15.2 Graph Management in the Graph Server (PGX)

You can load a graph into the graph server (PGX) and perform different actions such as publish, store, or delete a graph.

Note:

Ensure that you drop the graph when it is no longer in use to release the graph server (PGX) memory. See Deleting a Graph for more information.

• Reading Graphs from Oracle Database into the Graph Server (PGX)
  Once logged into the graph server (PGX), you can read graphs from the database into the graph server.
• Storing a Graph Snapshot on Disk
  After reading a graph into memory, you can make any changes to the graph (such as running the PageRank algorithm and storing the values as vertex properties), and then store this snapshot of the graph on disk.
• Publishing a Graph
  You can publish a graph that can be referenced by other sessions.
• Deleting a Graph
  In order to reduce the memory usage of the graph server (PGX), the session must drop the unused graph objects created through the getGraph() method, by invoking the close() method.
