Accepts connections on port 1521 (default)

Returns new (dedicated/shared) connection on another port

Does not work with most firewalls Need to “fix” port or use Connection Manager

Protocols Net8 (oci) – “Heavy” e.g. Oracle Tools Thin (JDBC) – Direct TCP/IP

If things failed badly: Uninstall

Run DB Configuration Assistant Delete Database Instance

Run Oracle Installer Select: Deinstall Products

Stop/Kill Services Delete Oracle_Home

Apr-04 Installation Oracle 16

Oracle Uninstall (2) Linux/Unix:

Firewall Issues Standard Listener: Port Switching

Contact Listener on port 1521 Returns a (dedicated) connection on another

Port Options:

Windows USE_SHARED_SOCKET = TRUE

Net8 compliant firewall Connection Manager

Port 1610

Network Performance Issue: High Latency Networks

Ping > 60ms JDBC – about 10-15 round trips Upload Speed of 128k usually sufficient

Options “Create Objects on Server” - Preferences

Option Tunnel via HTTP – Connection Option

JDBC via RMI via HTTP
