Supported Features

  • Artigo

This topic lists the features that are supported over the IP-DLC link service.

Base SNA Features

The following existing Host Integration Server SNA features are supported over the IP-DLC link service:

  • LU types 0, 1, 2, 3 and 6.2 (dependent and independent)

  • LUA, FMI, APPC, and CPI-C APIs

  • Dynamically Defined Dependent LUs (DDDLUs)

  • Dynamic addition of local LUs, remote LUs, and connections

  • Incoming and outgoing calls

  • Connection Activation at Server startup, on demand or by administrator

  • SNA data compression

  • PU concentration with the upstream link over IP-DLC

    Because the preceding SNA features are supported, it follows that the following applications are also supported over the IP-DLC link service:

  • Host Integration Server-compatible 3270 emulators

  • Host Integration Server-compatible 5250 emulators

  • APPC - 3270 Session Viewer (including the LU-LU Test feature)

  • Host Print Service

  • Data Integration Services (data providers for DB2 and host files)

  • Local and remote administration

  • TN3270 server

  • TN5250 server

  • Session Integrator

  • Message Integration (WCF Channel for WebSphere MQ)

  • Application Integration Transaction Integrator

  • BizTalk Adapters

Fault Tolerance Features

Note that because the IP-DLC link service uses the APPN and HPR/IP protocols, it is automatically able to take advantage of the following fault tolerance features:

  • Ability to reroute sessions around a failure in the network provided that an alternative route exists.

  • Ability for mainframe applications to be moved to a different processor with little or no impact to users when system or application failures occur on the mainframe.

Security Features

Because the IP-DLC link service uses UDP/IP, the Windows IPsec feature can be used to provide end-to-end data security over the IP-DLC link service. Windows handles configuration of IPsec independently. No specific configuration is required for the IP-DLC link service.

Diagnostic Features

The diagnostics provided by the IP-DLC link service are used through the Host Integration Server Tracer Initiator and Trace Viewer facilities.
