ARGUMENTS [Toc] [Back]
operation The name of the rpcgroup operation for which to display help
information.
rpcgroup_name_list
Specifies a list of one or more names of the RPC groups to
be operated on.
DESCRIPTION [Toc] [Back]
The rpcgroup object represents a remote procedure call (RPC) group
entry in the Cell Directory Service (CDS). Each RPC group is named in
the DCE namespace; therefore, each operation takes as an argument a
list of names of group entries to manipulate. An RPC group is a
container that contains only the names of RPC server entries or the
names of other RPC groups; it contains no other data.
DATA STRUCTURES [Toc] [Back]
interface_id
The interface identifier of an RPC interface. The interface
identifier takes the following form:
interface-uuid,major-version.minor-version
The version numbers are optional. If you omit a version
number, the default is 0. The UUID is a hexadecimal string
and the complete version number is a decimal string. For
example:
Hewlett-Packard Company - 1 OSF DCE 1.1/HP DCE 1.8 PHSS_26394-96
rpcgroup(1m) Open Software Foundation rpcgroup(1m)
-interface ec1eeb60-5943-11c9-a309-08002b102989,3.11
Leading zeros in version numbers are ignored.
Alternatively, you can use Tcl syntax. For example:
-interface {458ffcbe-98c1-11cd-bd93-0000c08adf56 1.0}
object_uuid
The UUID of an object. The UUID is a hexadecimal string,
for example:
-object 3c6b8f60-5945-11c9-a236-08002b102989
Alternatively, you can use Tcl syntax. For example:
-object {3c6b8f60-5945-11c9-a236-08002b102989}
OPERATIONS [Toc] [Back]
rpcgroup add
Adds a member to the specified group entry in CDS. The syntax is as
follows:
rpcgroup add rpcgroup_name_list -member member_name_list
Options [Toc] [Back]
-member member_name_list
This required option declares the name of a member to be
added to the specified group entry. The member_name_list
argument is a list of names of one or more members to be
added to all of the specified groups. (The names need not
exist when they are added.) All members are added to all
groups.
The add operation adds a member to the specified group entry in CDS.
The required rpcgroup_name_list argument is a list of one or more full
CDS names of the groups to which you want to add members. This
operation returns an empty string on success. If member_name_list
contains the names of duplicate or existing members, the duplicates
are ignored and no errors are generated.
Privileges Required [Toc] [Back]
You need i (insert) permission to the parent directory. You also need
both r (read) permission and w (write) permission to the CDS object

entry (the target group entry).
Examples [Toc] [Back]
The following command adds the member /.:/LandS/anthro/Cal_host_3 to
the group /.:/LandS/anthro/Calendar_group:
dcecp> rpcgroup add /.:/LandS/anthro/Calendar_group \
-member /.:/LandS/anthro/Cal_host_3
dcecp>
rpcgroup create
Creates an empty RPC group entry in CDS. The syntax is as follows:
rpcgroup create rpcgroup_name_list
The create operation creates a new (empty) RPC group entry in CDS.
Since an empty group is the same as an empty RPC entry or RPC profile,
calling rpcgroup create is the same as calling rpcentry create or
rpcprofile create. The rpcgroup_name_list argument is a list of names
of RPC groups to be created. This operation returns an empty string
on success. If the RPC group already exists, an error is returned.
Privileges Required [Toc] [Back]
You need i (insert) permission to the parent directory.
Examples [Toc] [Back]
The following command creates a new group called
/.:/LandS/anthro/Calendar_group:
dcecp> rpcgroup create /.:/LandS/anthro/Calendar_group
dcecp>
rpcgroup delete
Removes the specified group from CDS. The syntax is as follows:
rpcgroup delete rpcgroup_name_list
The delete operation removes the specified group entry from CDS. The
rpcgroup_name_list argument is a list of names of RPC group entries to
be deleted. This operation returns an empty string on success. If the
RPC group entry does not exist, an error is generated.
Privileges Required [Toc] [Back]
Hewlett-Packard Company - 3 OSF DCE 1.1/HP DCE 1.8 PHSS_26394-96
rpcgroup(1m) Open Software Foundation rpcgroup(1m)
You need w (write) permission to the CDS object entry (the target
group entry).
Examples [Toc] [Back]
The following command removes the group
/.:/LandS/anthro/Calendar_group from CDS.
dcecp> rpcgroup delete /.:/LandS/anthro/Calendar_group
dcecp>
rpcgroup help
Returns help information about the rpcgroup object and its operations.
The syntax is as follows:
rpcgroup help [operation | -verbose]
Options [Toc] [Back]
-verbose Displays information about the rpcgroup object.
Used without an argument or option, the rpcgroup help command returns
brief information about each rpcgroup operation. The optional
operation argument is the name of an operation about which you want
detailed information. Alternatively, you can use the -verbose option
for more detailed information about the rpcgroup object itself.
Privileges Required [Toc] [Back]
No special privileges are needed to use the rpcgroup help command.
Examples [Toc] [Back]
dcecp> rpcgroup help
add Adds members to a list of RPC groups.
create Creates a list of empty RPC groups.
delete Deletes a list of RPC groups.
import Returns the bindings from a list of RPC groups.
list Returns the members of a list of RPC groups.
remove Removes members from a list of RPC groups.
help Prints a summary of command-line options.
operations Returns a list of the valid operations for this command.
dcecp>
rpcgroup import
Returns a string binding from the specified RPC group. The syntax is
as follows:
Hewlett-Packard Company - 4 OSF DCE 1.1/HP DCE 1.8 PHSS_26394-96
rpcgroup(1m) Open Software Foundation rpcgroup(1m)
rpcgroup import rpcgroup_name_list -interface interface_id
[-object object_uuid] [-max integer] [-noupdate]
Options [Toc] [Back]
-interface interface_id
Declares the interface identifier of a single RPC interface.
See DATA STRUCTURES for the format of an interface
identifier.
-object object_uuid
Declares the UUID of an object. The UUID is a hexadecimal
string.
See DATA STRUCTURES for the format of an object UUID.
-max integer
Specifies the maximum number of string bindings to return.
A value greater than one returns a list containing up to the
number of bindings specified by the value.
-noupdate Normally, name service data is cached locally on each
machine in a cell. If a name service inquiry can be
satisfied by data in the local CDS cache, this cached data
is returned. However, locally cached copies of name service
data might not include a recent CDS update. If the -noupdate
option is not specified, dcecp goes to one or more CDS
servers to retrieve the required data, updating the local
CDS cache. Use the -noupdate option to avoid taking the
time to update the local cache when you have reason to
believe that the local cache is up to date.
The import operation returns a string binding from the specified RPC
group. The rpcgroup_name_list argument is a list of names of RPC
groups to import from. The operation uses the -interface and -object
options to specify matching bindings. The operation also accepts the
-max option to specify a number of string bindings to return. The
order of bindings returned is arbitrary.
Privileges Required [Toc] [Back]
You need r (read) permission to the specified CDS object entry (the
starting name service entry) and to any CDS object entry in the
resulting search path.
Examples [Toc] [Back]
Hewlett-Packard Company - 5 OSF DCE 1.1/HP DCE 1.8 PHSS_26394-96
rpcgroup(1m) Open Software Foundation rpcgroup(1m)
The following command imports a binding:

rpcgroup list
Returns a list of the names of all members of the specified group. The
syntax is as follows:
rpcgroup list rpcgroup_name_list [-member member_name_list]
[-noupdate]
Options [Toc] [Back]
-member member_name_list
Specifies a list of names of one or more members to be
returned from all groups named in the rpcgroup_name_list
argument. Use this option to check for specific member
names. The member_name_list argument specifies a list of
names of RPC entries, RPC groups, or RPC profiles; they are
only references stored in the RPC group and do not have to
exist outside of the group. All members specified are
listed from all RPC groups specified in the argument.
-noupdate Use -noupdate to avoid taking the time to update the local
cache.
See rpcgroup import for more information.
The list operation returns a list of the names of all members of the
specified group. The names returned are fully qualified and are
returned in an arbitrary order. The rpcgroup_name_list argument is a
list of names of RPC groups whose members' names are to be returned.
Privileges Required [Toc] [Back]
You need r (read) permission to the CDS object entry (the target group
entry).
Examples [Toc] [Back]
The following example lists all the members of the group
/.:/subsys/applications/infobases, in the order in which they were
added to the group:

-member member_name_list
This required option lets you specify a list of names of one
or more members to be removed from all groups named in the
rpcgroup_name_list argument. The member_name_list argument
specifies a list of names of RPC entries, RPC groups, or RPC
profiles; these are only references stored in the RPC group
and need not exist outside of the group. All members
specified are removed from all RPC groups specified in the
argument.
The remove operation removes one or more members from the specified
group. The rpcgroup_name_list argument is a list of names of RPC
groups from which to have members removed. The value of the required
-member option is a list of names of RPC entries, RPC groups, or RPC
profiles. If a specified member does not exist in an RPC group, an
error is returned. This operation returns an empty string on success.
Privileges Required [Toc] [Back]
You need r (read) permission and w (write) permission to the CDS
object entry (the target group entry).
Examples [Toc] [Back]
The following command removes the member
/.:/subsys/applications/video_server from the RPC group
/.:/subsys/applications/infobases:
