Using Advanced Options When Creating a New Property Graph in Oracle Database

For property graph users that know Oracle Database well, you likely know it already that the PL/SQL API, opg_apis.create_pg, offers an options parameter. One of the supported option is "INMEMORY=T" which leverages the Database In-Memory feature.  A question arises then, can we use this option from Java or via the graph config? The answer is yes to both. To create a new property graph with an advanced option, the following static Java method (part of...

Using SSD to Speed up Property Graph Operations in Oracle Database (I)

First of all, Happy New Year!  At the end of last year, I got a question on property graph data loading performance in Oracle Database. After a while, I realized the performance issue was most likely caused by the database setup: a single SATA disk used in a VM. The IO performance was obviously poor in the setup. To illustrate the importance of a sufficiently fast storage to an Oracle Database, I did an experiment using an old commodity server setup which has 64 GB RAM and 2...

Four Quick Steps to Use a HTTPS (SSL) based PGX Service Endpoint

In the past, I have shown many examples on connecting a client to a remote PGX service endpoint. For simplicity, the endpoint used was HTTP based. In practice, one may want to use HTTPS (SSL) based endpoint for better security. Given the most recent Equifax security breach, who wouldn't use better security?! If the SSL-enabled endpoint is using a self-signed certificate, then you will most likely see this error "unable to find valid certification path to requested target". In...
