SNA_LU6 SNALU62_E21022 DECnet SNA APPC/LU6.2 V2.2 OpenVMS ECO Summary

Modification Date: 05-JUN-98 Modification Type: DOCUMENTATION: Technical Modification: This kit is a full product replacement. NOTE: An OpenVMS saveset or PCSI installation file is stored on the Internet in a self-expanding compressed file. The name of the compressed file will be kit_name-dcx_vaxexe for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha. Once the file is copied to your system, it can be expanded by typing RUN compressed_file. The resultant file will be the OpenVMS saveset or PCSI installation file which can be used to install the ECO. Copyright (c) Digital Equipment Corporation 1996. All rights reserved. PRODUCT: DECnet SNA APPC/LU6.2 Programming Interface for OpenVMS, V2.2 OP/SYS: OpenVMS VAX V5.5-2 or later OpenVMS AXP V6.1 or later SOURCE: Digital Equipment Corporation ECO INFORMATION: ECO Kit Name: SNALU62_E21022 ECO Kits Superseded by This ECO Kit: SNALU62_E20022 ECO Kit Approximate Size: SNALU62_E21022.A 12546 Blocks System Reboot Necessary: No ECO KIT SUMMARY: An ECO kit exists for DECnet SNA APPC/LU6.2 Programming Interface for OpenVMS V2.2 on OpenVMS VAX V5.5-2 or later or OpenVMS AXP V6.1 or later. This kit addresses the following problems: o Programs hung when transferring data block greater than 4064 bytes in a MAPPED conversation. The reason being was that the LU6.2 didn't recognize the length continuation indicator bit was turned on. o snalu62$send_error would hang in the confirm_send state. o Access violation caused by an obscure/rare stack corruption problem. o A problem resulted from using a resource id that was no longer valid. When this occurred LU6.2 would report a routine name with garbage and then access violate. This only happened on the Alpha AXP platform. o Another access violation, this time due to improper memory management after LU6.2 called localtime(). This only happened on the Alpha AXP platform. INSTALLATION NOTES: The ECO kit can be installed with the VMSINSTAL command procedure, as outlined in Chapter 3 of the VMS System Manager's Manual (AA-LA00A-TE). The installation procedure for the DECnet SNA OpenVMS APPC-LU6.2 Programming Interface will install SNALU62SHR.EXE and SNALU62MG.EXE as shareable images. To install the APPC-LU6.2 on other nodes that share a common system disk in a cluster environment, run the SYS$MANAGER:SNALU62$STARTUP.COM command procedure on each node. For nodes in a cluster environment that do not share a common system disk, APPC-LU6.2 will have to be installed on each node. Verification of the installation can be done either during installation through the VMSINSTAL utility or at any other time by running the SNALU62$IVP.COM command procedure found in SYS$TEST. This command procedure only verifies that the APPC-LU6.2 has been installed correctly on your system. It does not verify connectivity to the IBM via the DECnet SNA Gateway or VMS/SNA. Installing the SNA-APPC-LU6.2 ECO Kit ------------------------------------- If your ECO kit is named "SNALU62_E21022.A", then $ @SYS$UPDATE:VMSINSTAL SNALU62_E21022
