Caché

A new Health Connect customer has a few experienced Java folks on their interface team. As they get more into Health Connect and learn Caché ObjectScript they thought it would be useful to have a list of common Java statements with an equivalent statement in ObjectScript. They mentioned string manipulation as an example, but would be interested in other areas as well.
 
This seems like something that is probably already floating around somewhere. Does anyone have something like this or other "COS jumpstart for Java devs" materials?

Thanks,
Marc

Question:

Where can I find the openssl command line tool for Windows?

Answer:

The openssl command line utility comes with Unix, but not with Windows. It is used for working with security certificates.

The main site is

https://www.openssl.org/

There are no binaries on this site but in the Community section there is a link for binaries which leads to:

https://www.openssl.org/community/binaries.html

I'm working on a REST service which will include a binary stream as a request property. I'm currently encoding the stream as BASE64 and passing it as a string value, but I was wondering if there is anything in the Caché JSON support that may be a better fit for encoding this data? Thanks Chris

Microsoft Office has components for using in third party applications: COM Objects for C++ and Interop Assemblies for .Net programming.

Many Cache projects used to include calls to those libraries. However, recently this solution started being problematic.

There are two main reasons - legal and technical. Let’s check the details.

Microsoft technology support

Microsoft is supporting Office Automation only for desktop computing. 

It shall not be used for server computing, as they offer Sharepoint for this scenario. Have a look here:

Hi all,

We've found that in most cases when we open a new CSP session the CGI varaiable %CGIEVAR("HTTP_COOKIE") contains the client name.

It looks like that : "state=SYSADM%3A0; Username=Urish; CSPWSERVERID=Cache for Windows (x86-64) 2013.1.1 (Build 501_1_13062) Sun Aug 11..."
In some other cases this CGI only contains  $zv - like "CSPWSERVERID=Cache for Windows (x86-64) 2013.1.1 (Build 501_1_13062) Sun Aug 11 2013 23:20:33 EDT"

Myself and the other Technology Architects often have to explain to customers and vendors Caché IO requirements and the way that Caché applications will use storage systems. The following tables are useful when explaining typical Caché IO profile and requirements for a transactional database application with customers and vendors.  The original tables were created by Mark Bolinsky.

In future posts I will be discussing more about storage IO so am also posting these tables now as a reference for those articles.

This is a list of all the posts in the data platforms capacity planning and performance series in order. Also a general list of my other posts. I will update as new posts in the series are added.


Capacity Planning and Performance Series

Generally posts build on previous, but you can also just dive in to subjects that look interesting.

Hi All,

We are accessing the intersystem`s cache database via UNIX ODBC and displaying the data in PHP website . Recently we have upgraded the PHP version to 5.6.  We are getting the nondisplayable characters (�) for only strings. But the numbers and date fields are displaying correctly. 

While querying the database via ISQL everything working fine (No Special characters).

I have looked around the internet and found the PHP 5.6 changed the default character to UTF-8.

For this issue anything, we can do from cache side.

cache version :

Hello, I would like to know if CACHE has any limitations on uploading files.

Why am I asking this, why am I going through a problem here.

What happens is that when uploading files or images that are larger than 2.7 MB CACHE is limiting the size to 2.7 MB, any file larger than that is saved corrupted.

Already at the time of uploading the file or image, CACHE is limiting the size of the file to 2.6 MB.

I tried to make atelier look more like XCODE with this simple trick or tip: change the default font to SF Mono and size 14.

To do it I did:

1) Install SF Mono font in the system which is the default font for XCODE and needs to be installed in order to use it.

You can find it in: /Applications/Utilities/Terminal.app/Contents/Resources/Fonts

Double Click SFMono-Regular.otf file and install it. You will get a warning of "serious problems" but it will work all right.

Thanks for all replies in advance.  In monitoring our audit log we are getting the error below.  We have 4 different servers running CACHE  2014.1.1 and this is happening on all 4 of them.  I have not been able to find what process is trying to logon but it is happening every 30 minutes.  We have no user processes that are running so this has to be a CACHE process.  Does anyone have an Ideal what could be running to cause this?  What kind of trace can I run to determine what process is running it?

I need to catch the user using a bookmark to get into the application in the 'middle'; i.e. the user is getting into the application not  at the home page.  I've tried OnPreHTTP to redirect, but I can't catch the new session, and it doesn't redirect.

How can you redirect to the home page upon login?

Thanks,

Laura

In this post I would like to talk about the syslog table.  I will cover what it is, how you look at it, what the entries really are, and why it may be important to you.  The syslog table can contain important diagnostic information.  If your system is having any problems, it is important to understand how to look at this table and what information is contained there.

This is the first article in a series discussing how to regain disk space from Caché databases at the operating system level. This introductory article discusses Caché database growth and gives an overview of various methods you can use to return unused disk space that is allocated to database files back to the file system. But before we talk about returning space to the file system, let’s first review how does it get allocated in the first place.

Beginning in Caché 2013.1, InterSystems introduced Outlier Selectivity to improve query plan selection involving fields with one atypical value.

In this article, I hope to use an example 'Projects' table to demonstrate what Outlier Selectivity is, how it helps SQL performance and a few considerations for writing queries.

Hi,

I have a problem which i think has a simple solution but which i and others haven't yet cracked. I want to display text output to a text box in monospaced font. At the moment the style sheet is shown below, I have tried various other options such as specifying a specific font such as Courier New.  None of the browsers I have tried (Safari, Firefox on OSX, IE) display as monospace, although the last 2 come close. I wonder whether I need a <pre> tag, but I can't see how to do that in Zen.

Suggestions?
