       This release note describes patch SG0002883 to IRIX 5.3.
       Patch SG0002883 replaces	patches	SG0000184 and SG0000505.

       1.1  Supported_Hardware_Platforms

       This patch contains bug fixes for all platforms.

       1.2  Supported_Software_Platforms

       This patch contains bug fixes for IRIX 5.3.  The	software
       cannot be installed on other configurations.

       1.3  Bugs_Fixed_by_Patch_SG0002883

       This patch contains fixes for the following bugs	in IRIX
       5.3.  Bug numbers from Silicon Graphics bug tracking system
       are included for	reference.

	  o When attempting to use various sccs	commands that
	    require file locking, the algorithm	used to	determine
	    if a file lock would be successful improperly evaluated
	    the	group inclusion	of the user.  This could
	    erroneously	result in the following	fatal error message
	    being issued by the	sccs command: "cannot create lock
	    file (cm4)".  (Bug #248619)

	  o The	file locking routines in the sccs commands work
	    improperly when used on machines with hostnames of
	    length greater than	9.  This will result in	either a
	    slow down or failure of the	"get -e" command.  (Bug
	    #242036)

	  o SCCS breaks	in 2000(Bug# 354663).

	  o Irix 6.2 'sccs' not	y2k compliant(Bug #543209).

       1.5  Installation_Instructions

       Because you want	to install only	the patches for	problems
       you have	encountered, patch software is not installed by
       default.	After reading the descriptions of the bugs fixed in
       this patch (see Section 1.3), determine the patches that

       meet your specific needs.

       If, after reading Sections 1.1 and 1.2 of these release
       notes, you are unsure whether your hardware and software
       meet the	requirements for installing a particular patch,	run
       inst.

       Patch software is installed like	any other Silicon Graphics
       software	product.  Follow the instructions in your Software
       Installation Administrator's Guide to bring up the miniroot
       form of the software installation tools.

       Follow these steps to select a patch for	installation:

	 1.  At	the Inst>prompt, type

	     install patchSGxxxxxxx

	     where xxxxxxx is the patch	number.

	 2.  Select the	desired	patches	for installation.

	 3.  Initiate the installation sequence. Type

	     Inst> go

	 4.  You may find that two patches have	been marked as
	     incompatible.  If this occurs, you	must deselect one
	     of	the patches.

	     Inst> keep	patchSGxxxxxxx

	     where xxxxxxx is the patch	number.

	 5.  After completing the installation process,	exit the
	     inst program by typing

	     Inst> quit


       To remove a patch, use the versions remove command as you
       would for any other software subsystem.	The removal process
       reinstates the original version of software unless you have
       specifically removed the	patch history from your	system.

       versions	remove patchSGxxxxxxx

       where xxxxxxx is	the patch number.

       To keep a patch but increase your disk space, use the
       versions	removehist command to remove the patch history.

       where xxxxxxx is	the patch number.
