TIBCO® Managed File Transfer Platform Server for z/OS 8.1.0

# Defining Data Compression

You can use the COMPRESS parameter to specify whether to use data compression, or specify the compression algorithm used for a particular transfer request.

Note: For TIBCO MFT Platform Server for z/OS, you can only use Transfer Interface definition to specify the data compression algorithm used for a particular transfer request. The GLOBAL definitions do not supply a default compression type, but the NODE definition can define a default compression for transfers with that node.

You can implement data compression through the following user interfaces:

- Batch
- ISPF
- REXX

The format of the COMPRESS parameter is as follows:

    COMPRESS={YES | NO | RLE | LZ | ZLIB1 – ZLIB9}

The following table lists the description of each parameter option:

Option | Description
--- | ---
`YES` | The default compression algorithm (RLE) is used for this transfer.
`NO` | No compression is used for this transfer.
`RLE` | RLE compression is used for this transfer. Note: If you specify `YES`, RLE compression is used by default. For more information of RLE compression, see RLE Compression.
`LZ` | LZ compression is used for this transfer. For more information of LZ compression, see LZ Compression.
`ZLIB1` – `ZLIB9` | ZLIB compression is used for this transfer. For more information of ZLIB compression, see ZLIB Compression.
