This command connects the device named LPA0 to the driver named LP2DRIVER and loads the driver if it is not already loaded.

SYSGEN> CONNECT NET/NOADAPTER/DRIVER=NETDRIVER
      

This command connects the device named NET to the driver NETDRIVER and loads the driver if it is not already loaded.

Creates a file that can be used as a page, swap, or dump file. Normally, this command is used indirectly by executing the command procedure SYS$UPDATE:SWAPFILES.

Format

CREATE file-spec

Parameter

file-spec

The name of the file to be created.

Qualifiers

/CONTIGUOUS

/NOCONTIGUOUS

Specifies that the created file is either to be contiguous (/CONTIGUOUS) or contiguous-best-try (/NOCONTIGUOUS). You must specify /NOCONTIGUOUS, which is the default, if you are creating a secondary page or swap file that spans volumes in a volume set.

/SIZE=block-count

Specifies the size in blocks of the file to be created.

Example

SYSGEN>  CREATE DISK$PAGE:[NODE1]PAGEFILE.SYS /SIZE=200000
      

This command creates a file called PAGEFILE.SYS on the disk DISK$PAGE: in directory [NODE1]. This file is created as a contiguous-best-try file, which is the default. SYSGEN creates the file with 200,000 blocks, or allocates as many blocks on the disk as it can and displays a message warning that the file does not have the full allocation specified with the CREATE command.

The file will not be used for paging or swapping until you use the SYSGEN command INSTALL specifying the file and how it is to be used.

Deinstalls a page or swap file. Requires CMKRNL privilege. Any file installed with the SYSGEN command INSTALL can be deinstalled.

If the specified file is being actively used by processes, this command simply marks the file as "deinstall pending". This prevents any new assignments or reservations to the file from occurring. When all outstanding references to the file have been removed, the deinstallation will complete.

Files in the deinstall pending state are identified in the DCL command SHOW MEMORY/FILES display.

Format

DEINSTALL file-spec

DEINSTALL/ALL

DEINSTALL/INDEX=n

Parameter

file-spec

Specifies the name of a file that is to be deinstalled as a page or swap file.

Qualifiers

/PAGEFILE

Specifies that the file to be deinstalled is a page file.

/SWAPFILE

Specifies that the file to be deinstalled is a swap file.

/ALL

Deinstalls all page and swap files currently installed on the system. This command is most useful during an orderly system shutdown procedure where all disk volumes are being dismounted.

No other parameters or qualifiers are allowed.

/INDEX=n

Deinstalls a page or swap file specified by page file index. The page file index is presented in the DCL command SHOW MEMORY/FILES/FULL display as "Page File Number."

No other parameters or qualifiers are allowed.

Example

SYSGEN>  DEINSTALL DRA1:[SYSEXE]PAGEFILE.SYS /PAGEFILE
      

Inhibits the checking that SYSGEN performs on parameter values. By default, range checking is enabled.

Format

DISABLE CHECKS

Parameters

None.

Qualifiers

None.

Requests that SYSGEN ensure that parameter values changed using the SET command remain in the allowable range. By default, the range checking is enabled.

Format

ENABLE CHECKS

Parameters

None.

Qualifiers

None.

INSTALL

Installs an additional page or swap file. Requires CMKRNL privilege.

Format

INSTALL file-spec

Parameter

file-spec

Specifies the name of a file that is to be installed as a page or swap file. This file can reside on any volume that is mounted /SYSTEM. The file should be contiguous for best performance.

Qualifiers

/PAGEFILE

Specifies that the file is to be installed as an additional page file. This page file will augment any page file installed during the boot process.

/SWAPFILE

Specifies that the file is to be installed as an additional swap file. This swap file will augment any swap file installed during the boot process.

Example

SYSGEN>  INSTALL DRA1:[SYSEXE]PAGEFILE.SYS /PAGEFILE
      

On VAX systems, loads an I/O driver. On Alpha systems, use the SYSMAN command IO LOAD.

Use of the LOAD command requires the CMKRNL privilege.

Note Be very careful when issuing a LOAD command because the system does little error-checking.

Format

LOAD file-spec

Parameter

file-spec

Specifies the file specification of the driver image to be loaded. This parameter is required.

If the entire file specification is the same as that of a driver already loaded, no load takes place. If only the file name is the same as that of a driver already loaded (but the file specification is different), the driver specified replaces the driver previously specified; that is, the existing driver.

The default file type is .EXE.

Description

Refer to the OpenVMS VAX Device Support Manual for a complete description of the LOAD command. (This manual has been archived but is available on the OpenVMS Documentation CD-ROM.)

Example

SYSGEN>  LOAD SYS$SYSTEM:RTTDRIVER
      

This command loads the standard driver for a remote terminal.

On VAX systems, replaces a loaded device driver with a new version.

Use of the RELOAD command requires the CMKRNL privilege.

Format

RELOAD file-spec

Parameter

file-spec

The file specification of the new driver image. The default file type is .EXE. The specified image is loaded and replaces any existing driver with the same file specification.

Qualifiers

None.

Description

Refer to the OpenVMS VAX Device Support Manual for a complete description of the RELOAD command. (This manual has been archived but is available on the OpenVMS Documentation CD-ROM.)

Example

SYSGEN>  RELOAD SYS$SYSTEM:RTTDRIVER
      

This command reloads the remote terminal driver.

Assigns a value to a system parameter in the SYSGEN work area.

This command does not modify parameter files, the current system parameter file on disk, or the active system; for information about performing these modifications, see the WRITE command.

Format

SET parameter-name value

Parameters

parameter-name

Specifies the name of a system parameter. If you enter a period (.), it is interpreted as a request for the system parameter specified in the last SET or SHOW command. See the description of the SHOW [parameter] command for an example of the use of the period in place of a parameter name.

value

Usually specifies an integer or the keyword DEFAULT. Integer values must be within the defined minimum and maximum values for the parameter unless the SYSGEN command DISABLE CHECKS was specified.

The keyword DEFAULT specifies the default value for the parameter. You can display the maximum, minimum, and default values for any parameter with the SYSGEN command SHOW [parameter].

You can specify values for certain SYSGEN parameters in hexadecimal or octal radixes and for others as an ASCII string. To specify a value in octal or hexadecimal, precede the value with %O or %X, respectively. To specify a value in ASCII, enclose the value string in quotation marks (" ").

Qualifiers

None.

Examples

SYSGEN> SET PFCDEFAULT 20
      

This command assigns a value of 20 to the PFCDEFAULT parameter.

SYSGEN> SET GBLSECTIONS DEFAULT
      

This command assigns the default value (40) to the GBLSECTIONS parameter.

Establishes a file to be used for output during the session. By default the output is written to SYS$OUTPUT, but you can use SET/OUTPUT to designate a disk file.

At any time you can direct the output back to SYS$OUTPUT by using the SET/OUTPUT=SYS$OUTPUT command.

Format

SET/OUTPUT[=] file-spec

Parameter

file-spec

The name of the output file. The default file type is .LIS. The equal sign (=) is optional.

Example

SYSGEN>  SET/OUTPUT=PARAMS.LIS
SYSGEN>  SHOW/ALL
SYSGEN>  SHOW/SPECIAL
SYSGEN>  EXIT
      

In this example, output is directed to the file PARAMS.LIS to capture a complete list of all the system parameters (including the SPECIAL parameters reserved for Compaq use) and their values.

Names the site-independent startup command procedure to be associated with a parameter file for subsequent bootstrap operations.

Format

SET/STARTUP file-spec

Parameter

file-spec

The file specification of a startup command procedure on the system disk (maximum of 31 characters). The initial site-independent startup command procedure (as named in the software distribution kit) is SYS$SYSTEM:STARTUP.COM.

Example

SYSGEN>  SET/STARTUP SYS$SYSTEM:XSTARTUP.COM
      

This command assigns SYS$SYSTEM:XSTARTUP.COM as the current site-independent startup command procedure.

On VAX systems, connects a processor to a multiport memory unit already initialized by this or another processor. The number and name of the specified multiport memory unit must be those of an initialized unit, or an error condition results.

Use of the SHARE command requires the CMKRNL privilege.

Format

SHARE MPMn MPM-name

Parameters

MPMn

Specifies the number on the front panel of the multiport memory unit being connected.

MPM-name

Specifies the name of the multiport memory unit as indicated in a previous SHARE/INITIALIZE command.

Qualifiers

/MAXCEFCLUSTERS=max-cef

Specifies the maximum number of common event flag clusters that the processor can create in the multiport memory unit. The default is no limit.

/MAXGBLSECTIONS=max-gbl

Specifies the maximum number of global sections that the processor can create in the multiport memory unit. The default is no limit.

/MAXMAILBOXES=max-mail

Specifies the maximum number of mailboxes the processor can create in the multiport memory unit. The default is no limit.

Example

SYSGEN>  SHARE MPM1 SHR_MEM_1
      

This command connects a multiport memory unit. Because no qualifiers are specified, defaults apply to all the parameters.

The unit with a 1 on the front panel must be initialized with the name SHR_MEM_1 for the command to work.

On VAX systems, initializes a multiport memory unit and connects it to the processor on which SYSGEN is running.

Use of the SHARE/INITIALIZE command requires the CMKRNL privilege.

Format

SHARE/INITIALIZE MPMn MPM-name

Parameters

MPMn

Specifies the number on the front panel of the multiport memory unit being connected.

MPM-name

Specifies the name by which the multiport memory unit is to be known to systems using it. The MPM-name is a 1 to 15 alphanumeric character string that may contain dollar signs ($) and underscores (_).

Qualifiers

/CEFCLUSTERS=cef

Specifies the total number of common event flag clusters permitted in the multiport memory unit. The cef value is an integer with a default of 32.

/GBLSECTIONS=gbl

Specifies the total number of global sections permitted in the multiport memory unit. The gbl value is an integer with a default of 32.

/MAILBOXES=mail

Specifies the total number of mailboxes permitted in the multiport memory unit. The mail value is an integer with a default of 32.

/MAXCEFCLUSTERS=max-cef

Specifies the maximum number of common event flag clusters that the processor can create in the multiport memory unit. The default is no limit.

/MAXGBLSECTIONS=max-gbl

Specifies the maximum number of global sections that the processor can create in the multiport memory unit. The default is no limit.

/MAXMAILBOXES=max-mail

Specifies the maximum number of mailboxes the processor can create in the multiport memory unit. The default is no limit.

/POOLBCOUNT=block-cnt

Specifies the number of blocks allocated to the multiport memory unit's dynamic pool. The block-cnt value is an integer with a default of 128.

/POOLBSIZE=block-size

Specifies the size of each block in the dynamic pool. The block-size value is an integer with a default of 128 bytes.

/PRQCOUNT=prq-cnt

Specifies the number of interprocessor request blocks (PRQs) allocated. The prq-cnt value is an integer with a default of 64.

Description

If the specified multiport memory unit is already initialized and connected to other active processors, the gbl, mail, cef, block-cnt, block-size, and prq-cnt parameter values are ignored, and the unit is simply connected to the processor.

Example

SYSGEN>  SHARE MPM1 SHR_MEM_1/INITIALIZE -
SYSGEN>  /GBLSECTIONS=128/MAILBOXES=64/CEFCLUSTERS=0
      

This command initializes a multiport memory unit with defaults on all but the gbl, mail, and cef parameters. In this example, assume that the number of the multiport memory unit as it appears on the front panel is 1, and the unit name is SHR_MEM_1.

Displays the values of system parameters in the SYSGEN work area, plus the default, minimum, and maximum values of the parameters and their units of measure.

Format

SHOW [parameter-name]

Parameter

parameter-name

Specifies the name of a system parameter. If you enter a period (.), it is interpreted as a request for the system parameter specified in the last SET parameter-name or SHOW [parameter] command.

Qualifiers

/ACP

Specifies that all ACP parameter values are displayed.

/ALL

Specifies that all parameter values other than SPECIAL parameter values are displayed.

/BI

Specifies that device addresses that are currently mapped in the I/O space for the VAXBI bus are displayed.

/CLUSTER

Specifies that all CLUSTER parameter values are displayed.

/DYNAMIC

Specifies that all DYNAMIC parameter values are displayed.

/GEN

Specifies that all GEN parameter values are displayed.

/HEX

Specifies that the values of parameters be displayed in hexadecimal representation. Specify the /HEX system parameter name or the parameter type. If you specify the /HEX qualifier with the /NAMES qualifier, /HEX is ignored.

/JOB

Specifies that all JOB parameter values are displayed.

/LGI

Specifies that all LGI parameter values are displayed.

/MAJOR

Specifies that all MAJOR parameter values are displayed.

/MULTIPROCESSING

Specifies that all MULTIPROCESSING parameters are displayed.

/NAMES

Specifies that the names of all parameters are displayed.

/PQL

Specifies that all PQL parameter values are displayed.

/RMS

Specifies that all RMS parameter values are displayed.

/SCS

Specifies that all SCS parameter values are displayed.

/SPECIAL

Specifies that all parameter values reserved for Compaq use are displayed.

/STARTUP

Specifies that the name of the current site-independent startup command procedure is displayed.

/SYS

Specifies that all SYS parameter values are displayed.

/TTY

Specifies that all terminal parameter values are displayed.

/XMI[=BIindex]

Specifies that device addresses that are currently mapped in the I/O space for the XMI bus are displayed. The /XMI qualifier also displays node and nexus numbers and generic names of all processors, adapters, VAXBI adapters, memory controllers, and interconnection devices such as the NI.

Use of the SHOW/XMI=BIindex command requires the CMEXEC privilege.

Description

Parameter values are displayed in decimal unless the /HEX qualifier is specified. Note that ASCII values are displayed in ASCII by default.

When parameter names are abbreviated on a VAX platform, the first parameter matching the abbreviation is selected for display. No ambiguity checks are made. On an Alpha platform, all parameters whose names match the abbreviation will be printed.

For example, a specification of SHOW GBL on a VAX displays only the GBLSECTIONS parameter. To display the GBLPAGFIL parameter, you must specify SHOW GBLPAGF (to avoid further ambiguity with the GBLPAGES parameter). On an Alpha, the same SHOW GBL command will display GBLSECTIONS, GBLPAGES, and GBLPAGFIL.

You can enter a period (.) to indicate that you want to work with the system parameter that was specified in the last SET parameter-name or SHOW [parameter] command.

Examples

SYSGEN> SHOW GBLSECTIONS





  

    

      

      




GBLSECTIONS           100        40        20        -1  Sections
SYSGEN> SET . 110
SYSGEN> SHOW .
GBLSECTIONS           110        40        20        -1  Sections




      

In this example, the user first displays the values of the GBLSECTIONS parameter and then refers to the parameter with a period to set its current value to 110. The next SHOW command also uses the period notation to obtain confirmation that the change occurred.

SYSGEN> SHOW/ACP
      

On a VAX system, the command in this example produces the following output:
