Full Discussion: Intimate Shared Memory (ISM)
Operating Systems Solaris Intimate Shared Memory (ISM) Post 302363363 by sprout009 on Tuesday 20th of October 2009 06:11:59 AM

Oops, my mistake.

I mean parameter _SHM_USE_ISM in /etc/system for Solaris, and parameter USE_ISM on initSID.ora for Oracle.

You're right, I have Oracle 10g on Solaris machine. I didn't find those parameters on both file system so I assume the ISM feature is ON.

What I know is that ISM doesn't support paging to disk. And I read that Oracle 9i supports DISM which supports paging to disk. So I'm wondering how to ensure whether my Oracle uses DISM feature or not. Do you know how to check this?

If my Oracle not in dynamic mode, since I have a limited resource of physical RAM, I'm afraid that this will cause system hang when simultaneous update executed. Your advice will be helpful. Thanks.

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
