-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-This command must be run before any other process can access the
-overview database. It performs the following steps:
-.IP "1" 4
-.IX Item "1"
-Creates the database environment, if necessary
-.IP "2" 4
-.IX Item "2"
-If the database is idle (and if the \f(CW\*(C`\-u\*(C'\fR 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.
-.IP "3" 4
-.IX Item "3"
-If the \f(CW\*(C`\-u\*(C'\fR option is specified, it performs any necessary upgrades
-to the database. See the \s-1UPGRADING\s0 section below.
-.IP "4" 4
-.IX Item "4"
-Starts the \s-1DB\s0 housekeeping processes (ovdb_monitor) if they're not
-already running. (Unless the \f(CW\*(C`\-r\*(C'\fR option is specified).
-.IP "5" 4
-.IX Item "5"
-Starts the ovdb readserver (ovdb_server) processes if \f(CW\*(C`readserver\*(C'\fR
-in \fIovdb.conf\fR is \f(CW\*(C`true\*(C'\fR, and if they're not
-already running. (Unless the \f(CW\*(C`\-r\*(C'\fR option is specified).
-.PP
-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.
-.PP
-If a recovery was attempted but it failed, the database may be
-damaged beyond repair, requiring a rebuild with \fImakehistory\fR\|(8).
-.PP
-This command is normally invoked automatically by \fIrc.news\fR\|(8).
-.PP
-It is \s-1OK\s0 to run this command multiple times.

-Perform recovery only. \f(CW\*(C`ovdb_monitor\*(C'\fR is not started.
-.ie n .IP """\-u""" 4
-.el .IP "\f(CW\-u\fR" 4
-.IX Item "-u"
-Perform any needed upgrades. Recovery is not attempted.
-\&\f(CW\*(C`ovdb_monitor\*(C'\fR is started if the upgrade succeeded.
-.SH "UPGRADING"
-.IX Header "UPGRADING"
-There are two situations in which the database will need to be
-upgraded:
-.IP "\(bu" 4
-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\->\fIupgrade()\fR
-method is used.
-.IP "\(bu" 4
-You upgrade ovdb to a newer major version; i.e., ovdb\-1.0 to ovdb\-2.0.
-.PP
-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.
-.PP
-Here's an example procedure to upgrade a database created with BerkeleyDB
-2.7.7 to use BerkeleyDB 3.1.17:
-.IP "1" 4
-.IX Item "1"
-Build and install the BerkeleyDB 3.1.17
-.IP "2" 4
-.IX Item "2"
-Run configure in the \s-1INN\s0 source tree and make sure it picks up the
-right BerkeleyDB directory (e.g., /usr/local/BerkeleyDB.3.1)
-.IP "3" 4
-.IX Item "3"
-Do a \f(CW\*(C`make\*(C'\fR
-.IP "4" 4
-.IX Item "4"
-Shut down \s-1INN\s0 (e.g., with \f(CW\*(C`rc.news stop\*(C'\fR). Be sure to kill all nnrpds as
-well.
-.IP "5" 4
-.IX Item "5"
-Do a \f(CW\*(C`make update\*(C'\fR to install the new binaries.
-.IP "6" 4
-.IX Item "6"
-Run \f(CW\*(C`ovdb_init \-u\*(C'\fR as the news user.
-.IP "7" 4
-.IX Item "7"
-Start \s-1INN\s0 with \f(CW\*(C`rc.news\*(C'\fR
-.PP
-It is \s-1OK\s0 to specify \f(CW\*(C`\-u\*(C'\fR even if no upgrades are needed.
