#Caché

I have some databases in my cache instance that were created from an online backup file (.cbk). I would like to see the information for these databases in the Databases and SQL sections of Management Portal, but they only appear in the Classes section. I can navigate to the files in my cache instance terminal and see the CACHE.DAT files, and a check in the terminal shows that they are mounted.
This is what I see in the terminal for each database when I check to see if the databases are mounted:
%SYS>set db="/path/for/mydatabase"
%SYS>w ##class(SYS.Database).%OpenId(db).Mounted

Good afternoon! 👋 We would be very grateful if you are kind enough to read and respond to our request 😊.

We need given an Authentication request issued towards our OAuth 2.0 authorization server; that in case of error, the responded message is customized.

Currently if we point from POSTMAN to:
https://[IP]:[Port]/oauth2/token?grant_type=client_credentials&scope=my/scope

Username: Erroneous
Password: Erroneous

We get:
{
    "error": "server_error",

}

We would need something like:

Hello,

I want to parse large JSON object and store data into persistent tables. Is there any other way besides pre-defining persistent classes including typing each property name? Maybe parse it and store properties into a global so that I know what properties need to be defined for each class...

Thanks in advance for your thoughts

I am exporting data from Cache using the SQL export wizard. This is on a docker image of Cache hosted on a Linux server.
I select my database, schema, and table, make sure that all columns are being exported, check other settings, and then finish the export.
All server settings look correct and permissions are rwe on the directory. I have tried various directories, including a system level directory. I tried creating the file before I do the export in case there was an issue with creating the files, and I also made sure the created files had rwe permisisons.
No matter what I do, it never creates

Hello,

As Intersystems Cache for Windows comes with a custom Apache version (2.4.52) and has some security risks, so not advised to be used for Production servers/environments. I want to install the new version of Apache (2.4.58) and replace it with the built-in version of it. Is there an easy and convenient way to perform this upgrade? My target is to completely replace the built-in version and replace it with a new version so that it passes the security scan.

Here is the link to the security risk mentioned by Intersystems:

Hi,

we need to take backup from alpha to dev environment on daily basis by automatic. Anyone please help?

When defining a server connection in Atelier we are required to enter a username and password because these are mandatory fields in the dialog. However, if the /api/atelier web application definition on that server has only the "Unauthenticated" checkbox set in the section titled "Allowed Authentication Methods", then our Atelier connection will succeed even if we supply an invalid username and/or password.

Hi Community!

Coding guidelines discussion. Consider you have For with one command in the cycle. Here are the options:

One

For i=1:1:1000 set ^Test(i)=""

Two

For i=1:1:1000 {
 set ^Test(i)=""
}

Same for the "If":

if a set b=a

or

if a {
 set b=a
}

Your choice? Or maybe even other options? 

Is there an ObjectScript analog of Find with Match Element Type option? I know there is an  ObjectScript analog of Find in Files, Studio.Project.FindInFiles and Studio.Project.FindInProject, but I failed to locate so far an analog of Edit/Find. I am specifically interested in Match Element Type option so I could search across selected files for globals. Somehow Studio.Project.FindInFiles does not offer this option natively.

If the system does not stop for 24 hours, old journal files will be deleted at 0:30 according to the "Journal file deletion settings".

A possible cause of journal files remaining that are older than the "Journal file deletion settings" is that there are transactions that remain open.

In that case, you will be able to delete the journal file by searching for processes executing transactions and finalizing the transactions.

The sample below checks for the existence of open transactions, and if they exist, outputs the target file name and journal record information.

Dear Fellow Cache Developers and Cache Experts,

The company I work for has a Cache Web Application that is built on the Cache ZEN framework.  The application has run very well for almost 2 decades across many versions of MS Internet Explorer ranging from IE5 all the way through IE11.   

However, when Microsoft finally phased out support for IE11, our company was forced to upgrade to MS Edge. While many of the old Cache ZEN features still work well, there are several, four specific scenarios listed below, that do not work as expected with MS Edge.

Hello, I am writing to you because I am receiving a strange error on our Integration server after restoring a Production copy.

On other occasions we had restored the Production copy on this server without problems (in fact it was done weekly)

After restoring the copy when entering the Studio this error appears:

I am inspecting our DB globals in order to reduce sizes of the worst offenders if possible. When I come to a large global, I am interested which of its nodes are the largest. Hence code below with unexpected different results. Any explanations why are results different?

partialGlobalsSize(dir,global)
S sub="",path="C:\Cachesys\mgr\"_dir_"\",searchGlobal="^"_global

W global,",",Size,! ; Got  725 here
S x=##Class(%GlobalEdit).GetGlobalSizeBySubscript(path,global,global,.Si

Wondering what version the Information.Schema schema was introduced, so that I can decide how to query the metadata for user defined tables. 

Thank you!

This error occurs when an instance of the class is already open at compile time.

There are two ways to deal with this issue:

1. Terminate the process or application that has the instance open
2. Compile options in the studio build menu: Check the compile flag “Compile classes in use” and compile.  

If you want to determine which process is using the class, try the sample routine below.

/// Test.mac
search(classname) public {
    Set pid=""
    Set pid=$order(^$Job(pid))
    While pid'="" {
        Do checkVars(pid,classname)
        Set pid=$Order(^$Job(pid))
    }

Hello Guys,

Our cache application uses REST web services and handles single API request perfectly with response (response status and related data). But sometimes user sends multiple requests to the same API simultaneously ( ie, without waiting for the first to respond ), where one request will succeed (not necessarily the first) and the others will fail. 
So, I need to handle the requests one by one after completing and sending the response for first request in the queue then process the next request and so on.

Is there any appropriate way of handling this problem?

I am trying to get data out of a cache backup. I am completely new to Intersystems Cache.
I got a docker image of Cache from this post: 
I want to get the data from my backup into this docker image. First, I need access to a gui and a cli, then I need some instructions or documentation for actually pulling in the backup data.
Thanks! This is all new, so pardon my lack of knowledge here. If I can provide any more information let me know.

Hi all,
Does anyone have experience with obtaining logs from Caché databases and parsing them now? Please leave me a message.

I ask because my project involves some hospitals that used Caché when creating databases over 10 years ago. Currently, we cannot replace the database, but we need to check and parse the database logs from the Caché.

Thanks.

Dear experts,

I'm trying exported a project from version '2012.5' to '2018.1.4' but is returning ERROR #7602.
Please, could you help me. How can I do it?
Below is steps that I did:

Thank you.

Hello, How are you doing?

I'm currently developing a proyect in wich I want to use %SYSTEM.Event to process queues. I realized that if a queue has events pending to be sent to the listeners, when I restart the cube the queue with all its events are deleted.

Is there a way to store the queue with their messages in a Global?

I've checked the documentation but I can't find any option for this prupose.

https://docs.intersystems.com/supplychainlatest/csp/documatic/%25CSP.Do…

Thank you!

in Management Portal on Freespace screen there are links to compact and truncate a database.

Can these tasks be done programmatically?  I have looked through documentation and dont see anything but I hope I just missed it.

Thanks,

David

If a relationship is set and there is a large number of n in a 1:n ratio, a large amount of memory may be consumed due to sequential processing of the relationship.

After referencing a many-sided object in a program and internally swizzling it, simply releasing the variable containing the OREF (deleting it, setting another value, etc.) will not free the many-sided object and the relationship object. This is the cause.

To free them completely from memory, you need to explicitly free them by freeing the OREF variable and executing the Relationship object's %UnSwizzleAt<%Libr

The Art of Mapping Globals to Classes (4 of 3)

The forth in the trilogy, anyone a Hitchhikers Guide to the Galaxy fan?

If you are looking to breathe new life into an old MUMPS application follow these steps to map your globals to classes and expose all that beautiful data to Objects and SQL.

Mapping Examples

Clearly if you have a fourth article in the trilogy you need to go for the money grab and write the fifth, so here it is!

Note:  Many years ago Dan Shusman told me that mapping globals is an art form.  There is no right or wrong way of doing it.  The way you interpret the data leads you to the type of mapping you do.  As always there is more than one way to get to a final answer.  As you look through my samples you will see there are some examples that map the same type of data in different ways.

At the end of this article there is a zip file with the collection of mapping

Now, let’s say you can’t access the terminal or simply you just rather execute it from a web interface. In this article, I will show you how to execute terminal commands from a simple web page.

For example, in the image below you see how we execute $zv on a webpage:

This is mostly possible due to the XECUTE command in Caché ObjectSCript. This command takes a string as a parameter and tries to execute it. This is the command used from the webpage, to execute what is being passed from the left navigation menu.

This article contains three snippets of code.

There is no need to recompile the routines after the version upgrade, but since the version update overwrites %SYS, user-created INT and OBJ format routines (*.INT,*.OBJ) in %SYS will be deleted. Therefore, you need to be careful. 

MAC, INT and OBJ routines with the following names are not deleted.

%Z*.INT, %z*.INT, Z*.INT,z*.INT
%Z*.OBJ, %z*.OBJ, Z*.OBJ,z*.OBJ

Please note that classes/CSPs need to be compiled after upgrading.

However, if you are upgrading to a maintenance release, no compilation is required. For details, please refer to the document below.

I got a problem to resolve, to sum it up I need to extract a function body from a JS file with cos.
I already got the JS code in a string and the function name but I'm kinda stuck as to how to get my function body, I already tried a few things (regEx, counter bracket) but there are comment and strings that block them from functioning. Is there a javascript parser or a good way to do it except by creating a javascript parser?

If multiple InterSystems products are installed on the same system, the latest version of the InterSystems ODBC driver among the installed products will remain registered in the driver manager.

You can change to any driver by changing the registry entry below.

 Please note that running RegFiles.bat does not change the ODBC driver.

The registry entry is as follows.

HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\InterSystems ODBC35 key Driver
