Description

The DATA_COMPRESSION option specifies whether or not data standard I/O file transmissions across the network should be compressed.

Optionally, it also can specify the compression method to use.

Usage

Values

option is either of the following values:

• yes
  Data compression is required. All data in standard I/O file transmissions is compressed regardless of the UCMD Manager DATA_COMPRESSION option value.
• no
  Data compression is not required. However, data compression still can be requested via the UCMD Manager DATA_COMPRESSION option.

Default = no.

method is either of the following values:

• zlib
  Data is compressed using ZLIB compression algorithm. This method usually results in a very high compression rate, but tends to be somewhat CPU-intensive. It is recommended in environments where controlling a process's CPU usage is not necessarily a priority.
• hasp
  Data is compressed using the HASP compression algorithm. This method is less CPU-intensive than the ZLIB method. It is recommended in environments where controlling CPU usage is a priority. With HASP, the compression rate, while still very good, tends to be a little less than what is possible with the ZLIB.

Default is zlib.
