I'm in the process of setting up InterSystems IRIS for HealthShare with database mirroring, and I’d appreciate some guidance around how to handle an existing ODBC connection in this new setup.

Scenario:

We currently have a system running IRIS for HealthShare that external systems connect to via ODBC (using a standard connection string with hostname and port).
We're now configuring mirroring on this system — it will become one of the mirror members (Primary/Backup).
The external system using ODBC will not be part of the mirror, but it needs to continue accessing the IRIS instance seamlessly during failover.

Questions:

How should the existing ODBC connection be modified (if at all) to work properly with mirroring?
- Can ODBC be configured with a mirror-aware connection string?
- Or should we set up a Virtual IP (VIP) for the mirror and point the ODBC client to that and how would I make this mirror aware?
What are the best practices to ensure high availability for ODBC clients during mirror failover?
Are there specific considerations for HealthShare environments, especially with regard to externally connected systems (via ODBC) that are not mirror-aware?

Any official guidance, sample configurations, or insight from similar deployments would be greatly appreciated.

Thanks in advance!

Best regards,
Fraser

#InterSystems IRIS

Hi Guys,

How can I use this same objectscript principle in embedded python to get the value of each field in my loop?

s sql="SELECT ID, Name, Age FROM Sample.Person WHERE Age="_Myage

Set RS=##class(%ResultSet).%New()

Set Ret=RS.Prepare(sql)

Set Ret=RS.Execute()

While RS.Next()

{

Set name=RS.GetData(2)

}

it should be similar to this example which lists the whole row but how can I get the value of each field or if I can use GetData?

Thanks
