Using the Standalone Batch Compression Utility

Before you begin

To invoke the standalone batch compression utility (cdsacomp), type the following command at a UNIX prompt:

cdsacomp

Following are the parameters for the cdsacomp utility:

Parameter	Description	Values

-m	Specify which mode to use: precompress	compress decompress
	or decompress. This argument is	The default is compress.
	required.	The default is compress.

-i	Specify the input file to precompress or	full or relative path of input file
	decompress. This argument is required.

-o	Specify the output file to save. If the	full or relative path of output
	output file already exists, it is	file
	overwritten. This argument is required.

-z	Use this option with “-m compress” to	level, window, memory
	override default compression values. This	level—Compression level.
	argument is optional.	level—Compression level.
		The range is 1–9. The default
	When decompressing, the values used	is 1.
	during compression are used.	1—Provides the least
		1—Provides the least
		compression, but is the
		fastest.
		9—Provides the most
		compression, but is the
		slowest.
		window—The size of the
		compression window and
		history buffer. Increasing the
		window increases the
		compression, but uses more
		virtual memory. The range is
		9–15. The default is 13.
		memory—The amount of
		virtual memory to allocate.
		The range is 1–9. The default
		is 4.
		1—Uses the least virtual
		memory.
		9—Uses the most virtual
		memory.

-x	Use this option to translate the file.	full path to translate table file
	If this parameter is not specified, the file	relative path to translate
	If this parameter is not specified, the file	table file
	is not translated.
	This parameter is mutually exclusive
	with -codepage.
