Overview

Encryption of sensitive data becomes more and more important for applications. For example patient names, SSN, address-data or credit card-numbers etc..

Cache supports different flavors of encryption. Block-level database encryption and data-element encryption. The block-level database encryption protects an entire database. The decryption/encryption is done when a block is written/read to or from the database and has very little impact on the performance.

With data-element encryption only certain data-fields are encrypted. Fields that contain sensitive data like patient data or credit-card numbers. Data-element encryption is also useful if a re-encryption is required periodically. With data-element encryption it is the responsibility of the application to encrypt/decrypt the data.

Both encryption methods leverage the managed key encryption infrastructure of Caché.

The following article describes a sample use-case where data-element encryption is used to encrypt person data.

But what if you have hundreds of thousands of records with an encrypted datafield and you have the need to search that field? Decryption of the field-values prior to the search is not an option. What about indices?

This article describes a possible solution and develops step-by-step a small example how you can use SQL and indices to search encrypted fields.

A feature I recently used in working on ISC internal applications is the ability to send emails on behalf of someone. This is useful when generating system notifications from an application when you want some of them to show up as being from a specific person, perhaps posting comments on a work ticket.

In my case I was updating our facilities work order system for tracking requests. Normally all notification emails are sent from the same noreply email address. I wanted to change that so comments added from the original requester would show up as being from them and stand out.

I have a tablePane ZEN Component and I am trying to get a filter running on the Specimen Id / Lab Number. The SQL is fairly complex with 3 UNION ALL statements joining 4 tables and a couple of lookup tables.

How would I get the filter on SpecId to work for my tablePane? It's not automatically applying the filter for me so I think I need code something.

Using a <FORM>

The OnLoadForm attribute calls a method but doesnt allow definition...

It seems to send pKey and accepts back pValues

Method LoadForm(pKey As %String,
                ByRef pValues As %String) As %Status

Is there any way to send more than just pKey as I need multiple values when loading the form.

A method to convert certain non-readable ASCII characters in a %Stream.FileCharacter object first copies it into a %Stream.FileBinary object and then loops through each character one at a time to find and convert these offensive characters to our interpretation of their readable ASCII equivalents . The loop is sequential (while 'bStream.AtEnd) and is taking too long for large files.

Hi,

I have a stored procedure which would generate a standard Cache String and it would be called through JDBC and I would

dump the result in java console/standard output.

What kind of characters should I use in COS so when output get send back to Java side, it knows it contains new line character ?

Thank for your help.

Hi,

We have a mixture of legacy and new systems, and are grappling with the issue of moving documents between systems.

At the moment we are mostly using file drops and encoding metadata in filenames, but a new supplier (letter transcription) is going to provide a Hl7v2 feed sending MDM^T02 messages with PDF's of letters base64 encoded in the message itself.

We are thinking of asking all our suppliers to go with MDM (or ORU) for sending documents.

I'm interested in the pros and cons of the options; and if there are options I haven't thought of.

Hi Group, I've followed the instructions from the documentation to configure LDAP and Ensemble to authenticate, however, I'm unable to authenticate using an account in the LDAP. The user is able to authenticate in a Linux shell. I have added the ObjectClass of IntersystemsAccount and the 3 group definitions to the schema. Other than adding the user to this group, do I have to change the user's objectClass at all?

This is not on active directory - it is a Linux based LDAP solution (slapd).

Hi,

I am saving 2000 objects of a class in a loop.

In one environment it is taking a total of 86 seconds and in another environment it is taking 0.55 seconds.

The code (the class and the code for save) is same for both the environment. I have Ensemble 2012.1.5.956

Can somebody help me to identify the cause of the discrepancy. Is there any memory or any other setup which may cause the problem.

Thank you in davance,

Susobhan

Studio Keyboard Functions

So I finally decided to try out Atelier after having used Studio for who knows how many years. I primarily edit int files directly and am used to all the keyboard shortcuts in Studio. I was fiddling with the preferences under keys but have not got Atelier to behave very well for:

F2 = Jump to next bookmark

<Ctrl><F2> = Toggle bookmark

<F3> = Find Next, <shift><F3> = Find Previous

I can't find any equivalent to F12 to open the currently highlighted routine and jump to that entry point.

Atelier over https

Can Atelier connect to an Ensemble server that only accepts https connections?

How do I configure that? I did try an ssh into such server and Atelier over that but it didn't seem to work.

Any suggestions?

Thanks,

Chris

Grand Total

How can I create a calculated field that will give me the grand total of a column? For instance, if I have a row that has 200, 300, 500, 600, how do I get the Grand Total?

I have already used the wrench under Column Options as % of Total so, I can't use that option.
