7.2 Start the PGX Server

To use OAAgraph package functions with Oracle R Enterprise 1.5.1, follow these instructions to start the PGX server in Oracle Database 12c, Release 2 (12.2).

1. Navigate to the $ORACLE_HOME/md/property_graph/pgx directory.
2. Run the bin/start-server script:
   ./bin/start-server

The server is up and listening on port 7007 after you see a message such as the following:

INFO: Starting ProtocolHandler ["http-nio-7007"]

The launcher script displays a few warning messages that JAR files cannot be found. This is a known issue and the messages can safely be ignored.

Note:

The script does not return by default. To stop the server, press Ctrl —C or close the terminal.
