NAME

       ovdb_init - Prepare ovdb database for use

SYNOPSYS

       ovdb_init ["-u"|"-r"]

DESCRIPTION

       This command must be run before any other process can access the
       overview database.  It performs the following steps:

       1   Creates the database environment, if necessary

       2   If the database is idle (and if the "-u" option is not specified),
           it performs a normal recovery.  The recovery will remove stale
           locks, recreate the memory pool cache, and repair any damage caused
           by a system crash or improper shutdown.

       3   If the "-u" option is specified, it performs any necessary upgrades
           to the database.  See the UPGRADING section below.

       4   Starts the DB housekeeping processes (ovdb_monitor) if they’re not
           already running. (Unless the "-r" option is specified).

       5   Starts the ovdb readserver (ovdb_server) processes if "readserver"
           in ovdb.conf is "true", and if they’re not already running. (Unless
           the "-r" option is specified).

       Returns exit status of 0 if all steps were completed successfully.  In
       the event of an error, messages are written to syslog and/or stderr.

       If a recovery was attempted but it failed, the database may be damaged
       beyond repair, requiring a rebuild with makehistory(8).

       This command is normally invoked automatically by rc.news(8).

       It is OK to run this command multiple times.

OPTIONS

       "-r"
           Perform recovery only.  "ovdb_monitor" is not started.

       "-u"
           Perform any needed upgrades.  Recovery is not attempted.
           "ovdb_monitor" is started if the upgrade succeeded.

UPGRADING

       There are two situations in which the database will need to be
       upgraded:

       ·   You upgrade the BerkeleyDB library to a newer version, for example
           from 2.7.7 to 3.1.17.  In this case, the BerkeleyDB db->upgrade()
           method is used.

       ·   You upgrade ovdb to a newer major version; i.e., ovdb-1.0 to
           ovdb-2.0.

       In both of these cases, the database is upgraded in-place; and the
       upgrade can not be undone.  Do not interrupt the upgrade process once
       it has started, because there is a risk of irrepairable corruption.
       The upgrade may take several minutes to complete.  If an upgrade does
       get interrupted, try running the upgrade again.

       Here’s an example procedure to upgrade a database created with
       BerkeleyDB 2.7.7 to use BerkeleyDB 3.1.17:

       1   Build and install the BerkeleyDB 3.1.17

       2   Run configure in the INN source tree and make sure it picks up the
           right BerkeleyDB directory (e.g., /usr/local/BerkeleyDB.3.1)

       3   Do a "make"

       4   Shut down INN (e.g., with "rc.news stop").  Be sure to kill all
           nnrpds as well.

       5   Do a "make update" to install the new binaries.

       6   Run "ovdb_init -u" as the news user.

       7   Start INN with "rc.news"

       It is OK to specify "-u" even if no upgrades are needed.
