TCP adaptor + SSH Tunnel

Greetings.

We have one vendor who requires us to send data using TCP

through an SSH port forwarding tunnel that is set up in advance.

UNIX scripts maintain this, and the Ensemble interface uses a TCP Adapter.

I was thinking that Ensemble could maintain the SSH tunnel,

which would improve our detecting of issues.

Has anyone done something like this?

I see that the class %Net.SSH.Session has a method ForwardPort,

but it doesn't stand up the tunnel by itself. Instead, it appears

I installed the Cache client along with Atelier on my mac.

My question is:

How do I access the Management Portal on a mac?

My Atelier stand-alone app allows me to use the Cache instance, but how do I get to the Management Portal to set up security and create new namespaces, etc.?

Also, where to I check to see when Cache is actually running?

Thanks.

Hello; We are managing several Ensemble instances on several servers. One server has 4 instances, and two other servers have one instance each (those are production servers). We encrypt all instances using the Caché encryption in the management portal.

Currently we are using two different encryption keys: 1 key on the server with 4 instances, which is used for all 4 instances, and a second key on single-instance server. ( I'm installing the newest production server now.)

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?

Hi guys,

I am trying to run a command line code using $zf(-1) in cache terminal. it is returning access denied error.

I have tried to run the code in cmd itself it is also throwing Access denied error. But if opened cmd as administrator and run the same code it is working perfectly. I am using windows system.

Hence i need to know how can i run the cmd line code as administrator using our terminal or studio. Please help me out.

Thanks,

Mani

I'm trying to write an installer manifest that can create a namespace, resources (%DB_namespace) and a role (with the resource, above), based on the namespace. So you could pass in "ABC", or "XYZ", and it would create the %DB_ABC resource and the ABC role with %DB_ABC:RW permissions; or it will create the %DB_XYZ resource and the XYZ role with %DB_XYZ:RW permissions, accordingly.

Recently, we scheduled two tasks (1008 and 1009) within Task Manager. Task ID 1008 is set to run after Purge Tasks (%SYS-ID:3), and Task 1009 is set to run at 7:00:00 each day.

In attempt to provide as much detail as possible, each of the tasks are as follows:

  • Task 1008

    WHILE (($p($h,",",2) < $ZTH("10:00 PM")) && ($P($g(^Task.1008(+$h,$j)),"^",1) = +$h)) { J ^ROUTINE, ^ROUTINE2 D SUB^ROUTINE3 H 5 }

Terminal license expire message

If you are facing out the license expire warning message on your terminal ("*** Warning: This Cache license will expire in 3 days ***") and you do not want that message to be displayed, you can disable/enable that by rinning the following commands:

Do ExpirationMessageOff^%SYS.LICENSE - Disable

Do ExpirationMessageOn^%SYS.LICENSE - Enable

I have a Powershell script to backup up a Cache database. The script runs through and backs up the database with the normal 4 iterations. The script successfully produces the backup file and an associated log file. However, after completion of the backup there is what appears to be a permission error. I have not been able to find any information that would help me determine if this message impacts the integrity of the back up. From the end of the output of the backup:

Currently, we are utilizing batch jobs at the OS level to kick off routines that watch for files. We are trying to convert these processes to be performed by the Task Manager.

The routines have while loops and perform while loops so long as the time parameters are being met.

What's the best way to ensure Task Manager kicks them off after the completion of the shutdown/backup/start process is performed, which we do nightly? I want to ensure that it starts it regardless of the time that we've set.

System Monitor is a flexible and highly configurable tool supplied with Caché (Ensemble, HealthShare), which collects the essential metrics of the operating system and Caché itself. System Monitor also notifies administrators about issues with Caché and the operating system, when one or several parameters reach the admin-defined thresholds.

Hi!

I am not system admin. But it used to be very simple to install CSP Gateway on an apache system on Linux with Apache installed. I used to run the CSP Gateway installation program and after it was done, all I had to do was fine tune some configurations on CSP Gateway portal on http://<ip>/csp/bin/Systems/Module.cxw and I was up and running.

This post will show you an approach to size shared memory requirements for database applications running on InterSystems data platforms including global and routine buffers, gmheap, and locksize as well as some performance tips you should consider when configuring servers and when virtualizing Caché applications. As ever when I talk about Caché I mean all the data platform (Ensemble, HealthShare, iKnow and Caché).

Hyper-Converged Infrastructure (HCI) solutions have been gaining traction for the last few years with the number of deployments now increasing rapidly. IT decision makers are considering HCI when scoping new deployments or hardware refreshes especially for applications already virtualised on VMware. Reasons for choosing HCI include; dealing with a single vendor, validated interoperability between all hardware and software components, high performance especially IO, simple scalability by addition of hosts, simplified deployment and simplified management.

EmergencyId startup

Hello, I am writing to request assistance on an issue I appear to be having when accessing Ensemble.

When starting Ensemble through the command line window using ccontrol start ENSEMBLE /Em... I get an error and Ensemble does not start. Below is the error message I am getting when checking the logs:
