Creating and Using Extended Registry Attributes
testset Is the permission set to test instances of the attribute.
deleteset Is the permission to delete instances of the attribute.
To enter a permission set with more than one permission, concatenate the permissions;
for example, to enter the permissions t, M, and d, enter tMd.
Enclose each ACL manger type’s information in braces and leave a space between each
item (except, of course, between items in the concatenated permission sets).
For example, consider the following command to define an addition ACL Manager for
the MVS_name attribute:
dcecp> xattrschema modify /.:/sec/xattrschema/MVS_name \
-aclmgr {18dbdad2-23df-11cd-82d4-080009251352 r w t mD}
The command adds an ACL manager identified by the UUID 18dbdad2-23df-11cd-
82d4-08000925135 to the MVS_name attribute. The permissions sets for the ACL
manager are as follows:
• r is the query permission set
• w is the update permission set
• t is the test permission set
• mD is the delete permission set
Note that you cannot modify or delete an attribute type’s ACL manager set. However,
you can add additional manager types to it.
32.2.6 Defining Attribute Type Encoding
You must define the format of values that can be supplied for an attribute type in the
attribute type’s encoding. An attribute can be assigned only those values that are in the
format defined in the encoding. For example, the encoding can specify that instances of
this attribute type contain values only in the form of UUIDs.
Each attribute type can have only one encoding and that encoding cannot be modified.
In addition, a special encoding type lets you create attribute sets.
Use the dcecp xattrschema -encoding option to specify an attribute’s encoding. This
option has the following form:
-encoding type
The type parameter is one of the encoding types described in Table 32-2.
