Issue appears to be …. trouble parsing or lexing content out from a damn string.
So the knee jerk and IMHO fair reaction is …..
<rant gumpyOldMan="on“>
Oracle should have employed a teenager to do a better job at writing ungraduate
level code.
Oracle should have written comprehensive unit and integration tests for
parsing/lexing a string - after all, it really is not too much to ask that you
test the software you write.
And not for just this issue - it’s just the same old same old and it is
becoming quite tiresome,

Thanks for looking at that Kris! Very much appreciated
I followed the link and found version 21.2.223.0914, which is the version the
jstack output is from (downloaded from Jeff's link earlier). So, unless I
misunderstand you, it still seems to be a problem in the newer version.
Why is it that the parsing goes into an infinite loop only if the password
(or username or service) is wrong? Isn't it finished parsing the TNS string
by the time it sends the password to the database?
Thank you!

grr That says there's a bug in the jdbc driver's parsing of the tns string
sending it into an infinite loop ! I'd grab a newer version and that should
be fixed with the newer driver. Since there's now no-click licenses you can
just curl/wget/download this url directly

Thanks Jeff & Kris,
I've just tried 21.2.2 but am getting the same result as for 19.1.
The jstack output (for 21.2.2) is at 2021-08-23 19:08:22Full thread duimp

I had a quick look at the sqlnet trace output - there was nothing blazingly
obvious but I'm not really sure what to look for. There are plenty on this
list far more knowledgeable so happy to put that up too (will have a look at
comparing a successful connection with a hang).
Thank you!

Just a heads-up in case you’re running into an old bug, 19.1 came out in
April of 2019…latest release is 21.2.2 – came out a few weeks ago. Might be
worth a quick try.

That's curious. We do nothing but sling it over to the db then return when
the db is connected of failed with a message back.
2 options if you have time...
1- when it's hung, run jstack - p <pid> and float it over to me
2- sqlnet tracking to see what the db is doing.

Hello,
I have only just started playing with SQLcl (version 19.1 on Linux) and have
hit an oddity - just want to check if this is expected?
sql charlotte/mypassword@myhost/MYSID <-- connects fine
sql charlotte/wrongpassword@myhost/MYSID <-- hangs
Is it meant to hang if I get my password wrong? It looks like a bug (or at
least a misconfiguration) but since I'm new I want to make sure I'm not
overlooking something obvious.
Verbose mode shows nothing after:
INFO: Attempting to connect using URL= "jdbc:oracle:oci8:@myhost:MYSID"
The hang also happens if I get the username or service wrong (it errors if
the host is wrong). And it's the same if I use nolog and then the connect
command.
Thank you!
Charlotte
