Fix a corrupt WSL database

Fix a corrupt WSL database

In this article we describe how to fix a corrupt WebSolarLog SQLite database.
This guide is only for SQLite databases, please see your Admin::Diagnostics to see on which database type your WebSolarLog is running.

First WE NEED TO MAKE a BACKUP of the database

Go to the WebSolarLog/database directory on your server/host

Stop WSL;
WebSolarLog/scripts/ stop
Creat backup of wsl.sdb;
cp wsl.sdb wsl_backup.sdb

Move the original database;
mv wsl.sdb wsl_original.sdb


Lets do it!

Assuming that you are still in the WebSolarLog/database/ directory, run the following commands;
sqlite3 wsl_backup.db

We first run the following integrity command to make sure the database needs some repairs. On the SQLite prompt you run:
pragma integrity_check;

If the result is OK, the database is not corrupted and needs no further actions.

you can quit SQLite by :

restore the old database;
mv wsl_original.sdb wsl.sdb

If you have error messages you could proceed to Next Steps.


Export Data to plaintext file

To export the WebSolarLog data to an plaintext sql file, run the following commands:

echo .dump | sqlite3 wsl_backup.sdb > wsl_plaintext.sql

Now we have a plaintext file with readable SQL data/commands. You could read the file;
nano wsl_plaintext.sql

Create a new WSL database

Now we have a plaintext file with the data, we need to create a new database

To create a new WSL database, just run the following command:

cat wsl_plaintext.sql | sqlite3 wsl.sdb

This command creates a new WSL database with the original data from the corrupt database.


We are Ready!

If there are no errors, then we could start WSL;

WebSolarLog/scripts/ start
