When specifying a JDBC EZConnect URL to include the Protocol, for example:
jdbc:oracle:thin:#tcps://example1.com:1522/my_service_name
jdbc:oracle:thin:#tcp://example1.com:1522/my_service_name
I am getting the error "Status : Failure - Test Failed: IO Error: Invalid number format for port number"
I am following the example page XXX of the Oracle 19c JDBC Developers Guide (http://ora-srv.wlv.ac.uk/oracle19c_doc/jjdbc/jdbc-developers-guide.pdf)
Does anyone have any input into why this error is occurring ?
Thanks

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)
ns main err code: 12569
ns (2) err code: 0
nt main err code: 0
nt (2) err code: 0

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.
when I run this command from Hive shell in our EMR cluster:
CREATE EXTERNAL TABLE my_db.my_table
(col1 string, ...)
STORED BY 'org.apache.hadoop.hive.dynamodb.DynamoDBStorageHandler'
TBLPROPERTIES (
"dynamodb.table.name" = "table_name",
"dynamodb.column.mapping" = "col1:col1 ... "
);
I get the following error:
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. MetaException(message:Got exception: org.apache.hadoop.net.ConnectTimeoutException Call From ip-xx-xx-xx-xxx.ec2.internal/xx.xx.xx.xxx to ip-yy-yy-yy-yyy.ec2.internal:8020 failed on socket timeout exception: org.apache.hadoop.net.ConnectTimeoutException: 20000 millis timeout while waiting for channel to be ready for connect. ch : java.nio.channels.SocketChannel[connection-pending remote=ip-yy-yy-yy-yyy.ec2.internal/yy.yy.yy.yyy:8020]; For more details see: http://wiki.apache.org/hadoop/SocketTimeout)
The EMR cluster is in VPC.
I Tried editing the Inbound/Outbound rules of the security group of the master node, so far with no success.
Thanks, Michael
AWS Support were able to assist me: the problem was that the database location in Glue was pointing to old HDFS address ip-yy-yy-yy-yyy.ec2.internal (different then xx.xx.xx.xxx), according to the master's node of the previous cluster. I changed to location to point to S3 and the problem was resolved.
Using Oracle JDBC driver with TNS-alias instead of host:port:SID a'la
jdbc:oracle:thin:#TNS_ALIAS
you may get this error message
java.sql.SQLRecoverableException: I/O-Error: Unknown host specified
while calling
java.sql.DriverManager.getConnection
But there is no problem with the hostname specified by TNS-alias.
Sadly this error message does not point to the real reason:
The error occurs if driver cannot find the tnsnames.ora config file.
Solution
You have to ensure that system-property "oracle.net.tns_admin" is set before connecting and points to the directory containing the tnsnames.ora.
