Hello All,

Need help

We are having installed oracle 12c.
The client is using Toad (Version 9) and Forms and Repports (version 6i), to connect to our 12c DB.

We made entry of SQLNET.ALLOWED_LOGON_VERSION=(8') in the server's SQL NET and Clients SQL Net files, also restarted the Listner service.

But we are getting the error of "ora-28040 no matching authentication protocol". By connecting through Forms.

But no problem occured while connecting through TOAD.


Thanks and regards.
Muktha

Smart people on OTN say that the reason might be Forms 6i client version which is trying to connect to your 12c database. As Forms 6i uses 8.x client (8.0.6?), regarding Client / Server / Interoperability Support Matrix For Different Oracle Versions (Doc ID 207303.1) (on My Oracle Support), this was never supported so ... it seems that you are out of luck.

Hopefully, someone else will know the workaround (I don't, sorry).

Hi All,

I have found the soulution,
that the parameter SQLNET.ALLOWED_LOGON_VERSION is depricated in 12c with SQLNET.ALLOWED_LOGON_VERSION_server and SQLNET.ALLOWED_LOGON_VERSION_client.

Thanks

OK, so - what exactly did you do? Future readers might benefit from it.

Hi Littlefoot,

Add those parameters in server and client's machine with the value of 8.

eg:-
SQLNET.ALLOWED_LOGON_VERSION_server=8

Muktha, I was under the impression that it is 100% impossible to connect an 8.x client to a 12.x database. I can't test this right now, please can you do a demonstration for me? You don't have to, but it might be helpful for other people.
Can you launch SQL*Plus from your Forms and Reports home and logon to the database? Use the character version (sqlplus.exe, not sqlplusw.exe) and copy/paste it, to show both the client version and the DB version?

The correct parameter is SQLNET.ALLOWED_LOGON_VERSION_CLIENT (which does not mean it will succeed).

Note that "but that not connect with 12c " is not an Oracle error message and help in no way to know why it "not connect with 12c".

Forms 6 can not inter-operate against V12 database; since SQL*Net only inter-operates across two major version.
Forms 6 is either V7 or V8 Oracle DB vintage.
