Db2 High Availability Instance Configuration Utility (db2haicu) input file XML schema definition

DB2ClusterType

The root element of the db2haicu XML schema definition (XSD) is DB2Cluster, which is of type DB2ClusterType. A db2haicu XML input file must begin with a DB2Cluster element.

Subelements

DB2ClusterTemplate

Type:

DB2ClusterTemplateType

Usage notes:

Do not include a DB2ClusterTemplateType element in your db2haicu XML input file. The DB2ClusterTemplateType element is currently reserved for future use.

ClusterDomain

Type:

ClusterDomainType

A ClusterDomainType element contains specifications about: the machines or computers in the cluster domain (also called cluster domain nodes); the network equivalencies (groups of networks that can fail over for one another); and the quorum device (tie-breaking mechanism).

Occurrence rules:

You must include one or more ClusterDomain element in your DB2ClusterType element.

FailoverPolicy

Type:

FailoverPolicyType

A FailoverPolicyType element specifies the failover policy that the cluster manager should use with the cluster domain.

Occurrence rules:

You can include zero or one FailoverPolicy element in your DB2ClusterType element.

DB2PartitionSet

Type:

DB2PartitionSetType

A DB2PartitionSetType element contains information about database partitions. The DB2PartitionSetType element is only applicable in a partitioned database environment.

Occurrence rules:

You can include zero or more DB2PartitionSet elements in your DB2ClusterType element, according to the db2haicu db2haicu XML schema definition.

HADRDBSet

Type:

HADRDBType

A HADRDBType element contains a list of High Availability Disaster Recovery (HADR) primary and standby database pairs.

Occurrence rules:

You can include zero or more HADRDBSet elements in your DB2ClusterType element, according to the db2haicu db2haicu XML schema definition.

Usage notes:

• You must not include HADRDBSet in a partitioned database environment.
• If you include HADRDBSet, then you must specify a failover policy of HADRFailover in the FailoverPolicy element.

HADBSet

Type:

HADBType

A HADBType element contains a list of databases to include in the cluster domain, and to make highly available.

Occurrence rules:

You can include zero or more HADBSet elements in your DB2ClusterType element, according to the db2haicu db2haicu XML schema definition.

Attributes

clusterManagerName (optional)

The clusterManagerName attribute specifies the cluster manager.

Valid values for this attribute are specified in the following table:

Table 1. Valid values for the clusterManager attribute

clusterManagerName value	Cluster manager product
TSA	IBM® Tivoli® System Automation for Multiplatforms (SA MP)

Usage notes

In a single partition database environment, you will usually only create a single cluster domain for each database manager instance.
