show clerk(1m) show clerk(1m) NAME
show clerk - Displays attribute information about the CDS clerk on the local system SYNOPSIS
cdscp show clerk DESCRIPTION
The show clerk command displays all the names and values of the clerk attributes on the local system. The clerk must be enabled when you use this command. The following are valid attributes: Specifies the number of times a requesting principal failed authentication procedures. Specifies the number of requests to read attributes for which the clerk was specifically directed by the requesting application to bypass its own cache. Instead, a server is contacted to get the requested information. This attribute does not account for requests that the clerk is unable to satisfy from the cache or for requests to look up names or enumerate the contents of directories. Specifies the total number of read requests directed to this clerk that were satisfied entirely by the information contained in its own cache. This attribute accounts only for requests to read attribute values and does not include requests to look up names or enumerate the contents of directories. Specifies the time when this entity was created. Specifies the number of operations other than read and write (that is, skulks, enumerating contents of directories, and so on) performed by this clerk. Specifies the number of lookup operations performed by this clerk. This attribute accounts only for requests to read attributes and does not include requests to look up names or enumerate the contents of directories. Specifies how many requests to modify data were processed by this clerk. Privilege Required You must have read permission to the clerk. NOTE
This command may be replaced in future releases by the dcecp command, and may no longer be supported at that time. EXAMPLE
The following command displays the attributes of the clerk on the local system: cdscp> show clerk SHOW CLERK AT 1991-10-15-15:56:50 Creation Time = 1991-10-15-15:38:19.000000051-04:00I0.000000000 Authentication failures = 0 Read Operations = 1068 Cache Hits = 137 Cache bypasses = 433 Write operations = 1250 Miscellaneous operations = 590 RELATED INFORMATION

With the exception of the following subcommands, this command is replaced at Revision 1.1 by the dcecp command. This command may be fully replaced by the dcecp command in a future release of DCE, and may no longer be supported at that time. disable clerk disable server help set cdscp confidence set directory to new epoch show cdscp confidence show cell show clerk show server DESCRIPTION
The Cell Directory Service (CDS) control program is a command line interface for managing the components of the Cell Directory Service and the contents of the namespace. You can use the control program commands from within the control program or from the system prompt. To use the control program commands from inside the control program, start the control program by using the cdscp command alone, without any argument. This enters the control program, which displays the control program prompt (cdscp>): $ cdscp cdscp> At this prompt, you can enter any control program command; for example: cdscp> show server Use the command do filename from inside the control program to read a file of commands. To leave the control program and return to the system prompt, use the quit command. To use the control program commands from the system prompt, enter the cdscp command with an internal command of the CDS control program as the first argument. The control program executes the command immediately, without displaying the control program prompt. For example, you can enter the show server command as follows: $ cdscp show server Elements of a CDS Command All CDS control program commands must include a verb, an entity name, and all required arguments. Depending on the command, you can also specify optional arguments and attributes. A space must separate more than one attribute or argument. A space must precede and follow an equal sign (=). Verbs The following is a list of the definitions of verbs used in control program commands: Adds a value to a modifiable, set-valued attribute Removes knowledge of a cached clearinghouse or cached server from memory Creates an entity Creates knowledge of a locally cached server Deletes an entity Stops operation of a clerk or server Displays the contents of a clerk cache Displays a list of specified entity names Removes a value from a set-valued or single-valued attribute Changes the value of a modifiable, single-valued attribute Displays attribute information Entity Names Any individually manageable piece of CDS is called an entity. A set of commands exists for each entity. The following is a list of the entities and a description of what each entity represents: A cached clearinghouse is a clearinghouse that a clerk has discovered and cached. A clerk can learn about clearinghouses as a result of configuration information, advertisements received on a LAN, or during the process of finding a name. A cached server is a server that a clerk has cached as a result of manual configuration through the control program. A child pointer connects a parent and child directory in a hierarchical namespace. The child pointer is stored in the parent directory and has the same name as the child directory. A clearinghouse is a database containing a collection of directory replicas at a particular server. The clerk is the interface between client applications and servers. A directory contains child, object, and link entries that are logically stored under one name (the directory name). A soft link is a pointer providing an alternate name for an object entry, directory, or other soft link. An object entry represents a resource (for example, an application) that is named in the namespace. A replica is a copy of a directory. Each copy, including the original or master, is referred to as a replica. A server handles lookup requests from clerks and maintains the contents of the clearinghouse or clearinghouses at its node. Attributes Every CDS entity has attributes, which are pieces or sets of data associated with that entity. Attributes can reflect or affect the opera- tional behavior of an entity, record the number of times a particular event or problem occurred since the entity was last enabled, and uniquely distinguish an entity from any other entity. Some attributes have a single value; others contain a set of values. CDS attributes are identified by ISO object identifiers (OIDs). Every CDS attribute name maps to an OID and a corresponding data type. Usually, client applications define the name of an attribute and its data type. Application programmers should never need to modify (except for the purpose of foreign language translation) the existing CDS labels associated with the unique OIDs in the cds_attributes file. However, programmers can obtain new OIDs from the appropriate allocation authority, create new attributes for their own object entries, and then append them to the existing list. The OID and data type of each attribute are stored in the file /opt/dcelo- cal/etc/cds_attributes. Descriptions of the CDS data types that applications can use are in the cdsclerk.h file. All entities have show commands that you can use to display the names and values of specific attributes or all attributes. When you dis- play an attribute that has more than one value, the show command lists each value for the attribute separately. When there are multiple values for an attribute, the command first lists the attribute name on a line ending with a colon, then the parts of the value. For more information about CDS attributes, see the DCE Directory Service module in the DCE Administration Guide. Editing the Commands You can abbreviate commands, continue a command beyond one line, or redirect output to a file within the control program. To abbreviate any command name, type only the first four characters. You can abbreviate a command name to fewer than four characters as long as the abbreviated name remains unique among all command names in the control program. For example, the following commands are equiv- alent: cdscp> show directory /.:/sales cdscp> sh dir /.:/sales To continue a long command line onto the next line, type a space and then a (backslash) at the end of the first line, for example: cdscp> set link /.:/sales CDS_LinkTimeout > (1991-12-31-12:00:00 090-00:00:00) To add a comment, use the # (number sign). Everything following the # character on a line is ignored. To redirect output to a file, most UNIX shell users can type >filename at the shell prompt. To redirect output of error text to a file, most UNIX shell users can type >&filename at the shell prompt. For example, the following command redirects the display produced by the show directory command to a new text file named directory_names: $ cdscp show directory /.:/* >directory_names Using Wildcard Characters When entering a name in show and list commands, you can use wildcard characters in the rightmost simple name (the name to the right of the last slash (/) in the full pathname). The asterisk (*) matches 0 or more characters in a simple name. The question mark (?) matches exactly one character in a simple name. When you use an asterisk or a question mark as a normal character in the rightmost simple name of a show or list command, escape it with a backslash (* or ?). Otherwise, the character is interpreted as a wildcard. You cannot use wildcard characters in show clerk and show server commands. Privilege Required CDS supports the following DCE permissions: read (r), write (w), insert (i), delete (d), test (t), control (c), and administer (a). Each permission has a slightly different meaning, depending on the kind of CDS name with which it is associated. In general, the permissions are defined as follows: Allows a principal to look up a name and view the attribute values associated with it. Permission allows a principal to change the modifiable attributes associated with a name, except the name's access control list (ACL) entries. Permission (for use with directory entries only) allows a principal to create new names in a directory. Permission allows a principal to delete a name from the namespace. Permission allows a principal to test whether an attribute of a name has a particular value without being able to actually see any of the values (that is, without having read permission to the name). Test permission provides application programs a more efficient way to verify a CDS attribute value. Rather than reading an entire set of values, an application can test for the presence of a particular value. Permission allows a principal to modify the ACL entries associated with a name. (Note that read permission is also necessary for modifying a CDS entry's ACLs; otherwise, acl_edit will not be able to bind to the entry.) Control permission is automatically granted to the creator of a CDS name. Permission (for use with directory entries only) allows a principal to issue CDS control program commands that control the replication of directories. The creator of a name is automatically granted all permissions appropriate for the type of name created. For example, a principal creating an object entry is granted read, write, delete, test, and control permission to the object entry. A principal creating a directory is granted read, write, insert, delete, test, control, and administer permission to the directory. EXAMPLES
The following command starts the CDS control program: $ cdscp cdscp> The following command operates from the system prompt to display the attributes of the CDS clerk on the local system: $ cdscp show clerk RELATED INFORMATION
