Load Balancing via Cloverleaf

[Robert Milfajt]

We’re running Cloverleaf 6.1.1 on AIX. The scenario is that we have Cerner iBus to send device data to Epic.  However, Epic has a performance limit that 1000 devices can connect to a single device interface.  iBus has more than that sending data.

Has anyone encountered this type of situation?  If so, how did you deal with it?

I’m thinking, creating some type of load balancing algorithm in either TrxID, or trying to find some data point, perhaps room/bed (but that would be quite a large table to maintain in Cloverleaf) to route data.

Any ideas, suggestions or real life experiences would be appreciated.

Thanks,

I think you’re spot on with the trxid proc; We’ve used a trxid proc before that looked at the first two characters of PV1-3.1 since our sending system had the device identifier begin with a campus identifier.  Hope this helps so you wouldn’t need to maintain a large table.

The closest I got to something like this was trying to load 180 million results in Epic for a conversion. I had to a trx tclproc and used the digit from the MRN to route it the message to one of the 10 threads I used to send data to Epic. I think something similar would work for you.

I may need to do something similar, but I’m still figuring out tcl (or at least the right data structures to use within Cloverleaf).  

I know this is an older post, but does anyone have a sample proc they can share?
