NetWare SET Parameters

When you first install NetWare 6.5, the operating system is tuned by default so that its performance is optimized for most systems. Over time, the server optimizes itself according to the network usage it encounters. Occasionally, however, you might find that you want to make manual changes to your system in some aspect of the server's operation. This is particularly true if you are reconfiguring a server specifically to run a different set of service than what is currently configured.

For this reason, there are numerous server parameters you can set to change the way the server handles things such as memory or file locks. These server parameters, also called SET parameters, can be set in several ways:

• NoRM: Open the SET parameters page to access all NetWare 6.5 SET parameters, by category.

• MONITOR.NLM: Provides menu-driven access to SET parameters from the server console. Select Server Parameters from the main menu.

• SET console command: You can change any SET parameter individually by using the following general syntax:

   SET <  parameter name  > = <  value  > 

In most cases, you might not need to change any server parameters. However, if you need to change them, each server parameter is explained in this appendix. There are 14 SET parameter categories in NetWare 6.5. Within each category there are hidden and unhidden parameters. Hidden parameters are viewable through NoRM by selecting the View Hidden SET Parameters setting on the Set Parameters page. However, information is limited for these parameters and they should be adjusted only if you are absolutely sure of the consequences. The following sections list some, but not all, of the hidden parameters. Use NoRM for a complete listing of potential settings.

Common File System

This category sets basic file system parameters common to both NSS and traditional volumes , including compression characteristics. Table C.10 describes the Common File System parameters.

Time

Initially, you set up time services on the server during installation. Time services are controlled by TIMESYNC.NLM, which is loaded automatically when the server is started up. To modify time synchronization after installation, use the Time SET parameters, which are described in Table C.22.

All parameters that start with the word TIMESYNC are elements of the TIMESYNC.CFG file. NetWare 6.5 now updates the TIMESYNC.CFG file automatically when you make changes to these settings. You can use EDIT.NLM to modify the TIMESYNC.CFG file directly.

Table C.22. Time SET Parameters

PARAMETER	VALUES	DESCRIPTION
TIMESYNC configuration file	path\filename (Default: SYS: SYSTEM\TIMESYNC.CFG )	Specifies the directory and filename of the time synchronization configuration file.
TIMESYNC configured sources	ONOFF (Default: OFF)	When set to ON , the server ignores SAP (Service Advertising Protocol) time sources and instead accepts time sources configured with the TIMESYNC Time Source parameter. When this parameter is turned OFF , it causes the server to listen to any advertising time source.
Start of daylight savings time	Max 79 char (First Sunday in April @0200)	Indicates the day that daylight saving time begins locally. To specify the beginning of daylight saving time so it recurs every year, enclose the date and time in parentheses, and use the following format: (April Sunday First 2:00:00 a.m.) . If you do not enclose the date in parentheses, the change will occur only in the current year. "April Sunday First" indicates that the change occurs on the first Sunday in April.
End of daylight savings time	Max 79 char (Default: Last Sunday in October @0200)	Indicates the day that daylight saving time ends locally. To specify the end of daylight saving time so it recurs every year, enclose the date and time in parentheses, and use the following format: (October Sunday Last 2:00:00 a.m.) . If you do not enclose the date in parentheses, the change will occur only in the current year. "October Sunday Last" indicates that the change occurs on the last Sunday in October.
Daylight savings time offset	+or- hour:minute:second (Default: +1:00:00)	Specifies the offset applied to time calculations when daylight saving time is in effect, causing UTC time to be recalculated from local time.
Daylight savings time status	ONOFF (Default: NA)	When set to ON , this parameter indicates that daylight saving time is currently in effect. Changing this parameter does not change the local time on the server.
New time with daylight savings time status	ONOFF (Default: ON)	When set to ON , the local time on the server is adjusted by adding or subtracting the time indicated in the Daylight saving time offset parameter.
TIMESYNC directory tree mode	ONOFF (Default: ON)	When set to ON , time synchronization ignores SAP (Service Advertising Protocol) packets that don't originate from within the server's Directory tree. When this parameter is set to OFF , the server accepts SAP packets from any time source on the network, regardless of the tree from which it originates. If SAP is turned on, this parameter should also be set to ON .
TIMESYNC polling count	11000 packets (Default: 3)	Specifies the number of time packets to exchange while polling. Increasing this number might increase unnecessary traffic on the network.
TIMESYNC polling interval	10 to 2678400 sec (Default: 600)	Determines the polling interval, in seconds. All servers in the tree must use the same polling interval. Maximum works out to 31 days.
TIMESYNC RESET	ONOFF (Default: OFF)	When set to ON , all servers are removed from the time source list, and time synchronization is reset. This parameter automatically resets itself to OFF after execution.
TIMESYNC restart flag	ONOFF (Default: OFF)	When set to ON , the TIMESYNC service automatically restarts. This parameter automatically resets itself to OFF after execution.
TIMESYNC service advertising	ONOFF (Default: ON)	When set to ON , SAP (Service Advertising Protocol) is turned on, meaning Single Reference, Reference, and Primary time sources advertise using SAP. Set this parameter OFF if you are using a configured list of time sources.
TIMESYNC synchronization radius	0 to 2147483647 msec (Default: 2000)	Determines the maximum time that a server is allowed to drift from network time while still being synchronized. Do not set this parameter for under two seconds (2000 milliseconds ) unless you have an application that uses synchronized time stamps that will not tolerate a two-second deviation between time sources.
TIMESYNC time adjustment	+or- hour:minute:second [at month/day/year hour:minute:second]	Determines when a time adjustment will take place. This parameter does not apply to Secondary time servers. Use sparingly to correct network-wide time errors. Overuse can corrupt time synchronization. The default date and time is six polling intervals or one hour (whichever is longer) from the current time.
TIMESYNC time sources	Max 150 char (Default: ;)	Specifies a server, or servers, as accepted time sources. If used at the console, and no server name is entered, the parameter displays the list of configured servers. To specify multiple servers, separate each one by a semicolon (;). The list of servers must contain at least one semicolon, even if only one server is listed. A semicolon alone clears the list of servers.
TIMESYNC type	Single, Reference, Primary, Secondary	Specifies the type of time sync role this server will play in the network. Default is Single for the first server in the tree, and Secondary for all subsequent servers. See Chapter 6 for more information on time synchronization.
Time zone	Max 80 char (Default: NA)	Specifies the abbreviation for the server time zone, its offset from UTC (Universal Coordinated Time, which used to be called Greenwich Mean Time), and the daylight savings abbreviation, if applicable . For example: zone is MST7MDT for mountain standard time in the U.S.A. Mountain standard time is offset seven hours from UTC, and the abbreviation used when daylight saving time is in effect is MDT.
Default time server type	Max 50 char (Default: Secondary)	Specifies the type of time server for this server.

Traditional File System

A new category with NetWare 6.5, Traditional File System, includes all kinds of parameters relating to traditional NetWare volumes. If you are familiar with SET parameters from NetWare past, this category combines parameters from several different areas. So, if you can't find it, it might very well be right here. Table C.23 describes the traditional file system parameters in NetWare 6.5.
