**ctl_cyrusdb**
***************

Perform administrative operations directly on Cyrus IMAP databases.


Synopsis
========

   **ctl_cyrusdb** [ **-C** *config-file* ] **-c**
   **ctl_cyrusdb** [ **-C** *config-file* ] **-r** [ **-x** ]


Description
===========

**ctl_cyrusdb** is used to perform various administrative operations
on the Cyrus IMAP databases.

**ctl_cyrusdb** reads its configuration options out of the
imapd.conf(5) file unless specified otherwise by **-C**. The
*configdirectory* option in imapd.conf(5) is used to determine the
default location of the Cyrus databases.


Options
=======

-C config-file

   Use the specified configuration file *config-file* rather than the
   default imapd.conf(5).

-r

   Recover the database after an application or system failure. Also
   performs database cleanups like removing mailbox reservations (and
   the associated mailbox files).

   All mailbox files are also checked to make sure the file format
   matches the configured database type in imapd.conf.  If not, the
   file is automatically converted using the same logic as
   cvt_cyrusdb.

   If the "reverseacls" option in imapd.conf(5) is enabled, and the
   RACL entries in the database are an old version or do not exist,
   they will be generated.  Conversely, if RACL entries do exist in
   the database, but the "reverseacls" option is disabled, then the
   entries will be cleaned up.

-x

   Used with "-r" to only recover the database, and prevent any
   cleanup.

-c

   Checkpoint and archive (a copy of) the database.

   Changes to the database which are part of the committed
   transactions are written to disk.

   The archive is created via a *hot* backup, and inactive log files
   are removed.


Examples
========

   **ctl_cyrusdb -r**

   Recover databases, performing cleanup.  This is commonly used in
   the **START** section of cyrus.conf(5).

   **ctl_cyrusdb -x -r**

   Recover database only.

   **ctl_cyrusdb -c**

   Checkpoint databases.  Commonly used in the **EVENTS** section of
   cyrus.conf(5).


Files
=====

/etc/imapd.conf /etc/cyrus.conf
