15.83 SEM_APIS.ENABLE_INMEMORY

Format

SEM_APIS.ENABLE_INMEMORY(
     populate_wait IN BOOLEAN,
     options       IN VARCHAR2 DEFAULT NULL,
     network_owner IN VARCHAR2 DEFAULT NULL,
     network_name  IN VARCHAR2 DEFAULT NULL);

Description

Loads RDF data for the semantic network into memory.

Parameters

populate_wait

Boolean value to indicate whether to wait until all RDF data is loaded into memory before finishing:

• true: Wait until all RDF data is loaded into memory.

• false: Do not wait for RDF data loading into memory.

options

Options for in-memory data population:

• The string POPULATE_TRIPLES=F disables populating RDF_LINK$ table data in memory. (RDF_VALUE$ table data is still populated in memory.) If this option is not specified, RDF_LINK$ table data is populated in memory by default.

network_owner

Owner of the semantic network. (See Table 1-2.)

network_name

Name of the semantic network. (See Table 1-2.)

Usage Notes

To use this procedure, you must have DBA privileges.

See the information in RDF Support for Oracle Database In-Memory.

To disable in-memory population of RDF data in the semantic network, use the SEM_APIS.DISABLE_INMEMORY.

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

Examples

The following example enables in-memory population of RDF data, and waits until all RDF data is loaded into memory before finishing.

EXECUTE SEM_APIS.ENABLE_INMEMORY(true);
