSMQ sockets can only send or receive messages (with MLLP encapsulation).  

An MSMQ receiving socket will send a TCP ACK/NAK to indicate that all is OK or not.

An MSMQ sending socket expects a TCP ACK/NAK to indicate that all is OK or not.

We wrote a PDL for this and apart from windows issues with high volume and load, it works well.

We don’t, but it is possible In Cloverleaf to route ‘message ACKS’ to create a ‘full-duplex’ Cloverleaf sending thread.

Richard,

Are you saying the Clinical System is using MSMQ and MSMQ is capable of connecting directly to tcp/ip sockets?

Or is there some software on the Windows platform that sits between MSMQ and the sockets?

The reason I ask is we are exploring exchanging information directly with the MSMQ portion of BizTalk and we dod not know if MSMQ can directly talk to tcp/ip and what if anything more needs to be done.

Thanks

I don’t know the application configuration, but it uses MSMQ for all message queuing.  It may be a plugin that provides the TCP connectivity, all I know is that it requires MLLP encapsulation and only provides a TCP level (one character) ACK, which suggests its a generic rather than HL7 specific.

Richard,

Thanks for the info. I think you are correct it is probably a plug-in based on my reading.

All the best
