    • PgxSessionreadGraphFiles(List<String>, List<String>, Format)
    • PgxSessionreadGraphFiles(List<String>, List<String>, Format, String)
  • PgxGraphFromFramesCreator.partitioned(boolean) is desupported.
  • The Graph Visualization application which runs on https://<server_host>:7007/ui/ is desupported. Instead, use the new Graph Visualization application by opening the URL https://<server_host>:7007/dash/ in your browser (see Running the Graph Visualization Web Client).

    Note that accessing the old URL https://<server_host>:7007/ui/ will automatically redirect you to the new URL https://<server_host>:7007/dash/.

  • Oracle Database 12.2 is desupported.
  • The graph server configuration fields, server_cert and server_private_key are desupported. Instead, use server_keystore.
  • The following GraphServer#getInstance APIs are desupported:
    • 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.

  • Oracle JDK 8 is desupported.
  • Oracle Graph HDFS connector is desupported.
  • SupervisedGraphWiseModel.inferAndGetExplanation(...) is desupported. Instead, use SupervisedGraphWiseModel.inferAndExplain(...).
  • UnsupervisedGraphWiseModel.inferAndGetExplanation(...) is desupported. Instead, use UnsupervisedGraphWiseModel.inferAndExplain(PgxGraph, PgxVertex).
  • Pg2vecModelBuilder.setUseGraphletSize(java.lang.Boolean useGraphletSize) method in oracle.pgx.api.mllib API is desupported. Instead, use the Pg2vecModelBuilder.setUseGraphletSize(boolean useGraphletSize) method.
  • AbstractGraphConfigBuilder.setFilter(final GraphFilter filter) is desupported. Instead use Loading a Subgraph from a PGQL Property Graph.
  • AbstractGraphConfigBuilder.setFilterStrategy(final FilterStrategy filterStrategy) is desupported. Instead use Loading a Subgraph from a PGQL Property Graph.
  • GraphConfig.getLoadingFilter() is desupported. Instead use Loading a Subgraph from a PGQL Property Graph.
  • SupervisedGraphWiseModelBuilder.setLossFunction(SupervisedGraphWiseModelConfig.LossFunction ...) is desupported. Instead, use SupervisedGraphWiseModelBuilder.setLossFunction(LossFunction).
  • PgqlViewGraphExpander.schema(String) is desupported. Instead, use PgqlViewGraphExpander.fromPgPgql(String, String).
  • PgqlViewGraphExpander.owner(String) is desupported. Instead, use PgqlViewGraphExpander.fromPgPgql(String, String).
  • The PgxSession.getGraphs() method is desupported. Instead, use PgxSession.getGraphs(Namespace namespace).
  • The PgxSession.getGraphsAsync() method is desupported. Instead, use PgxSession.getGraphsAsync(Namespace namespace).
