The Dnpattern Distribution Partition defines a partition for a DN pattern distribution algorithm.
A partition for a DN pattern distribution algorithm is defined by a string pattern (using a Java Pattern class syntax). A partition can handle a request when the relative part of request base DN matches the string pattern.
The Dnpattern Distribution Partition component inherits from the Distribution Partition

| Description | The DN pattern the relative part of the request base DN must match. The DN pattern is a string pattern whose syntax complies with the Java Pattern class syntax. The string pattern is checked against the relative part of the request base DN only. For example, if the distribution base DN is [ou=people,dc=example,dc=com] then the check of a request base DN [uid=10,ou=people,dc=example,dc=com] would be performed on the RDN [ui=10]. |

| Description | The negative match flag indicates how to use the DN pattern. When the negative match flag is set to true, then the partition is candidate to handle a request when the DN pattern does not match the relative part of the request base DN. By default, the negative match flag is set to false. |

| Description | Identifies the partition. The partition identifier is unique for a given data partition. The identifier is an integer. |

| Description | The criticality determines whether a partition must be up, or if it is acceptable to have it down during search operations. This parameter is meaningful only for search requests. If the partition's workflow element is fully saturated, the behavior is based on the criticality parameter: - TRUE: the partition is critical, the search operation is stopped and an UNAVAILABLE result code is returned to the client. - PARTIAL: the partition is partially critical, the search operation continues with other partitions involved in the search. The entries which are retrieved from healthy partitions are returned to the client. A result code of ADMIN_LIMIT_EXCEEDED is returned to the client, which indicates that the entries returned may be incomplete because one or more partitions are fully saturated. - FALSE: the partition is not critical, the search operation continues with other partitions involved in the search. The entries which are retrieved from healthy partitions are returned to the client. No special result code is returned to the client. |
|---|---|
| Default Value | true |
| Allowed Values | false - The partition is not critical. partial - The partition is partially critical. true - The partition is critical. |
