[OpenSIPS-Users] Need some clarification in opensips cachedb_mongo db configutaion .

[Sasmita Panda]

Hi All  ,

I am using opensips 3.2 for fullsharing_cachedb clustering . Here I am
using mongo DB as the cache db .

I have 2 mongodb clusters , One  is primary (read/write) and second is
secondary (read replicas )cluster .

modparam("usrloc", "cachedb_url","mongodb://
docdb:cccl0g1c at primay-cluster.i3clogic.com:27017,
secondary-cluster.i3clogic.com:27017/opensipsDB.userlocation?replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false
")

When I am configuring 2 connectionstrings here , that means
1. Opensips will always honor the 1st one as primary and 2nd one as
secondary ?

2. If the 1st one will get down and 2nd one becomes primary , what will
happen to opensips ? Will that keep the 2nd one as primary automatically or
I have to switch the domain in the config ?

3. How does opensips decide which one is primary and which is secondary ?

Please help me out . I am stuck in the middle of something here .
