Cherie, I summarised the ports used by Oracle for our Network support specialist and have copied it below:
Metalink note 69511.1 refers to SNMP and the Oracle agent - hopefully that document or some of the others listed can help you out. " Oracle & TCP IP Ports - for future reference Oracle uses a number of fixed TCP ports, these include (Metalink note 99721.1 has a more complete list if the ports that Oracle listens on) 1521 / 1526 - used by the Oracle listener as the initial point a client connects to 2481 - the recommended and officially registered listening port for client connections to the Java option using TCP/IP. 2482 - the recommended and officially registered listening port for client connections to the Java option using TCP/IP with SSL. Client Connections xyz - ie arbitrary port In a standard Oracle configuration , when a client connects to the listener, the listener spawns a dedicated connection thread for that client on a dedicated TCP port. >From Metalink note 125021.1, the server port that is assigned to the client is >randomly chosen by the operating system and can't be modified. It can be any free >port available that the server determines is not is use by any other software or >hardware. >From note 66382.1, for the port on the client PC, what happens is that the networking >software on the client chooses at random, or in sequential order, a valid port >(between 1024 and 65535) so the client can send and receive data. (Metalink notes such as 125021.1, 124140.1, 2084440.6 + 66382.1 describe use of Oracle with Firewalls where one option is to force all clients to share the same singular TCP port - other possibilities include using a Firewall that supports SQLNet / Net8 or using Oracle's connection manager program). The following are used for SNMP (Metalink note 69511.1) 161 - the Oracle SNMP Master agent needs to work as the SNMP master agent so it works on default port of 161 and SNMP itself gets moved to another port 8161 - the port we have chosen to move Windows SNMP service to Oracle Enterprise Manager (OEM) ports (from Metalink note 94394.1) 1748 / 1754 - Used under full control by the Oracle Intelligent agent (process that schedules jobs and monitoring events) These ports are used during the discovery process of Oracle services - 1748 is used for basic communication and 1754 is used for file transfer 7771 - The OEM client tools use this to talk to the Oracle Management Service (OMS) processes. 7772 - The Oracle intelligent agent (IA) uses this to talk to the OMS 7773 - used as a SSL channel to transfer information from the Intelligent Agent to Enterprise Manager framework 1808 - Tools which communicate with the Oracle Data Gatherer use this port for basic communication 1809 - is also used for SSL communication between the client application and the Data Gatherer. xyz - ie arbitrary port based on availability - Communication from the Data Gatherer back to the Capacity planner is done via a callback mechanism. Capacity Planner will initiate a communication via 1808, and the Data Gatherer will initiate the response back via an arbitrary port, based on availability. " HTH, Bruce Reardon -----Original Message----- Sent: Tuesday, 16 July 2002 2:49 We have a third-party application that needs to use the SNMP agent associated with OEM. They want to be able to get to it via a particular port. We have a port assigned to each database, based on which Oracle version it is running. However, as far as I know, there is not a particular port number associated with the OEM agent. The only way you can designate a particular port number is by going through a particular database. Is this correct. I looked through the 9.0.1 Installing the Instelligent Agent manual and I don't see any place where it states how you can associate the OEM agent with a specific port number on UNIX. Does anyone know how I can do this or am I limited to just associating port numbers with databases.
