Hi, would really appreciate your advice on how I can restart the mirror-monitor. I've followed the instructions and restarted the mirror monitor, and still the status seems to be down. Can you point me to some resource or steps that I can follow ?

I logged into %SYS terminal and restarted the mirror monitor and it says that it is running

This is embarrassing. I should know how to do this but I have forgotten.

I know the slowness of the 'Source' and 'Target' parameters in Message message viewer being slow to load is caused by the Bitmap indices of Ens.MessageHeader.

I know I need to run the 'bitmap index clean up' routine for Ens.MessageHeader to fixed the issue.

 What I forget is how to do this?

Hi, I'm still very much new at Ensemble DTL.  I am trying to set up an algorithm that requires loading fields from an OBX into an Array.  I don't think that I know how to iterate through the OBXs.  I know that there is a "for loop", that I will try to play with, but in the mean time, could someone tell me what is wrong with the following?

For example the code below works when I hard code the number 1 in OBXgrp(1)

I've created a scheduled task that dumps HL7 messages to flat files. It uses the OutputToLibraryStream() method of EnsLib.HL7.Message. I'd like to be able to run it on a mirror member host whether it's primary or backup.

When run against a database that's mounted read-only, it works fine. However, when I attempt to run it against a mirror backup database, I get the following error:

#5002: Cache error: <PROTECT>%LoadData+7^EnsLib.HL7.Message.1

Tracing that back to the source, I find:

I am trying to match on config items that have the same Vendor name in them for custom alerting.




Where Vendorname could be several systems that have multiple interfaces.

How can I find all config items (interface names) with the same Vendor name, without explicitly naming them?

Activity Monitor in Ensemble 2016.1

Has anyone tried the new Activity Volume Statistics and Monitoring  in Ensembel 2016.1? I would love to get some feedback.

If you haven't read about this, there is a dashboard that provides counts and response times for messages sent and received by each configuration item. Alternatively the underlying data is arranged in tables that should make it easy for you to use your favorite SQL reporting tools to generate reports for short term performance monitoring or longer term capacity planning.

We are trying to script a High Availability Shutdown/Start script in case we need to fail over to one of our other servers we can be back up within mins. Is there a way to configure the startup procedure to Automatically Stop/Start the JDBC server when shutting down or starting up cache? is there an auto setting we can change?

Code migration using VSCode

I am fairly new to using VSCode. I have used VSCode to create some files on our Test Server, now I need to move them to Production.

Looking through the VSCode extension documentation, maybe I missed it but how to I migrate code from one workspace to another. In Studio I was use to exporting the code into an XML and just being able to import it on the Production server version of Studio.

Handling Errors

I have a case where our EMR is sending data, but not all the values needed for the Ancillary are valued properly and causes that message to error/halt processing on the Ancillary system, not ideal but its what they do. I would expect them to still process the message except that 1 field, but they don't.

I want to add validation to make sure certain fields are valued correctly for the Vendor. 

So I add some statements to take those items that don't pass this validation out to a batch file with headers.

Hi All,

I am fairly new to Ensemble and I wanted to know I have inbound business service (EnsLib.File.PassthroughService) which is looking for pdf files once it finds a pdf file (within the business process) it needs to find the associated xml file which would be in the same directory. Once both of these files are found they need to be sent to the business operation and deleted from the source (EnsLib.File.PassthroughOperation).

It is with great pleasure that the CIUSSS de l'Estrie - CHUS is sharing the mocking framework it developed and presented at the InterSystems Summit 2017.  I will update this post with more detailed instructions in the next few weeks but I wanted to share the code and presentation quickly :
