The commit or rollback here indicates how you want MySQL to handle these unfinished transactions. If you think the transaction should be committed, use commit; if you think the transaction should be rolled back, use rollback.
commit
/etc/init.d/mysqld start --tc-heuristic-recover=commit
or
rollback
/etc/init.d/mysqld start --tc-heuristic-recover=rollback
