Where does UTL_MAIL queue emails?

User_XOTKGJun 1 2022

So I'm working on a Dev DB and I need to send emails out with UTL_MAIL. Check the parameters, and I need to set smtp_out_server parameter in the spfile, as it is currently NULL. I set it to my SMTP server, and WHAM: thousands of emails come pouring out to my mail server. So I rush to NULL the parameter out again. But clearly some other developers have been testing UTL_MAIL execution without actually sending anything out.
So my question is, where does Oracle queue mails that are created by UTL_MAIL but cannot be sent because smtp_out_server is incorrectly configured? Because I need to clear that location out before I re-enable the parameter.
Thanks!

This question has been asked before, and it seems like sqlcl still has an issue with running in the background as opposed to the expected behavior when using sqlplus ( as discussed in How can I run sql script in background? )

However a more recent discussion proposes a workaround which uses javascript to run the sql in the background of your current sqlcl session: run a script in the background ??

Hope this helps

any fixable solution for this ?

No.

Workarounds, yes.

. screen

. tmux

. vncserver / vncclient

...etc.

The issue with sqlcl, I believe, is the way it has been written whereby is incompatible with being put into the background "as is" with nohup, &, bg, so needs a helper process, offered by something like the above.

Hi all,

The problem is that sqlcl uses the bash commands to detect the terminal width and  height. Since this only works on Linux, this problem won't exist on Windows.

Inside SQLcl there is a condition that checks whether the program is running on Windows and if so, it does not check the terminal size. It uses system property "os.name" for that so you can do a little hack and provide the value of that property on java command line -Dos.name=win. SQLcl is started from sql command in bin directory so just adding the property as below should work.

$JAVA  $CUSTOM_JDBC $CYGWIN "${APP_VM_OPTS[@]}" -client $DEBUG -Dos.name=win -cp "$CPLIST" oracle.dbtools.raptor.scriptrunner.cmdline.SqlCli "$@"

Regards,

Tomas

I apologise, the fix I was proposing above won't work as there are several other dependencies on "os.name" throughout the call, also os.name should be "Windows 8.1" or alike, "win" is invalid.

My problem was that when running this in background from python the sqlcl code around terminal was causing the issues. I fixed it by allocating a dedicated TTY for the process.
