Failure establishing connection to debugger

Hi all,
I'm using SQL developer 3.1.07 and I'm unable to use the debugger functionality. I've searched and found a number of other threads that relate to either VPN's or users putting the server address in the debugger host but I'm still unable to resolve the issue.
The difference here may be that I have virtualbox set up on my pc and have all the associated VM IP addresses set up.
Virtualbox is not running when I attempt this.
the message I'm getting is (IP address hashed out):
Connecting to the database whitehat.
Executing PL/SQL: ALTER SESSION SET PLSQL_DEBUG=TRUE
Executing PL/SQL: CALL DBMS_DEBUG_JDWP.CONNECT_TCP( '###.29.34.96', '65078' )
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 1The above address is the one chosen by SQL developer initially and is also the one shown in my sys_context('userenv','ip_address').
The database server itself is not on my PC, but is readily accessible on the network.
I'm at a bit of a loss as to how to proceed. any suggestions?

It might be a firewall issue; especially if you have been working with VM on that machine.
While you wait for one of the sql dev people to respond you may want to review this doc about 'Running and Debugging PL/SQL and Java Stored Procedures'.
This is from the Fusion Middleware doc for JDeveloper but sql developer is based on JDeveloper
http://docs.oracle.com/cd/E16162_01/user.1112/e17455/dev_stored_proc.htm

29.3.2 How to Specify the Database Debugger Port
When the database debugger is running, for example to debug PL/SQL through a database connection, the ports used are randomly assigned. This can cause problems with firewalls, and to avoid them you can edit the ide.properties file to ensure that a specific port is used.
To specify the port:
If necessary, close JDeveloper.
In a text editor, open jdev_install/jdeveloper/jdev/system/oracle.jdeveloper.release_number/ide.properties.
Type the following:
DatabaseDebuggerPortOverride=port_number
where port_number is the port number you want the debugger to use.
Save ide.properties. When you restart JDeveloper, the port you specified will be used.

The entire section at the link provides more information about establishing a debugger connection if you haven't done that before on any machine.

The database needs to be able to contact your PC, and I think your IP on the VPN is 172.20.34.16 rather than 130.174.12.111, correct?
If so, check Preferences - Debugger - Prompt for Debugger Host, initiate another debug session, and when prompted, give that IP instead. Once you had a successful debug session, I'm pretty sure you can uncheck the preference again.
If still no go, some firewall (PC or network) might be blocking the database from reaching your PC.
Hope that helps,

Debugger on Windows Vista - ORA-30683: Failure establishing connection to d

We can't get the debugger to work on our Vista machines... On our XP machines we don't have this problem, so I suspect it's a "Vista" issue.
The vista machine is a desktop running sql developer, connection to another machines (server's) database. XP machines connect and debug on that same database fine.
We get this error when debugging:
Executing PL/SQL: CALL DBMS_DEBUG_JDWP.CONNECT_TCP('0.0.0.0', '4000')
ORA-30683: Failure establishing connection to debugger
ORA-12541: TNS: no listener
ORA-06512: at "SYS"."DBMS_DEBUG_JDWP", line 68
we've tried:
1) controlling the port on the SQL Developer preferences to be 4000, then making an exception on the firewall (on the vista machien) for that port
2) making an exception for sql developerj.exe files
3) Running it as an administrator
no luck.
I do notice that on teh first line, it puts: CONNECT_TCP('0.0.0.0', '4000')
The zero's... on an xp machine, the IP: 127.0.0.0 would be there instead. Not sure if that's related to the problem.
Please help, we can't debug on our Vista machines until this is resolved.

Definitely. The database needs to be able to contact your PC, so '0.0.0.0' won't work.
Check Preferences - Debugger - Prompt for Debugger Host, initiate another debug session, and when prompted, give your IP instead. Once you had a successful debug session, I'm pretty sure you can uncheck the preference again.
Have fun,
K.

Process terminated without establishing connection to debugger

I'm using FB 4.5.1 on Windows and trying to use StageVideo for a mobile app. The video file plays, I can hear audio but no video. In multiple posts I've seen that you need to add -swf-version=13 or -swf-version=14 to the compiler options. I have AIR 3.1 installed on this box so I used 14 (same result with 13) and when I try to run or debug I get the launch error, Process terminated without establishing connection to debugger.
I can use -swf-version=11 and it runs, but the video doesn't work. I've downloaded Flash debugger 11.1 and get the same results as using 10.2. So is my problem because FB doesn't recognize the latest version of AIR or something else?... basically, how do I fix this??

I just had a D'oh moment... Two things: (1) Needed to change the application namespace in application-app.xml to 3.1 and (2 which is the D'oh part), actually install the 3.1 SDK.

Unable to connect to debugger

Developer cannot connect to debugger. when I attempt to execute a procedure in a pcakage to debug it I get:
Connecting to the database DBConnection1.

I can connect with the database via SQL*Plus. SQL Developer is on my machine, is there a listener for the debugger? Any help would be appreciated.

You need to enable 'Prompt for Debugger Host for Database Debugging' under Tools -> Preferences -> Debugger.
Otherwise it is assuming that the database is local to your pc and the remote database can't connect to yours since the ip address defaults to 127.0.0.1. (who knows why they did it this way.. but many other had this problem)

How do I connect the debugger for remotely debugging PL/SQL?

Hi everyone,
Remotely debugging PL/SQL from JDeveloper and SQL Developer is something I have tried unsuccessfully to do.
The steps I took were to right-click my connection, select Remote Debug... and specify "4000" for the Port and "n.n.n.n" for the Local address which seems to correctly start the listener. (I used ipconfig to double-check the address.) Then, I run the anonymous block you see below.
begin
dbms_debug_jdwp.connect_tcp( 'n.n.n.n', 4000 );
end;
But, I always get the following error:
Error starting at line 18 in command:
begin
dbms_debug_jdwp.connect_tcp( 'n.n.n.n', 4000 );
end;
Error report:
ORA-30683: failure establishing connection to debugger

ORA-06512: at "SYS.DBMS_DEBUG_JDWP", line 68
ORA-06512: at line 2
30683. 00000 - "failure establishing connection to debugger"
*Cause:    An error was indicated when trying to establish a connection
           to a debugger. Usually a TNS error will display along with
           this message to further explain the problem, although this
           TNS error will likely be hidden if you choose to trap the error.
*Action:   Correct the indicated parameter value and try again.
Additionally, my firewall in Windows 7 is disabled, and I work remotely from home via VPN.
The instructions are thatI followed: Sue's Blog... again...: Remote Debugging with SQL Developer.
Any help would be greatly appreciated. Thanks!

The bcp program executes successfully on a local instance of SQL Server.

The error has nothing to do with BCP as such, but it is a connection problem. That is, for some reason you cannot connect to your instance from the VM. I would exect that you face a similar problem if you tried SSMS.
It could be a firewall issue, but prelogin suggests that you reach the instance. But possibly you don't come far enough for the login failure to be recorded. Possibly the instance is not configured to audit login failures.
The message you would see would be similar to
2010-08-18 14:11:30.91 Logon Error: 17809, Severity: 20, State: 3
Possibly followed by a a line that details the message. The error number may be different.

Essbase Error(1021001) Failed to Establish Connection With SQL Database...?

Hi there!
I am very new in Essbase and I am receiving the error message quoted below while trying to load data in a Cube. Weird thing is that we have checked all connections already and they are working correctly, however this process is still failing.
If someone can give us an idea to troubleshoot it, that would be really appreciated.
Thanks very much in advance for any help and regards!

So, we checked the database and noticed the schema and their views were damaged and -due to this- they lost all their properties (like data types, for example). So, we had to recompile all of them in order to avoid any loss of data. This was done in TOAD, as per the following info: https://support.quest.com/SolutionDetail.aspx?id=SOL66821
Finally, once all the views on this schema were rebuilt and fixed, we were able to deploy the Cube again.
Hope this help in the future. Cheers!!

Essbase Studio - Failed to Establish Connection With SQL Database Server

Hi all,
I am new to Hyperion and am having trouble deploying what seems a simple cube in Essbase Studio.
My environment is Windows 2003, EPM 11.1.1.2, SQL Server 2000.
I have the following two issues which may be related.
1. The EPM System Diagnostic tool says that Hyperion Foundation cannot connect to the SQL database.
Error:
Failed: Connection to database
Error: java.net.UnknownHostException: <server name: <server name>
Recommended Action:
Every other EPM application is able to connect to the database. I have tried re-configuring Foundation Services and checking the config files and nothing looks wrong. I would appreciate advice on how to fix this.
2 In Essbase Studio, I was able to connect to the database where the source data is, build the minischema and create dimensions and measures. But when I run the cube deployment wizard I get the error:
Message: Failed to deploy Essbase cube
Caused By: Failed to build Essbase cube dimension: (Time)
Caused By: Cannot incremental build. Essbase Error(1021001): Failed to Establish Connection With SQL Database Server. See log for more information
…ODBC Layer Error: [08001] ==> [[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]SQL Server does not exist or access denied.]
I have checked the DSN as well as the connections set up within Studio, and they are all able to connect to the database. I am using the admin user for the Essbase server and have created a different user for the databases where the data resides and the shared services database. I tried using the same user all the way through and this didn’t help.
Can you please advise what else I can check or change to resolve this issue.
Also, can you work in EAS with cubes that are created in Studio? I tried looking at it and I got an error that the rule file couldn’t be accessed because it was created in Studio.
After the above failures, I tried creating a cube in EIS, with mixed success. I have been able to load the members and data without errors. But when I try to view the data in the cube, I am seeing field names for the measures instead of the data itself.
...Definitely more questions than answers at this stage of my learning.
Regards
Michelle

Michelle,
I don't know if you found an answer to you question after so many months but I was hoping I could be helpful.
The issue you are experience happens often when the dimension that you are getting an error on, in this case TIME, is built from a snowflake lineage and there is a bad foreign key reference. This dimension is most like high-up in your outline build process for Essbase Studio and this prevents the build from happening usually early on.
Check your logs also. They are in Hyperion > Products > logs > essbase > essbasestudio.
You can also make your logs more verbose by setting a configuration variable in the essbase studio server.properties file but that should only be used for debugging as it really saps performance.
And, yes, you can of course edit an Essbase Studio deployed cube in EAS. However, any changes you make to the cube in EAS are subject to being wiped-out upon the next Essbase Studio deployment of that Applicaion/Database combo.
If you want to provide more detail, screenshots, etc. I would be glad to help where I can.
Cheers,
Christian

Hi Jack,
I have test the code,both
Asynchronous Client Socket Example and
Asynchronous Server Socket Example works fine on my side.

>>An established connection was aborted by the software in your host machine
From the error message,
Firstly please try to check if there is a firewall between the sender and receiver, make sure that it does not closing the connection because of idle timeout, or just turn off the firewall for testing.
Also someone try to reset to solve the issue.
<Copied>
The issue here was the timeout on the central distributor. That was causing the connection to reset when the receiver did not
pick up the message within the time limit. Alter the reset, when this program tried to receive on the socket it would fail with "An established connection was aborted by the software in your host machine" and this generated the failure audits.

In addtion, there is a thread talking about the similar thread, please have a look.
C# An established connection was aborted by the software in your host machine
Best of luck!

Unable to open any websites from the search engines. the ones I have tried are google, yahoo and ask. They opened until recently. The popup says" Firefox can't establish connection to the server." Ask worked last night but is not working now.

When I try to open a web site from one of the search engines a pop up shows stating that Firefox can't establish connection to the server. I can't open any websites through any of the search engines.

Problem in establishing connection with mysql 5.0

Hi,
I am using JCAPS 5.1. I tried to insert data to mysql database table.
But i got following error
java.sql.SQLException: Error in allocating a connection. Cause:
Physical Connection doesn't exist.
My intention is to read file in which data are comma seperated and to
populate those values to a mysql 5.0 database table.
Sample DATA in file [test.txt]
111,gg,23,MFG
112,hh,24,MFG
113,ii,25,RETAIL
114,jj,26,IT
Database table: employee
eno,ename,eage,edept
While creating JDBC OTD there is no problem in establishing connection with database. But after deploying i got above error.
I have used Mysql 5.0 Connector/J JDBC driver. Added JDBC driver jar files to following directories as required.
1) C:\JavaCAPS51\logicalhost\is\lib
2)C:\JavaCAPS51\logicalhost\is\domains\test\lib
Steps i have followed as per JDBC-ODBC -eway user guide doc.
1) Created USerDefined OTD and added necessary fields
2) Created JDBC OTD.
3) Created JAVA collaboration and do business process for inserting
4) Mapped all components by creating in Connectivity MAp
5) created necessary external systems in envrionment explorer.[JDBC External System and File External System]
6)Created Deployment profile
5) Deployed it.
After deploying it gives error as
java.sql.SQLException: Error in allocating a connection. Cause: Physical Connection doesn't exist
Please let me know the solution for problem.

In the environment definition,
-> External Application JDBC
-> Properties
-> Outbound JDBC Connection
You have the database URL in the "DriverProperties" field
Valid URL would be : jdbc:mysql://localhost:3306/caps
!! The doc says that this field is optional !! Seems to be an error in the doc:
Hope this helps

I used to be able to email photos from my Lightroom software 5.7 for MAC quite successfully. I needed to change my password several days ago in my gmail account. Now when I try to email photos I receive a message saying "Failed to establish connection with the outgoing email server. Please make sure you have entered the email account and password correctly."
I have been trying to get help from Adobe for 3 days. I have sent a message through "Get Support", 2 days ago, but no one has contacted me. I have tried by phone, but no one will help me. When I purchased Lightroom in May, 2014, I was able to receive phone help. I am now told that I don't qualify because I am not a Creative Cloud customer. I have been assigned a case number 186291729.
PLEASE HELP ME FIX THIS PROBLEM

I, too, have this problem. I see no one is responding with a solution? Hello? Can someone please advise?
Oh, and, yes, I have manually verified repeatedly that the information I gave to Lightroom is correct, and I still get the same error message when I try to validate.
