I work with SQL Developer and I want to debug a package procedure.
I run the debug some times and these are the different values of host and port
CALL DBMS_DEBUG_JDWP.CONNECT_TCP( '10.50.10.117', '62378' )
CALL DBMS_DEBUG_JDWP.CONNECT_TCP( '10.50.10.117', '62388' )
These are the sql developer preferences
I added the line
AddVMOption -DDatabaseDebuggerDisableJDWP=true
in the file sqldeveloper.conf
I have a question: is it mandatory to open the port 4000?
The error is
Connecting to the database Copernico Produccion 1.
Executing PL/SQL: ALTER SESSION SET PLSQL_DEBUG=TRUE
Executing PL/SQL: CALL DBMS_DEBUG_JDWP.CONNECT_TCP( '10.50.10.117', '62378' )
ORA-30683: failure establishing connection to debugger
ORA-12535: TNS:operation timed out
I am able to connect to database

I am using DBMS_FILE_TRANSFER.PUT_FILE() on a local Oracle Express instance to transfer a local file to a remote AWS RDS Oracle instance, but I am receiving the following error:
ERROR at line 1:
ORA-02019: connection description for remote database not found
ORA-06512: at "SYS.DBMS_FILE_TRANSFER", line 60
ORA-06512: at "SYS.DBMS_FILE_TRANSFER", line 168
ORA-06512: at line 2
I receive this error while executing the following SQL script:
BEGIN
DBMS_FILE_TRANSFER.PUT_FILE(
'DATA_PUMP_DIR',
'some_file.txt',
'DATA_PUMP_DIR',
'some_file.txt',
'MY_DATABASE_LINK'
);
END;
/
MY_DATABASE_LINK is a public database link located in my local Oracle Express instance:
CREATE PUBLIC DATABASE LINK MY_DATABASE_LINK CONNECT TO example_schema IDENTIFIED BY "example_user" USING '(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=example_host_info)(PORT=1521))(CONNECT_DATA=(SID=example_sid)))';
I'm fairly confident that the connection string behind the database link is correct, but I'm not sure how to be 100% sure.
The ORA-02019: connection description for remote database not found error does not make sense because the connection description is defined by the database link. It is not present in tnsnames.ora, and I am confident that it doesn't have to be for DBMS_FILE_TRANSFER.PUT_FILE() to work.
I am trying to establish a heterogeneous ODBC connection from an Oracle 21c XE database to a Progress OpenEdge 11.7 database. I have installed a 32 bit ODBC driver on the Windows 2019 server where the 21c XE DB resides. I have set up an ODBC System DSN, tested it and it works.
I created a initTIMEDATA.ora file in the C:\app\Administrator\product\21c\homes\OraDB21Home1\hs\admin folder.
It contains;
HS_FDS_CONNECT_INFO = TimeData
HS_FDS_TRACE_LEVEL = 4
HS_FDS_TRACE_FILE_NAME = TimeData.trc
Where TimeData matches the ODBC System DSN name.
I modified the listener.ora adding;
(SID_DESC=
(SID_NAME=TimeData)
(ORACLE_HOME=C:\app\Administrator\product\21c\dbhomeXE)
(PROGRAM=C:\app\Administrator\product\21c\dbhomeXE\bin\dg4odbc)
(ENVS = LD_LIBRARY_PATH=C:\Progressx86\OpenEdge\lib:C:\app\Administrator\product\21c\dbhomeXE\bin)
)
I modified my tnsnames.ora file adding;
TIMEDATA=
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=TCP)
(HOST=10.254.10.41)
(PORT=4621)
)
(CONNECT_DATA=
(SID=TimeData))
(HS=OK))
I created a DBLink like;
CREATE PUBLIC DATABASE LINK time_data_link CONNECT TO "sqluser" IDENTIFIED BY "myPassword" USING 'TIMEDATA';
After restarting everything (DB, Listener...) the listener shows;
Service "TimeData" has 1 instance(s).
Instance "TimeData", status UNKNOWN, has 1 handler(s) for this service...
When I try to run a query;
SELECT * FROM employee_view#time_data_link;
I get;
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from TIME_DATA_LINK
28545. 0000 - "error diagnosed by Net8 when connecting to an agent"
*Cause: An attempt to call an external procedure or to issue SQL
to a non-Oracle system on a Heterogeneous Services database link
failed at connection initialization. The error diagnosed
by Net8 NCR software is reported separately.
*Action: Refer to the Net8 NCRO error message. If this isn't clear,
check connection administrative setup in tnsnames.ora
and listener.ora for the service associated with the
Heterogeneous Services database link being used, or with
'extproc_connection_data' for an external procedure call.
Error at Line: 1 Column: 29
I see no errors in the listener.log, I cannot find TimeData.trc. In poking around the DB trace files I found a trace file related with multiple copies of;
HS connect: nscall returned status ffffffff (-1)

I have reached the end of my troubleshooting skills and hope someone else may be able to point me in the right direction.
I had two problems.
The TNSNAMES.ORA file needed to point to the Oracle DB server, running on localhost in my case. Once I changed this, the error changed to
Error;
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application {IM014}
New TNSNAMES.ORA;
TIMEDATA=
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=TCP)
(HOST=localhost)
(PORT=1521)
)
(CONNECT_DATA=
(SID=TimeData))
(HS=OK))
Once I saw this error it became apparent I needed the 64 bit version of the ODBC driver which I acquired.
After making these changes everything seems to work.

I am not able to execute this command, Even I am in system user. I tried with both that is in command prompt even in Oracle SQL developer tool.
When i am executing the below command in System user
execute dbms_connection_pool.start_pool();
I am getting error as
Error starting at line : 1 in command -
EXECUTE DBMS_CONNECTION_POOL.START_POOL()
Error report -
ORA-06550: line 1, column 7:

For your information I am user oracle express 12c
The database resident connection pool (DRCP) reduces the resource requirements of applications that currently don't support connection pooling, either because it is not supported by the application infrastructure, or it has not been implemented. DRCP is only supported for database connections using the OCI driver. The pool is managed using the dbms_connection_pool package. And the operation is started by start_pool procedure.
You can call this procedure in these two ways :
SQL> exec dbms_connection_pool.start_pool( pool_name => 'my_connection_pool');
or
SQL> exec dbms_connection_pool.start_pool;
but not like in the below way :
SQL> exec dbms_connection_pool.start_pool();
I had the same issue
conn / as sysdba
and
exec dbms_connection_pool.start_pool;
worked for me
and
SELECT connection_pool, maxsize
FROM dba_cpool_info;
to get the info about pool
