Oracle DB 23.4.0 FREE setup binds to docker host name #2823

Closed tomasr closed 1 week ago

tomasr commented 1 week ago

Seems like the 23.4.0 setup files will produce a non-working tnsnames.ora file that is bound to the docker hostname instead of 0.0.0.0:

# tnsnames.ora Network Configuration File: /opt/oracle/product/23ai/dbhomeFree/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

FREE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = f545cf6d23da)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = FREE)
    )
  )

LISTENER_FREE =
  (ADDRESS = (PROTOCOL = TCP)(HOST = f545cf6d23da)(PORT = 1521))

FREEPDB1 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = FREEPDB1)
    )
  )

This causes a failure during startup because the TNS listener won't start if the hostname has changed:

Oracle Database instance FREE started.

Failed to start Oracle Net Listener using /opt/oracle/product/23ai/dbhomeFree/bin/tnslsnr and Oracle Database using /opt/oracle/product/23ai/dbhomeFree/bin/sqlplus.
The Oracle base remains unchanged with value /opt/oracle

Looking at the setup scripts, the way tnsnames.ora was definitely changed between 23.3.0 and 23.4.0.

Looking at this a bit closer, I think the issue might be less tnsnames.ora and more listener.ora, which is still bound to the hostname.

Hi @tomasr

I build and ran 23.4 free container on my machine. For me the files created are correct. Output below:

bash-4.4$ podman run -td --name free23.4 oracle/database:23.4.0-free

bash-4.4$ podman logs -f free23.4
