Hi Smythe,

This should be pretty straightforward! The docs cover a few simple use cases such as setting up Ens.Alert as a router to the email operation, or just having the email operation be Ens.Alert itself. Basically, the system knows to send interoperability alerts to whatever component is called Ens.Alert.

(These docs are for IRIS but the concept is the same for Ensemble)

To build on Yaron's answer, our documentation is quite helpful to understand the role of journaling and the WIJ. The individual chapters on each item respectively of course go into further detail, but here's a brief section describing the 2.

Differences Between Journaling and Write Image Journaling

I would also echo all of Mario's guidance - and to answer one of your specific questions above, the "warnvalue" is a configurable threshold for when a warning should be thrown, in your case I believe the default of 75% cpu usage. 

Anything else I would say I think has been covered by other commenters.

I might suggest you get the server running and verify that it is happy before trying to get in with Studio. It might be easiest to do it all from the cube - ie you can start iris from there. I mention that because I don't believe you're expected to call irisstart directly. You can call "iris start <instancename>" (distinction is using the iris command to call start).

If the cube fails to start IRIS it should throw an error (likely in the messages.log that the error will tell you to check).

Once you've started IRIS perhaps you can try accessing terminal and the management portal, then Studio. That could narrow down the communication error which may be generic.

I don't know if the picture is still uploading, but I can't see it. The fact you got prompted for USER implies to me that you had an existing connection to IRIS (likely with username/password autosaved) and that's why you immediately got to the namespace prompt. 

When you install the community edition you get Studio and the server locally - so I'm not sure what the downside of connecting to that server is, unless I'm missing something.

Ah I think I missed that part of your initial question. Studio isn't like other IDEs where it will save to a workspace on the filesystem, Studio writes to the IRIS database hence why it's asking you to connect to a (running) instance. That's why the icon is grey I assume, because you're not running IRIS. Since you said you installed IRIS and not just Studio I'm assuming you do have that IRIS instance available, but I don't know if Studio matches what you are looking for exactly - a barebones IDE that doesn't need to connect to anything.

Hi Ben,

Are you sure the install completed properly? Under the bin directory you can use CStudio.exe to launch Studio. If the tray "IR" icon doesn't appear, you can launch it with iristray.exe.

Hopefully you've figured this out by now but I'd suggest looking at the Filezilla logs to see if anythings stands out compared to the ssh log you get from IRIS.

My best guess is that the FTP server may not support specifically "key-pair" authentication or might require multiple forms of authentication and the other sftp methods you tried (Filezilla, sftp) may be succeeding with other auth methods. This is somewhat documented here:

You could reach out to the WRC with this.

As Alexander said, I would not recommend deleting journals from the OS. Worst case you make mirror syncing or transactions fail, or less bad but annoying you can orphan journals from the instance's record.

Journals are an important part of backup recovery as well (though a mirror covers some of that recovery role). How many days of journals are you keeping such that you fill your disk?

What kind of processes? Most user processes will need to be restarted on the other member. The mirror has some mechanisms to allow for, for example, productions to start automatically on failover, but for any given random process you probably need to handle that manually. You can use ZMIRROR.
