Administering SNAplus2

Enabling and Disabling SNAplus2 on the Local System

If a 3270 emulation program is using LUs on the node when you disable the SNAplus2 software, all 3270 emulation sessions using these LUs end. The program continues to run, but the user cannot use the sessions until the software is re-enabled. If the RJE workstation program is running, it automatically exits. Applications using the APPC, CSV, LUA, NOF, or MS APIs are notified by a COMM_SUBSYSTEM_ABENDED return code, HLLAPI applications by a HARC_SYSTEM_ERROR return code, and CPI-C applications by a CM_PRODUCT_SPECIFIC_ERROR return code.

To disable the SNAplus2 software, enter the following command at the HP-UX command prompt:

snap stop

If SNAplus2 is disabled successfully, snap stop returns an exit code of 0. Any other exit code indicates that an error occurred and that the SNAplus2 software was not disabled. Refer to the HP-UX SNAplus2 Diagnostics Guide for more information about exit code values.
