ORA-12637 and Oracle 19.5.1 support

[heidenbluth]

Hello,
one of our customers complained about ORA-12637 when connection to an Oracle 19.5.1 EE or SE respectively (Solaris).
I haven't Sun Solaris. and Windows has not yet been released, but I guess it may have to do with DISABLE_OOB (Out Of Band Break) Doc ID 373475.1.

Do you support Oracle 19.5.1 ?

Regards,
Holger

Hello

To reproduce the issue, we need more details. Please give us the following information: does the user employ Direct mode or Oracle client (in the latter case, please specify the exact version of Oracle client); the content of the sqlnet.ora file from the server and, in Oracle client is used, the content of the sqlnet.ora file from the client.

The problem occurs both with SQL*Net and direct TCP/IP connections.
The sqlnet.ora file on the server is unchanged as created by Oracle installer.
On the client there was no sqlnet.ora file.

Following a suggestion from this link
https://github.com/oracle/docker-images/pull/1529
our customer created an empty sqlnet.ora file on the client and added a line

Code: Select all

DISABLE_OOB=ON

Now a SQL*Net connetion could be established.
It looks like it would be a good idea to implement the feature "out of band breaks".
The URL mentioned above has some further links to Oracle Doc IDs.

We'll investigate the issue with Oracle connection in the "Out Of Band Break" mode and notify you as soon as it's resolved.
