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. |
