Patch-ID# 100850-02 Keywords: SNA3270 IBMFTP Performance Synopsis: SNA3270 7.0.1: patch for IBMFTP performance problem Date: Jan/29/93 SunOS release: OS 4.1.1, 4.1.2, 4.1.3 Unbundled Product: SunLink SNA3270 Unbundled Release: 7.0.1 Topic: patch for IBMFTP performance problem BugId's fixed with this patch: 1095220 1098403 Changes incorporated in this version: 1095220 Architectures for which this patch is available: sun4(all) Patches which may conflict with this patch: Obsoleted by: Problem Description: This patch replaces patch 100850-01. It includes the fix from that patch, and a fix from patch 100528-03. Most of the fixes from 100528-03 were included in Release 7.0.1. Bugid 1095220, however, was not. That fix is included in this patch. Bug# 1095220 HLI application randomly fails with large file transfer to VM/SP machine. Bug# 1098403 File transfer performance for ibmftp and hli/td3278 is quite slow (3000 bytes/sec). Note that improved performance with this patch can only be achieved by increasing the MAXDATA size on the Sun, and the Maximum RU size on the host. The recommended values to achieve optimal performance are 4105 bytes for MAXDATA, and 4 * MAXDATA for the maximum RU size. INSTALL: Replace the 'td3278-tn', 'td3278', 'HLIB.a', 'sna3274', ibmftp', and 'te3278' files with those provided with this patch. # mv /sunlink/dai/hli/td3278-tn /sunlink/dai/hli/td3278-tn.orig # mv /sunlink/dai/hli/td3278 /sunlink/dai/hli/td3278.orig # mv /sunlink/dai/hli/HLILIB.a /sunlink/dai/hli/HLILIB.a.orig # mv /sunlink/3270/sna3274 /sunlink/3270/sna3274.orig # mv /sunlink/3270/ibmftp /sunlink/3270/ibmftp.orig # mv /sunlink/3270/te3278 /sunlink/3270/te3278.orig # cp dai/hli/td3278-tn /sunlink/dai/hli/td3278-tn # cp dai/hli/td3278 /sunlink/dai/hli/td3278 # cp dai/hli/HLILIB.a /sunlink/dai/hli/HLILIB.a # cp 3270/sna3274 /sunlink/3270/sna3274 # cp 3270/ibmftp /sunlink/3270/ibmftp # cp 3270/te3278 /sunlink/3270/te3278
