This document lists the Entire Net-Work 6.5 enhancements.
Enhancements have been made to the Adabas Directory Server (ADI) entries created by Entire Net-Work when ADI support is active. These include qualifiers that identify an ADATCP node, and a weight value. These parameters help the client application choose the best path to the database destination.
Support for Adabas Manager (AMN) has been enhanced, including the ability to display and modify Entire Net-Work parameters. For more information, see the section Adabas Manager in the Entire Net-Work Administration and the Adabas Manager documentation.
MLC Version 1.3.5 or above is now required. If an invalid version of MLC is used, the message NETL010E: Error using MLC version older than V135 is issued and Entire Net-Work terminates. See also Software AG Mainframe Product Licensing for further details.
The Encryption for Entire Net-Work (product code WSL) component of Entire Net-Work for z/OS is being discontinued. Encryption for Entire Net-Work Version 6.4.1 is the final release of Encryption for Entire Net-Work on z/OS.
The IBM product AT-TLS (Application Transparent-Transport Layer Security) is recommended as a replacement for Encryption for Entire Net-Work. AT-TLS is a component of the z/OS Communication Server and provides SSL/TLS connections directly in the z/OS TCP/IP stack. AT-TLS is compatible with Entire Net-Work TCP/IP connections and provides full SSL/TLS capabilities.
For more information on AT-TLS, see the IBM documents z/OS Communications Server: IP Configuration Guide and z/OS Communications Server: IP Configuration Reference.
For more information on AT-TLS usage with Entire Net-Work, see Using Encryption for Entire Net-Work.
If the release or SM level of the license (less than or greater than) does not match the level running, the message MLC2003 The product license is not for WCP 6.5.1 is issued, the license is accepted, and Entire Net-Work continues.
Usage of the Entire Net-Work TCP/IP Option component (TCPI, TCPX drivers) now requires an Entire Net-Work TCP/IP Option license. This license is made available to the session either in a load module named WTCLIC or a DD statement with DDNAME DDLWTC.
This does not apply to the products Entire Net-Work Administration (WCA) or Entire Net-Work Limited Load (WDX).
If running with Entire Net-Work Administration (WCA) or Entire Net-Work Limited Load (WDX), the MLC library is no longer required, unless running with zIIP, which still requires a zIIP license file.
With Entire Net-Work version 6.5 SP2, and in conjunction with Adabas SAF Security, the following security-related enhancements are now available:
Note:
The pre-requisites for providing this protection are:
Adabas version 8.5 SP2 or above
Adabas Limited Library (WAL) version 8.5 SP2 or above
Adabas SAF Security version 8.2 SP2 Patch level 2 or above
Entire Net-Work start-up can now be protected by defining appropriate resource profiles denoting Target ID and SVC number.
Refer to the Operations section of the Adabas SAF Security documentation for more information on this topic including the format of the resource names used.
Entire Net-Work administration functions can now be protected ensuring unauthorized use of such functions is not permitted.
For example, a user or group may be allowed to use the
DISPLAY command to display current information about
a network component but disallowed from using the
SET command to dynamically change parameter
settings.
Refer to the Operations section of the Adabas SAF Security documentation for more information on this topic including the list of applicable administration functions and the format of the resource names used.
This protection is available for operator commands issued from both the console and the Programmable Command Interface (PCI).
With Entire Net-Work version 6.5 SP2 the
REFRESH command is
introduced:
The REFRESH command updates Net-work's target table from the contents of the Adabas ID table on the same SVC as the Net-Work node. For more information see REFRESH Command in the section Operator Commands Summary.
Note:
The prerequisite for the usage of this operator command is
WM652011.
This release introduces support for the Adabas Directory Server (ADI). The ADI allows applications to determine the location of their Adabas target, allowing direct access to a database without the call traveling through intermediate Net-work kernels. ADI communication is handled by the TCPX driver.
See Adabas Directory Server Administration and TCPX DRIVER Statement for details.
Note:
Fix WT651005 is required for partition support.
This release introduces support for Adabas Manager (AMN). ADI support must be active in order for the AMN client to communicate with the Net-work or ADATCP kernel. Communication with AMN is handled by the TCPX driver.
See TCPX DRIVER Statement for details.
ADATCP is a subset of an Entire Net-Work kernel that runs as a subtask in an Adabas session. It provides direct communication with application programs, eliminating the need for intermediate Net-work kernels.
For direct communication with ADATCP, application programs running on Linux, UNIX or Windows platforms use Entire Net-Work Client (WCL). Mainframe application programs use a TCP/IP-enabled ADALNK, available starting with Adabas 8.5.1.
Using Point-to-point support for Adabas (ADATCP) requires Entire Net-Work Version 6.5 SP1 or above and Entire Net-Work TCP/IP Option Version 6.5 SP1 or above.
A valid Entire Net-Work license is now required for ADATCP in addition to any Adabas licenses. Because the Adabas nucleus and the ADATCP kernel can both read DDLIC to obtain their license, it is recommended that the Entire Net-Work license be assembled into a load module. Entire Net-Work licensing requires MLC135 or above.
See Software AG Mainframe Product Licensing for more information.
ADATCP now works with the Adabas Directory Server (ADI). See Adabas Directory Server Support above.
New parameters may be provided to ADATCP via the TCPIN DD statement. See New Simple Connection Line Driver (TCPX) DRIVER and LINK Parameters below for details.
Internal enhancements have been made to ADATCP to improve stability and robustness.
ADATCP now runs in zIIP mode when the Adabas session has zIIP active.
The following table summarizes the new Simple Connection Line Driver (TCPX) DRIVER and LINK parameters introduced:
| Parameter | DRIVER or LINK Statement? | New or Changed? | Description | Introduced in Release |
|---|---|---|---|---|
| ADI | DRIVER | New | This parameter was added to the TCPX line driver in this release. It specifies whether Adabas Directory Server (ADI) support is enabled or disabled. | 6.5 SP1 |
| ADIHOST | DRIVER | New | This new parameter specifies the hostname of the Adabas Directory Server (ADI). The hostname is used to attempt to acquire the TCP/IP address of the system where the ADI resides. | 6.5 SP1 |
| ADIPART | DRIVER | New | This new optional parameter specifies the partition name to be used with the Adabas Directory Server (ADI). If specified, the partition name will be included in all target entries added to the ADI by this session. Partitions are used to restrict database access; when an application queries the ADI for a target and specifies a partition, only entries with the same partition name are returned. Likewise, if the query does not specify a partition, only entries that do not have a partition are returned. | 6.5 SP1 |
| ADIPORT | DRIVER | New | This new parameter specifies the port number used to communicate with the Adabas Directory Server (ADI). | 6.5 SP1 |
| WCPPART | DRIVER | New | This new optional parameter is an alias of ADIPART and works in the same way as ADIPART. | 6.5 SP1 |
