• 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.

  • 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(...).
