Maintenance

[domentarion]

Hello Guys,

I have a problem. I can't figure out how i most do something. I shall explain what is my problem

First i gonna tel you about my program :

I have a program that loads a splash screen. During the splashscreen the program do some validations :

1. Check if the computer has connected to the network
2. Check if the program has a configuration file(tekstfile)
3. Checks the configuration file is it has a databaseserver, databasename , username and password
4. Check is it can reach the databaseserver
5. Check is the database exists
6. Check if the username and password is correct

If something is wrong the program gives a specific message. Now i wanne add something that checks if there is a maintenance , but i don't hava any idea how i can do this ? Does somebody have a idea?

By maintenance do you mean a new version of the software?

Do you mean show a custom message when an error occurs?

I mean when i am working at my databaseserver then i want a specific message

You can create a table called "settings" and have a column "key" and "value".

When it connects, have it check the settings for a row "maintenance", if the "value" is set to true, then have the program spit out the error.

I mean that i have already error when the database is not reachable, but i want is something in the system when i working at my server or the server is down that the program knows when there is a maintenance at the server.

The problem with that is that the database also need to be online.

Hm, from what I understand you need to create a program or function that detects whether the server is online and then records the information to a file.

Theres pretty much no way I can think off that your program could distinguish between the database server being down for maintence and the database server crashing.

The possible options would likly involve storing the Maintence Flag somwhere externally from the database server.
