Hi ,
Can someone please help me on how to Avoid blocking in alwayson availability groups - synchronous-commit?
I did Set Up Alwayson Availability Groups- Synchronous commit, 1 readable secondary,Backups on primary
I have 2 Servers A(primary), B(Secondary) 1 mile away from primary, both are physical boxes with 16 CPU, 250+Memory and Good Disks-never had any performance problems....
We moved Server B secondary to a different location 15 miles away from primary and after 2-3 weeks we started having BLOCKING problems and making all applications break.. spoke to network and sys engg team and they say ALL good from their end n/w is up and healthy, and then once i changed the Synchronous mode to ASYNC mode everything works good no issues found since 1 month, now we are planning to change back to SYNC mode as we want automatic failover, I am Afraid that blocking might be causing again.. can someone please help me understand how to solve the blocking issue ..
as of now, we have 16 database, 500GB ins size total, Availability mode=Async commit, Failover =manual, connections in primary role=Allow all connections, Readable secondary=yes , session timeouts=10( both for primary and secondary)
Thanks,
