Failed to generate a user instance of SQL Server - asp.net

I'm receiving this error
Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed
My solution was: execute this query
exec sp_configure 'user instances enabled', 1.
GO
Reconfigure
later, deleted this folder :
C:\Documents and Settings\{YOUR_USERNAME}\Local Settings\Application Data\Microsoft\Microsoft SQL Server Data\{SQL_INSTANCE_NAME}
and restart my computer. !
ok , when I restarted my computer ,I had success ,but every time when I restart the visual studio and my web application , I receive again this error .
What can I do?

Would could cause a Postgres exception: 42501: must be a member of the role whose process is being terminated or member of pg_signal_backend?

I've been running component tests in a .NET 5 application using LightBDD. In each test we bring up an instance of an ASP .NET core "application" that we connect to via grpc. At the end of each test we shut down the "application".
This "application" starts a connection to a Postgres instance (in the tests this is constantly running locally in Docker and is not restarted between tests) and then closes it at shutdown.
In a sequential run of 30 tests I got the following error twice (separated by about 5 successful tests):
Postgres exception: 42501: must be a member of the role whose process is being terminated or member of pg_signal_backend
I haven't been able to reproduce it since. Does anyone know what potentially could have caused this intermittant issue?
You get that error if you are trying to cancel a transaction of a different database session or terminate such a session, but that other session is with a different database user.
The error message informs you what privileges you need to do that: you either have to be the same user (or a member thereof), or a member of pg_signal_backend or a superuser.

Windows Server 2016 mount shared folder as disc permanently also on restart

I'm have local access to a shared folder with credentials.
net use Z: \\server\folder /u:user /persistent:yes passwd
The files in this folder are to be used by other processes.
The problem is that when the machine is restarted, the connection is lost, meaning that I can see that the Network Device Z is there, but it does not automatically connect to it, so that the processes have no longer access to the folder.
I have tried several solutions with no avail:
Creating a Windows scheduled task to run a script with 'net use Z:...',
a. with my_user I get this error in Event Viewer: "The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID"
b. with System, I get no errors but the connection is not created.
I've tried to log stdout and stderr to debug the script, but it does not even
create the log file. (The used script is shown below)
#echo off
'> map.log 2>&1(
net use Z: \server\folder /u:user /persistent:yes passwd
)
Crating a Symlink was another solution I had found, but it is not suitable for my case,
because it does not allow credentials. It seems that the resource has to be either
unprotected or already available locally.
Creating a Startup Script from Local Group Policy Editor, I get the same error in
Event Viewer
Running 'net use Z:...' via a Python script installed ad Windows Service,
import subprocess
proc=subprocess.Popen(r'net use Z: \server\folder /u:user pass', shell=True)
out, err = proc.communicate()
print("out:%s, err:%s"%(out,err))
If I run the python script manually, it works, while running it as a service creates a
disconnected drive.
Can anyone give me an advice on how to proceed?
Thanks

Why does this Visual Studio warning / problem occur?

I get this error whenever I want to access the database that I have created and it shows this message
Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed
Does anyone know how to solve this?

Execution group not starting Websphere message broker 8

We have Websphere Message Broker v8.0.0.3 on Redhat Linux env, and we encounterd the following runtime error message:
BIP2057
Execution Group <insert_1> could not be started: broker name <insert_2>; UUID <insert_3>; label <insert_4>; Pub-Sub server <insert_5> (1=Yes, 0=No).
The situation is that one of the execution groups stopped (without any trace/log about it) and the wmb could not auto start with the BIP2057 error.
the weird part occurs when another EG restarted (unlinked reason to the first problem, because of some applicative errors) and then the first EG "took its place", started successfully, and now the second EG could not start for the same reason.
We have checked for user permissions or the logs without any success in identifying the problem.
Any help would be much appreciated.
Run the following service IBM MQSeries if it's not running already:
C:\Program Files (x86)\IBM\WebSphere MQ\bin\amqlsvc.exe
If it gives an
exception of Access Denied, your user must not be having rights to
log on.
Another possible resolution can be by restarting the
DataFlowEngine.exe process.
If none of the above scenarios fulfill the need, restart the system.
