This parameter specifies whether CA XCOM Data Transport compresses the data being transferred and decompresses it on the remote system. Compressing the data decreases the transmission time on lower‑speed links.
Provides Run‑Length Encoding (RLE) for blanks and binary zeros only. YES is the default.
No data compression.
Provides complete Run‑Length Encoding for all characters.
Provides full RLE (as in RLE) plus a byte compaction scheme that is suitable for uppercase English text.
Same as COMPACT, only the compaction scheme is most beneficial for lowercase English text.
CA XCOM Data Transport compresses the data according to the small memory model of Lempel‑Ziv 77 compression.
CA XCOM Data Transport compresses the data according to the medium memory model of Lempel‑Ziv 77 compression.
CA XCOM Data Transport compresses the data according to the large memory model of Lempel‑Ziv 77 compression.
Greater compression than RLE but not as much as the Lempel‑Ziv 77 modes.
General‑purpose algorithm that runs fast and gives reasonable compression.
Greater compression than LZRW3 but less than LZSMALL, LZMEDIUM, and LZLARGE. The n value can be 1 through 9.
Note: Specifying a value other than NO enables use of zIIP to perform the compression function. zIIP processing is used for compression only if the buffer size to compress is >= 4096 bytes. Specifying PACK=LENGTH and use a high MAXPACK value (>= 4096) for TCP/IP transfers or RUSIZE (>=4096) for SNA transfers to make efficient use of zIIP.
Default: YES
This parameter specifies whether an existing data set is deleted and a new data set allocated at the start of a FILEOPT=CREATE transfer.
If FILEOPT=CREATE and the data set exists, then the transfer fail with a catalog/file error.
If FILEOPT=CREATE and the data set exists, then it is deleted and a new data set is allocated at the start of the transfer.
Default: NO
