There are three things most important to any SQL performance conversation: Indices, TuneTable, and Show Plan. The attached PDFs includes historical presentations on these topics that cover the basics of these 3 things in one place. Our documentation provides more detail on these and other SQL Performance topics in the links below. The eLearning options reinforces several of these topics. In addition, there are several Developer Community articles which touch on SQL performance, and those relevant links are also listed.

There is a fair amount of repetition in the information listed below. The most important aspects of SQL performance to consider are:

1. The types of indices available
2. Using one index type over another
3. The information TuneTable gathers for a table and what it means to the Optimizer
4. How to read a Show Plan to better understand if a query is good or bad

Hello everyone,

Does anyone know how to create integration tests using the Cache unit test framework in order to test an Ensemble production?

For example, what would be the best way to create automated tests for a BPL that calls multiple business operations (SQL, WebService ...)?

Should we create some kind of mock service/operation to simulate the response from the business operations ?

In the previous article, I have demonstrated a simple way to record data changes. At this time I have changed the "Audit Abstract Class" which is responsible for recording audit data and the data structure where the audit log will be recorded.

I have changed the data structure to a parent and child structure where there will be two tables to record the "transaction" and the "fields its values" changed on that transaction.

Take a look at the new data model:

I know %CSP.Daemon is supposed to clean up old CSP sessions (?). In my management portal, under System/ License Usage, I see 33 "Units" used (and there are 33 licenses in use), but usernames from old IP address and that are not being used. Their active times are often in the millions of seconds. They are not "on" the system right now.

At most, only 3 users are on the system right now.

Are these supposed to be cleaned up? Can I clean them up programmactially, and how would I know if they're not active?

Thanks,

Laura

I want to use the Regex Matcher to strip HTML tags, but I get a REGEX error. Can anyone explain what I'm doing wrong?

When testing a new routing rule, one frequently encountered problem is that messages that seem like they should be getting routed to a target component are not getting routed. This article aims to describe how to determine why the message didn't get routed.

1. Check the Event Log for the router to make sure there wasn't an error evaluating the rule or running any transformations referenced by the rule. If there was, debug that error first.

Hi,

I have an Ensemble DTL which is suppose to translate the inbound XML document to an outbound XML document.

I need to test if a particular XML element exists, to perform some translation.

In the DTL I have the following,

<if condition='source.{element1.element2.element3}'>

<true>

    // do something

</true>

</if>

How do you use if statement to test the source XML document to see if a particular element exists in the source doucment.

Thanks,

Hi folks!

Is there a one line command to map class package A to Namespace ASPACE?

Hi, I am trying to transform a message to meet a third party specification, and would like to know if you can advice me on how to separate a single OBX segment into several segments based on a '.'

I would like to separate the segment where the . [marked in red] is into another OBX segment. So the next segment would be:

I'm using Cache SQL and want the ability to choose a specific index.

I've boiled the problem down to one table and simplified the query down to

SELECT *
FROM Registration.PatResp
WHERE SchedApptNum=8450022

SchedApptNum is indexed, but instead of using that column, "Show Plan" indicates that it's looping through the entire Registration.PatResp table on Id (the primary key for the table).

I've done a tune-table with no change.

Currently, we have an application running in one namespace ("Database B") that has globals and routines mapped to another database ("Database A"). After enforcing clean up on Database A, we found that 90% of the disk is free. We would like to compact Database A and release the unused space. However, we are running OpenVMS, which seems to be the issue.

For databases consisting of only globals, we are able to use ^GBLOCKCOPY; however, we need to ensure that the routines and mappings are also copied.

Hello,

Hi all,
I am trying to execute a query like the below code.
set statement = ##class(%ResultSet).%New("some_class:query_method"). // here query method is empty and with rowspec some columname

statement.Execute(param1)

I want to fetch data type of column value returned from above. eg - Name - VARCHAR, amount - INTEGER etc.
How can I get it. Or if not possible directly. Is there any other way to validate or get datatype of values returned. Line we have type() in python3

Too often users finding themselves in need of a software solution do not consider “open source” vs. “proprietary” alternative. Most of them either have their go-to favorite developer or just google for reviews and ready-made answers. However, this alternative must be the starting point of their search, as the decision has the most consequences.

It is not an overstatement to say that open source is the future of technology, albeit, it has its own unique challenges. Here is what users, especially corporate users should consider choosing the software for their business needs.
