server, without buffering them first. Setting the tcpnodelay option to yes(the default) can improve performance in higher-speed networks. Thisoption has been extended to all UNIX and Linux clients, except UNIXSystem Services client for z/OS ® . Table 3 lists the default values whichhave been optimized to improve performance. See “Tcpnodelay” on page365 for more information.Table 3. Optimized option default valuesOption Change Pagediskbuffsize Allows you to specify I/Obuffer size (in kilobytes) thatthe client can use to optimizebackup, archive, or HSMclient performance.224Recommendation: Use thedefault value instead ofspecifying the diskbuffsizeoption.largecommbuffers This option has beenreplaced by the diskbuffsizeoption. At this time,largecommbuffers willcontinue to be accepted bythe Tivoli Storage Managerclient in order to ease thetransition to the new option.However, the value specifiedby largecommbuffers will beignored in favor of thediskbuffsize setting.Recommendation:Discontinue the use oflargecommbuffers becausefuture releases of TivoliStorage Manager might notaccept this option.tcpadminport Specifies a separate TCP/IPport number on which theserver is waiting for requestsfor administrative clientsessions, allowing secureadministrative sessionswithin a private network. Ifthis option is not specified,the default value is the valueof the tcpport option.tcpbuffsize The default value waschanged from 31 kilobytes to32 kilobytes.224360361xxvi IBM Tivoli Storage Manager for UNIX and Linux: Backup-Archive Clients Installation and User’s Guide
Table 3. Optimized option default values (continued)Option Change Pagetcpnodelay The default value waschanged from no to yes.tcpnodelay yes disables theTCP/IP Nagle algortihm.This algorithm is used toreduce the number of smallsegments sent across thenetwork, but in someenvironments this mightnegatively impact TivoliStorage Managerperformance.365Recommendation: Use thedefault of yes, unless youfully understand the effectsof the TCP Nagle algorithmon network transmissionsand how its use affects theperformance of TivoliStorage Manager in yourenvironment.tcpwindowsize The default value waschanged from 32 kilobytes to63 kilobytes.txnbytelimit The default value waschanged from 2048 kilobytesto 25600 kilobytes.368375Technical changes for Version 5.2.2 - December 2003The following changes have been made to the product for this edition:Tivoli Storage Manager backup-archive client Linux on iSeriesThe Tivoli Storage Manager backup-archive client supported features onLinux for iSeries are the same as those supported by the Linux for pSeriesclient. See Chapter 1, “Installing Tivoli Storage Manager,” on page 1 forenvironment and installation information.Tivoli Storage Manager backup-archive client for Linux on Intel ItaniumThe Tivoli Storage Manager backup-archive client for Linux on IntelItanium (Linux IA64 client) supports these file systems and their ACLs: xfs,ext2, and ext3. As with the Linux x86/x86_64 client, the Linux IA64 clientsupports the reiserfs file system, but not its ACLs.The Tivoli Storage Manager Linux IA64 client supports the same functionsas the Linux x86/x86_64 client, except the following:v Backup-archive Native Graphical User Interface (Motif GUI).v LAN-free data transfer.v Cluster support.See Chapter 1, “Installing Tivoli Storage Manager,” on page 1 forenvironment and installation information.Summary of changes for Tivoli Storage Manager xxvii
