Dear,

I am beginner with this system.

I would like to do a migration of Cache.

I have at this time a windows XP with Cache 2007.1.5.802.0.7279.

I already install on a windows 10 the version of cache 2017.1.1 Build 111

The question is how do i have to transfer DB from the old pc to the new one?

Thank you very much for your help.

Hi

I am new to cache and accessing it using odbc (other data sources) from excel. I need to know how to get hold of the number of rows for each every object in my current schema.

I can find table name using following query but I need number of rows to estimate size of each table.

SELECT *
FROM %Dictionary.ClassDefinition ClassDefinition

The Index on a String field

I noticed that the subscript of the index map is actually the collated field (%SQLUPPER).

Is String the only data type going through this transformation? Any other data type would also go through this transformation?

Thanks.

Cache 2016.2.1.603 for windows)

I created a few classes and one class called jitPod.Api.toServer.additionalConsignments and realised even before I did any work,, that the word "Api" (note capital A) needed to be "api" (all lowercase)

it would not allow copying the class to the lowercase name because the directory already exists (i understand that)

so I exported the class to an XML, edited the xml to become lowercase "api" , deleted all the classes (and directory name) and re-imported the class.

Problems encountered with Java Gateway

Problems encountered with Java Gateway

I am writing a framework for use on the Java Gateway. The role of the framework is:

1. Import the framework jar file into ensemble studio (test completed);
2. In the framework jar, handle the related functions of the remaining jar files (the rest of the jar files are written by colleagues).

The general idea is as follows:

Send: Ensemble Java Gateway -> Framework Jar -> Plugin Jar (colleagues write, processing data).
Returns: Plugin Jar (processed return data) ->Framework Jar->Ensemble Java Gateway.

Git behavior

We are going to start using Git within Cache.

One question came up - if the branch that you checked out does not have the class or mac file, what is the correct thing to do?

Should we delete from Cache or should we just keep it?

I'm leaning more towards deleting it because Cache should reflect what is in your work folder in git. But other team members are saying to keep it.

Hi,

The following sql statement is working through the SMP but couldn't make it work through the code.

The table is a linked table to oracle db.

Tried to change the date property in the linked table class from %Date to %String and also tried using %SQL.Statement and %Library.ResultSet

this work through SMP:

INSERT INTO PACKAGE.SOME_TABLE_NAME

(EFFECTIVE_START_DATE,MORE,DATA,HERE)

VALUES (to_date ('2018-04-01','yyyy-mm-dd'),123,456,789)

In the code i'm using '?' in the statement for the parameters.

I am working with a client to try and export a set of tasks defined in the Task Manager from one system to another. I am not seeing any API for this. I can query this information in SQL. So I tried to use the Data Export Wizard from the System Management portal in the SQL window. Export was fine. Importing failed with a "can't insert into read only field" error. Looking at the class definition does not help since the implementation details are not visible.

So how would one accomplish this? Export scheduled tasks from one system to another?

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.

I am working on a TrakCare JIRA issue that requires accessing class properties in a different installation of TrakCare on another machine. For instance, I need to compare the deprecated items in the current version of TrakCare to the deprecated items in a previous release. Is there anything in the built in classes that will allow me to do this, or is it something I'll need to do with a SQL stored procedure or something else I haven't thought of?

I downloaded and installed the trial version of Caché.
it is installed in c:\intersystems\Trycache
I changed the system environment settings so that
GLOBALS_PATH = c:\intersystems\Trycache
and PATH includes c:\intersystems\Trycache\bin
Caché works, and I can login, use the globals, etc...

SQL calculated property rollback

Greetings all,

I have a quick SQL question. I am working with a class, which has a calculated property, which in turned indexed.
The calculation for this property is created based on another property value via:
SqlComputeOnChange = attributes - so basically every time I add a property attribute to my class, my new property
is calculated based on some SqlComputeCode which calls some class method.

That initial setup works as designed.

Embedded SQL bug?

Hi

Is this a bug? We came across it on an older version of Cache but I've also just tried it in version "Cache for Windows (x86-64) 2017.2.2 (Build 865U)" and got the same result.

Create a Class like so:

We have a Cache database in Azure, and want to expose it as an OData source (link).

My first attempt was to use Microsoft's Visual Studio 2017 and Entity Framework to create the data models...but it seems as if EF and Cache don't work together. (I do have those instructions from 2013, but they don't work. (See other post. Best answer seems to be "migrate to IRIS 2019.1.")

Is there any other form of OData support?

Hi,

We are using Cache to generate HTML pages (complete with Javascript), which we are reading in an Android phone App's WebView.

If, when we generate HTML as follows:

<html>

<body bgcolor='red'>

Hello World

</body>

</html>

Reading this is iPad gets what you would expect, a red page with Hello World written in it.

However in Android phone, the page is both white and blank.

Hi All,

Can someone help me getting the security features & standards which InterSystmes Cache adheres to ISO 27001 & other security & privacy standards.

Also if you can tell me the algorithm used for database encryption & key strength by default.

This is required for a security audit.

Thanks in advance.
