1  WRITE
   Writes the system parameter values and the name of the site-
   independent startup command procedure from the SYSGEN work area
   to a parameter file, the current system parameter file on disk,
   or the active system in memory.

   Format

     WRITE  file-spec
 

2  Parameters
 

file-spec

   The file specification of a new parameter file to be created. The
   default file type is .PAR.

   In place of a file specification, you can specify one of the
   following keywords:
 

CURRENT

   Specifies that source information is to be written to the current
   system parameter file on disk. The new values will take effect
   the next time the system is booted.

   On Alpha systems, the system parameter file is
   SYS$SYSTEM:ALPHAVMSSYS.PAR.

   On Integrity servers, the system parameter file is
   SYS$SYSTEM:IA64VMSSYS.PAR.

   Use of the WRITE CURRENT command requires the SYSPRV privilege.


ACTIVE

   Specifies that source information is to be written to the active
   system in memory. The new values of dynamic parameters will take
   effect immediately. (Only the dynamic parameter values are
   written to the active system.)

   Use of the WRITE ACTIVE command requires the CMKRNL privilege.
 

2  Qualifiers
   None.
 

2  Description

   System managers can receive notification of a change to the
   system parameter file by setting up an access control list (ACL)
   on the file to signal such an event, as in the following example:

   $ SET SECURITY/ACL=(ALARM=SECURITY,ACCESS=WRITE+FAILURE+SUCCESS)-
   _$ SYS$SYSTEM:X86_64VMSSYS.PAR

   For more information about setting ACLs, refer to the VSI OpenVMS
   User's Manual and the VSI OpenVMS Guide to System Security.

   Both the WRITE ACTIVE and WRITE CURRENT commands send a message
   to OPCOM and log the event. The audit log also provides a list of
   the changed parameters along with their old and new values.


2  Examples

   1.SYSGEN> WRITE SYS$SYSTEM:SPECIAL

     This command creates a new parameter specification file,
     SYS$SYSTEM:SPECIAL.PAR.

   2.SYSGEN> WRITE CURRENT

     On x86 systems, command modifies the current system
     parameter on disk, X86_64VMSSYS.PAR.

     On Integrity servers, this command modifies the current
     system parameter file on disk, IA64VMSSYS.PAR.

     On Alpha systems, this command modifies the current system
     parameter file on disk, ALPHAVMSSYS.PAR.
