Oracle Port Numbers tips  

Expert Oracle Database Tips by Donald BurlesonNovember 24, 2015

Question:  How do you change Oracle port number in Oracle Enterprise Manager (OEM)?

Answer:  There are a number of ports set during the Oracle setup process, and there are any number of reasons why you might want to change those ports following your Oracle installation.

Additional information on Oracle's use of ports for its processes is available through the list of articles HERE.

The monitoring of metrics and exceptions is a critical part of the performance tuning process.  OEM alerting is an integral part of this process.  Information on OEM alerting in general and setting email parameters through the OEM is HERE.

A reader asks:

"I want to configure the Email Alert Notification in OEM.

 In OEM --> Setup --> Notifications Methods --> I am able to see a provision to enter SMTP Address, but there is no port number. Due to some security policies, my company has opened only Port Number : 9925 for SMTP and blocked Port number : 25.

When I click on "TEST MAIL SERVERS" button, it gives me a error that :

Test failed with message : Could not connect to SMTP Host , Port No. 25

Now I want to change this port number 25 to 9925."

How can this be accomplished?

Rampant author Kamran Agayev responds:

Read the text that's under "Outgoing Mail (SMTP) Server" textbox

"Use the format SERVER:PORT (Example: SMTP1:587). "
