Qu'est-ce qu'un fichier JOURNAL ?

A JOURNAL file is a system and service log created by Linux. It contains a record of system- and service-level kernel, boot, and component events. Administrators can use JOURNAL files to troubleshoot startup or service issues.

Plus d'informations

Many versions of Linux use a system management daemon named systemd. Systemd includes an event logging service named journald. This service regularly produces JOURNAL files.

Each JOURNAL file contains a log of system- and service-level events. This log can include kernel and boot events, syslog events, and service events. It is saved in a binary format.

Journald typically saves JOURNAL files in one of the following directories:

  • /​run/​log/​journal
  • /​var/​log/​journal

Active user-level JOURNAL files are named user-####.journal. Active system-level journal files are named system.journal. Archived JOURNAL files have similar filenames, but their filenames also include an @ and several letters and numbers.

Noms de fichiers .JOURNAL courants

System.journal - An active system-level JOURNAL file.

User-####.journal - An active user-level JOURNAL file.

Comment ouvrir un fichier JOURNAL

In a Linux system that uses systemd, you can use the journalctl command to view the entries a JOURNAL file contains. For example, you could use the command journalctl --file /path/to/your/journalfile.journal to view the log journalfile.journal contains.

A JOURNAL file is a record of the operations performed on a 4th Dimension database's data (.4DD file). For example, a JOURNAL file records changes, additions, and deletions made to its associated 4DD file. 4th Dimension creates JOURNAL files for each 4DD file by default.

Plus d'informations

4D 4th Dimension is a software development program that developers use to create desktop, web, and mobile applications. As part of creating these applications, developers construct and fill databases. Each database's structure is saved in a .4DB file; its data is saved in a 4DD file.

If an app development project has the Use Log option selected (as it is by default), 4th Dimension will also create a JOURNAL file for the app's database. The JOURNAL file contains a record of all the operations performed on a database's data since its last backup. This allows developers to troubleshoot problems with their databases and roll the database back to a previous post-backup state if necessary. When a developer backs up a database, 4th Dimension deletes the previous JOURNAL file and creates a new, blank JOURNAL file in which to begin recording new database changes.

Noms de fichiers .JOURNAL courants

Data.journal - The default name 4th Dimension assigns to JOURNAL files.

Comment ouvrir un fichier JOURNAL
