Is there any easy way to create a WebSocket to Telnet proxy within the Cache environment?

I would like to use a html5 telnet emulator to connect to cache, but need to create a proxy,

Is this a simple task?

%XML.Reader.OpenFile fails with SAX XML Parser-Error: <STORE> on importing large (1.5 GB) xml file. Any workaround for it?

My goal is one-time import of the file using classes generated by its XML schema.

I want to generate one of the following xml data, but after I generate only de="", after I need to generate is de="DEX71.41.009.01"

//// result:
<OPTREGISTER>
      <THBZ de="DEX71.41.007.01" display=""></THBZ>
      <GHFS de="DEX71.41.008.01" display=""></GHFS>

Hello glabal masters,

I am trying to develop WAS using Cache and Spring Framework.

Hi everybody,

 I need to load data from excel to a class in cache, but this class has foreign key and property like AS ..... (other class). This class represent an item product that belongs to a line, the line blelongs a group and the group belongs a Category.

Hi,
I created a REST service that works well if called via VPN,  for example the url http://192.168.10.60:57772/fm/status returns a JSON string as expected.
If I replace the ip 192.168.10.60 with the ip used for our public website nothing happens. If I remove the port :57772 the browser returns a 404 error page.
Do I have to use a different port or is this caused by the settings of our web server? (We are using Apache Web Server: Apache Cache_Server_Pages-Apache_Module/2016.1.0.656.0-1601.1554d)  

Thanks in advance!

Hello; we have users on the system with cache logins.  They have access to a specific namespace, and no access to %SYS of course.  I'd like to give each user the ability to change his own password from within our application, using Security.User.PasswordExternal.  This only exists in the %SYS namespace, and the average user can't get to it.  

Should I give the users access to this column in this table (column Password, table Security.Users)?  What about access to the namespace?  Is this possible? Has anyone done this before?

Thanks,

Laura

Hi Guys,

I'm upgrading Cache 2008 to 2014, and for two clients so far all good, but with this third one and while trying to mount the main database that includes the data, I'm getting error #36 "database is not mountable"!?

but cache instances the old 2008 and the new 2014 at installed the same way (8 bit) and Cache.dat is (archive) NOT read only so I don't know what could be the problem?

Thanks

We upgraded from 2017.1 to 2017.2 today and noticed that when shutting down we must do it as an administrator.  Attempting to shut down as a non-admin result in a failure to shut down message.  We are curious if there was an issue with our upgrade or if there is a change that requires an administrator to shut down Cache in 2017.2.

edit:

Operating System is Windows Server 2012 R2.  We run Cache in a cluster using Windows Failover Cluster where we swing the drive from one machine to another when failing.  

Interesting to see this latest ranking come to my attention:

Look what's ranked 16th.  Shame a decision was made to deprecate it 

I have a very large logistics software running Chache.

I need to build an external application ( Web & Mobile)  . I was thinking of using Angular. Does anyone have experience with this infrastructure ? What would be the best way to extract the data ?

We have this challenge at our site. When we first designed it many years ago, we decided that the best way to store files was with a unique identifier, which matched one of the fields in the corresponding record. For example, if the unique identifier was a nine-digit field (such as a SSN), we'd save a file as nnnnnnnnn.ext, where nnnnnnnnn is the nine-digit number, and ext is the file extension. If we needed a change to the file, we'd file as nnnnnnnnn_hdate.ext, where hdate is the horolog date. And for 18 years, this was just fine.

The code I'm researching loosely follows this flow:

1. My first callback
2. Black box
3. My second callback

I can modify 1 and 3 no problem but modifying 2 is difficult.

However I think that step 2 has some optimization problems, namely:

• instantiates lots of objects
• throws/catches lots of exceptions (not logged)

Is there a way to count these two metrics?

Looking for official guidance concerning the pitfalls of mixing Object Script with legacy MUMPS in the same .INT and/ or .MAC. Thanks, R

Hi community,

what is the best way to determine if a certain property got changed between %OpenId and %Save? Preferably in the %OnAddToSaveSet method.

This document describes considerations around SDDC and HCI solutions for InterSystems Clients.

Software Defined Data Centers (SDDC) and Hyper-Converged Infrastructure (HCI) – Important Considerations for InterSystems Clients

When working with the dateText component in a Zen Application and setting the parameters "format:DMY" and "separtator:/" I cannot save the  right date to the database.

In short, I have a structure similar to :

Class View.A Extends  %ZEN.Component.page{XData Contents [ XMLNamespace = "http://www.intersystems.com/zen" ]
{... <dataController id="a-controller" modelClass="MVC.A"/> <dynaForm id="a-form"  controllerId="a-controller" onsubmit="return zenPage.saveForm();"/>}}

Hi All

I'm sharing this ticket just posted to wrc as I believe it is inconsistent behaviour. and other developers may trip over it....

<wrc ticket>

I have found something that appears to me to be inconsistent
Simple example

set x={"theValue":true} write x.theValue
this correctly converts true to 1

However if " (double quotes are placed around it
eg
set x={"theValue":"true"} write x.theValue
it does not convert and displays the string "true"

!!!!!

The documentation only provides the syntax but does not provide any sample DDL for this case.

I am modifying some DB2 queries to Cache SQL but always meet some errors, please provide a sample query for this case.

Thanks.

Hi,

Please let me know best way to restore single cache database of 300 GB from one server to another with minimum downtime.

Cold backup will take lot of time for 300 GB database size and snapshot backup not possible.

Not sure about cache online backup which take all databases backup.

Hi Guys,

is the there a way that I can make a routine call from one cache to another?

I've a client that still on Cache 2008 and given that JSON is not much supported in V2008 we thinking of installing Cache 2014 in the same server Create a routine that handles JSON (in Cache2014), and then simply call in their current Cache 2008 just make a routine call of that is V2014?

thanks

hi

    I cannot connect to Caché sometimes,   the error message is 

            [Cache JDBC] Communication link failure: Communication error: Connection reset

   and I cannot access the management portal

so I plan to restart  Caché with "ccontrol stop cache"， it prompted "unable to get access to pid table"

what's the problem?

thanks!

I am managing a very large logistic's software company utilizing Cache as the main infrastructure.

I have many customers around the world and I need to upgrade the authentication process add 2 factor authentication, access management, captcha etc.

Does anyone have experience with this ? are there any suggested external software that can be integrated with our infrastructure ?

Hello ISM Community,

Is it possible to copy all the classes in a package to a new package in Studio?

If not does anyone have some ObjectScript code that does this?

In this article I would like to present the RESTForms project - generic REST API backend for modern web applications.

The idea behind the project is simple -after I wrote several REST APIs I realized that generally, REST API consists of two parts:

• Work with persistent classes
• Custom business logic

And, while you'll have to write your own custom business logic, RESTForms provides all things related to working with persistent classes right out of the box.

Hello, I'm trying to install CSP Gateway on Ubuntu 18.04 (Apache) with the installer CSPGateway-2018.1.1.638.0-lnxubuntux64.tar.gz but it doesn't seem to work.  I keep getting access-denied when I try to open CSP-pages or the CSP Management portal.

Does someone have an installation-manual or so ?

Hi all,

Do you know if there is a way to create a Lock that is related to an existing transaction, in the sense that if transaction is finished (commit or rollback) Lock is removed. I ask this because in the following example Lock is there until process is killed.

Example :

TSTART

Lock  +^MyLock

TROLLBACK

I know, that, Caché itself is locking internally a table register  when doing an OpenId with exclusive flag during the transaction life. For example :

TSTART

Do ##class(MyTable).%OpenId(<TableID>, 4) (This internally is creating a Lock +^User.MyTable(<TableID>)
