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"
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.
You will notice that I wrote some posts before IRIS was released and refer to Caché. I will revisit the posts over time, but in the meantime, Generally, the advice for configuration is the same for Caché and IRIS. Some command names may have changed; the most obvious example is that anywhere you see the ^pButtons command, you can replace it with ^SystemPerformance.
While some posts are updated to preserve links, others will be marked as strikethrough to indicate that the post is legacy. Generally, I will say, "See: some other post" if it is appropriate.
Capacity Planning and Performance Series
Generally, posts build on previous ones, but you can also just dive into subjects that look interesting.
We are trying to understand how websocket connections from a javascript client may timeout in cache. Does anyone know if and of the session timeout or any other timeouts apply to any synchronous websocket connections? I have not been able to prove that they do timeout at all.
This article explains the basics of OpenVMS file structures, from a Caché prospective, and what you need to know to read and write any OpenVMS file with Caché, even the files with difficult file structures.
We are accessing the InterSystems`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.

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 have a requirement to replace $ZF("%ZSET_DIR","/hold/rsm") to its equivalent Cache Class. The $ZF("%ZSET_DIR") sets the Current folder equivalent to "cd" command in Unix.
I have frequently received this below error message in my ensemble 2009 Cconsole log.
" 11/08-13:05:06:114 (9784) 2 Skipping SET due to compare and swap failed on ^["^^e:\test\data\"]Debug("CalcTotal1") for records in e:\test\data\ addr=39745548 "
Please explain this, am very much trouble with this alert. And also want to know it will cause any system hangsup ?
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?

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.
I have created a asp web service and it is hosted in our internal server. How can i consume that web service in cache class method? It is a soap web service with xml input and xml output. It works fine in all the browser.
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.
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.
Whether you are accessing DeepSee for the first time ever or you are configuring DeepSee on a new instance, there are two common issues that are encountered after clicking on the “DeepSee” option in the System Management Portal.
Here's an easy one for you; before I spend another hour looking for the answer, how do you convert %ArrayOfDataTypes to an array (that could, say, fit into the %session.Data array, or maybe just some array named info()), and of course back again?
