cn=Component

The cn=Component entry identifies the part of the software being accessed through a service. The following parts of the software are identified by the cn=Component entry:

• Load balancing algorithm

• Connection class

• Data view

Proportional Load Balancing Algorithm For All Data Sources

The cn=Component entry for the proportional load balancing algorithm for all data sources has the following monitoring DN:

cn=ProportionalLB, cn=DataSourcePool poolname, cn=Component, 
  cn=instanceId, cn=Instance, cn=OperatingSystem, cn=Product, cn=monitor

Entries below the cn=Component entry for the proportional load balancing algorithm contain the following groups of attributes for all data sources:

Settings

• Provides configuration attribute values.

State

• enabled identifies the status of the remote SAP. If the value is TRUE, the load balancing algorithm is active.

Statistics

• totalProvidedBindConnections identifies the total number of connections provided for bind operations.

• totalRefusedBindConnections identifies the number of refused connections for bind operations.

  Connections can be refused for one of the following reasons:

  • The pool of data sources is empty.

  • All the data sources in the pool are down.

  • The data source selected by the load balancing algorithm has no free connection to reach the remote service.

• totalProvidedAddConnections see totalProvidedBindConnections

• totalRefusedAddConnections see totalRefusedBindConnections

• totalProvidedCompareConnections see totalProvidedBindConnections

• totalRefusedCompareConnections see totalRefusedBindConnections

• totalProvidedDeleteConnections see totalProvidedBindConnections

• totalRefusedDeleteConnections see totalRefusedBindConnections

• totalProvidedModifyConnections see totalProvidedBindConnections

• totalRefusedModifyConnections see totalRefusedBindConnections

• totalProvidedModifyDNConnections see totalProvidedBindConnections

• totalRefusedModifyDNConnections see totalRefusedBindConnections

• totalProvidedCompareConnections see totalProvidedBindConnections

• totalRefusedCompareConnections see totalRefusedBindConnections

Proportional Load Balancing Algorithm For Individual Data Sources

The cn=Component entry for the proportional load balancing algorithm for individual data sources has the following monitoring DN:

cn=Add, cn=servername, cn=Proportional LB, cn=DataSource Pool poolname,
  cn=Component, cn=instanceId, cn=Instance, cn=OperatingSystem, 
  cn=Product, cn=monitor

Similar monitoring DNs exist for the delete, modify, modifyDN, search, compare, and bind operations.

Entries below the cn=Component entry for the proportional load balancing algorithm contain the following groups of attributes for individual data sources:

Settings

• expectedWeight identifies the expected weight for the operation on the data source.

State

• operationalStatus identifies the status of the element, with the following values: 2, and 5. For information about these values, see Table 18–2.

Statistics

• provided the number of connections provided to reach the data source for the operation.

• failed the number of failed requests to get a connection to that data source.

• realWeight the real usage of the data source for the operation, to be compared with the expectedWeight.
