Re: [External] : Re: SQLcl Connection

 Hi Kris,
Yes, adding the port number avoids the hang (with or without // before the hostname).   The database is using the default (1521) but I can specify this to avoid the problem. Many thanks for the suggestion.
Charlotte

Structurally these are the same so it doesn't make sense one would work and one not which is confusing

Does this work?  sql charlotte/wrongpassword_at_//myhost:1521/MYSID ?

 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!Charlotte

 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   >  https://download.oracle.com/otn_software/java/sqldeveloper/sqlcl-latest.zip

 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 Java HotSpot(TM) 64-Bit Server VM (25.261- - Pastebin.com 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!Charlotte

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.

You SHOULD see something like this –  

HR_at_orcl> disconnect

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_at_myhost/MYSID  <-- connects fine  

sql charlotte/wrongpassword_at_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:_at_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!
