.SH "DESCRIPTION"
.PP
\fBmysql_upgrade\fR
examines all tables in all databases for incompatibilities with the current version of the MariaDB Server\&.
\fBmysql_upgrade\fR
also upgrades the system tables so that you can take advantage of new privileges or capabilities that might have been added\&.
.PP
\fBmysql_upgrade\fR
should be executed each time you upgrade MariaDB\&.
.PP
If a table is found to have a possible incompatibility,
\fBmysql_upgrade\fR
performs a table check\&. If any problems are found, a table repair is attempted\&.

On Windows Server 2008 and Windows Vista, you must run
\fBmysql_upgrade\fR
with administrator privileges\&. You can do this by running a Command Prompt as Administrator and running the command\&. Failure to do so may result in the upgrade failing to execute correctly\&.

To use
\fBmysql_upgrade\fR, make sure that the server is running, and then invoke it like this:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysql_upgrade [\fR\fB\fIoptions\fR\fR\fB]\fR
.fi
.if n \{\
.RE
.\}
.PP
After running
\fBmysql_upgrade\fR, stop the server and restart it so that any changes made to the system tables take effect\&.
.PP
\fBmysql_upgrade\fR
executes the following commands to check and repair tables and to upgrade the system tables:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlcheck \-\-all\-databases \-\-check\-upgrade \-\-auto\-repair
mysql < \fIfix_priv_tables\fR
mysqlcheck \-\-all\-databases \-\-check\-upgrade \-\-fix\-db\-names \-\-fix\-table\-names
.fi
.if n \{\
.RE
.\}
.PP
Notes about the preceding commands:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
Because
\fBmysql_upgrade\fR
invokes
\fBmysqlcheck\fR
with the
\fB\-\-all\-databases\fR
option, it processes all tables in all databases, which might take a long time to complete\&. Each table is locked and therefore unavailable to other sessions while it is being processed\&. Check and repair operations can be time\-consuming, particularly for large tables\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}

\fB\-\-check\-upgrade\fR
option entails, see the description of the
FOR UPGRADE
option of the
CHECK TABLE
statement\&.

\h'-04'\(bu\h'+03'\c

.el \{\

\fIfix_priv_tables\fR
represents a script generated internally by
\fBmysql_upgrade\fR
that contains SQL statements to upgrade the tables in the
mysql
database\&.
.RE
.PP
All checked and repaired tables are marked with the current MariaDB version number\&. This ensures that next time you run
\fBmysql_upgrade\fR
with the same version of the server, it can tell whether there is any need to check or repair the table again\&.
.\" mysql_upgrade_info file: mysql_upgrade
.\" mysql_upgrade: mysql_upgrade_info file
.PP
\fBmysql_upgrade\fR
also saves the MariaDB version number in a file named
mysql_upgrade_info
in the data directory\&. This is used to quickly check whether all tables have been checked for this release so that table\-checking can be skipped\&. To ignore this file and perform the check regardless, use the
\fB\-\-force\fR
option\&.
.PP
For this reason, \fBmysql_upgrade\fR needs to be run as a user with write access to the data directory\&.
.PP
If you install MariaDB from RPM packages on Linux, you must install the server and client RPMs\&.
\fBmysql_upgrade\fR
is included in the server RPM but requires the client RPM because the latter includes
\fBmysqlcheck\fR\&.
.PP
.PP
\fBmysql_upgrade\fR
supports the following options, which can be specified on the command line or in the
[mysql_upgrade]
and
[client]
option file groups\&. Other options are passed to
\fBmysqlcheck\fR\&. For example, it might be necessary to specify the
\fB\-\-password[=\fR\fB\fIpassword\fR\fR\fB]\fR
option\&.
\fBmysql_upgrade\fR
also supports the options for processing option files\&.
