Description

Alters a semantic network index on a model.

Parameters

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

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 model named family.

EXECUTE SEM_APIS.ALTER_SEM_INDEX_ON_MODEL('family', 'pscm', 'rebuild');
