System administration

System check

Settings -> Tools -> System check

The System check form helps to thoroughly examine the parameters compliance of system on which Bitrix Framework runs.

The form displays information grouped in the following sections.

• Required parameters - shows parameters that are critical for proper functioning of Bitrix Site Manager.
• Access check - displays results of checking the file system objects for reading and writing.
• Recommended settings - contains missing parameters which are not critical for the system operation, but you should set them to recommended values if possible.
• Modules - lists installed modules, or modules that can be installed.
• Technical support - you can use this mini-form to quickly send a request to the Bitrix helpdesk. Describe the problem in detail in the text input field, and type your e-mail address.

  Most problems can be solved faster if the message contains information about the system kernel and the PHP extensions, which can be obtained via calling phpinfo(). You are strongly recommended to leave the option Attach phpinfo() return to message enabled.

File check

Settings -> Tools -> File checker

The File check form helps administrators control changes in the system files. Here an administrator can enter a check word (in fact, the word is a password which is known to the administrator only) and calculate the checksum of all files of the site. The checksum depends on the password. The password is not stored anywhere.

The check result file contains information on each file checksum and status. Store the file on your local computer to prevent its loss. In future, you can always perform the check again using the same check word and compare results.

PHP Settings

Settings -> Tools -> PHP Settings

This form displays the current PHP settings obtained by calling phpinfo().

SQL Query

Settings -> Tools -> SQL Query

You can use the SQL Query form to execute an arbitrary SQL command.

PHP Command Line

This form (Settings > Tools > PHP Command Line) can be used to run a PHP script on the server side.

Agents

Settings -> Tools -> Agents

The Agents technology allows running PHP functions (agents) at a specified time interval. When a page starts execution, the system automatically checks for pending agents and executes them if required.

The report displays agents that currently exist in the system:

To add a new agent, click Add on the toolbar.

Backup

Settings -> Tools -> Backup

To help developers move their sites between servers, the system offers a special facility allowing to create back-up copies of the site. It can:

• create back-up copy of all files (tar.gz);
• exclude kernel folders;
• exclude files exceeding the specified limit;
• export (dump) database tables (tar.gz);
• exclude statistics and the search index from the dump.

All created files can be downloaded from the site and used on the other server.

To extract files from the archive, you will use the special script which is uploaded to the server with the archive.

Database check

If you encounter errors with MySQL /MyISAM tables, you can use the built-in database tool to check and repair tables.
