InterSystems Caché is a multi-model DBMS and application server. See more details here.

Hello,

For many routines we write, we utilize a global we name ^HITLIST($JOB,"routineName") as temporary storage as needed. For various reasons this gets junked up and we are at a point where we need to do some routine garbage collection.

The idea is to write a utility that looks at all the ^HITLIST($JOB) nodes, check if the job is currently running and if it isn't then we can issues the KILL command on ^HITLIST($JOB).

I am looking to run some analysis on existing software to quickly identify global variable references. Ideally you would feed in a "starting routine" and after going through all referenced routines you would end up with a finite set of global variables. So the primary purpose is to take say 10,000 lines of code and map out the referenced global structures without relying on a programmers eye. I found the post on Object Script equivalent to Studio "Find in Files" interesting but the downside is that output is too verbose and would require parsing to extract the global structures. How would you override writing to the terminal so that you could parse the data?

We have multiple databases running on a single server. I have duplicate interfaces on each database.

If we're doing testing in copy #1, the interfaces should be running in that copy. I want to block analysts who try to start the interfaces in copy #2.

So, I'm looking for something that would check the port and tell me the status: already in use or free.

My challenge is that this system needs to stay ISO/ANSI compliant.... so I can't use any of the newer tricks.
Is there any plain-old Cache' I could use for this task?

I am developing a viewer for Crystal Reports using the Crystal Reports for Visual Studio (CR13SP26). I have also installed the latest ODBC Drivers for Cache, but when I connect some reports to the Cache database using a connection string, I get an error that I failed to retrieve data from the database, and it reports the Database Vendor Code 30. Has anyone used Crystal Reports connecting via a connection string and received this error? If so, how did you correct it?

Thank you,

Brian Cromwell

Hello,

I am wondering the best way to disable a user account using this class in Cache (Security.Users).

https://cedocs.intersystems.com/latest/csp/documatic/%25CSP.Documatic.cls

Example User Account = jhipp

Currently is Enabled

I know that we can use the auto-generated EnabledGetStored method, for example:

%SYS> w ##class(Security.Users).EnabledGetStored("jhipp")

Hello.

I'm trying to export a XML stream containing some files that are supposed to have been written using UTF-8, but I'm facing some broken encoding issues.
You can see below that I'm indeed viewing a UTF-8 encoded and which is inside the CSP folder and encoded correctly (although displaying it on Studio would not display it correctly as the file is not using BOM and that's intentional).

A quick question regarding to SQL Query Plan:
Why these two requests have different plans, in particularly, why second request needs temp file? To me, temp file is a bad thing which should be avoided, right?

  1. select * from Test.Log where cdate = 1
  2. select * from Test.Log where cdate > 1

Plan for 1:

Read index map Test.Log.cdateIndex, using the given %SQLUPPER(cdate), and looping on ID.
For each row:
Read master map Test.Log.IDKEY, using the given idkey value.
Output the row.

Plan for 2:

Cache / Ensemble version 2016.2.2.853.0

I have a need to restrict ODBC access to certain users to prevent unwanted access to our cache database.

We have a limited number of legacy applications that use ODBC to connect to read data and are currently not in a position to have these amended any time soon so in the interim, I am hoping someone will be able to provide me with some assistance.

Any suggestions on where to start?

Information of Mirror servers

Hi

I'm using this query "Config.MapMirror.List" To get information of the list of servers that are in the mirror system.

I'd like to know how can I know which of the list is the primary and which is the failover or async member.

Is there a way to do it with this query? Is there another query to get this info?

Thanks a lot

Hello everybody,

My question would be, how is the recommended way to access Windows shares, also in view of future demads. Of course, I'm also happy about an explanation or code snippet of how the library, which is mentioned in the following , can be used under cache.

The classic jcifs library is easy to use, also with Cache, but as microsoft ceases support for smb1, we are currently looking for alternatives. jcifs-ng is such a library, which we took a closer look at. In java code a jcifs-ng file operation looks like this:

Hello,

When we need to create a utf-8 encoded XML file, we use the Charset property of %XML.Writer:

set writer=##class(%XML.Writer).%New()
set writer.Charset="UTF-8"

How can we create regular txt files with such encoding?

Our Cache Installations are 8 bit and not unicode.

Thanks,

I am trying to install Cache version 2018.1.0.184.0 on a Windows 10 System and i keep running into Permission errors during installation. I am getting

"Error 1406 Could not write value to key \SOFTWARE\Intersystems\\Classes\CLSID\{D11481CD-3B24-42E1-A20A-D179CDB6BEC5}\InstallCount"

I am signed in as an Administrator, i am running the installer as an administrator and i have edited permissions in the Registry to the referenced keys and i still can't get this to install. Has anyone run into this before and have some advice? I am pulling my hair out over here.

cache 2017.2.1 (Build 801_3)

when I look into the "sql statements" ( sql page of the management portal ) I have lots of old statements with a lot of them frozen. many of them are %sqlcq routines (I believe these are the SLQ's I run when testing/running random SQL queries in the sql page. )

I can clearly see where I can click on an individual query and untick an individual query to unfreeze it. or delete it. but thats a painful slow process. I can't see anywhere to delete/change multiple queries

%CSP.Rest custom headers

I would like a REST client to be able to send a custom header with the http request, for example "APPLICATION-ID".

This can be seen in the CSP gateway trace but I have tried using %request.GetCgiEnv("HTTP_APPLICATION-ID") in various formats and parts of the classes but cannot work out where I can get this. Documentation says this should work but is for normal CSP pages.

Any ideas?

Cache for Raspberry Pi?

Some may think it's a strange / daft idea, but just today the Raspberry Pi folks have announced that they've now sold more than 10 million of them..and counting. That's a huge potential marketplace, and a great platform for getting people to hear about Cache and try it out. Given its focus on the education sector, another great way of getting heard about.

I've writing a short classmethod that extracts an HL7 message from EnsLib.HL7.Message by ID and returns it as a stream. It's to be called as a stored procedure via ODBC (or ADO.NET) to fetch messages into an application.

I'm not using an SQL query in the classmethod itself, but it will be called as part of an SQL query via ODBC, but I can't figure out how to set a custom SQLCODE and error text from within the classmethod that propagates back to the external application. I thought %sqlcontext would be useful for this, but it doesn't appear to do anything. Here's the class:
