Hi.
I’ve just installed SQL Navigator 6.0.0.1055
Whenever I try to expand an entry in the DB Explorer like “Tables”, “Views”, … I get the “Synonyms” entry and then an “ORA-12571: TNS: packet writer failure” entry (this means that the error message does not appear in a separate window).
I’ll attach an hardcopy of the DB Explorer.
Everything works fine with SQL Navigator 5
Any hints on this?
Thanks,
Marco.
Hi Marco,
Could you check in the relevant sqlnet.ora file whether you had this parameter
SQLNET.AUTHENTICATION_SERVICES= (NTS) in it?
If so, then replace the value “NTS” with “NONE”, like this:
SQLNET.AUTHENTICATION_SERVICES= (NONE),
save the file, open SQL Nav 6.0 and try expand DB Explorer again.
Rgds,
Andrew
Hi Andrew,
thanks for your answer.
Unfortunately I’m still getting the error.
Maybe this helps someone to solve my problem:
SQLNET.LOG in the SQL Nav. 6 directory says:

I am going to throw something out, this may be way in left field, but did you check the Oracle Home client on the login screen. We had someone here who had a problem and it turned out they had the wrong default (I don’t believe they were having the same problem though).
Thanks Lozier for your answer, but selecting an explicit Oracle_Home did not help.
Hi Marco, It appears that you are connecting to unsupported Oracle version 8.0.6. You need to check which version of Oracle client is installed on your PC and whether it is compatible with 8.0.6 database. Please also, look at “Release Notes for SQL Navigator 6.0” for information System Requirements.
BTW Are you using SQL Nav to work with Oracle DevSuite? Do you have only one Oracle_Home? Not long ago, we had in this Forum a discussion of compatibility between Oracle Forms and SQL Nav connection manager. If you find this thread you may find something useful.
In long term, I believe, upgrading your Oracle will help SQL Nav 6.0 to work properly. Best wishes, Andrew
