Using SNAplus2 in a High Availability Environment

SNAplus2 High Availability Features

Table D-1
		Component	Primary Server	Backup Server
	System Name		hp_pri	hp_back
	SNAplus2 Node		HANODE	DEVNODE
	SNAplus2 Port		HAPORT	DEVPORT
	SNAplus2 LS		HALS	DEVLS
	SNAplus2 Local LU aliases		HALU01...HALU09	DEVLU01...DEVLU05
		The above example will be used throughout this appendix to explain
NOTE
		many different aspects of high availability systems.

In this example, nine LUs are used by APPC production applications that run on the client systems. These LUs are configured to use an SNAplus2 LS called HALS. This LS is configured to use the SNAplus2 LAN port HAPORT and can be run under the SNAplus2 node HANODE. Normally, this configuration is run on the primary server hp_pri as shown below. In addition, five LUs are used by APPC transaction programs for development purposes. These LUs are configured to use an SNAplus2 LS called DEVLS. This LS is configured to use the SNAplus2 LAN port DEVPORT, and can be run under the SNAplus2 node DEVNODE. Normally, this configuration is run on the backup server hp_back as shown below.
