 DESCRIPTION    [Toc]    [Back]
      The nistbladm command is used to administer NIS+ tables.  There are
      five primary operations that it performs: creating and deleting
      tables, adding entries to, modifying entries within, and removing
      entries from tables.

      Though NIS+ does not place restrictions on the size of tables or
      entries, the size of data has an impact on the performance and the
      disk space requirements of the NIS+ server.  NIS+ is not designed to
      store huge pieces of data, such as files; instead pointers to files
      should be stored in NIS+.

      NIS+ design is optimized to support 10,000 objects with a total size
      of 10M bytes.  If the requirements exceed the above, it is suggested
      that a domain hierarchy be created, or the data stored in the tables
      be pointers to the actual data, instead of the data itself.

      When creating tables, a table type, type, and a list of column
      definitions must be provided.

      type is a string that is stored in the table and later used by the
      service to verify that entries being added to it are of the correct
      type.

      Syntax for column definitions is:

 nistbladm(1)                                                   nistbladm(1)




           colname=[flags][,access]

      flags is a combination of:

           S       Searchable. Specifies that searches can be done on the
                   column's values (see nismatch(1)).
           I       Case-insensitive (only makes sense in combination with
                   S).  Specifies that searches should ignore case.
           C       Crypt.  Specifies that the column's values should be
                   encrypted.
           B       Binary data (does not make sense in combination with S).
                   If not set, the column's values are expected to be null
                   terminated ASCII strings.
           X       XDR encoded data (only makes sense in combination with
                   B).

      access is specified in the format as defined by the nischmod(1)
      command.

      When manipulating entries, this command takes two forms of entry name.
      The first uses a series of space separated colname=value pairs that
      specify column values in the entry.  The second is an NIS+ indexed
      name, indexedname, of the form:

           [ colname=value, ... ],tablename

    Options    [Toc]    [Back]
           -a | A         Add entries to a NIS+ table.  The difference
                          between the lowercase `a' and the uppercase `A' is
                          in the treatment of preexisting entries.  The
                          entry's contents are specified by the column=value
                          pairs on the command line.  Note:  Values for all
                          columns must be specified when adding entries to a
                          table.

                          Normally, NIS+ reports an error if an attempt is
                          made to add an entry to a table that would
                          overwrite an entry that already exists.  This
                          prevents multiple parties from adding duplicate
                          entries and having one of them get overwritten.
                          If you wish to force the add, the uppercase `A'
                          specifies that the entry is to be added, even if
                          it already exists.  This is analogous to a modify
                          operation on the entry.

           -c             Create a table named tablename in the namespace.
                          The table that is created must have at least one
                          column and at least one column must be searchable.

           -d tablename   Destroy the table named tablename.  The table that
                          is being destroyed must be empty.  The table's

 nistbladm(1)                                                   nistbladm(1)




                          contents can be deleted with the -R option below.

           -e|E           Edit the entry in the table that is specified by
                          indexdname.  indexdname must uniquely identify a
                          single entry.  It is possible to edit the value in
                          a column that would change the indexed name of an
                          entry.

                          The change (colname=value) may affect other
                          entries in the table if the change results in an
                          entry whose indexed name is different from
                          indexedname and which matches that of another
                          existing entry.  In this case, the -e option will
                          fail and an error will be reported.  The -E option
                          will force the replacement of the existing entry
                          by the new entry (effectively removing two old
                          entries and adding a new one).

           -m             Modify an entry in the table that is specified by
                          indexedname.  Note:  Since it is possible to
                          modify the value in a column that would change the
                          indexed name for an entry, both the column value
                          pair and the indexed name are required. It uses
                          the indexed name to look up the entry, modify it,
                          and write it back with the new value.  The indexed
                          name must uniquely identify a single entry.

           -r|R           Remove entries from a table. The entry is
                          specified by either a series of column=value pairs
                          on the command line, or an indexed name that is
                          specified as entryname.  The difference between
                          the interpretation of the lowercase r versus the
                          uppercase R is in the treatment of non-unique
                          entry specifications.  Normally the NIS+ server
                          will disallow an attempt to remove an entry when
                          the search criterion specified for that entry
                          resolves to more than one entry in the table.
                          However, it is sometimes desirable to remove more
                          than one entry, as when you are attempting to
                          remove all of the entries from a table.  In this
                          case, using the uppercase R will force the NIS+
                          server to remove all entries matching the passed
                          search criterion.  If that criterion is null and
                          no column values specified, then all entries in
                          the table will be removed.

           -u             Update attributes of a table.  This allows the
                          concatenation path (-p), separation character
                          (specified with the (-s)), column access rights,
                          and table type string (-t) of a table to be
                          changed.  Neither the number of columns, nor the

 nistbladm(1)                                                   nistbladm(1)




                          columns that are searchable may be changed.

           -D defaults    When creating objects, this option specifies a
                          different set of defaults to be used during this
                          operation.  The defaults string is a series of
                          tokens separated by colons.  These tokens
                          represent the default values to be used for the
                          generic object properties.  All of the legal
                          tokens are described below.

                          ttl=time  This token sets the default time to live
                                    for objects that are created by this
                                    command. The value time is specified in
                                    the format as defined by the nischttl(1)
                                    command.  The default value is 12 hours.

                          owner=ownername
                                    This token specifies that the NIS+
                                    principal ownername should own the
                                    created object.  Normally this value is
                                    the same as the principal who is
                                    executing the command.

                          group=groupname
                                    This token specifies that the group
                                    groupname should be the group owner for
                                    the object that is created. The default
                                    value is NULL.

                          access=rights
                                    This token specifies the set of access
                                    rights to be granted for the given
                                    object.  The value rights is specified
                                    in the format as defined by the
                                    nischmod(1) command.  The default value
                                    is ----rmcdr---r---.

           -p path        When creating or updating a table, this option
                          specifies the table's search path. When an
                          nis_list() function is invoked, the user can
                          specify the flag FOLLOW_PATH to tell the client
                          library to continue searching tables in the
                          table's path if the search criteria used does not
                          yield any entries. The path consists of an ordered
                          list of table names, separated by colons.  The
                          names in the path must be fully qualified.

           -s sep         When creating or updating a table, this option
                          specifies the table's separator character.  The
                          separator character is used by niscat(1) when
                          displaying tables on the standard output.  Its

                          purpose is to separate column data when the table
                          is in ASCII form.  The default value is a space.

           -t type        When updating a table, this option specifies the
                          table's type string.

 RETURN VALUE    [Toc]    [Back]
      This example returns 0 on success and 1 on failure.

 EXAMPLES    [Toc]    [Back]
      Create a table named hobbies in the directory foo.com.  of the type
      hobby_tbl with two searchable columns, name and hobby:

           nistbladm -c hobby_tbl name=S,a+r,o+m hobby=S,a+r
                    hobbies.foo.com.

      The column name has read access for all (that is, owner, group, and
      world) and modify access for only the owner.  The column hobby is
      readable by all, but not modifiable by anyone.

      In this example, if the access rights had not been specified, the
      tables access rights would have come from either the standard defaults
      or the NIS_DEFAULTS variable (see below).

      Add entries to this table:

           nistbladm -a name=bob hobby=skiing hobbies.foo.com.
           nistbladm -a name=sue hobby=skiing hobbies.foo.com.
           nistbladm -a name=ted hobby=swimming hobbies.foo.com.

      Add the concatenation path:

           nistbladm -u -p hobbies.bar.com.:hobbies.baz.com. hobbies

      Delete the skiers from our list:

           nistbladm -R hobby=skiing hobbies.foo.com.

      Note:  The use of the -r option would fail because there are two
      entries with the value of skiing.

      To create a table with a column that is named with no flags set, you
      supply only the name and the equal sign (=) as follows:

           nistbladm -c notes_tbl name=S,a+r,o+m note=  notes.foo.com.

      This example created a table, named notes.foo.com.,oftype notes_tbl
      with two columns name and note.  The note column is not searchable.

      When entering data for columns in the form of a value string, it is
      essential that terminal characters be protected by single or double



 Hewlett-Packard Company            - 5 -   HP-UX 11i Version 2: August 2003






 nistbladm(1)                                                   nistbladm(1)




      quotes. These are the characters equals (=), comma (,), left bracket
      ([), right bracket (]), and space ( ).  These characters are parsed by
      NIS+ within an indexed name.  These characters are protected by
      enclosing the entire value in double quote (") characters as follows:

           nistbladm -a fullname="Joe User" nickname=Joe nicknames

      If there is any doubt about how the string will be parsed, it is
      better to enclose it in quotes.

 EXTERNAL INFLUENCES    [Toc]    [Back]
    Environment Variables
      NIS_DEFAULTS      This variable contains a defaults string that will
                        override the NIS+ standard defaults.  If the -D
                        switch is used, those values will then override both
                        the NIS_DEFAULTS variable and the standard defaults.

      NIS_PATH          If this variable is set and the NIS+ table name is
                        not fully qualified, each directory specified will
                        be searched until the table is found (see
                        nisdefaults(1)).

 WARNINGS    [Toc]    [Back]
      To modify one of the entries, say, for example, from bob to robert:

           nistbladm -m name=robert [name=bob],hobbies

      Note that [name=bob],hobbies is an indexed name, and that the
      characters `[' (open bracket) and `]' (close bracket) are interpreted
      by the shell.  When typing entry names in the form of NIS+ indexed
      names, the name must be protected by using single quotes.

      It is possible to specify a set of defaults such that you cannot read
      or modify the table object later.

      HP-UX 11i Version 2 is the last HP-UX release on which NIS+ is
      supported.

      LDAP is the recommended replacement for NIS+.  HP fully supports the
      industry standard naming services based on LDAP.
