Hello,

I'm currently exploring alternatives to CSP/services and ODBC/Sql Maps for access to Caché. I'm not seeing a library which would interest me, so am considering creating one myself.

Does 'CacheConnection' in C# use RPC of some sort, or a defined protocol to communicate with Caché, or does it do so over telnet with scripted commands? I would assume the former. If so, is this a publicly documented protocol that can be implemented by library developers?

Any guidance in this area would be appreciated.

Conflict Resolution Wizard

Hi

When trying to sync a class to the server where the server class has been updated by another user, I, as expected, get the Conflict Resolution Wizard.

I can then use the wizard to copy code from the server side to my local copy using the arrows also as expected.

But when I have integrated the remote code into what I think is my local copy how do I save it so that it gets integrated into my local copy and synchronised to the server.

hi-

Can someone give me an example of how to JOB a class method that requires an array of values to be passed to it by reference.

This is what I tried, but am getting compile errors because of the .params

job ##class(%SYSTEM.OBJ.FM2Class).All(.params)::5

Any thoughts on how to accomplish this, the simplest way. I would like to avoid writing all of this to some global and having to write some wrapper to pick it up and then call the class method, which I certainly could do. but is this the only way to do it?

Hy.

I set up cache in container, which is working fine. But when accessing managment portal the default user was alway Unknown user and no username or password were required. So i disabled the Unknow user in the Security section, but now i keep getting an error access denid.

I was looking at the OrefToArray^%occRun in the %CSP.ErrorLog page in version 2016. However, we're on version 2014, and that method does not seem to exist yet. I would love a good way to swizzle out the info in the %request, %session, %response objects for the error log for my own error page, in version 2014. I don't want to have to go through and get all the properties manually, but I will if I must. Any other good way already written?

Thanks,

Laura

In addition to its general security, Caché offers SQL security with a granularity of a single row. This is called row-level security. With row-level security, each row holds a list of authorized viewers, which can be either users or roles. By default access is determined at object modification Some time ago I became interested in determining row-level security at runtime. Here's how to implement it.

Caché service does not start

Help, after a day of coding, I wanted to backup my files. I found out that alle of my 3 instances of caché refuse to start.

the error says: cstart-exe-fout (112 Service for Caché instance did not start).

Is there a way to solve this? (off course the management portal does not work either.)

I think there has been a power interruption as the battery from my laptop does not work, and the power went off before

shutdown.

Thanks in advance!

I am looking for experience of people running Veeam with Caché databases.

Tips/Tricks/General questions like; what Veeam features are you using, what your backup cycle looks like, where does your data end up, what recovery/integrity checks you do, what sort of compression/dedupe you get.

Also what questions _you_ have and what problems you might be trying to solve.

Hello experts,

I’m working on an "Sort After" (]]) bug that I traced back to some weird behavior in ObjectScript. Perhaps someone can enlighten me…

The problem is as follows:

Let’s say we have:

Set A = “1.0”
Set B = “2.2”

If you execute the command ‘Sort After’ (]]), you get the following:

W A]]B
​1

…Which is wrong, A does NOT sort after B. The output should be 0.

If you set A and B to numeric values, it correctly outputs false (0):

set A = 1.0
set B = 2.2
​W A]]B

0

Hi All,

I use SQL function JSON_OBJECT to get data as a JSON object.

However, sometimes I get error with function JSON_OBJECT when values contain [, ], { or }.

Error:

[SQLCODE: <-400>:<Fatal error occurred>]

Unexpected error occurred in JSON_OBJECT() function execution of <JSON_OBJECT>.%FromJSON().Parsing error

For example,

Query: SELECT JSON_OBJECT('idSQL':id, 'content':content) FROM DocBook.block

padding string in BPL

Hi folks, I'm trying to pad my patient MRN to 10 characters before I do a SQL lookup in my BPL. I've tried various approaches, and have not been successful.

When I add a "code" statement with the following code, I get an error as below.

Today %SYS.Namespace.ListAll started to report one namespace, for example USER, two times: once as "USER" and once as USER's database "^^c:\databases\user".

Details: my Cache instance has 50+ local namespaces. Today I have "touched" 3 of them (imported new classes), and now ListAll reports each of these 3 twice. Looks like ListAll is the only one who sees those strange duplicates, in all other places (Portal, Studio) only USER is shown.

Can someone explain what is happening?

Grand Total

How can I create a calculated field that will give me the grand total of a column? For instance, if I have a row that has 200, 300, 500, 600, how do I get the Grand Total?

I have already used the wrench under Column Options as % of Total so, I can't use that option.

Dear InterSystems Community! Do you control your Caché or Caché controls you?

Recently, I decided to start the project about control of Caché instance. The control is based on communication with chat bot.

For example, below text message shows current statistics of the certain Cache instance.

/stat <cache-instance>

Hi all,

We faced a problem where we would like to map a $lb object to its corresponding data model structure in order to later on export it as JSON.

So imagin that we have something like this that actually maps to a persistent table with its structure. 

$lb("",,,,,"",,,"BOOLEAN","0",2,2,"1",,"bla",$lb(,,"bla","20050502123400"),"",1,"bla",,0)

Is there a way to transform this $lb (without the need of openig the object itself) to a JSON object with the proper table fields as properties?

Many thanks

Atelier BPL editor

Is there a way to graphically edit BPL processes, or do we still need to use Studio for doing that?

Looking at the documentation, it appear there should be an Atelier BPL editor option available under Open With, but all I have is Atelier Class, HTML, INT, and MAC editors.

There is a BPL editor in the list, but it throws a "Bad editor input" error when trying to open the class file.
