Deprecated Features

Review the deprecated features in Oracle Graph Server and Client.

• Creating Graphs Using Property Graph Schema

  Creating a property graph in the database Using the Property Graph Schema is deprecated. Instead, you can create SQL Property Graphs or PGQL Property Graphs.

• GraphServer#getInstance API

  The following GraphServer#getInstance APIs are deprecated:

  • GraphServer.getInstance(ClientConfig clientConfig, String username, char[] password, int refreshTimeBeforeTokenExpiry)
  • GraphServer.getInstance(String baseUrl, String username, char[] password, int refreshTimeBeforeTokenExpiry)
  • GraphServer.getInstance(String baseUrl, String kerberosTicketPath, int refreshTimeBeforeTokenExpiry)

  Instead, configure the refresh_time_before_token_expiry_seconds parameter in the pgx.conf file.

• opg_apis.get_version()

  The OPG_APIS.GET_VERSION() function is deprecated and will be desupported in a future release. Instead, use OPG_APIS.GET_OPG_VERSION.

• Methods deprecated for PgqlViewGraphExpander

  PgqlViewGraphExpander.schema(String) and PgqlViewGraphExpander.owner(String) are deprecated. Instead, use PgqlViewGraphExpander.fromPgView(String, String).

• Graph Server (PGX) Configuration Fields

  The graph server configuration fields, server_cert and server_private_key are deprecated. Instead, use server_keystore.

• PyPGX
  • The following attributes on Operation are now deprecated: graph_id, operation_type, cost_estimate, total_cost_estimate, cardinality_estimate, pattern_info, and children. Instead, use the corresponding getter methods, such as get_graph_id(), get_operation_type(), and so on.
  • The pgx_version attribute in ServerInstance class is deprecated. Instead, use get_version().
  • The attribute pg_view_name in PartitionedGraphConfig is deprecated. Instead, use source_name and source_type (set to pg_view).
  • set_standarize in GraphWiseModelConfig is deprecated. Instead, use set_standardize.
  • The return value of PgqlResultSet.get_vertex_labels may or may not be a list.
• Subgraph Loading

  Creating Subgraphs using filter expressions is deprecated. Instead, use Loading a Subgraph from a PGQL Property Graph.

• PgxML: inferAndGetExplanation Function

  GraphWiseModel.inferAndGetExplanation() is deprecated. Instead, use GraphWiseModel.gnnExplainer() to obtain a GnnExplainer object for the model and use GnnExplainer.inferAndExplain().

• Pg2vecModelBuilder.setUseGraphletSize(java.lang.Boolean useGraphletSize) method in oracle.pgx.api.mllib API is deprecated. Instead, use the Pg2vecModelBuilder.setUseGraphletSize(boolean useGraphletSize) method.
• PgxML: SupervisedGraphWiseModelBuilder.setLossFunction Function

  SupervisedGraphWiseModelBuilder.setLossFunction(SupervisedGraphWiseModelConfig.LossFunction ...) is deprecated. Instead, use SupervisedGraphWiseModelBuilder.setLossFunction(LossFunction ...) function.

• PL/SQL API OPG_APIS.GET_SCN Function
  The PL/SQL API OPG_APIS.GET_SCN function is deprecated. Instead, to retrieve the current SCN (system change number), use the DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER function:

  SELECT dbms_flashback.get_system_change_number FROM DUAL;
