Purge Task History manually

Hi,

I've read into console.log that there is some problems writing the global Task History

09/13/18-09:33:00:109 (9052) 0 Error al escribir en global de historial de tareas - Error (ERROR #5002: Error de cache: <DATABASE>%SaveData+20^%SYS.Task.History.1 ^SYS("Task","HistoryD",66179),c:\intersystems\healthshare\mgr\)

Hi guys,

I have a technical question. I have a Ens.BusinessOperation which contains a main method with parameters "In" As Ens.StreamContainer and Output "Out" As Ens.StringContainer. Return type is %Status.
Can this method just do "Quit $$$OK"?.
Currently this BO is used for see messages in Full Trace View.
It is a correct way to proceed?

Thank you

I am trying to find the presentation for the User Group Sessions that were given at Global Summit last week. In particular the Healthshare Provider Directory presentation, so I can share the ideas with others at my organization. Does anyone know where I can find those? I am not seeing them under the Global Summit tag.

Thanks

InterSystems IRIS offers various ways how to profile your code, in most cases it produces enough information to find the places where the most time is spent or where the most global sets. But sometimes it's difficult to understand the execution flow and how it ended at that point.

To solve this, I've decided to implement a way to build a report in a way, so, it's possible to dive by stack down

We have a UNIX VM with an InterSystems IRIS instance which we cloned for testing purposes, and we have found that $System (which is used for self-identification in email notifications) is still showing the hostname of the original VM, rather than the hostname of the cloned VM. This is coming from $System.INetInfo.LocalHostHame().

Does anyone know what you need to change on a UNIX clone in order for it to display the appropriate new host name in $System?

  • I have created a business service that uses an adaptor that I wrote by extending Ens.InboundAdapter (i.e. the ADAPTOR parameter is set to my custom adaptor ).
  • The OnTask() method of my adaptor polls our IRIS database to determine which records are ready to be sent out of our system to an external target system.
  • If the record is ready the OnTask() method creates an instance of the Business Service and then calls the OnProcess() method sending in the record as the input.

I am running csession on AIX. I have been using the command "csession cache -U%SYS". In the session the namespace shows as "%SYS>" as expected. I was simply doing queries to the best of my knowledge. At some point csession starting failing to reference the namespace instead showing /cachesys/mgr which is the main dir for the cache instance. I am not aware of doing anything that would cause this but more importantly, how do I correct it? I

I was hoping for some input on the best way to deploy code to site with the following criteria:

- No source code, only compiled code to be deployed.
- Classes and Routines are part of the application.
- Data and code reside in the same database.
- Deployments might be partial updates (i.e. cannot just send a complete CACHE.DAT).

At present the idea is just to export the .obj, any suggestions?

IRIS offers Durable %SYS Directory as a highly useful feature for working with containers.

Before inventing the wheel once more I'd like to know if a similar feature also exists for Caché / Ensemble.
Official documentation is quite silent about.
Though I have some names in mind that might know more about ( @Luca Ravazzolo ? @Dmitry Maslennikov ? @Eduard Lebedyuk ? )

I created a connector of type "Services" having for name of class "EnsLib.File.PassthroughService". In the parameters, the value "FileSpec " was "*" and the "FilePath " pointed to my directory " .... Documents "; whereas "TargetConfigNames" was empty.

Much to my surprise, as soon as I activated this connector, all the files were deleted.

These are not in the dushbin of Windows. -

Do you know a way to get back them? Are they in the system of the ESB?

I know that programs can undelete files. I have already used this type of programs.

Thank you in advance.

Hi,
I created a REST service that works well if called via VPN, for example the url http://192.168.10.60:57772/fm/status returns a JSON string as expected.
If I replace the ip 192.168.10.60 with the ip used for our public website nothing happens. If I remove the port :57772 the browser returns a 404 error page.
Do I have to use a different port or is this caused by the settings of our web server? (We are using Apache Web Server: Apache Cache_Server_Pages-Apache_Module/2016.1.0.656.0-1601.1554d)

Hi All

I'm looking for some field experiences, lessons learned, or actual deployed solutions to the problem of replicating non-CACHE.DAT data in a mirrored Cache environment.

Environment:

  • Operating System is IBM AIX
  • Hardware is IBM Power w/ virtualised storage
  • Cache 2017.1
  • 2x Production mirror members
  • 1x DR mirror member

Clone Class

Hi Guys,

How can I create a clone class so I can keep a copy of all records in that clone class?

Basically, I have a class where sometime records might be delete from it, so I would like to create clone class or merge the global content in another backup global so that records can be deleted from the original class but still have a copy of those delete records in my clone or backup global ?

Thanks
