Mirror Member List

#Mirroring #InterSystems IRIS

Hi,

What's the best way to get list of members attached to a Mirror? 

In my scenario, in a Mirror set there are 5 members. 2 Failover, 2 DR Async and 1 R/W reporting.

On Primary, in the code I want to identify Backup member and then do my stuff.

And on Backup, in the code I want to identify DR Async and then do my stuff.

Basically the idea is to push file through code from Primary > Backup and then later files will be pushed from Backup > DR Async.

Regards

The class query MemberStatusList in SYS.Mirror (found in the %SYS namespace) will give you a list of mirror members and some useful status information:

%SYS>d ##class(%ResultSet).RunQuery("SYS.Mirror","MemberStatusList")
