|
|
|
|
The following section is included to inform users about the potential risks,

|
|
tools) and those created by bugs.
|
|
|
|

|
if the file contains a PID and a process is running with that PID, then
|

the script dies; or, if there is no process running with that PID, then the

=head1 DSN OPTIONS
|
|
|
|
These DSN options are used to create a DSN. Each option is given like
|
|
C<option=value>. The options are case-sensitive, so P and p are not the
|
|
same option. There cannot be whitespace before or after the C<=> and
|
|
if the value contains whitespace it must be quoted. DSN options are
|
|
comma-separated. See the L<percona-toolkit> manpage for full details.
|
|
|
|
=over

|
|
=head1 ENVIRONMENT
|
|
|
|
The environment variable C<PTDEBUG> enables verbose debugging output to STDERR.
|
|
To enable debugging and capture all output to a file, run the tool like:
|
|
|
|
PTDEBUG=1 pt-agent ... > FILE 2>&1
|
|
|
|
Be careful: debugging output is voluminous and can generate several megabytes
|
|
of output.
|
|
|
|
=head1 SYSTEM REQUIREMENTS
|
|
|
|
You need Perl, DBI, DBD::mysql, and some core packages that ought to be
|
|
installed in any reasonably new version of Perl.
|
|
|
|
=head1 LIMITATIONS
|
|
|
|
=over
|
|
|
|
=item Replicas using row-based replication
|
|
|
|
pt-agent requires statement-based replication, and it sets
|
|
C<binlog_format=STATEMENT> on the master, but due to a MySQL limitation
|
|
replicas do not honor this change. Therefore, checksums will not replicate
|
|
past any replicas using row-based replication that are masters for
|
|
further replicas.
|
|
|
|
The tool automatically checks the C<binlog_format> on all servers.
|
|
See L<"--[no]check-binlog-format"> .
