The Oracle Database Network Service development group is pleased to make two new technical whitepapers available from the Net Services Overview page:
Easy Connect Plus is an enhancement to Oracle's Easy Connect connection syntax. The new syntax is available in Oracle Database drivers (JDBC, ODP.Net, cx_Oracle, node-oracledb etc) and tools that use Oracle Client 19c and connect to Oracle Database 11.2 or later.
Easy Connect syntax has evolved with successive releases of Oracle Database. Easy Connect Plus is its biggest enhancement, making it easy to do more network configuration in-line, without needing tnsnames.ora or sqlnet.ora files. For example, you could connect with "mydbmachine.example.com/orclpdb1?expire_time=2" to to send packets every two minutes. This gives dead server detection and stops connections being closed prematurely by firewalls.
Check the whitepaper for more options and examples.
Oracle Connection Manager (CMAN) is a transparent proxy through which a client connection request is routed to the next hop.
The new whitepaper discusses how to use CMAN to do protocol switching, such as betwen TCP and TCPS, or between IPv4 and IPv6 networks.
