We are in the process moving in to hub & spoke architecture from the existing point-to-point architecture.
Currently all receiving channels are defined as RCVR. Given that RQSTR has got a hand-shaking ability with SENDR partner, I am thinking of replacing all RCVR channels with RQSTR channels. Which may give added comfort factor that if one NODE is rebooted the channels will be up and running straight way rather than waiting for SENDR retry period.
I know two differences between these two types - 1) RQSTR needs a fully qualified partner name 2) RQSTR sends a "request" for session initation. I am planning to keep the SENDR channels as it is. I am also aware of the fact that, changing the type means deleting the old one and creating new - means synchronising the channel sequence numbers etc.. This is all ready factored in.
We always had a dedicated receiver channel for each pair and not used any generic receiver channels. Also we use DNS names and not IP addresses so that in our Diaster Recovery we can swap the DNS entries to different boxes.
So given these, anybody out there still see any disadvantages of this idea.
Thanks for your input in advance.
Cheers
