Make sure your hardware is healthy.

Nicki, I would start with your account manager and have a chat about how best to migrate.  Since Ensemble and IRIS for Health are different products, the specific versions involved matter a great deal.  A sales engineer on your account team probably has seen migrations such as the one you propose.

As for differences between IRIS and Ensemble, check the Migration Guide which you can download from the WRC.  There's a lot there, but it includes the result of a lot of testing and migration experience.

And of course, if you are finding something that doesn't work as it should, reach out to the WRC.

Rob, if your organization has support from InterSystems, then there is usually one of your colleagues who manages the people who have WRC credentials.  They should be able either to download the driver you need or to request credentials for you.  If you think you should have credentials, or you forgot username/password, send a request to support@intersystems.com asking for credentials (use your organization's email).

Hi Gary,

If you have a default Docker installation, there is no daemon.json there until you create one to alter the default behavior of Docker.  This external post discusses it in more detail.

Post more about what you are trying to achieve if this doesn't answer your question, or contact the WRC.

Earlier ODBC driver versions should be compatible with Caché 2018.1, but we recommend updating clients to the latest driver for your Caché version.  There aren't any 2021.x ODBC drivers for Caché on the WRC download page.  If you have one and you want to be sure you have a good driver, reach out to the WRC so we can understand your specific situation.

Rob, the ODBC drivers for IRIS are not compatible with Caché and Ensemble.

Hi Hoi, nice to see you in the community. You piqued my curiosity about FASP and I found this white paper about it: https://www.ibm.com/downloads/cas/7D3KBL9Z.

I don't see any support for this in our class reference.  If you are looking for support for this in InterSystems IRIS, I would start with your InterSystems account team to explore what you need and what alternatives might serve.

Scott, the WRC may be able to help if you haven't resolved this.  The details will matter a lot (what VM/OS version/Docker version/etc.).

I have seen troubles on Ubuntu VMs under WSL2 using SysV init rather than systemd, which causes trouble with software that expects systemd.

Erik Hemdal · Nov 3, 2021 go to post

Thiago, I would try downloading the latest image again.  The embedded license expired a short time ago and the image was refreshed.  If you continue to have trouble, reach out to the WRC for help.

Kevin, manually allocating space for a database file allows you to (as Alexander mentioned) avoid expansions on-the-fly.  In some applications that extra overhead isn't desirable when the system is running.  Pre-expanding the database also commonly results in a contiguous file on disk, which can improve performance of storage and backup operations.  There can be other reasons, too, why limiting the size of a database would be desirable.

Robert, +1 for Kepner-Tregoe ATS.  That was one of the first seminars I took as a new engineer, and it still ranks as some of the most-useful training I ever had.

Erik Hemdal · Sep 22, 2021 go to post

It should work.  Windows privileges need to be correct, and in recent Windows versions, it is not as simple as running as an Administrator.  If you have specified a user to run the IRIS instance, rather than the Local System account, run the irisinstall setserviceusername command (details are in the documentation) to set privileges correctly.

https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cl…

The InterSystems WRC can also help if you are truly stuck.

You can also use a reporting async or perhaps an ECP application server, depending on what analysis you are doing.

If the advice you have so far doesn't help you make progress, you might consider a chat with your account team.  They usually have experiences to share about cases like this.

Erik Hemdal · Jun 30, 2021 go to post

There isn't a Web terminal built into the product but some customers have used the application from OpenExchange on their own.  You can access an IRIS terminal via 'docker exec'.  The best way depends on your specific conditions and requirements.

Post more details if you have more questions.

Gulshan, the path you take depends on how much money you want to spend and how you prefer to learn.  You have a lot of choices.  I'll add this one to the list of good options the others have posted:

https://wiki.python.org/moin/BeginnersGuide

It's an important language to learn for a lot of fields.  Good luck and post back here with what you chose.  That will probably help a lot of others.

Thank you, Michael, a picture will help a lot.  It sounds like Rose is some kind of server clustering solution that allows two servers to share a disk.

@wenjie zhao, if you are using Caché 2016.1 today, I would suggest that you discuss this with your account manager, who is probably most familiar with your system.  Your account manager can bring in technical resources if necessary to help you.

The InterSystems IRIS data platform is the engine in InterSystems' current product set.  IRIS for Health adds capabilities related to healthcare applications and DeepSee (part of the older Caché database engine) allows you to embed business intelligence capability into your applications.

For new development, or if you are just getting started, I would look to InterSystem IRIS and the products built on it, unless you know you have a specific need for Caché.

Rico, did you resolve this problem?  InterSystems Support can help you with startup issues if you haven't fixed the problem.  If you have fixed it, let us know what you did to cure it.

James,

The system-provided audit events are documented here:

https://docs.intersystems.com/iris20201/csp/docbook/Doc.View.cls?KEY=GCAS_audit#GCAS_audit_sys_events

Check to see if these events will give you what you need:

  • %System/%DirectMode/DirectMode audits commands run at the IRIS terminal.
  • The events under %System/%SQL audit SQL commands.
  • %System/%System/OSCommand audits $ZF calls.

There are many others that track logins and system changes.

Yossi, thanks for writing back.  I'm really happy that you got an answer about this and that you posted back. 

Erik

Erik Hemdal · Apr 21, 2021 go to post

Commonly, help with questions like this starts with your account manager or your sales engineer.  But @Timothy Leavitt  has a good suggestion too:  you can contact Support by phone or email and a support advisor will help you get what you need.

Erik

Erik Hemdal · Mar 3, 2021 go to post

Yossi, I'm not familiar with CommVault and the VMTools (although the VMs I use here do have them installed).  I have seen a variety of troubles cured by making sure the VMTools are up-to-date.  VMWare or CommVault support might be best for that. 

As for Caché, make sure that EnableVSSBackup is set to 1 (true) in your CPF and that SYS.VSSWriter.1 is running (check the process list in the Portal).  The VSS writer for Caché can be started only by an administrator on Windows.

I don't have much more advice, if this doesn't get you working, I would contact WRC directly.

Erik Hemdal · Mar 3, 2021 go to post

Yossi, I have worked with customers who use CommVault and it is mentioned in some of our reference architectures as an example of a backup solution.  We can try to help you here if we know more about your problem, or you might consider contacting the WRC for direct help.

Matthew, in which log or utility are you seeing the "Dead" status?  That can offer a pointer about how you could detect the dead jobs.

Do you know the cause of the dead jobs and what is the impact?  The WRC can help sort that with you.

Erik Hemdal · Feb 19, 2021 go to post

Others, including me, were noting this message in the log you posted

02/08/21-09:17:54:464 (7016) 3 [Utility.Event] Error: Invalid Community Edition license, may have exceeded core limit. - Shutting down the system : $zu(56,2)= 0

which is definitely unhappy about the core count.  Rich has good advice if you are able to start the instance but are unable to run only some jobs.   If you have a full license and you are still unable to sort this out, reach out to the WRC and an advisor can assist.

Please let us know if you have progress, several of us are interested in your success.

Priya, there is a limit of eight CPU cores for the Community Edition of InterSystems IRIS products.  If you are using a Docker image, add

--cpuset-cpus=0-7
to your 'docker run' command.  On a native server, or VM, you need to limit the cores available using the methods for that server (or use one with fewer cores).

https://docs.intersystems.com/irislatest/csp/docbook/Doc.View.cls?KEY=A…

Let us know if this resolves your trouble, and all best in migrating to IRIS.

Paul, if you are working with one of our partners, then they are your best source for information about how the application is supported.  The versions supported by partners can be different from those supported by InterSystems.
