networking – Unstable wifi connection on Wireless 8260

I have tried

1.

sudo -i
echo "options rtl8723be fwlps=0"  >  /etc/modprobe.d/rtl8723be.conf
modprobe -r rtl8723be
modprobe rtl8723be
exit
  1. Ignore IPv6

  2. change REGDOMAIN in crda

  3. editing /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf and changed the value from 3 to 2, saved changes and rebooted.

yet my connection is still very unstable, I can get 50mb/s down sometimes (good speed for my internet plan) but sometimes it doesn’t even load webpages and chrome gives me a no internet detected on webpages, it can alternate between the 2 in the span of 30 mins.

Does Find my device feature require internet connection?

I lost my phone in the house, and I was trying out this feature but couldn’t connect to my phone. Why? Does it require Internet connection? If so, this feature doesn’t make much sense…

windows subsystem for linux – WSL2 Ubuntu 20.04 LTS GUI and Remote connection timeout issue

First of all, i am totally new in Linux and don’t got much experience in technology as a backround. However, i got some spark to this topic and decided to install Ubuntu 20.04 via WSL2. Everything went well, i can run Ubuntu GUI and Windows parallel etc after i have done “Remote desktop connection.”

BUT when i am having a smoke or idle for like 10min, the “remote desktop connection” is blank. To get back, i need to open terminal and use command sudo /etc/init.d/xrdp start and after that i can again use GUI.

The reason why i want to have both Windows and Ubuntu parallel at same time is that i need to work in Windows environment (my real job) but want to practice Ubuntu at same time.

Hope understood my problem and why it would be nice to be solved. Thanks in advance!

oracle – Application connection pooling load balancing the transactions on 18c RAC

Application connecting a 2 node 18c RAC.
JVMs are using connection pool and transactions are routed to the nodes via the connections in the pool. So the initial load across the nodes are distributed by SCAN listener. But the question is how does the existing connections in the pool distributes the next slot of transactions evenly across the 2 nodes, so that they are equally balanced.

sql server 2016 – Does SQLLocalDB ever require an internet connection?

Does SQLLocalDB ever require an internet connection?

I have seem some very strange behavior on an end user PC. The computer is normally offline (and user wants it to be for security). They have small local databases and use SQLLocalDB to access them. Version is 13.1.4001.0

Normally everything works fine. User can connect to existing databases and create new ones. Every few weeks, SQLLocalDB hangs and timeout on creating a new database. Connecting the PC to the internet and then disconnecting it (and doing nothing else) fixes the issue for another few weeks.

I can’t find any mention in online documentation of this requirement. Is there a way to disable this connection requirement?

Background: We are using C# Framework 4.6.2 code to connect and use the database.

/// This line works
// 'Server' is Microsoft.SqlServer.Management.Smo.Server
var server = new Server("(localdb)myserverinstancename");

/// this line works 99% of the time, but sometimes timesout and throws 
///"Microsoft.SqlServer.Management.Common.ConnectionFailureException: Failed to connect to server"
server.ConnectionContext.ExecuteNonQuery(databaseCreationScript);

php – Error: Lost connection to MySQL en Servidor

Tengo un problema con una consulta a mysql en php, estoy intentando ejecutar una consulta desde php a mysql en mi servidor, es una consulta simple, es un “DELETE FROM temp_sku”, estoy intentando ejecutar esta consulta con un procedimiento almacenado pero me da el siguiente error:

Uncaught PDOException: SQLSTATE(HY000): General error: 2013 Lost
connection to MySQL server during query

Entiendo que este error es como si se superara el tiempo de conexión o algo similar, el problema es que este DELETE realmente no pesa nada solo es una tabla con una sola columna que almacena sku’s por lo cual no pesa en absoluto.

Mi conexión la creo de la siguiente forma:

try{
            $connect = new PDO("mysql:host=".DB_HOST.";dbname=".DB_NAME,DB_USERNAME, DB_PASSWORD,
            array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES 'utf8'"));
            $connect->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        } catch (PDOException $e){
            $error = $e->getMessage();
            exit("Error: " . $e->getMessage());
        }

he intentado cambiar mi consulta y no usar un procedimiento almacenado, la he cambiado a esta forma:

$stmt = $connect->prepare("DELETE FROM temp_sku");
$stmt->execute();

Pero sigo recibiendo el mismo error. No entiendo que puedo estar haciendo mal.
