Oracle port 1521 TCP or UDP
[ Home | TCP/IP Ports | Contact Me ] Show This is a sub-page of my main TCP/IP ports page. I have separated Oracle out because it uses such a large number of ports. Oracle Ports for Network Services
Although incomplete, this is a pretty good article on the mess that is Oracle ports: Connecting with Oracle: Oracle Ports. I also got some information from these copies of Oracle documentation Oracle9i Net Services Reference Guide Release 2 (9.2) and Oracle Database Net Services Reference Guide 10g Release 1 (10.1) The Oracle Technology Network (OTN) should provide all the information you need, but I find it difficult to locate things there. 9iAS is a port nightmare. A typical install may have dozens of ports open. Many of the ports are not IANA-registered. The document Oracle® Collaboration Suite Installation and Configuration Guide Release 2 Default Port Numbers and Port Ranges was the best reference I could find to the many many Oracle ports used. I have only listed the HTTP parts in the table below.
SummaryFor the HTTP web server bits, Oracle likes to use 7777, 7778 and 7779. For SSL ("secure" encrypted communications, you may know it as HTTPs) they like to use 4443, 4444, 4445, 4446. These ports are already IANA assigned for other things. An important security point that you should be aware of is that by default Oracle will create a helpful Ports page on your 9iAS server, listing all the ports it has assigned for everything. The URL will be /portlist Locally on your system, there will also be a file $ORACLE_HOME/install/portlist.ini listing all the port assignments made. I link to the IANA list on my main TCP/IP ports page. Copyright © 2004-2005 Richard Akerman. All rights reserved. No mirroring without prior written consent.

[ Home | TCP/IP Ports | Contact Me ] Does Oracle use TCP or UDP?UDP is available on Linux, AIX, Solaris and HP/UX, and other OS platforms. Overall, the vast majority of Oracle databases use TCP/IP, because UDP does not have built-in hand-shake dialogues. This means that UDP does not have the same data integrity and reliability and serialization as TCP/IP.
What protocol is 1521?Port 1521 Details. Does Oracle use TCP?The TCP/IP with Secure Sockets Layer (SSL) protocol enables an Oracle application on a client to communicate with remote databases through TCP/IP and SSL. Oracle Advanced Security is required to use TCP/IP with SSL.
Why is port 1521 used?Side note: TCP port 1521 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data.
