Creating and Using Extended Registry Attributes

dcecp> principal modify delores -add {MVSname admin}

To add instances of a multivalued extended attribute, include each value, separated by a

space after the attribute name. For example, to attach the multi_name attribute with

values of value1, value2, value3, and value4 to the principal named delores, use the

following command:

dcecp> principal modify delores -add {multi_name value1 value2 \

value3 value4}

32.4.2 Modifying Attribute Instances

Use the dcecp modify -change operation to change the values of attribute instances.

Whether an attribute is modiﬁable is determined by the application that uses the

attribute. For example, the following command changes the value assigned to the

MVSname from admin to cell_admin for the principal named delores.

dcecp> principal modify delores -change {MVSname cell_admin}

If you use the dcecp modify -change command as shown in the previous paragraphs to

change the value of a multivalued attribute, all instances of the multivalued attribute are

deleted and replaced by the new values speciﬁed in the command. For example, to

change only a speciﬁc value, you must enter all the values. For example, assume that the

multi_name attribute has the following four values: value1, value2, value3, and

value4. To change value4 to value5 you must enter the following command:

dcecp> principal modify delores -change {multi_name {value1 value2 \

value3 value5}}

However, you can add and remove individual values from a multivalued attribute. Use

the -add option to add values. For example, assume that the multi_name attribute has

values of value1, value2,value3, and value5. The following sample command adds

value6 to the multi_name attribute.

dcecp> principal modify delores -add {multi_name value6}

(Use the remove option described in the following subsection to delete speciﬁc values

in a multivalued attribute.)

Note that the following command replaces all instances of the attribute named

multi_name attached to the principal named delores with a single instance with a

value of value1:

dcecp> principal modify delores -change {multi_name value1}

For example, if the multi_name attribute had the following values:

{multi_name value1 value2 value3}
