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.

DeepSee Tips & Tricks: Auto-execute

By default, Analyzer executes queries as components are added. Often, there are times where you may know exactly what you are looking to do, and you do not want Analyzer to execute 5 queries as you drag and drop items onto rows/columns and select your filters. This is where toggling Auto-execute off can help.

Hi,
I've organized my repository using TortoiseSVN. I was careful to use only svn commands while creating my file structure. Now all Subversion commands are working at the command line but not from within my IDE (Cache Studio). Basically I'm trying to write a plug-in for my IDE to use Subversion from within the Studio. Trying to integrate Subversion into my IDE, something like Subclipse, but for Cache Studio. The error occurred after reorganizing my code into directories. For example at the command-line, svn info and svn status and all other commands work perfectly. All Subversion commands work at the command prompt!

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

Trusting the code you import

As more people join Developer Community, and with increasing efforts to promote code sharing, I'd like to draw fresh attention to this post I wrote a year ago. It spotlights a feature within the class compiler which is both useful and dangerous. When importing code (e.g. from an XML export of classes received from someone), it's worth considering the risks.

Even if that post doesn't seem relevant to you at the moment you may wish to note it for the future. A handy way of doing this is to click the star icon at the end of it.

Hi!

Consider I have a class Package.Data with Property UniqueStringValue as %String.

I introduced the Index for this property:

 Index ValueIndex on UniqueStringValue [Unique];

It works well. But if I try to check if there is an object with the certain value in code like this:

if ##class(Package.Data).ValueIndexExists(value)

this expression fails, if value="value", even if there is an instance with instance.UniqueStingValue="Value"

How can I set the index to prevent saving case sensitive values in this class?

Collision for SHA-1 hash algorithm

The recent announcement of a collision for the SHA-1 hash algorithm has caused some consternation:

https://shattered.io/

Here is some background to help put this in perspective.

Cryptographic hash functions can have a variety of properties. The property at issue here is:

"Collision resistance - it is computationally infeasible to find any two distinct inputs x, x' which hash to the same output, i.e., such that h(x) = h(x')."

(Menezes, van Oorchot, and Vanstone, "Handbook of Applied Cryptography", section 9.2.2)

Hi everyone, I have and Zen Mojo application, it's all working but I have some doubts about what is recommended to use: There is some reports of employees, for example, and actually I'm using some plugins : "Excelent export" to generate Excel reports and "jspdf" to generate PDF reports in client side.

I have an REST service, that receives the request, process and returns JSON, after client side receive the response it's processed.

- This can be slow/bad in applications with large data?

- It's better/recommended to use ZenReports even with ZenMojo applications?

While I can see the benefits that $ZSTORAGE could have if used properly, I have not seen it used in the environments I have worked in. I was wondering if there are any developers that promote its usage.

If used properly, I would imagine it could be highly effective in maximizing free memory since some processes will never go over X amount, while others may very well need much more.
