EASY CONNECT PLUS - EZCONNECT

Oracle Database 19c introduces a significantly enhanced connection string syntax called Easy Connect Plus.

By reducing the need for external configuration files, Easy Connect Plus makes it easier to use features such as TLS connections, wallets, load balancing, connection timeouts, and to tune network buffer sizes.

Easy Connect Plus can be used in JDBC and .NET applications. It is also usable in applications and drivers built on the C language Oracle Call Interface (OCI) such as the Oracle Database drivers for Python, Node.js, PHP, Ruby, and Go.

Easy connect background

An Easy Connect string includes a host name, an optional port, and the database service name:

database_host[:port][/[service_name]

Easy connect plus syntax

The Oracle Database 19c enhanced Easy Connect Plus syntax is a superset of Easy Connect that supports more connection options. The syntax is available in Oracle Database drivers (JDBC, ODP.Net, cx_Oracle, node-oracledb etc) that use Oracle Client 19c and connect to Oracle Database 11.2 or later.
