Description

Alters a semantic network index on an entailment.

Parameters

entailment_name

Name of the entailment.

index_code

Index code string.

command

String value containing one of the following commands: REBUILD rebuilds the semantic network index on the entailment, or UNUSABLE marks as unusable the semantic network index on the entailment. The value for this parameter is not case-sensitive.

tablespace_name

Name of the destination tablespace for the rebuild operation.

use_compression

Specifies whether compression should be used when rebuilding the index.

parallel

Degree of parallelism to be associated with the operation. For more information about parallel execution, see Oracle AI Database VLDB and Partitioning Guide.

online

TRUE allows DML operations affecting the index during the rebuilding of the index; FALSE (the default) does not allow DML operations affecting the index during the rebuilding of the index.

options

(Not currently used.)

network_owner

Owner of the semantic network. (See Table: network_owner and network_name Parameters.)

network_name

Name of the semantic network. (See Table: network_owner and network_name Parameters.)

Usage Notes

For an explanation of semantic network indexes, see Using Semantic Network Indexes.

For information about semantic network types and options, see RDF Networks.

Examples

The following example rebuilds (and makes usable if it is unusable) the semantic network index on the entailment named rdfs_rix_family.

EXECUTE SEM_APIS.ALTER_SEM_INDEX_ON_ENTAILMENT('rdfs_rix_family', 'pscm', 'rebuild');
