Purview Account
Just started using Purview and can see that data in my MS cloud has already been categorised and when I create new files they are categorised too. But I do not have a Purview Account – do I need one ?
I do not see the Data Map menu despite reading articles about putting my account in various groups but now wandering if its because we do not have a Purview Account.
If i created a new SIT I would have to go to each SharePoint site and have re-index it which I would prefer to have it done to all sites at once which I believe you can do in the Data Map which we cannot see.

I’d like it to search only within two document libraries I have on the page, I have tried using the path to this location but and still getting results from other locations.
I’m new to this so i could be missing something important.
What i would like is a search box (i have this and its connected to the results) and results just pointing to those two libraires.
Thanks in advance.

Renew
Hi all,
We purchased some licenses from one vendor last year which are due to expire in a few days.
We have since renewed our licenses with a different vendor, however I can see the following from the “old license”.
The subscription says “On, renews on 13/7/2024”.
Does this mean it will auto-renew on the 13th? Previously it would just have expired on the 13th.

Can’t see anything in any GUI tools either.

Odd bug when selecting 32 columns in source query of copy data task
I have been fighting a very odd issue in a pipeline this morning and can reproduce the issue at will.
Imagine a simple pipeline with a copy data task using a SHIR.
For the source query, if I specify 32 columns in the query – it errors with a message that it cannot find the first column in the dataset.. If I specify 31 columns, or 33 columns its fine.. It doesn’t matter what order the columns are in, doesn’t matter what columns I choose, or the names, or whatever, but the moment I choose 32 columns – It errors with a message that it cannot find the first column (whatever I select as the first column)
Repro – Copy data task, source query =
SELECT 1 AS col1

, 3 AS col3
, 4 AS col4
, 5 AS col5
, 6 AS col6

Capture and review .Net Profiler Traces on App Service (Windows)
Access the Azure Portal and navigate to the desired App Service.
Navigate to “Diagnose and Solve Problems” -> “Diagnostic Tools”
Choose “Collect .NET Profiler Trace” option.
Configure the trace options to gather data from the specific application instance, including thread details.
Reproduce the issue at step 2.
Access and examine the generated report.
In the demo application, a delay of approximately 20 seconds was observed. Refer to the browser network traces provided below.
Analyze the profiler traces to pinpoint the cause of the reported delay.
After examining the demo app’s code, it was evident that a deliberate 20-second delay was introduced in the Privacy method within the Home Controller.
Note: Default profiler log collection time is 60 seconds and it is possible to increase the default profiling duration by setting an application setting IIS_PROFILING_TIMEOUT_IN_SECONDS with a maximum value of 900 (i.e. 15 minutes).

The particle swarm optimization algorithm optimizes the scale factor and quantization factor of the fuzzy PID controller
I want to use the particle swarm optimization algorithm to optimize the scale factor and quantization factor of the fuzzy PID controller, how do I do that? If I want to adjust the temperature of my cabin by controlling the speed of my compressor, can I set the difference between the actual temperature of the cabin and the set temperature as my objective function? My optimization goal was to control the cabin temperature, so that when there was a sudden disturbance from the outside world, my cabin would fluctuate less and correspondingly faster.I want to use the particle swarm optimization algorithm to optimize the scale factor and quantization factor of the fuzzy PID controller, how do I do that?
