Windows, Caché and virus scanners

I have seen a customer problem recently where the use of a virus scanner running over Caché databases was causing intermittent application slow downs and bad user response times.

This is a surprisingly common problem, so this short post is just a reminder to exclude key Caché components from your virus scanning.

Generally virus scanning must exclude the CACHE.DAT database files and Caché binaries. If an anti-virus is scanning CACHE.DATs and InterSystems files then system performance will be significantly impacted.

NewBie's Corner Session: 5 Operator Precedence

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Click on the Caché Cube in your system tray and select Terminal to try out the commands.

Order Precedence means the order in which mathematical operators are executed. In a Mathematical expression, you may have Multiplication, Addition, Subtraction, and Division. Which of these are executed first, second, third, etc.?

The basic Operator Precedence of mathematics is:

I'm pleased to see the new Source Control menu in the recent 1.0.165 build. This gives me access to the features of the same server-side source control class as Studio has always supported. It is particularly relevant for our Deltanji source control tool.

Our class makes use of CSP to serve up some dialogs through which the user controls the source control operation. Two observations so far:

1. In Atelier the window you display our CSPs isn't resizable. In Studio it is.

NewBie's Corner Session 4 The Plus Sign and Concatenation Operators

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Click on the Caché Cube in your system tray and select Terminal to try out the commands.

Plus Sign (+) operator

Typically, the Plus sign (+) adds two numbers together. This is true in COS (Caché ObjectScript), but COS uses it in other ways as well.

Set the variable X to a value of +12

NewBie's Corner Session 2 Variables Set and Write commands

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Session 2 – Click on the Caché Cube in your system tray and select Terminal to try out the commands.

Variables

Like other computer programming languages, Caché uses Variables and the values they represent to control programming. Variables are elements that represent data values. Manipulating and interrogating variables is at the root of programming.

mySQL data importer tool

Hi,

If you want to import data from a mySQL export file (exported with mysqldump), you will find here a little script that could help.

Only the INSERT commands in the sql file are executed into Caché. Indices are not computed for better performance.
%NOINDEX, %NOCHECK and %NOLOCK are generated on each INSERT line.

Currently, the file can not contain a "),(" pattern inside the values part of the INSERT command. If this is the case, the line is skipped. This feature may be implemented in the extractValuesList method.

Huge icon on Atelier's Help menu

I'm using Atelier 1.0.145 on Windows (x64). When I open the Help menu from the menubar the final entry (About Atelier) has a huge version of the Atelier icon alongside it. This distorts the menu. I can't post a screenshot here because my simplistic screen capture tool causes the faulty menu to close. But the large icon I see is also (correctly) displayed on the About box itself:

Greetings! This article describes yet another simple way of creating installers for the solutions based on InterSystems Caché. The topic covers applications, which can be installed or completely removed from Caché with one action only. If you are still documenting installation instructions that have more than one step to do to install your application — it’s high time you automated this process.

Hi!

Want to share with you code snippet of try catch block I usually use in methods which should return %Status. 


{ 
 try {
  	$$$TOE(sc,StatusMethod())
 }
 catch e {
 	set sc=e.AsStatus()
 	do e.Log()
 }

Quit sc 
}

Here $$$TOE is a short form of $$$TROWONERROR macro.

Inside macro StatusMethod is any method you call which will return %Status value. This value will be placed into sc variable.

Feedback on Product Documentation?

We are in the process of putting a new UI on the existing product documentation, including a mobile-optimized view. We also plan on releasing additional "solution based" documentation that is targeted at common usage scenarios or important configuration tasks.

We are interested in your feedback on our current product documentation - what you like and dislike and especially what changes you would expect to see to make it as useful as possible.

You may experience errors executing Java programs that rely on the JAVA_HOME environment.

For example when Create PDF from this pivot in DeepSee or in this case, outputting a Zen Report as PDF.

You can verify the PDF generation configuration by clicking on the Verify Now button on the Management Portal System > Configuration > Zen Report Settings page:

Hi,

I'm posting this for the benefit of others. Not often one changes certificates in Cache, at least in my case. I run a system, that uses certificates to encrypt SOAP messages, and since the last time I ran it, my certificates expired.

So I renewed them using our PKI tool, so far so good. I gave all (3) certificates the same names (and filenames too) as to those expired, thinking that everything would just work fine next time I call the SOAP service.

Unfortunately, I got trapped.

Presenter: Danny Wijnschenk
Task: Help people make better decisions by letting application deal with all the data.
Approach: As an example, we’ll extend a demo asset management application for portfolio and trade compliance, using iKnow technology to translate agreements into rules that ensure portfolio compliance prior to trade execution.

In this session, we’ll discuss how easy it is to extend a classic application that deals with straightforward transactions, to also offer insights and actions based on more complex, unstructured data. We’ll present a use case on portfolio compliance from the financial services industry.

Task: Use an LDAP schema that differs from the provided default
Approach: Give examples of customized LDAP schema development, using LDAP APIs and ZAUTHORIZE

In this session we explore the various options of for working with LDAP as an authentication and authorization framework. We will look beyond the simple LDAP schemas into working with more complex LDAP configurations that incorporate application level security information.

Presenter: Andreas Dieckow
Task: Securely store sensitive information
Approach: Give examples of data-at-rest encryption and data element encryption

Description: In this session, InterSystems will showcase how to use API calls to programmatically do everything using your own scripts. This approach is highly effective if you have recipe based settings and configurations that you would like to roll out in a controlled and fast fashion.

Problem: Implement Security relevant information correctly and how. Examples are Credit Card information, Sensitive information (e.g. SSN, Classified Information)

Solution: Data-at-rest encryption and data element encryption

Task: Apply SQL security to multiple servers in a distributed system
Approach: Provide code samples for using new API calls to apply SQL security statements to multiple instances of our products

Description: The requirement that started at all. See examples on how to use this new feature and integrate it into your application by discuss code examples.

Problem: SQL Security is local to the instance and most of time driven by customer application code. That it is only local to the instance and is not automatically going to other instances requires a solution.

Solution: With application code use new API calls to issue SQL security statements that is applied to multiple instances.

Hello!

Link: https://demo.cachequality.com

In this presentation, developer oriented, we will cover this tool, how it works, how you can use it/administer it, etc. Duration 30 minutes.

The topics will include:

  • a short presentation of Caché Quality and SonarQube (which this plugin uses),
  • a demonstration of the rules and how to tailor them to your need.

Questions will be more than welcome! Hope to see you there!

And a big thanks to Evgeny Shvarov who made this possible!
