Description

Alters an RDF network index on an inferred graph.

Parameters

inferred_graph_name: Name of the inferred graph.
index_code: Index code string.
command: String value containing one of the following commands: REBUILD rebuilds the RDF network index on the inferred graph, or UNUSABLE marks as unusable the RDF network index on the inferred graph. 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 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 RDF network. (See Table 1-2.)
network_name: Name of the RDF network. (See Table 1-2.)

Usage Notes

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

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

Examples

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

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