This section summarizes the changes made to the Entire Net-Work CTC Option in this release:
Effective with version 6.3 SP2, zEnterprise Data Compression (zEDC) is supported on z/OS systems. This support comes in the form of two new LINK parameters for both the CTCA and FCTC line drivers: ZEDC and ZEDCLOG. The ZEDC parameter indicates whether zEDC compression can occur for the link; the ZEDCLOG parameter identifies the level of trace data that should be logged for zEDC compression processing. For more information, read CTCA and FCTC LINK Statements.
The following table summarizes the new Entire Net-Work CTC Option DRIVER and LINK parameters introduced in Entire Net-Work 6.3:
| Parameter | DRIVER or LINK Statement? | New or Changed? | Description | Introduced in Release |
|---|---|---|---|---|
| ZEDC | LINK | New | This new parameter indicates whether zEnterprise Data Compression (zEDC) compression can occur for the link. | 6.3 SP2 |
| ZEDCLOG | LINK | New | This new parameter indicates what level of trace data will be logged for zEDC compression processing. | 6.3 SP2 |
The CTCA line driver supports connections with CTCA line drivers from all prior versions of Entire Net-Work.
As of version 6.3, the FCTC line driver is incompatible with
previous releases of FCTC. To address this, specifying COMPAT=Y
enables compatibility mode, which detects a connection to a prior version of
FCTC and automatically converts that connection to a compatible 6.2 SP2
connection.
For complete information about the COMPAT parameter, read FCTC Line Driver Compatibility and CTCA and FCTC DRIVER Statements.
