{{usefulnote}}
== Database variables ==
{{Note box|See following wiki pages for the syntax of access to the configuration database entries from the command line [http://wiki.contribs.org/SME_Server:Documentation:Developers_Manual:Section2#Access_from_the_command_line Access from the Command Line] and a [http://wiki.contribs.org/Db_command_tutorial db command tutorial]}}
SME Server comes with the most used parameters set as variables in its internal configuration databases. These variables are used to store values to be used in the final configuration files. Please, read the [[SME_Server:Documentation:Developers_Manual:Section2]] to understand the template and database process.
These variables are useful to configure your system more easily, as you do not need to modify configuration files directly for most common cases. It also makes it possible to administer the server through its server-manager as the database variables are used to set and change configuration parameters. After editing, the configuration files must be regenerated and affected services need to be restarted.
For example, suppose you need to increase "memory-limit" in php.
You would simply execute these commands at the server console:
db configuration setprop php MemoryLimit 64M
expand-template /etc/php.ini
/etc/init.d/httpd-e-smith restart
The first line changes the value for the memory limit of PHP, the second line regenerates the configuration file and the last line will reload Apache (and subsequently also PHP as this is configured as a module of Apache).
{{Warning box|Database parameters are case sensitive so take great care when typing at the server shell because no error messages are given should you make a typo.}}
The database system is based on a flat file system, but you should never edit them directly. Instead you should use the db command. More details on using the database system can be found in the [http://mirror.contribs.org/smeserver/contribs/gordonr/devguide/html/devguide.html#SME-INTERNALS SME Server Developer's Guide].
=== Setting db variables to default values ===
{{Note box| Use of 'config' is a shorthand version for 'db configuration' and therefore only works with the configuration database}}
Any db variable that has a default value can be reset to the default by deleting the variable entirely, then re-initializing the default database values as follows:
config delprop <key> <prop>
/etc/e-smith/events/actions/initialize-default-databases
==== Delete a property value ====
To delete the property
db accounts delprop <key> <prop>
==== Reset a property value ====
To reset to an empty value
db accounts setprop <key> <prop> <nowiki>''</nowiki>
{{Warning box|Database parameters are case sensitive so take great care when typing at the server shell because no error messages are given should you make a mistake.}}
===Concept of the signal-event command===
Due to the efforts of the developers, you can further simplify the commands using the signal-event proccess.
For full details see [[SME_Server:Documentation:Developers_Manual:Section2]]
=== Overview of database variables ===
The next section describes the standard variables defined on SME Server. Please update this list with new standard variables in future SME Server versions.
The tables below have three columns. The first is the variable, the second is the target variable (located in the final configuration file), and the third is the default value.
A lot of the variables can be set using the server-manager but some can not. For example the variable DomainMaster for samba is not important here, because this can be set through server-manager. On the other hand, the variable RecycleBin is important, because it is not accessible through the server-manager.
The next is only the standard variables defined that come with SME7. Of course you can update this list with new standard variables in future SME versions.
Configuration files may use database values from a single configuration key, or may use multiple keys. The latter is the case for the /etc/rc.d/init.d/masq configuration file. This file takes it values from multiple database keys such as squid and masq.
It is also possible that multiple configuration files use the same key. An example of this is the httpd-admin key. This key has a variable TCPPort which is used in multiple files (/etc/httpd/admin-conf/httpd.conf and /etc/services).

{{Tip box|msg=You can see if you are running out of the number of available connections in your log file /var/log/dovecot/current (for sme8, it is /var/log/imap/current and /var/log/imaps/current) and look for messages like the log extract below where the ConcurrencyLimitPerIP was set to 12. A 13th connection was attempted and was denied.
@400000005396a2d215b40d9c imap-login: Info: Maximum number of connections from user+IP exceeded (mail_max_userip_connections=12):

}}
{{Tip box|Mobile devices have a tendency to frequently disconnect and connect from the network. When this disconnect happens, the sessions on the server are not always immediately cleaned up (they get cleaned up after a time out of some minutes). When the email client reconnects, they create new network connections and you get into the situation that these new connections get denied because of the concurrency limit. On the mobile device this may be noted as a "Unable to connect to server" message.
}}
{{Tip box|Some email clients use a separate connection per imap folder, so the concurrency limits may occur for users that have many imap folders.

==== Dovecot ====
* Only for SME Server 9

imap and imaps are used to be backward compatible with e-smith-imap (and are used to control the TCPPort of the service, and if it's accessible from local network or from the internet)<br />
dovecot is now the main service entry in the configuration DB. It's used to control various optional features of dovecot

=====Additional information on customizing iptables=====
Create a custom-named service definition in the configuration database.
db configuration set <servicename> service
Apply your desired firewall restrictions to any existing SME 'service' or to a custom-named service that you have created. Combine a custom-named service with port-forwarding to create customized firewall rules.
db configuration setprop <servicename> TCPPort <portnumber>
db configuration setprop <servicename> TCPPorts <portnumbers>
db configuration setprop <servicename> UDPPort <portnumber>
db configuration setprop <servicename> UDPPorts <portnumbers>

=====SupportLargeDrift=====
A new db key for ntpd: SupportLargeDrift.
Default value is disabled, which doesn't change the current behaviour. [[bugzilla: 7979]]
If set to enabled, it will
- add tinker panic 0 at the begening of the ntp.conf
- remove the lines
server 127.127.1.0 # local clock
fudge 127.127.1.0 stratum 10
With SupportLargeDrift enabled, the guest is able to resync the clock with the
configured ntp server, even after resuming from a suspended state (tested with
a ~10min drift, it took about 3 or 4 minutes for the guest to resync the clock
after resuming).
