 NAME
      hostvar - A dcecp task object that manages the security binary
      compatibility attributes

 SYNOPSIS
      hostvar help [operation | -verbose]

      hostvar operations

      hostvar set -secbinarycompat {on | off}

      hostvar show {-all |  [-cellname] [-hostname] [-secbinarycompat]}

 ARGUMENTS
      The name of the hostvar operation for which to display help
      information.

 DESCRIPTION
      The hostvar object allows you to easily set the security binary
      compatibility attributes for the current host and to display the local
      host's cellname, hostname, and security binary compatibility
      attributes that are stored by the dced in the hostdata/dce_cf.db
      object.

      The cell's security server uses these compatibility attributes to
      determine the mode and state in which the local machine is operating.

 ATTRIBUTES
      The name of the cell in which the local host is registered.  The name
      of the local host.  The security binary compatibility attribute that
      enables (on) and disables (off) binary compatibility for statically
      linked versions of DCE.

 OPERATIONS
    hostvar help
      Returns help information about the hostvar task object and its
      operations. The syntax is as follows: hostvar help [operation |
      -verbose]

      Options Displays information about the hostvar task object.

      Used without an argument or option, the hostvar help command returns
      brief information about each hostvar operation. The optional operation
      argument is the name of an operation about which you want detailed
      information.  Alternatively, you can use the -verbose option to
      display detailed information about the hostvar task object itself.

      Privileges Required

      No special privileges are needed to use the hostvar help command.

      Examples

      dcecp> hostvar help.ft3 set		  Sets the value of the
      specified host variable. show		   Returns the value of the
      specified host variable. help		   Prints a summary of
      command-line options. operations		Returns a list of the valid
      operations for this command. dcecp>

    hostvar operations
      Returns a list of the operations supported by the hostvar task object.
      The syntax is as follows: hostvar operations

      The list of available operations is in alphabetical order except for
      help and operations, which are listed last.

      Privileges Required

      No special privileges are needed to use the hostvar operations
      command.

      Examples

      dcecp> hostvar operations.ft3 set show help operations dcecp>

    hostvar set
      Sets the security binary compatibility value attribute for the local
      host. The syntax is as follows:
       hostvar set -secbinarycompat {on | off}

      Options Sets the security binary compatibility attribute on or off.

      Under normal circumstances, secbinarycompat is set to on when DCE is
      configured, which allows binary compatibility between Version 1.2 and
      Versions 1.0.3 and 1.1. Binary compatibility allows applications
      linked with an archived libdce to share login contexts and credentials
      without loss of data.

      To prepare a host for the set operation, a number of steps need to be
      performed first: Verify that the dced process is running in remote
      access mode (-r), then put the DCE daemon into partial service mode by
      sending the dced process the correct signal: # kill -SIGUSR1
      pid_of_dced # Invoke dcecp with the -local option: # dcecp -local
      dcecp>&gt&gt> As the machine principal (usually root), modify ACLs on the
      local hostdata object to allow the self user access by using the
      following dcecp acl operations: dcecp> acl modify hostdata -change
      {user hosts/hostname/self criI} -local.ft3 dcecp> acl modify hostdata
      -change {user hosts/hostname/self cdprw} -io -local.ft3 dcecp> Put the
      DCE daemon back into full service mode with the following command: #
      kill -SIGUSR1 pid_of_dced #

      Now, as the machine principal, you can set the hosts security binary
      compatibility value.

      You can disable binary compatibility on a per-host basis to achieve
      minor performance gains and slightly smaller credentials files by
      setting secbinarycompat to off. If you enable binary compatibility
      after it has been disabled, you must stop and start all DCE daemons
      and if you are using integrated login, log out and in.  See Planning
      and Configuring HP DCE for more information. This operation returns an
      empty string on success.

      Privileges Required

      No special privileges are needed to use the hostvar set command.

      Examples

      dcecp> hostvar set -secbinarycompat on.ft3 dcecp>

    hostvar show
      Returns the values of the host attributes on the local host. The
      syntax is as follows: hostvar show {-all |  [-cellname] [-hostname]
      [-secbinarycompat]}

      Options Returns the values of all attributes. Returns the value of the
      cellname attribute. Returns the value of the hostname attribute.
      Returns the value of the secbinarycompat attribute.

      The show operation makes it easy to view the attributes stored in the
      dced hostdata/dce_cf.db object.  All the values returned by this
      command are from that object. Use the -all option to display all
      attributes; use individual options to display individual attributes.

      Privileges Required

      No special privileges are needed to use the hostvar show command.

      Examples

      dcecp> hostvar show -all.ft3 {cellname /.../gumby1} {hostname
      hosts/blech} {secbinarycompat on} dcecp>
