farm – Access denied to Service Applications page in Central Administration

I have farm admin permissions to a dev farm of on premises SP 2019 installation. The problem is that while I can access most of the features of Central Administration, whenever I access the Manage Service Applications feature (/_admin/ServiceApplications.aspx), I’m getting Access Denied message. Any idea what that might be?

Server Error in "" Application.

Access is denied. 
  Description: An error occurred while accessing the resources required to serve this request. The server may not be configured for access to the requested URL. 

 Error message 401.2.: Unauthorized: Logon failed due to server configuration.  Verify that you have permission to view this directory or page based on the credentials you supplied and the authentication methods enabled on the Web server.  Contact the Web server's administrator for additional assistance.

clustering – Mariadb galera cluster master node started and reporting 2 nodes but second node service says activating mariadb

I managed to start the master node mariadb galera cluster, then I started the second node and I check on the first master node;

$ sudo mysql -u root -p -e "SHOW STATUS LIKE 'wsrep_cluster_size'"
Enter password: 
| Variable_name      | Value |
| wsrep_cluster_size | 2     |

but when I checked the second node it says:

c# – How to create controller and service dynamically during runtime (inspired by directus)?

I would like to have a c# system that can

Create a table in the database during runtime

  1. On a webpage a user can create a object (for example TodoItem) and
    add fields for this object (Responsible, dueDate, enumerations
    (isDone, isOpen, isInProgress)).
  2. The webpage shall post all these as a string to the server and the server should create a table with
    matching columns.

Provide new Webservices during runtime

After the table is created the system should provide services / controllers to

  1. get a list of objects (the created TodoItem)
  2. View a single object (one TodoItem)
  3. Edit and Update an object
  4. Delete an object

Directus is a basic hybrid CMS and end user friendly databbase gui (similar to phpmyadmin) which offers these features. Directus is written in typescript (v9). php currently only v8 (v9 shall come later).

My problem is

  1. Which c# Query Builder is able to parse a string to SQL data definition language (like create a table, alter table and drop table). I found sqlkata but it seems that it does not provide SQL DDL functions.

  2. In c# how can services, classes and controllers be created during runtime?

    Why images uploaded on service are dead?

    Who use service ?
    I found that making description of my work less 2 years ago , among 4 links

    only 2 are available, but 2 are dead.

    I wrote to official support and got answer:
    Thanks for writing, I’m sorry to hear you’ve mistakenly deleted some images.

    Unfortunately, it’s not possible to restore deleted images once they have been removed. You can re-upload them, but you’ll be given a new link and the view count will reset.

    I apologize for the inconvenience caused by this.

    To reload them I need to review all my priorly works and reload images again – a lot of work.

    Are there some other similar services which DO NOT DELETE uploaded images?

    From personal expierence, please.

    VirtualBox Kernel Service Is Not Running

    I am using oracle virtualbox. I have installed the Virtualbox as well as Guest Additionls and built oracle linux VM. However, after I restarted the system, I got an error after successful reboot “notification in the linux VM to be precise” that says “Virtualbox Kernel service is not running”. I checked the log /var/log/vboxadd-setup.log and it said “restart guest or host”. I did restarted both but the issue persists. I don’t know where to start to investigate. Please assist.
