This tool reads an +InnoDB +tablespace file, calculates the checksum for each page, compares the calculated checksum to the stored checksum, and reports mismatches, which indicate damaged pages\&. It was originally developed to speed up verifying the integrity of tablespace files after power outages but can also be used after file copies\&. Because checksum mismatches will cause +InnoDB +to deliberately shut down a running server, it can be preferable to use this tool rather than waiting for a server in production usage to encounter the damaged pages\&. +.PP +\fBinnochecksum\fR +cannot be used on tablespace files that the server already has open\&. For such files, you should use +CHECK TABLE +to check tables within the tablespace\&. +.PP +If checksum mismatches are found, you would normally restore the tablespace from backup or start the server and attempt to use +\fBmysqldump\fR +to make a backup of the tables within the tablespace\&. +.PP +Invoke +\fBinnochecksum\fR +like this: +.sp +.if n \{\ +.RS 4 +.\} +.nf +shell> \fBinnochecksum [\fR\fB\fIoptions\fR\fR\fB] \fR\fB\fIfile_name\fR\fR +.fi +.if n \{\ +.RE +.\} +.PP +\fBinnochecksum\fR +supports the following options\&.
