I have tried so many thing but i can't resolve that Error.
I can connect with my username and password to:
Database in SQLDeveloper,
in SQL-Plus,
in Server-Explorer (Visual Studio 2008)
and all works fine.
But if i Compile my Project i get that Error:
ORA-1017: invalid username/password; logon denied
Why is that?
I tried to set case_sensitive to false, but the same error appears.
I don't know what else to do.

We have Oracle 19c Client installed in our application Unix server.
When we connect to a 19c Database server from our application Unix server, it is working as expected.
But when we try Connecting 11gR2 Database schema using sqlplus from our application server, getting the error ORA-12650 : No Common Encryption or data integrity algorithm
From our application Unix server, we did a tnsping with the connect descriptor we had used. TNSPING is working fine from our application server.

Oracle 11gR2 only supports the SQLNET.CRYPTO_CHECKSUM_TYPES_SERVER value SHA1. See documentation here: https://docs.oracle.com/cd/E11882_01/network.112/e40393/asoappa.htm#ASOAG9780.
If you want to make a TCPS connection to the 11.2 database, you're going to have to include SHA1 in the list of SQLNET.CRYPTO_CHECKSUM_TYPES_CLIENT values on your 19c client, and see that the server sqlnet.ora is similarly configured. Note that use of SHA1 has been considered insecure since at least 2016.

SQLNET.CRYPTO_CHECKSUM_TYPES_CLIENT = (SHA256, SHA1)

SQLNET.CRYPTO_CHECKSUM_SERVER = REQUIRED

Also note that per Oracle Support Doc ID 207303.1 your 11gR2 database must be at least version 11.2.0.3 or 11.2.0.4 to support a 19c client. Previous releases (e.g. 11.2.0.1) do not support the 19c client at all.

Thank you #pmdba for your guidance.
Is there is any command to find my installed oracle version from windows command prompt. (just like java -version..)
You need to locate ORACLE_HOME directory, to set it as environment variable and then to run opatch:
set ORACLE_HOME=...
"ORACLE_HOME"\OPatch\opatch lspatches
This command lists the installed patches with the Oracle major version.
You can use the below to get the database version by navigating to the ORACLE_HOME directory
$ORACLE_HOME\OPatch\opatch lsinventory | find "Oracle Database"
Well, that depends on what you really have.
If you have installed Oracle onto your PC (such as my 11gXE), then you could try sqlplus -v:
c:\Temp>sqlplus -v
SQL*Plus: Release 11.2.0.2.0 Production
11.2.0.2.0; is that really so?

Yes, it is. I use SQL*Plus 11.2.0.2.0 which connects me to 11.2.0.2.0 database.
However, if I don't have Oracle installed on my PC but it is somewhere on database server and I access it via network, then it won't work because it'll display SQL*Plus (i.e. client installed on my PC), not database version. Besides, I can have several clients installed, so it depends on which sqlplus executable I ran.
Database version - in such a case - can't be retrieved from operating system command prompt only (at least, I don't know how to do it). You can obtain it by connecting to the database itself, e.g.
Client version:
M:\>sqlplus -v
SQL*Plus: Release 11.2.0.1.0 Production
ORCL database version is 11.2.0.4.0

I need to import a database backup from Server 1 to Server 2. I have tried this.
Export From Server 1:
EXPDP Username/Password#xe DIRECTORY=CUSTOM_DIR SCHEMAS=PRICE DUMPFILE=PRICE.DMP
Import To Server 2:
IMPDP Username/Password#\"(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=Test)(PORT=1500)))(CONNECT_DATA=(SID=TESTSID)))\" DIRECTORY=CUSTOM_DIR DUMPFILE=TEST.DMP TABLE_EXISTS_ACTION=REPLACE LOGFILE=TEST.LOG
While importing, i am getting the exception as,
Copyright (c) 1982, 2013, Oracle and/or its affiliates. All rights reserved.
UDI-00018: Data Pump client is incompatible with database version 11.2.0.1.0
Is that not possible to import the backups between different versions.?
Yes, it is possible. You need to supply the "version" parameter on the export, and specify 11.2.0.1. This will instruct expdp to create a dmp file that is compatible with that version. See expdp command reference
I tried to use Oracle Database 12g Data Pump to import dump file inside a Oracle 11g Database. The return i got was UDI-00018: Data Pump client is incompatible with database version 11.2.0.4.0 .
The cause is: Two Oracle Homes in different versions, and the expdp/impdp called is wrong (verify path variable).
This may be occuring with you. You have another $ORACLE_HOME in your environment, and the data pump called is from this environment. Verify your .bash_profile or .profile files and set the correct environment.
I'm using Instant-Client 12.1.0.2.0, connecting to a 12.1.0.1.0 (Linux) server, in Multi-Tenant configuration.
Using either:
SQL*Plus
OCILogon2
OCIServerAttach + OCISessionBegin(OCI_RDBMS credentials, OCI_DEFAULT mode)
I can connect (using EZCONNECT, no environment variables at all) from a client machine to a PDB on the server, using SYSTEM. E.g.
c:\>sqlplus system#'//host/pdb12c_1.domain.net'

I've modified my OCI application to use OCI_SYSDBA as the mode to OCISessionBegin, and it fails the same way. I've tried SYSOPER with both SQL*Plus and my OCI client app, and it also fails the same way.
What am I missing? What kind of restriction are placed on connection that want to gain SYSDBA? Is this mode impossible from a client machine? Or is that because I connect to a PDB instead of the CDB?
I'd appreciate some insights. Thanks.
PS: yes, I double and triple checked I typed the password in correctly
c:>sqlplus system#'//host/pdb12c_1.domain.net' as SYSDBA
You are using SYSTEM user which is incorrect. You need to use SYS.

I'm trying to import a schema using data pump. Here's my problem: I can only access the impdp utility on the source DB server, but it's version 11.1, and the target DB version is 11.2, so if I run the import, I got an error:
UDI-00018: Data Pump client is incompatible with database version 11.01.00.06.00
I want to work around this by using my laptop, installed with the Oracle express version 11.2, same version as the target DB, by using this command:
impdp username/password#targetDB directory=data_pump_dir network_link=sourceDB schemas=EMP
In this command, targetDB is a public db link created on my local oracle, and the same record has been added to tnsnames.ora; sourceDB is a public db link created in the target DB, pointing to the source DB.
But I got this error:
Connected to: Oracle Database 11g Release 11.2.0.2.0 - 64bit Production
ORA-39001: invalid argument value
ORA-39200: Link name "sourceDB" is invalid.
ORA-12170: TNS:Connect timeout occurred
The source DB version is:
Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - 64bit Production PL/SQL Release 11.1.0.6.0 - Production
CORE 11.1.0.6.0 Production
TNS for 64-bit Windows: Version 11.1.0.6.0 - Production
NLSRTL Version 11.1.0.6.0 - Production
The target DB version is:
Oracle Database 11g Release 11.2.0.2.0 - 64bit Production
PL/SQL Release 11.2.0.2.0 - Production
CORE 11.2.0.2.0 Production
TNS for Linux: Version 11.2.0.2.0 - Production
NLSRTL Version 11.2.0.2.0 - Production
My local DB version is:
Oracle Database 11g Express Edition Release 11.2.0.2.0 - Production
PL/SQL Release 11.2.0.2.0 - Production
CORE 11.2.0.2.0 Production
TNS for 32-bit Windows: Version 11.2.0.2.0 - Production
NLSRTL Version 11.2.0.2.0 - Production
So what did I do wrong?
Is there a way to import from the source to target?
It looks like you cannot access your local database remotely:
In order to avoid
ORA-12170: TNS:Connect timeout occurred
Is to make sure that you are able to connect to the remote database.
I advise you start making sure it works with a simple query accessing the db-link:
SQL> select * from dual#sourceDB;
Another solution
Another solution to your problem is to specify the target version of the export file at the time you export it, e.g. with:
version=11.1
