I just installed oracle 12c standard edition to test compatibility for database that will be migrated to oracle 12c from oracle 10g.
I installed it succesfully, it gave me the url of my database ( https://localhost:5500/em ) and I chose an SID (TEST). Then I create a new user and import the .dmp file of the database I had on Oracle 10g. So far so good.
Then I connect to the user and check around, tables are imported, insertions also, good.
Then I try to connect from sql developer... No way to do it.
Question I have:
I have tried every single combination of sid and port but nothing works. It was so easy to configure it with oracle 10/11g so of course I know I am misunderstanding something. I have looked for info to see the ports and I saw that there is a file called portlist.ini but it is empty.
Any help or guidance to go throw the issue would help me a lot, I have been like 6 hours researching and trying to solve it.
Thanks!
For the listener port you should check your listener.ora file. You also can get these information from the output of:
lsnrctl stat
I think you've installed your 12c as a container database. This makes connecting a bit different. Try connecting by service_name not by tns. This is as in previous versions.
