There are various causes of corruption, such as file overwrite issues, file locking issues, database synchronization failures, storage media failures, and many more. If the SQLite database is corrupted, it needs repair.

Prevention Checklist to Fix SQLite Unable to Open Database Issue

Prevention of the SQLite database is always better than repairing. First, try to attempt the following checklist to fix the database inaccessible issue:

  • Make sure Apache can write to the database’s parent directory.
  • Make sure that the folder does not start with the full path to the database files with a number.
  • Check the full path containing the db directory.
  • Make sure that the /tmp directory is globally writable.
  • Make sure that the path to the database specified in settings.py is a complete path.
  • Make sure there are no special characters in the path.
  • On Windows, make sure the db directory path is written with double backslash.

Common Causes of SQLite Database Inaccessible Issue

When SQLite database is corrupted, it becomes inaccessible at any time. Before explaining how to repair SQLite database, let’s discuss the most common causes of SQLite database file corruption.

1. The Problem of Overwriting
You can overwrite the SQLite database file because it is a regular disk file. There is no way to protect your SQLite database from such overwrites. There can be some serious problems, including Running file descriptor, Restoration while a transaction is in running mode and Deletion of a Hot journal.

2. File Locking Problem
SQLite provides the ability to lock SQLite database files. Unnecessary changes caused by two different processes to the SQLite database can result in data corruption. To avoid this, only lock the SQLite database. On the other hand, if the function is convenient for the user, it can cause serious problems. These are Missing lock details, POSIX advisory lock cancellation, The contradiction of two different protocols, Numerous links to a file and Rename or unlink database.

3. Database Synchronization Failure
SQLite database sync command operates real sync. That’s what causes the SQLite unable to open database file error. But if it acts as an I / O barrier, you may face obstacles that will allow you to roll back the action further. This puts the SQLite database in passive mode as it can override ACID properties (Atomicity, Consistency, Isolation, Durability).

4. Storage Media Failure
If something goes wrong with your storage media devices, such as your system’s hard disk or flash memory, the SQLite database can be corrupted. Unsolicited changes to the content of the storage media can cause serious problems for SQLite users. Make sure you have enough storage space on the disk so you can write more details. However, if you do not have space to store data and try to write something to it, your SQLite database may be corrupted.
