ORA-12162 when connecting to database since upgrade to 1.3.0

[glM26]

1. What versions are you using?

python-oracledb 1.3.1
Oracle DB 19c
RHEL 7.9
Python 3.8

2. Is it an error or a hang or a crash?
   error
3. What error(s) or behavior you are seeing?
   We are using python-oracledb in thick-mode to connect to an Oracle database specified in a tnsnames.ora file (i.e. TNS_ADMIN is set to point to the tnsnames.ora file).
   We are also using a sqlnet.ora file that contains a reference to a wallet that contains the DB user and password.

We connect to the database in the following way:

>>> import oracledb;oracledb.init_oracle_client();oracledb.connect(dsn="TEST.WORLD")
<oracledb.Connection to externally identified user>

This is working in python-oracledb up to version 1.2.2.
Since version 1.3.0 (as well as 1.3.1) the same code now results in an error:

>>> import oracledb;oracledb.init_oracle_client();oracledb.connect(dsn="TEST.WORLD")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/PYTHON_LIBS_38/lib64/python3.8/site-packages/oracledb/connection.py", line 1008, in connect
    return conn_class(dsn=dsn, pool=pool, params=params, **kwargs)
  File "/PYTHON_LIBS_38/lib64/python3.8/site-packages/oracledb/connection.py", line 133, in __init__
    impl.connect(params_impl, pool_impl)
  File "src/oracledb/impl/thick/connection.pyx", line 387, in oracledb.thick_impl.ThickConnImpl.connect
  File "src/oracledb/impl/thick/utils.pyx", line 413, in oracledb.thick_impl._raise_from_odpi
  File "src/oracledb/impl/thick/utils.pyx", line 403, in oracledb.thick_impl._raise_from_info
oracledb.exceptions.DatabaseError: ORA-12162: TNS:net service name is incorrectly specified

The tnsnames.ora file:

TEST.WORLD =
  (DESCRIPTION =
    (CONNECT_TIMEOUT=10)(RETRY_COUNT=3)
    (ADDRESS_LIST =
      (ADDRESS=(PROTOCOL=TCP)(HOST= primary_url)(PORT=1721))
      (ADDRESS=(PROTOCOL=TCP)(HOST= secondary_url)(PORT=1721))
    )
    (CONNECT_DATA=(SERVICE_NAME=TEST_PRIM.WORLD)(SERVER=DEDICATED))
 )

I can still connect to the database in 1.3.1 with all parameters in the connect-statement:

>>> import oracledb;oracledb.init_oracle_client();oracledb.connect(host="primary_url", port=1721, service_name="TEST.WORLD", user="TEST", password="")

<oracledb.Connection to TEST@(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=primary_url)(PORT=1721))(CONNECT_DATA=(SERVICE_NAME=TEST.WORLD)))>

Have there been any changes in release 1.3.0 that I overlooked or is there a bug in release 1.3.0?

[anthony-tuininga]

I'm not immediately aware of any changes that might be relevant. Looking at your sample tnsnames.ora I see the service_name is TEST_PRIM.WORLD, not TEST.WORLD as in your connection with all of the parameters. Is that just an oversight? I'll look into this and get back to you.

We have been using the TEST_PRIM.WORLD in tnsnames.ora for quite some time now, while still connecting to TEST.WORLD.
I do not know why we use this, as we got the tnsnames.ora in this form from our DBA-team a couple of years ago.

But I just tried to change TEST_PRIM.WORLD to TEST.WORLD and it does not change the behavior, i.e. ORA-12162.

@glM26 would you be able to create a sqlnet.ora file (on the machine where your tnsnames.ora file is) and add some tracing like:

trace_level_client=USER
adr_base=/tmp/mylogs
diag_adr_enabled=ON

Then execute mkdir /tmp/mylogs and run your app. Somewhere down the log dir will be a sqlnet.ora file: /tmp/mylogs/oradiag_*/diag/clients/user_*/host_*trace/sqlnet.log

Can you check that the connect descriptor is what you are expecting? There might be a few extra, expected attributes including CID and CONNECTION_ID.

[glM26]

@cjbj
I added the trace-options to sqlnet.ora, it now looks like this:

WALLET_LOCATION =
    (SOURCE =
        (METHOD = FILE)
        (METHOD_DATA =
            (DIRECTORY = /opt/shared/shsdb/operation/etc/oracle_wallet)
        )
    )
SQLNET.WALLET_OVERRIDE = TRUE
TRACE_LEVEL_CLIENT=USER
ADR_BASE=/tmp/mylogs
DIAG_ADR_ENABLED=ON

With this I get the following trace-log (only first 64 lines) with oracledb 1.2.2:

When running with oracledb 1.3.0 it looks similar in the beginning, but then it just stops at nigconcbs:Can't Get Oracle SID Name:

@glM26, the level of trace provided is insufficient to figure out the issue. Can you change the line in sqlnet.ora to say trace_level_client=support and rerun? Thanks!

[glM26]

@anthony-tuininga I changed trace_level_client to support and reran the program:

[anthony-tuininga]

Thanks for the traces. That was helpful.

I have pushed a patch that should correct this issue and a relevant test case. If you are able to build from source you can verify that it corrects your issue as well.

Someone else noted that if you do this it will also work (without the patch):

conn = oracledb.connect(dsn="@tns_alias")

[glM26]

@anthony-tuininga thank you for help, I can confirm that both suggestions (building the newest version from source as well as adding @ in front of the dsn) solved my issue.
Do you know when a new version of oracledb containing the fix will be released?

[anthony-tuininga]

Thanks, @glM26. We will discuss internally but generally we like to make a release that contains bug fixes within a few weeks at most. I will post here when a release is made that contains this patch.

[anthony-tuininga]

This has been fixed in python-oracledb 1.3.2 which was just released.
