Docker GoldenGate 26ai - failed TNS_ADMIN

Matthieu COUSSIFeb 5 2026

Hi,

I've deployed a Golden Gate console from docker image :

https://container-registry.oracle.com/ords/ocr/ba/goldengate/goldengate-oracle

The console works fine but when i tried to configure in Administration Console a Database Connection and test it, it failed :

Login failed. [OGG-00664] Error 12162 on OCI call [ORA] - ORA-12162: TNS:net service name is incorrectly specified Help: https://docs.oracle.com/error-help/db/ora-12162/ .

The TNS_ADMIN is configured in container [/u02/Deployment/etc] in the Deployement Group.

So i created the tnsnames.ora with a TNS Alias (i tested thsi file externaly and it worked)

[xxx@xxx-xxx goldengate] $ docker exec -it xxxxxxxxxx bash -lc 'cat /u02/Deployment/etc/tnsnames.ora'

xxx=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=xxxxxxx)(PORT=xxx))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=xxx)))

Thanks for your help,

Matt
