I would like to examine the contents of my OBX-5 field and not route the message if it contains alphabetic characters. I've tried various combinations of the Match and Contains functions, with no luck. Should I be using the COS ? operator or plaini regular expressions?

e.g.

OBX-5 Contains "\D"

OBX-5 Contains "?.A"

OBX-5 Contains "[A-Z]"

I am trying to determine the write-access to a windows-directory, using the method %File.Writeable(). But, this method always returns the boolean "true", even when I have revoked the write-access of Healthshare-user in this directory.

Note:
1) When the same ensemble-service tries to write a file in this directory (which it says is "writeable"), it fails.
2) The method %File.Writeable(...) works perfectly in the case of files.

Any help is appreciated.
Thanks in advance... :-)

Bug killing development tips

Does anyone NOT use a debugger? I can't remember the last time I did. It's not because I don't dislike them, I just don't need to use them. The main reason for this is because I have a certain development methodology that either produces less bugs, catches them at a unit test level, or makes tracking them down much easier.

Here are my tips...

1. Write your own COS cheat-sheet.

All responses are appreciated. I am new to both scripting and CACHE so please bear with me. I am setting up a nightly backup script for freezing cache then backing it up and then thawing it back out. Currently when I enter the freeze command I am getting a response of access denied even though my id has %all access. I've tried passing the userid/password as a parameter in the externalfreeze command and passing it from a file. I've used my id and lastly I used the _system id in the file. What ID should I use for this or am I passing it wrong?

Business rule doubt

Hello guys,

I've built a simple rule , as follows:

Thing is, in rule 2, the operation succeeds, the message reachs BO HL7, but in rule 1 it does not go through. In rule 1, I have two different conditions, but they are linked by an OR and one of the conditions is simply IF 1=1.

Do you guys have any clue on why rule 1 does not reach BO HL7?

Thanks

Random Read IO Storage Performance Tool

New Tool Available

Please see PerfTools IO Test Suite for a later version of the Random Read IO tool.

Purpose

This tool is used to generate random read Input/Output (IO) from within the database. The goal of this tool is to drive as many jobs as possible to achieve target IOPS and ensure acceptable disk response times are sustained. Results gathered from the IO tests will vary from configuration to configuration based on the IO sub-system. Before running these tests ensure corresponding operating system and storage level monitoring are configured to capture IO performance metrics for later analysis.

Class Queries in InterSystems IRIS

Class Queries in InterSystems IRIS (and Cache, Ensemble, HealthShare) is a useful tool that separates SQL queries from Object Script code. Basically, it works like this: suppose that you want to use the same SQL query with different arguments in several different places.In this case you can avoid code duplication by declaring the query body as a class query and then calling this query by name. This approach is also convenient for custom queries, in which the task of obtaining the next row is defined by a developer. Sounds interesting? Then read on!

Hi fellow developers!

Curious if you guys use CreatedAt and LastUpdated properties in your classes?

Created to stamp when the record was created and LastUpdated when it was last updated. Where it can be useful - almost everywhere )) I find it convenient in records sorting (e.g. by creation or last update), in sync (with other systems), and so on, for better analytics.

Do you use it all the time for all the classes?

If don't, why not? What do you use instead?

What property type do you use - %TimeStamp? %DateTime?

What is the best practice to have CreatedAt filled automatically during creation and LastUpdated on every successful save (guess it could be in %OnSave)?

Please share your experience /thoughts?
