Neelakanth Nadgir on MySQL and ZFS: A File System Revolution
A year ago this past week (on January 16, 2008), Sun Microsystems announced a historic deal to acquire MySQL AB for a billion dollars. Since then, MySQL-ers (aka Sun Dolphins) have settled in with Sun folks. While Sun has had an influence on MySQL, MySQL has also had an influence on several projects within "Sun Classic". Over this week, we hope to explore some of the projects around Sun which use MySQL and how the acquisition has helped bring us all closer together.Today we talk to Neelakanth Nadgir in the Sun/MySQL Performance Team about MySQL and ZFS, the revolutionary file system included with Solaris and OpenSolaris operating systems from Sun.

mysql_fix_extensions

MYSQL_FIX_EXTENSI(1)					       MySQL Database System					      MYSQL_FIX_EXTENSI(1)

NAME

       mysql_fix_extensions - normalize table file name extensions

SYNOPSIS

       mysql_fix_extensions data_dir

DESCRIPTION

       mysql_fix_extensions converts the extensions for MyISAM (or ISAM) table files to their canonical forms. It looks for files with extensions
       matching any lettercase variant of .frm, .myd, .myi, .isd, and .ism and renames them to have extensions of .frm, .MYD, .MYI, .ISD, and
       .ISM, respectively. This can be useful after transferring the files from a system with case-insensitive file names (such as Windows) to a
       system with case-sensitive file names.

       Invoke mysql_fix_extensions like this, where data_dir is the path name to the MySQL data directory.

	   shell> mysql_fix_extensions data_dir
