ORA-30683: failure establishing connection to debugger

Asked by: gram77

I am trying to debug a simple pl/sql code using SqlDeveloper 1.5.1

Though I am able to get connected to the database, I get an error while establishing connection to debugger.

The error is thrown by:
Executing PL/SQL: CALL DBMS_DEBUG_JDWP.CONNECT_TCP( '11.111.11.111', '1528' ) --provide my pc's IP
Executing PL/SQL: CALL DBMS_DEBUG_JDWP.CONNECT_TCP( '22.222.22.222', '1528' ) --provide remote db's IP

This procedure takes 2 parameters:
1. IP Address: The error is the same if i provide my pc's IP address or the remoteDB's IP address
2. Port#: Port# 1528 is open, as it is the same port# mentioned in tnsnames file.
      I have also got this confirmed that the port# 1528 is open from the networks team, and there is no firewall blocking the port# 1528.
      and using traceart i am able to see the packets comming from the remote db 11.111.11.111 to my pc 22.222.22.222

I have also enabled Tools->Properties->Prompt for database host for debugging check box.

Supplying IP address of my pc: 11.111.11.111
Connecting to the database PBSD.
Executing PL/SQL: ALTER SESSION SET PLSQL_DEBUG=TRUE
Executing PL/SQL: CALL DBMS_DEBUG_JDWP.CONNECT_TCP( '11.111.11.111', '1528' )
ORA-30683: failure establishing connection to debugger
ORA-12560: TNS:protocol adapter error
ORA-06512: at "SYS.DBMS_DEBUG_JDWP", line 68
ORA-06512: at line 1
Process exited.
Disconnecting from the database Remotedb.


Supplying IP address of my pc: 22.222.22.222
Connecting to the database PBSD.
Executing PL/SQL: ALTER SESSION SET PLSQL_DEBUG=TRUE
Executing PL/SQL: CALL DBMS_DEBUG_JDWP.CONNECT_TCP( '11.111.11.111', '1528' )
ORA-30683: failure establishing connection to debugger
ORA-12560: TNS:protocol adapter error
ORA-06512: at "SYS.DBMS_DEBUG_JDWP", line 68
ORA-06512: at line 1
Process exited.
Disconnecting from the database Remotedb.

When my IP supplied is correct and the port# 1528 is open and exists, then why do i get this error?

gram77 before anything please execute the same code in sqlplus ;
and show the results;
sqldeveloper is really...you know

 

by: it-rexPosted on 2009-08-26 at 09:04:57ID: 25189232

1-Check if you have a firewall between the SQLDeveloper and the Database Server.  could be a hardware firewall on the network causing the problem.

2.  Also check the PC settings and see if it is using a local software firewall.  Turn off the local software firewall or open the specific ports.

try this

from menu-->'Tools --> preferences --> debugger'
check 'Prompt for debugger host for database debugging'
With this option SQL Developer ask the IP address where it is installed;this should resolve your problem;if you are using TNS connection ;

or you can just use basic connections

Is there any way i can show the network guys, that here a firewall is blocking access?

 

by: it-rexPosted on 2009-08-27 at 06:49:15ID: 25198083

try this for now before the firewall thing;this will solve your problem as per Oracle



from menu-->'Tools --> preferences --> debugger'
check 'Prompt for debugger host for database debugging'
With this option SQL Developer ask the IP address where it is installed;this should resolve your problem;if you are using TNS connection ;

it-rex:
"where it is installed" i think you mean where the database is installed.

I am already using this feature of sqldeveloper. I am entering the ip address of the database server.

I think the error is with the port.

Want to know how to show the support guys that here is the firewall block i am talking about.

telnet does not work either. telnet  147.107.XX.XXX

 

by: it-rexPosted on 2009-08-28 at 06:44:46ID: 25207559

I am providing my PCs ip, and i continue to have this connectivity issue connecting SqlDevloper debugger to my PC

 

by: gram77Posted on 2009-08-31 at 09:05:32ID: 25223934

My tnsnames is using the port 1528.

RAC1_abc =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = abc.com)
     (PORT = 1528))
     (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = abc)
      (INSTANCE_NAME = xyz21)
    )
 )

My pc is connecting to the db on port 1528 as seen on the above entry.

Can i connect to the debugger of sqldevleloper using the same port ie. 1528.

I have tried this but still i could not connect.

Someone told me i cannot connect the debugger as well as the db on the same port, why?

 

by: it-rexPosted on 2009-09-01 at 13:24:25ID: 25235611

try this

Connect in SQL*Plus as a DBA and grant the privileges DEBUG CONNECT SESSION and DEBUG ANY PROCEDURE to your user:

GRANT DEBUG CONNECT SESSION to <user> ;
GRANT DEBUG ANY PROCEDURE to <user> ;

 

by: it-rexPosted on 2009-09-01 at 13:36:31ID: 25235737

would you plesae try to use basic connection instead of tns;and let me know

 

by: gram77Posted on 2009-09-01 at 23:06:40ID: 25238296

it-rex:
I am able to connect to sqldeveloper debugger.

The debugger requires two parameters:

CALL DBMS_DEBUG_JDWP.CONNECT_TCP( ip, port# )

The problem was that my IP is modified intermittently as it passes through hJXX to hBXX, due to which there was a communication barrier.

I was entering a static ip got through ipconfig command

I resolved it by providing the host name given by the network team, and it always resolves to the new ip through dnsnames server
