When I log onto the docker machine through docker exec -i -t <container_id> bash I can successfully run sqlplus system/oracle@localhost:1521/xe

When I'm on my local machine and try and run that, it cannot connect: sqlplus system/oracle@//192.168.99.100:1521/xe.oracle.docker or sqlplus system/oracle@//192.168.99.100:1521/xe or sqlplus system/oracle@192.168.99.100:1521/xe all give me the same ORA-12162: TNS:net service name is incorrectly specified error. 192.168.99.100 is my docker-machine ip. Same happens if I try localhost

I can successfully connect to the web portal at http://192.168.99.100:8080/em and login

Any help appreciated

I had to modify $ORACLE_HOME/network/admin/*.ora files to listen to 0.0.0.0 instead of the hostname. Does that make sense ?

KidA001 commented 7 years ago

@anilsamuel this is my tnsnames.ora

ORCL =
 (DESCRIPTION =
   (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.99.100)(PORT = 1521))
   (CONNECT_DATA =
     (SERVER = DEDICATED)
     (SERVICE_NAME = XE)
   )
 )

Generally localhost/0.0.0.0 doesn't work for me, are you suggesting to change 192.168.99.100 to 0.0.0.0 ?

anilsamuel commented 7 years ago

yes, change 192.168.99.100 to 0.0.0.0.

anilsamuel commented 7 years ago

I would commit my changes once I got it working; else you would loose on docker container shutdown

Interesting...I started getting a different error (ORA-21561: OID generation failed) when I used: sqlplus system/oracle@//192.168.99.100:1521/xe ... note xe at the end instead of xe.oracle.docker

I looked up the ORA-21561: OID generation failed error and found this post on stackoverflow. I updated my /etc/hosts file entry for localhost from 127.0.0.1 localhost to 127.0.0.1 localhost MacBook-Pro-2.local

Now I'm able to connect with sqlplus system/oracle@//192.168.99.100:1521/xe @anilsamuel

@KidA001 Where is the tnsnames.ora you put? I can not find a folder like network/admin. Which is the $ORACLE_HOME? mounted on /u01/app/oracle?
