What is the impact of starting Microsoft SharePoint Foundation Web Application Service in Application Server?

I have a SharePoint 2013 server farm with 4 SharePoint servers (2 web front end and 2 application servers) + 1 SQL server.

I have a custom SharePoint solution which can be deployed globally. When I deploy this solution using either Central Admin or STSADM.EXE or Powershell, I am seeing that the solution is being in “Deploying” state for some time and then it is changed to “Not Deployed” state.

When I open the solution from Central Administration, it says that solution is successfully deployed to 3 servers and fourth server (one of the application servers) is not listed there and there is no error message.

“Microsoft SharePoint Foundation Web Application” service is not running in both the Application Servers but the solution is being deployed to one of the application servers.

Can I start “Microsoft SharePoint Foundation Web Application” service in both the Application Servers? What is the impact of running this service in application servers?

or is there anything else that I can do without starting this service in application servers?

Thanks in Advance.

How is plaintext handled at protonmail server?

I am quite happy with, indeed grateful for, protonmail. There is one point I’d like to understand better regarding end-to-end encryption. I asked this twice at protonmail.com, and twice it was removed by the moderator. I hope someone here can answer.

I infer that an outgoing message is transmitted via https to the protonmail server where it is pgp-encrypted and the plaintext discarded; the reverse for incoming messages. Is this basically correct?

If so, then “end-to-end encryption” doesn’t mean quite what I thought, and I would like to know a little more about how the plaintext is handled by the server.

I don’t distrust protonmail. I understand that if I felt the need I could download public and private keys and encrypt locally, but then I might as well use gmail :p

Sql Server – Multiple errors regarding to memory in error log

MSSQL-Server 2017 Express Edition runs on my Linux server.
The server has 4GB RAM.
The total size of DB is 300MB.

My website and the sqlserver are on the same server, it’s a small website with max of 400-300 visitors a day. Memory usage in linux looks fine, mssql takes only 20% memory:

enter image description here

Some additional sql memory information:
enter image description here

Maximum server memory is set to 2147483647 which is the default I guess.

The errors I get:

enter image description here enter image description here

After restarting the mssql-service there are no problems for something like 2 days and then it repeats it self.

I would happily get an answer that will solve this for me, but I would also like to get a resource where I can learn about memory allocation/cache/pages/ related to sql server because I am not a sql expert, I am a programmer.

My root domain is not resolving to my server, but the www. subdomain works fine

I have the DNS configured like this:

enter image description here

So, my domain example.mx is working as http://www.example.mx. With www there is no problem, but with non-www like http://example.mx it’s not working.

As you can see, my DNS records are pointing in example.mx record to the NS ns1.example.mx. Actually, ns1.example.mx is pointing to my server’s IP.

What could be the problem which is causing http://example.mx not to work while http://www.example.mx does work?

You don’t have permission to access /Proyecto/CodeIgniter/application/controllers/articulos on this server

Me sale ese error cuando intento acceder. Ya arreglé algunas configuraciones que encontré en otras preguntas similares, pero me sigue saliendo lo mismo. Alguien podría ayudarme? el archivo .htacess ya lo modifiqué para que no fuera necesario usar index.php en mi archivo config.php de CI, tengo como Base_URL la carpeta “localhost:8888/Proyecto/CodeIgniter” pues ahí tengo almacenada la carpeta

¿Como eliminar las tablas que no le pertenezcan a una base de datos en un TreeView? c# Windows Forms, Microsoft SQL Server

Resulta que tengo un TreeView que me muestra todas las bases de datos que hay con sus respectivas tablas. El problema como verán es que me aparecen tablas a las que le pertenecen a una base de datos pero que tambien les aparecen en otras, lo cual está mal.

introducir la descripción de la imagen aquí

Y lo que quiero es que me muestren nomas las tablas a las que les pertenecen la base de datos únicamente.

       TreeNode node;     TreeNode hijo;     private void Form1_Load(object sender, EventArgs e)     {         DataTable tabla = new DataTable();         DataTable tablas = new DataTable();          ReglasDeNegocios.OperacionesBD operaciones = new ReglasDeNegocios.OperacionesBD();         if (operaciones.BaseDatos(sUsuario, sPassword, ref tabla))         {               foreach (DataRow dr in tabla.Rows)             {                 node = new TreeNode(dr["name"].ToString());                 string hijos = Convert.ToString(dr["name"].ToString());                 if (operaciones.BaseDatos(sUsuario, sPassword, hijos, ref tablas))                 {                     foreach (DataRow dr2 in tablas.Rows)                     {                          hijo = new TreeNode(dr2["Tabla"].ToString());                         node.Nodes.Add(hijo);                     }                     treeView1.Nodes.Add(node);                 }              }             }         else         {              MessageBox.Show("Ocurrio un error: " + operaciones.sLastError);         }     } 

Asi mando a llamar la BaseDatos:

  public Boolean BaseDatos(String sUsuario, String sPassword, String BD, ref DataTable Tabla)     {         Boolean bAllOk = false;         using (SqlConnection conexion = new SqlConnection())         {             try             {                  conexion.ConnectionString = $  "Server=ROBERTODIAZ; User Id={sUsuario}; Password={sPassword}";                 conexion.Open();                 SqlCommand comando = new SqlCommand($  "use {BD} select sc.name+'.'+tb.name AS Tabla from sys.tables tb inner join sys.schemas sc on tb.schema_id = sc.schema_id order by Tabla ASC", conexion);                 SqlDataAdapter adapter = new SqlDataAdapter(comando);                 adapter.Fill(Tabla);                   bAllOk = true;              }             catch (Exception ex)             {                 sLastError = ex.Message;             }             finally             {                 conexion.Close();             }         }         return bAllOk;     }

Add Failthrough server of a LAN IP to Nginx?

I’m trying to add my machine’s LAN IP as a ‘failthrough’ location to use in the event the main server has issues.

Lately, my main server name (i.e. https://myserver.domain.com) has been having some issues due to LetsEncrypt certs issues, so any URL running on my server using that domain name fails as well. What I want is to have Nginx automatically pass it to the machine’s IP instead if it detects the domain name itself is down.

I’m using the Docker LinuxServer LetsEncrypt container, and I’ve tried just adding the IP to the server_name variable in the config, but after restarting the container, nothing appears to change when trying to navigate to https://myserver.domain.com (it still just gives the same error page instead of redirecting to the IP).

Here’s the current config with the issue:

server {      listen 443 ssl http2 default_server;      root /config/www;     index index.php index.html index.htm;      server_name myserver.*;      # enable subfolder method reverse proxy confs     include /config/nginx/proxy-confs/*.subfolder.conf;      # Tell search engines not to crawl/add this domain     add_header X-Robots-Tag "noindex, nofollow, nosnippet, noarchive";      # all ssl related config moved to ssl.conf     include /config/nginx/ssl.conf;      # enable for ldap auth     #include /config/nginx/ldap.conf;      client_max_body_size 0;      location ~ \.php$   {         fastcgi_split_path_info ^(.+\.php)(/.+)$  ;         fastcgi_pass;         fastcgi_index index.php;         fastcgi_param  SCRIPT_FILENAME  $  document_root$  fastcgi_script_name;         include /etc/nginx/fastcgi_params;     } } 

Note this line in particular; the IP as the second server is the intended failthrough IP:

server_name myserver.*;

Also note: if I just use directly in a browser, it navigates to the intended page fine, so this has to be something config-wise with Nginx that I’m trying to solve. It seems like a pretty simple issue, but I’m not super familiar with Nginx config nuances yet.
