问题
I'm trying to run the sql developer in debug mode and i get the following error. I turned off the firewall on the windows machine. (I think my antiviruses firewall is still turned on, i'm not sure if it causing)
Executing PL/SQL: CALL DBMS_DEBUG_JDWP.CONNECT_TCP( 'xx.xx.xxx.xx', '51814' )
ORA-30683: failure establishing connection to debugger
ORA-12535: TNS:operation timed out
ORA-06512: at "SYS.DBMS_DEBUG_JDWP", line 68
ORA-06512: at line 1
What could be causing this issue?
Another Question, i'm new to sql develper+PL/SQL development. I have a lot of dbms_output.put_line(string) statements in the pl/sql code. I need to see what it is printing, does this show up in the sql developer logs/console only if the debugger is turned on?
Edit:
If debugger is not required to print the dbms_output.putline statements then how do i run the already existing methods in a package and make it print in the dbms output console?
回答1:
To see the results of your DBMS_OUTPUT calls, you need to enable DBMS_OUTPUT in the client. In SQL Developer, select View -> Dbms Output. In the Dbms Output pane, click the green plus sign to enable output processing.
(The DBMS_OUTPUT calls in PL/SQL simply put data into a buffer in memory on the server. In order to actually see the output, the client needs to be told to fetch and display the contents of this buffer.)
