NAME

       ctl_conversationsdb - Cyrus IMAP documentation

       Perform operations on the conversations databases

SYNOPSIS

       ctl_conversationsdb [ -C config-file ] -d userid > text
       ctl_conversationsdb [ -C config-file ] -u userid < text
       ctl_conversationsdb [ -C config-file ] [ -v ] [ -z | -b | -R ] userid
       ctl_conversationsdb [ -C config-file ] [ -v ] [ -z | -b | -R ] -r

DESCRIPTION

       ctl_conversationsdb  is used to perform various administrative operations on a conversations database and
       associated information in cyrus.index files.

       ctl_conversationsdb 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
       conversations database.

       In the first synopsis, the -d option dumps the contents of a conversations database to standard output in
       an ASCII format.  In the second synopsis, the resulting file is fed back  in,  using  the  -u  option  to
       "undump" from standard input.  This pair of commands is useful for disaster recovery, or for changing the
       backend used to store the conversations database.

       The  third synopsis is used to reconstruct conversations information in various ways for a specific user,
       and the fourth to reconstruct conversations information for all users.  See OPTIONS below for details.

       This command was introduced in version 3.0.

OPTIONS

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

       -d userid
              Dump the conversations database which corresponds to the user userid  to  standard  output  in  an
              ASCII format.  The resulting file can be used to recreate a database using the -u option.

       -u userid
              "Undumps"  the  conversations  database  corresponding  to  the user userid, i.e. replaces all the
              entries with data from ASCII records parsed from standard input.  The output from  the  -d  option
              can be used as input.

       -v     Be more verbose when running.

       -r     Be  recursive;  apply  the main operation to every user.  Warning: do not combine with -u, it will
              not do what you expect.

       -z     Remove all conversation information from the conversations database for user userid, and from  all
              the  user's mailboxes.  The information can all be recalculated (eventually) from message headers,
              using the -b option.

       -b     Rebuild all conversation information in the conversations database for user userid, and in all the
              user's mailboxes, from the header information in messages.  Does not affect messages which already
              have conversation information.

              This is a bulk mode version of what happens to each message when it arrives, and can  be  used  to
              add  missing  conversation  information  for past messages, e.g. after using -z or after upgrading
              Cyrus from older versions.  Note: this operation uses information from  cyrus.cache  files  so  it
              does not need to read every single message file.

       -R     Recalculate  counts of messages stored in existing conversations in the conversations database for
              user userid.  This is a limited subset of -b; in particular it does not  create  conversations  or
              assign messages to conversations.
