Connecting AIS (Logic Apps) to On-Prem resources
Hi,
We’re currently using an on-prem BizTalk ESB to leverage our integrations and I’m tasked with scoping the transition over to AIS.
I’ve figured out the appropriate tooling required and what services we’re likely to leverage within AIS, but there will be a strong dependency on on-prem connections (most of our services are maintained within internal SQL DB’s and Network shares).
I’ve done some further reading on the Azure Data Gateway, and can see that we connect our local SQL DB’s to Logic Apps through it, but is it possible for the data gateway to poll/listen out for SQL data changes?
Thanks
Chris

User Account Control prompts for Windows 10 are too frequent
I’ve been experiencing a frustrating issue with User Account Control (UAC) prompts on my Windows 10 device. It seems like every time I try to perform a simple task, such as installing a new program or updating software, I’m prompted to elevate my privileges. This is happening excessively, and it’s becoming a major annoyance.
So far, I haven’t found anything that seems to work. I’ve also noticed that some apps and programs are able to bypass the UAC prompts altogether, which makes me wonder if this is a problem with the app itself or if there’s something wrong with my system configuration.
I’d love to hear from anyone who has experience with this issue and can offer some advice on how to minimize or eliminate these pesky UAC prompts.

Architecture of Azure Database Migration Service
Azure Database Migration Service (DMS) is a fully managed service designed to enable seamless migrations from multiple database sources to Azure data platforms with minimal downtime. It powers the “Azure SQL Migration” extension for Azure Data Studio, can be used via Azure portal, PowerShell and Azure CLI.
This article explains architecture diagram of Azure Database Migration Service and how the DMS perform migration for different scenarios.
How does a normal migration work?
There are two ways to perform migration for a database from source to Azure SQL Targets as mentioned below:
Physical migration: In Physical migration, Backups from the source databases are used to perform restore on the Azure SQL Target databases. DMS uses Physical migration for migrating to Target Azure SQL VM and Azure SQL MI.
Physical Migration
Logical migration: In logical migration, data rows are read from the source database tables and then inserted into the Target Azure SQL’s database tables. DMS uses Logical migration for migrating to Azure SQL DB.
Note:
In case of logical migration, example for Target Azure SQL DB, Schema migration is a prerequisite before proceeding with data migration.
Logical Migration
How does DMS architecture work?
Overview
Azure Database Migration Service (DMS) is an Azure service that orchestrates migration pipelines to do data movement activities from an on-premises environment to Azure. When a customer creates a Database Migration Service instance (in customer’s subscription), it associates itself with the Azure Data Factory pipeline (in Microsoft’s subscription).
Using this DMS instance customers can start, monitor, and complete / cancel the migration. While DMS functions as an orchestrator, it uses the Azure Data Factory’s Self-hosted Integration Runtime (Migration agent) in case backup files are placed on local SMB file share to copy them to Azure blob container or to perform logical migration to Azure SQL DB (bulk reading data from source and writing on Target). Customer can install the SHIR on a local machine (near to source), then register it using DMS provided authentication keys and associate SHIR with DMS.
Once backups are copied to or let’s say are already present on Azure blob storage container, DMS communicate with Target (Azure SQL VM or Azure SQL MI) resource provider’s restore service to restore these backups from Azure blob storage to respective Target.
Architecture components:
The following list describes the various components of DMS architecture:
Source SQL Server: An on-premises instance of SQL Server that is in a private cloud or an instance of SQL Server on a virtual machine in a public cloud. SQL Server 2008 and later versions on Windows or Linux are supported.
Target Azure SQL: Supported Azure SQL targets are Azure SQL Managed Instance, SQL Server on Azure Virtual Machines (registered with the SQL infrastructure as a service extension in full management mode), and Azure SQL Database.
SMB (backup) file share: A Server Message Block (SMB) network file share where backup files are stored for the databases to be migrated. Azure storage blob containers and Azure storage file share also are supported.
Client Tools: Azure DMS can be used by different client tools like “Azure SQL Migration” extension for Azure Data Studio, Azure portal, PowerShell and Azure CLI.
Azure Storage Account: The blob storage account in customer’s subscription is used to write the backup files from the source and to read from this blob storage container for restoring it on Target.
Azure Data factory: Database Migration Service is associated with the Azure Data Factory’s pipeline. ADF pipeline acts as a placeholder of activities trigger by the DMS’s migration workflow and provides the capability to register and monitor the self-hosted integration runtime.
Self-hosted integration runtime (SHIR): Install a Self-hosted integration runtime on a computer that can connect to the source SQL Server instance and the location of the backup file along with connectivity to Azure blob storage / resources. Database Migration Service provides the authentication keys and registers the self-hosted integration runtime. SHIR act as a compute of the DMS migration’s data movement and can be scaled upto 4 nodes maximum.
Note:
If customers have backup files on local SMB file share or want to perform logical migration to Azure SQL DB, then only Self-hosted integration runtime is needed.
Target resource providers and Restore Service: Target resource provider is a collection of REST operations that enables functionality for an Azure service like restore service on the Target Azure SQL VM or MI. This restore service is responsible for scanning the backups in the Azure blob container, validate, creating a restoration plan, and then performing the restore of these backups on the Target. In case of Azure SQL VM, it is part of the SQL Server IaaS Agent extension and for Azure SQL MI, it is the Log replay service (LRS).
Architecture of Azure Database Migration Service
The following diagram illustrates the DMS architecture workflow:
DMS architecture
The number labels against the workflow defines the migration sequence w.r.t a given scenario (as stated in the key on right side bottom).
And below is the detailed description of architecture workflows based upon the migration scenarios:
A. Migration to Azure SQL VM or SQL MI from Azure blob storage:
1. Customer can use different client tools like – “Azure SQL Migration” extension for Azure Data Studio, Azure portal, PowerShell and Azure CLI to create and migrate using Azure Database migration Service. They can also perform Pre-migration activities like Assessment and SKU recommendations using Azure SQL Migration extension, PowerShell and Azure CLI.
2. Once a customer creates the DMS instance in their subscription, they can use it to perform Azure DB migrations. DMS also creates an ADF instance in the background which runs in Microsoft’s subscription.
3a. Since in this scenario, the customer has already placed the database backups (Full, differential and Tlog) in the Azure blob storage, DMS communication these details to the Target Resource provider’s restore service.
4a. Restore service scans the Azure blob storage container, validate, and creates a restore plan based upon the available backups files.
Note:
It is recommended not to delete any backup from blob container until migration completes as it impacts the restore plan.
It is required to keep the single database backup in a folder and the folder should be in the root directory of the blob container. Alternatively, if the backups are stored in the root directory, they should also correspond to one database only.
5a. Once it creates the restore plan, the Target’s restore service only takes the required backup files and skips the backup files which are not relevant. Example if there are two full backups of same database, restore service skip the older full backup.
6a. After that, backups are restored to the Target with NORECOVERY option. In case of online migration, once customer initiates the cutover, restore service looks for any remaining backup, restore those last backup with RECOVERY and bring the Target DB online. In case of offline migration, as soon as it finds the “last restore file” mentioned by customer (during configuration of DMS migration), it performs restore with RECOVERY and bring the Target DB online.
B. Migration to Azure SQL VM or SQL MI from local SMB backup file share:
1. Customer can use different client tools like – “Azure SQL Migration” extension for Azure Data Studio, Azure portal, PowerShell and Azure CLI to create and migrate using Azure Database migration Service. They can also perform Pre-migration activities like Assessment and SKU recommendations using Azure SQL Migration extension, PowerShell and Azure CLI.
2. Once a customer creates the DMS instance in their subscription, they can use it to perform migrations. DMS also creates an ADF instance in the background which runs in Microsoft’s subscription.
3b. To copy the backup files from local SMB backup file share to Azure blob storage container, DMS inform the ADF factory pipeline and request for a copy activity.
4b. This copy activity request is carried out by SHIR, which acts as a Migration agent, running on a nearby computer w.r.t to the source. To do so, SHIR node should be able to communicate with source and Azure resources.
Note:
The connectivity required for SHIR to function is mentioned here.
For SHIR related best practices, refer here.
5b. SHIR then read the meta data of backup files from the local SMB backup file share, ensuring the backup files should belong to the mentioned database. After copying the backup files, SHIR keeps on scanning the file share for new backup files after every 1 min interval.
6b. These backup files are then transferred to an Azure blob storage container.
7b. Restore service scans the Azure blob storage container, validate, and creates a retore plan based upon the available backup files.
Note:
It is recommended not to delete any backup from blob container until migration completes as it impacts the restore plan.
It is required to keep the single database backup in a folder and the folder should be in the root directory of the blob container. Alternatively, if the backups are stored in the root directory, they should also correspond to one database only.
8b. DMS informs the Target resource provider’s restore service after copying finishes. As per the restore plan, Target’s restore service only restores the required backup files and skips the backup files which are not relevant. Example if there are two full backups of same database, restore service skip the older full backup.
9b. After that, backups restored to the Target with NORECOVERY option. In case of online migration, once customer initiates the cutover, restore service looks for any remaining backup, then restore those last backup with RECOVERY and bring the Target DB online. In case of offline migration, as soon as it finds the “last restore file” mentioned by customer (during configuration of DMS migration), it performs restore with RECOVERY and bring the Target DB online.
C. Migration to Azure SQL DB:
1. Customer can use different client tools like – “Azure SQL Migration” extension for Azure Data Studio, Azure portal, PowerShell and Azure CLI to create and migrate using Azure Database migration Service. They can also perform Pre-migration activities like Assessment and SKU recommendations using Azure SQL Migration extension, PowerShell and Azure CLI.
2. Once a customer creates the DMS instance in their subscription, they can use it to perform migrations. DMS also creates an ADF instance in the background which runs in Microsoft’s subscription.
3c. Since it is a logical migration, DMS inform the ADF pipeline to initiate migrate schema and/or copy data rows activity from the selected tables based upon the configuration provided by the customer.
4c. This activity request is executed by the SHIR, acting as a Migration agent and running on a local computer near to source. To do so, SHIR node should be able to communicate with source and Azure resources.
Note:
The connectivity required for SHIR to function is mentioned here.
For SHIR related best practices, refer here.
5c. SHIR reads the schema / data rows from the selected tables. It performs SQL bulk copy to read the data.
Note:
To improve the Azure SQL DB migration performance, refer here.
6c. It is also responsible to write this data on the Target Azure SQL DB using bulk insert. On Target Azure SQL DB, first schema migration is performed (if configured by customer) and then the data row movement starts. Once all the data rows are inserted on the Target, DMS perform post copying activities like creation of indexes etc. before finishing the migration.
Note:
In case of Target Azure SQL DB, Schema migration is a prerequisite before proceeding with data migration.
In case of any error while migrating schema, if error does not belong to the selected table, then schema migration continues later followed by data row migration.

Baseband IQ to RF Signal Generation
Body:
I’m working on the IQmod example in MATLAB and attempting to generate a 4FSK signal for transmission at 150 MHz. However, I’m unclear about how to control the center frequency of the transmitted signal.
Current Approach:
I’ve tried using the center frequency option in the inport block, but it doesn’t seem to affect the transmission frequency.
The iqmodulator block offers a local Oscillator option, but its purpose in setting the center frequency isn’t entirely clear.
My Question:
How can I properly set the center frequency to 150 MHz for transmitting the 4FSK signal using the IQmod example? Should I be modulating the baseband signal with a carrier at 150 MHz before feeding it to iqmodulator? Or is there another approach within the existing structure?
Additional Information:
I’m using a sampling rate of 1 MHz for the IQ data.Body:

127.0.0.1:31516 – Message service fatally disconnected
Hi,
I have a problem with Matlab (both R2023b and R2024a) not being able to resume after PC wakes from sleep mode. If Matlab is open when trying to put my PC to sleep, it stalls for several minutes preventing it from sleeping (until some process times out I guess and it finally enters sleep mode). Then, after it wakes, Matlab throws this error that Message service was disconnected at a specific localhost port (see title, the port number can vary). I followed advice from other posts (https://www.mathworks.com/matlabcentral/answers/514453-message-service-fatally-disconnected, https://www.mathworks.com/matlabcentral/answers/1637690-session-locks-when-connected-to-internet-after-disconnect-it-eventually-unlocks-with-matlab-error, and links within) that suggested to reset the preferences folder in AppData and download help documentation to local storage, but neither helped. This issue started in R2023b, recently I’ve upgraded to R2024a, but the issue still persists (this means I have a fresh install of R2024a that does this).
This disconnect issue causes the session to "freeze" – I can still write code into scripts and the GUI still responds, but I cannot execute any lines, and any edits in scripts cannot be saved (meaning that anything I write/edit will be lost). Restarting Matlab "fixes" this (until the next sleep mode), but that is not a solution for me. I use Windows 11 Home 23H2 with a Ryzen 3600, the Matlab is an Academic Total Headcount licence if any of that matters.Hi,

This disconnect issue causes the session to "freeze" – I can still write code into scripts and the GUI still responds, but I cannot execute any lines, and any edits in scripts cannot be saved (meaning that anything I write/edit will be lost). Restarting Matlab "fixes" this (until the next sleep mode), but that is not a solution for me. I use Windows 11 Home 23H2 with a Ryzen 3600, the Matlab is an Academic Total Headcount licence if any of that matters. matlab startup, message service MATLAB Answers — New Questions
How can I solve this problem?

Why is my Windows 11 battery life dropping faster than before?
I’ve been using Windows 11 for a few weeks now, and I’ve noticed that my battery life is dropping significantly faster than it used to. I’ve tried to troubleshoot the issue, but I haven’t been able to find any solutions. I’m using the same laptop and same usage habits as before, but my battery life is now only lasting around 4-5 hours, compared to 6-7 hours on Windows 10. This is a big issue for me, as I need my laptop to last throughout the day.
I’d love to know if there are any specific settings or tweaks that might help improve my battery life. Any advice or guidance would be greatly appreciated!
