#Mirroring

Basically the title, I couldn't find anything concrete in the documentation regarding this. The documentation states 'The user-defined ^ZMIRROR routine allows you to implement your own custom, configuration-specific logic and mechanisms for specific mirroring events, such as a failover member becoming primary.' I didn't see any more details on what exactly those mirroring events are besides a failover member becoming primary, which I wasn't sure if that included a DR async becoming primary.

Hi guys

I've added a new mirrored failover member to an existing one.

They are both Arbiter controlled.

When I do Add database to mirror on the primary I'm always getting an error. Missing Mirrored database.

I followed everything in the documentation and always get the same error.

I've copied the CACHE.dat file after umounting the database on both servers. then mounted them.

Could you help me out?

Kind Regards

I've setup ODBC connection so I can access Cache data within SQL Server.

I want to be able to write SQL queries for internal monitoring purposes, similar to what's possible with SQL Server. Specifically I want to be able to check mirroring status (i.e. check which is the current primary mirror member), check the status of any Ensemble productions (started/stopped), check the status of business hosts etc. I want to do all of this from SQL Server to go with our other system monitoring solutions.

Hi:
The task Mirror Monitor Launch Task recently failed and is placed in Suspend leave. Although it says USER it is not known as a task for us.

The code runs is HSSYS which is not our main system or namespace for production items.

The task name is HS.Util.Mirror.Task runs

If $system.Mirror.IsMember() Do ##class(HS.Util.MirrorMonitorAgent).StartAgent() and just says the description

/// This is the task definition that Launches the mirror monitor on any mirrored instance

Is possible config a docker-compose.yml to start arbiter-2019.4.0.383.0-docker.tar alone ?

What parameter you need ?

i can't find a simple sample

Hi

This morning I noticed that the ISCAgent.log for one of my high availabilty healthconnect servers has many entries that say:

"Mirror remote control command requested access to instance directory not found in registry."
Requested:d:\intersystems\healthconnect\

In addition, Messages.log has many of the following entries:

Has anyone noticed that when IRIS is forced down that the EnsLib.JavaGateway.Services do not properly shut down and release the ports? While we can write a shell script to kill the processes at the OS level, I was wondering if anyone experienced this issue.

We are working on our Mirroring setup/failover and had the team testing forcing the Primary down to make the Backup to become the Primary Server. When this happened and we failed back, IRIS could not restart the JavaGateway.Services because the ports were still in use.
