I am using Oracle SQL Developer 4.0.2.15.21 and I want to debug a PROCEDURE. I am unable to do this as I get the following error message...
Executing PL/SQL: ALTER SESSION SET PLSQL_DEBUG=TRUE
Executing PL/SQL: CALL DBMS_DEBUG_JDWP.CONNECT_TCP( '192.168.1.88', '54159' )
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
Process exited.
Can anyone help me ?
In SQLDeveloper go to 'Tools' -> 'Preferences' -> 'Debugger'
Click the option for 'Prompt for debugger host for database debugging'
I have had the same problem. The source of the problem was the local firewall that block the connection back from the database server (windows 7).
To solve it I authorized SqlDevelopper to communicate through Windows Firewall.
Control Pannel\ Security .. \Firewall\ Authorized programs to communicate ...
The path for Windows French version is
Panneau de configuration\Système et sécurité\Pare-feu Windows\Programmes autorisés
In the programs' list search for sqldeveloper (sqldeveloper64w in my configuration) check on the corresponding network (private and or public).
For further details I suggest to read the following article :failure establishing connection to debugger tips

I'm trying to connect to a server from my client using gRPC, but connection always fails only on my pc(macbook pro). My teammate tried with the exact same code, and it works perfectly fine. The following is the error messages from each client and server. We are using protobuf 3, python 3.9. Can anyone give me some hint? Thank You.

I am trying to read the file from Remote SFTP server using Mule Requestor in MuleSoft version 3.8.5. I can see in the logs connection is getting established with Remote SFTP server but while closing the connection its throwing an error as below :
Error occurred while closing file fileName.dat
java.io.IOException: Pipe closed
I am not sure is it due to file length and connection is getting timed out or anything else.
After Mule requester, Byte-Array to String transformer is there. And exception is thrown there is :
Could not close stream
java.io.IOException: Pipe closed

Any suggestion or help is appreciated.
This seems to occur when the sftp connection is terminated by the sftp server or cut by e.g. a firewall. I was able to recreate the issue at will using the tcpkill (8) command to terminate the sftp connection that Mule runtime holds open.
Using a pooling profile with eviction times seems to work.
<sftp:config name="Upload_CSV_SFTP_Config" doc:name="SFTP Config" doc:id="88bf2e97-86d2-40fc-af79-536ec838f2d2" >

Mule 4 SFTP Config
Before that, I had tried various combinations of the basic reconnection options on the SFTP config and also the options on the SFTP operation itself, but none seemed to help. One 'hack' that I used at first was to put an SFTP List operation with a path of . (current directory) immediately before the SFTP Read or Write operation.
A send port configured with WCF-SAP adapter is failing with Unknown error description error logged to Biztalk event log.
In the event of this error we can see that the iDOC is already sent to the SAP system before the error occurred, but due to this error Biztalk thinks that the iDOC has not been sent to SAP and hence retries to send the iDOC after retry interval of 5 minutes which is creating a duplicate of the iDOC in the SAP system as well as in biztalk by archiving 2 files. Not sure of the cause of the error as it is a very generic error.
Can someone please suggest if you had similar situation or cause for this error anyway related to wcf-sap adapter in BT 2013 R2 ? Thank you.
Here is the error:
A message sent to adapter "WCF-SAP" on send port "xx" with URI
"sap://CLIENT=xx;LANG=EN;#a/xx/xx?GWHOST=xx&GWSERV=xx&ListenerGwServ=xx&ListenerGwHost=xx&RfcSdkTrace=False&AbapDebug=False"
is suspended. Error details: Unknown Error Description MessageId:

Verify at the adapter settings that EnableBizTalkCompatibilityMode is set to True. And the checkbox Use Transactions is enabled and Isolation Level selected is Serializable.
Also are you using the NCo ConnectorType to connect to SAP? This is the recommended way.
I am trying to get a connection string right, and using odbcad32.exe to test the connection.
The trouble is, I get Connection Established, regardless of what password I enter.
This seems pretty useless.
My .NET program fails with Data source name not found and no default driver specified even though odbcad32.exe has no problem getting the connection.
Data Source Name : Test_Blah
Description: Test_Blah
Host Name: blh-housing
Port Number: 5060
Database name: ih
User ID: administrator
Driver: Progress OpenEdge 10.2b Driver
Password: (space)
This is my connection string:
<add name="BlhConnection" connectionString="DSN=Test_Blah;UID=Administrator;PWD=' ' ;" />
Any ideas how I can get this working?
32 bit ODBC Drivers and connections based on those are only accessible by 32 bit clients.
You are not mentioning your OS - but when your client application is a 64 bit application the 32 bit ODBC driver won't work. I am not 100% sure - but I doubt that there is a 64 bit ODBC driver for OpenEdge in 10.2B. On OpenEdge 11 that's no problem.
I would start by verifying that you have the correct login credentials. Especially since you state that you get the same result no matter what you use.
The easiest way to verify the credentials is to login to the db server and open a "proenv" session. Using proenv ensures that all of the Progress environment is correctly set. If it is a Windows server "proenv" is in the Progress or OpenEdge program group, if the server is UNIX you can run "$DLC/bin/proenv" from the command line. Once you are running a proenv shell you can then use the "sqlexp" tool that Progress provides to verify your connection string and credentials. For example:
sqlexp -user userName -password passWord -db dbName -S portNum
I'm using ASP.NET 2.0 to connect to a Sybase SQL Anywhere 5 server. And I get this error sporadically. It just happens sometimes. The error message is:
ERROR [HY000] [Sybase][ODBC Driver]General error: attempted two active database requests
Exception Details: System.Data.Odbc.OdbcException: ERROR [HY000] [Sybase][ODBC Driver]
General error: attempted two active database requests
Anyone has any experience with this problem?
The error message means that you attempted to run two queries at the same time using the same database connection.
Are you trying to use the same database connection for all requests? The requests are handled by several threads, so each request needs to have it's own database connection.
Sounds like you're reusing the same connection for multiple commands. Check that you properly dispose of the connections after each command/batch of commands and that all new commands get a new connection.
