Good day!
Is there an opportunity to debug the ISCAgent behaviour (in Linux)? ISCAgent uses /etc/iscagent/iscagent.conf as configuration file, but in docs I've found a description only for two parameters (port number and interface - http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=...). Other parameters I can see by running /usr/local/etc/cachesys/ISCAgentCtrl status:
I've been trying for a while to come up with a set of tools to monitor the health of a mirror set and email a report nightly on the status of the mirror, or flag issues in real time. Making sure that all the databases are caught up, that all the mirror members are online.
I have a DR Mirror with a WIJ that is 5 times as large as the Primary Failover member. My Read-Write Reporting mirror WIJs are the same size as the Primary. I don't know why the DR WIJ i so large and would like to shrink it to the same size as the others. Any suggestions are welcome. Thanks!
I turned off server "SOROSERVER1" and tried failover to server "SOROSERVER2", but is returning a lot of errors in log (cconsole). Below are messages saved in cconsole log.
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.
We currently have CSP application that runs under 2 servers(usually primary), and every month the server reboots for patching SERVER1(primary) in the morning and SERVER2(backup) at night.
Whenever the SERVER1 reboots SERVER2 behaves as primary and when SERVER1 comes back up it will act as backup server.
First Patching:
So, when SERVER1 is down, I need to start httpd service for SERVER2 and stop httpd service for SERVER1 (which is now backup server).
I've created a scheduled task that dumps HL7 messages to flat files. It uses the OutputToLibraryStream() method of EnsLib.HL7.Message. I'd like to be able to run it on a mirror member host whether it's primary or backup.
When run against a database that's mounted read-only, it works fine. However, when I attempt to run it against a mirror backup database, I get the following error:
Initially when setting up a cache instance one creates or imports the user/ resources roles etc .
After the Mirror has been activated you can add users, resources etc. But when trying to add new SQL Table privileges to a namespace where the databases are mirrored it seems that you are not able to , Getting error:
I am receiving Mirroring updates to an IRIS for Health async reporting server and need to pause the mirroring journal processing to periodically quiesce the database to rebuild cubes and custom staging tables.
What API or web service can I use to quiesce the reporting server and then later initiate catch up?
Looking through Mirroring routines sources, I've noticed these terms, while even the latest documentation keeps silence on them. I'm just curious what are they, and how to configure / to use them?
Is there a way to force a failover from the primary mirror member to the backup member without forcing down the primary (which happens with ##class(SYS.Mirror).BecomePrimary())? What I'm trying to simulate is a network isolated condition on the primary.
This might be a dumb question but I didn't see anything about it in the Mirroring documentation. Are processes that are currently running when the primary fails over to the secondary automatically switched over and continue processing? Or are they terminated and would need to be restarted on the secondary?
Is it possible to make the cache terminal available over a mirrored vip address for a healthshare mirrored environment? So that connecting to a terminal for a mirrored environment will always connect to the Live Node?
I'm looking to write a Powershell script to run against the system and need to connect to the Live Node in a mirrored setup. Is this possible or am I going to have to log onto each node to establish which is Live. Or does this even matter?
I want to know if there is a way to manually change Primary to secondary and vice versa?
I need this becasue we backup the two VMs (primary and secondary) and my idea is to make a script to when the primary VM is going to backup with Veeam change to "backup" on the mirror.
I have Ensemble/Healthshare running in a production environment which is setup with a mirror failover and an arbiter sitting between them.
In the event of a failover we have a number of connections that need stopping/monitoring and starting in a certain order.
Is there a programmatic way we can detect the failover and stop certain services and operations immediately and then start them up again in the required order, checking their connection state before starting the next connection.
Hi, we have mirrored databases, now we have three nodes. Primary, backup, async. They are sync by journals and with some TB each node (expensive storage).
I would like to have a scenario where the two nodes (Primary and backup) have the same amount of messages (purge task of x days) , both as failover, but the asynchronous node should have more messaging, as much as the storage allows us. We want to use this node so provider can give support(search old messages), but not have databases in production that are so large that they are hardly consulted.
I have a pair of servers configured as a mirror, each server sits in a separate data centre.
I have noticed that occasionally, the primary will report that the backup is disconnected in the Mirror Monitor, and I believe this to be due to connection conditions between the two data centres.
I work on deploying IRIS inside Docker container. I really like %Installer class can automate many steps. I want to establish an ECP connection to a mirror database and then define a remote database on the application server. I have already seen we can create local database and namespace in %Installer. What code is needed to establish ECP connection?
