Design in PI7.31

Hi Experts,

I am new to PI 7.31 version.

Recently we have migrated all interfaces from PI 7.0 to PI 7.31.

One of the interface is as below which was designed in PI 7.0

1) Async input from JMS

2) PI sends sync call to ECC and gets response

3) Response is sent to source Asynchronously through JMS

Async/Sync is implemented using BPM.

This keeps failing every month because the messages don’t reach in time as there is two middleware involved (PI and EI).

So client wants this is to be redesigned without using two middleware layers i.e. EI and PI and also without BPM.

Can you please suggest for new design with features in PI7.31 version to make the interface work with better performance.

Thanks,

Pavi
