We have an web application accessed using https, that uses CSP technology with frames.

The initial 'login' is via a single CSP page, which then redirects to another CSP page which creates the frames (4 in all) and loads a CSP page in each of those. For the most part the frames load without error, but sometimes when logging in and sometimes while using the system ' 5916 Illegal CSP Request ' errors occur.

I say 'login' in inverted commas as a Cache login is not performed just an application login, I don't know if that's relevant so thought I'd mention it.

how to release row lock?

I have restored one database from backup, but when I query from some of tables, prompt error :

this error remain after restart Caché service

I can skip this error with %nolock in select query.

My question is:

1. why there were locks after restart service?

2. Can I release/rollback these locks by sql so I can query without %nolock?

Force inner select to be executed

I have a query that I am attempting to run, but inner query is being rolled up into the overall query - per the optimizer (and jobexam observation). While I know that if the inner query runs first, I will eliminate a number of records (making the result set smaller, and return quicker).

Just an example of what I am attempting to do:

Hello All,

I am looking to send out an email based on a patient's discharge where PID13-4 contains their email. We are currently using something similar with an Email.OutboundAdapter. However, in our current scenario we have a hard coded email in place as the recipient (as this is for order notification to a pager). In the scenario in question, I would need PID13-4 to populate as the recipient of the email. Does anyone have an example of something similar, or a suggestion on where to start?

Thanks!

You walk into a room, step on a tile and hear a loud click...

Traps !

The challenge is about avoiding traps.

You can recognise if a tile is a trap by following scheme :

Thanks a lot, that we finally got the new version of Atelier, where most of the errors were fixed.

But I've found some have not fixed yet.

    set destination = $listget(waypoints,*)
    set $list(waypoints,*,*)=""

In this code, Atelier does know about asterisk as a second argument to $listget function.
And in this case, even shows next lines as an error.

I'm trying to write a method to Export SQL Privileges from an instance by namespace, user, or roles. I've found two classes that might work:

  • ##class(Security.Users).Export
  • ##class(Security.SQLPrivileges).Export

One (Security.Users) exports an XML file and the other (Security.SQLPrivileges) exports an SQL file.

To simplify the upgrade processes and to keep up with industry standards, we decided to make Atelier only available as an Eclipse plugin. Those of you who are currently using a standalone Atelier client will not be able to upgrade to a later version.

Please go to the Atelier Download page or see the sections below for the detailed instructions about installing Eclipse and the Atelier plugin. Feel free to reach out to support or leave a comment down below if you have any questions.

I'm looking for information, suggestions, video (courses) on make a lot more use of the documatic system already built into Cache,

Probably talked of before within this forum, but after an hour or two of searching, can't find the articles that I mmay have seen before.

I want to do a lot more documenting of my installation, we use and actively comment classes and methods, but I want to take it further by actually documenting the "why" and high level "how" my system works. Documatic seems a good place to put that knowledge.

Can anyone suggest suitable Cache ObjectScript syntax for open/use/read statements on a simple ms-dos text file.
I've tried various examples seen on the web but they appear to be implementation specific.
I used MSM MUMPS many years ago but am now retired & would like to write a few simple routines for my own amusement & mental challenge.
I am using the free Version of Cache (V 2017.1) on my Windows 10 PC. The installation file was CachePCkit_x64.exe
My apologies for this query being very basic.

Hello Caché Guru,

I'm new to Cache system. I'm trying to do something like saving meta data in Relational DB:

I could use "management portal" -> System Explorer->SQL to view individual table's catalog details or print out the column definition. However I need to gather those information for several hundreds of tables in the DB. Is there a way to do it using command line in kind of batching mode?

Any hint and tip is very much appreciated!

Thanks in advance!

Victor

Hi everyone,

I started working on Ensemble this year so maybe I am not implementing the right way. I'm trying to connect a Welch Allyn monitor to TrakCare. The workflow is the following:

- User scans patient number with the monitor.

- The monitor sends a QBP_Q22 message to request patient information

- Ensemble (or TrakCare) sends back a synchronous RSP_K22 containing the patient data (name, dob, sex)

- The user checks the patient's information displayed on the monitor, takes vital signs and sends them to TrakCare (via Ensemble)

Hello,

I'm looking for a way to programmatic ally add the parameter 'VALIDIFNULL' to classes that extent %SerialObject.

This to hopefully resolve the validation errors I'm getting on webservice request messages, where certain properties are not required, but lower down the tree some properties are.

I have too many classes to do this manually and with the next SOAP wizard run I probably loose the added parameter.

Some help would be very much appreciated.

Regards, Michel
