(We are in contact with IS support for this problem but I would like to ask Community too, perhaps somebody experienced this problem in the past)

Hello Community,

we need your help with Cache 2017.2 freezing on Linux machine.

Since we moved our primary production Cache from Windows to Linux in the begging of this year, we have experienced system freezing twice. Yesterday without any good reason Cache stopped to respond with the log shown below.

Simple problem:

  1. I leave a long-running command in terminal
  2. Switch to another task(s)
  3. Remember that I need to check on my command after a few hours

Is there any way to force terminal to the foreground after current command ends?

This is Windows with cterm/iristerm although Putty/Kitty solution would also be nice.

I am wondering the best way to disable a user account using this class in Cache (Security.Users).



Example User Account = jhipp

Currently is Enabled


I know that we can use the auto-generated EnabledGetStored method, for example:

%SYS> w ##class(Security.Users).EnabledGetStored("jhipp")

I am struggling to print out the actual property values of the Security.System class.



I was hoping to be able to print the Authentication Enabled properties of a system from the command line using the Get or GetProperties class method. Currently, however, I am only able to get a return 1 or Invalid Oref error.

Is it possible to write global output values to STDOUT, in a similar way to how csession can take routine intput, like below:


(In Cache Terminal)

%SYS>d ##class(%SYSTEM.License).ShowSummary()


License Server summary view of active key.


     Distributed license use:

Current License Units Used =        1

Maximum License Units Used =        1

License Units   Authorized =      200


     Local license use:

Current Connections =      1  Maximum Connections =      1

We have created an Ensemble production that receives HL7 information via TCP Adapters, but the requirement from the vendor is that we submit an ACK message with the MSH segment mist have a date and time populated with seconds.

We are utilising the standard class for the Service Adapter (EnsLib.HL7.Service.TCPService).

HL7 Version 2.5 no modifications currently.

The messages received via the service is correctly received in ddMMyyyyhhmmss but our ACK back is only ddMMyyyyhhmm.

Upgrade of custom application

Dear community,

we are a company located in central Germany working with Intersystems Caché since 2003 (Jesus, that's actually a long time in IT).

As we struggle to keep pace with outside development we still operate on Caché 2013.1 surprise

We are, of course, aware that we need to upgrade Caché and therefor plan an upgrade to 2017.2.

Currently, we are running 2014.1 on two different servers (OpenVMS, RHEL). The plan is to transition from OpenVMS to RHEL, but our Write Daemon is in a Troubled state on both servers.

On the OpenVMS server, we have a WIJ file that's 26G and can grow to 40G (size of database cache). Since it hasn't grown to 40G, we don't believe the size of the WIJ file to be the issue.

What else should we be looking at regarding the performance of the Write Daemon?

We will be transitioning from a server running HP OpenVMS to one running RHEL 7. The main question some of the team had was what would be the best method for moving the globals to the new system.

Also, I was wondering if any others have transitioned from OpenVMS to RHEL. If so, were there any kinks that we should be aware of prior to transition?

I am designing the software architecture for an Ensemble/Healthshare production to be deployed on Amazon AWS EC2 servers (2 mirrored m4.large - 4 vCPUs / 16 GiB RAM running RedHat Linux  3.10.0-327.el7.x86_64 and Healthshare for RHEL 64-bit 2016.2.1). It's a rather CPU-intensive production involving massive XSLT 2.0 transformations (massive both in terms of size and volume). I was wondering if anyone has experience configuring Ensemble productions on EC2 servers. My question or concern has to do with the following statement in the Ensemble documentation:

I am looking for a way to deploy production changes (code and/or production configs) via script or some other systematic way other than the Ensemble/Deploy page in the Management Portal. My goal is to store these configurations in Subversion, then have a piece that can pull the XML from source control and deploy it to a given server. Is there some kind of script that I can run on a given server to perform this deployment? If so, I can tie it up with Subversion using another tool that I have access to.

I have been asked to assist in the planning of the a new server for our database, which we will be changing operating systems from OpenVMS to Linux (RedHat distribution). However, its difficult to find material regarding what would be recommended, which is likely due to the database being proprietary.

In looking at the information provided below and hoping to decrease processing time, would anyone be able to recommend type of configuration we should have for the new Linux server? Please feel free to ask any clarifying questions.
