Which DB is the one to store persistent messages in Qpid C++?

[Harvey Li]

Hi guys,
I knew we used berkeley DB for persistence in Qpid java. Which is the one in 
C++ version?
 
BTW: In Active-Active cluster mode shall we share folder for persistent 
messages? Or we must share a rdb? Actually I didn't get details on how to build 
a A-A cluster. Where can I find it? I will appreciate if someone points it out. 
 
Thanks.
