Example dnaNextRange: 100-500

3.7 .5. dnaNextValue

This attribute gives the next available number which can be assigned. After being initially set in the

configuration entry, this attribute is managed by the Distributed Numeric Assignment Plug-in.

The dnaNextValue attribute is required to set up distributed numeric assignment for an attribute.

Parameter Descript ion

Entry DN cn=Distributed Numeric Assignment Plugin,

cn=plugins, cn=config

Valid Range 1 to the maximum 32-bit integer on 32-bit systems

and to the maximum 64-bit integer on 64-bit

systems

Default Value -1

Syntax Integer

Example dnaNextValue: 1

3.7 .6. dnaPrefix

This attributes defines a prefix that can be prepended to the generated number values for the attribute.

For example, to generate a user ID such as user1000, the dnaPrefix setting would be user.

Parameter Descript ion

Entry DN cn=Distributed Numeric Assignment Plugin,

cn=plugins, cn=config

Valid Range Any string

Default Value None

Syntax DirectoryString

Example dnaPrefix: id

3.7 .7. dnaRangeRequest T imeout

One potential situation with the Distributed Numeric Assignment Plug-in is that one server begins to run

out of numbers to assign. T he dnaThreshold attribute sets a threshold of available numbers in the

range, so that the server can request an additional range from the other servers before it is unable to

perform number assignments.

The dnaRangeRequestTimeout attribute sets a timeout period, in seconds, for range requests so that

the server does not stall waiting on a new range from one server and can request a range from a new

server.

For range requests to be performed, the dnaSharedCfgDN attribute must be set.

Parameter Descript ion

Entry DN cn=Distributed Numeric Assignment Plugin,

cn=plugins, cn=config

Valid Range 1 to the maximum 32-bit integer on 32-bit systems

and to the maximum 64-bit integer on 64-bit

systems

Default Value 10

Syntax Integer

Example dnaRangeRequestT imeout: 15

3.7 .8. dnaScope

This attribute sets the base DN to search for entries to which to apply the distributed numeric

assignment. This is analogous to the base DN in an ldapsearch.

Parameter Descript ion

Entry DN cn=Distributed Numeric Assignment Plugin,

cn=plugins, cn=config

Valid Range Any Directory Server entry

Default Value None

Syntax DirectoryString

Example dnaScope: ou=people,dc=example,dc=com
