When I registered a database data store to ArcGIS Server in ArcCatalog, the following error occurs:
Underlying DBMS error[ORA-12154: TNS:could not resolve the connect
identifier specified No extended error.]
I set up the ArcGIS Server, ArcGIS for Desktop, and Oracle are all installed on one machine.
ArcGIS for Server 10.2.2 64bit
ArcCatalog 10.2.2 32bit
Oracle Instant Client 11.2.0 64bit
Oracle Database 11g Enterprise Edition 11.2.0 32bit
I have successfully made the Oracle 11g "Enabled Enterprise Geodatabase" through the ArcCatalog, and it seems nothing wrong.
Database Platfrom: Oracle
Instance: orcl
Authentication Type: Database authentication
User name: gesbar2
password: gesbar2
And I have added the Oracle Instant Client directory to the PATH and environment variable, I am sure that the 64-bit DLL is found before the 32-bit one.

Error Message
When creating a direct connect from ArcGIS Desktop installed on a computer installed with Windows 64-bit, the following error message is displayed:
"Failed to connect to the specified server. Underlying DBMS error[ORA-12154: TNS:could not resolve the connect identifier specified. No extended error.]"
Cause
This is a known issue with parentheses in install path names on the Windows 64-bit operating system.
Solution or Workaround
Perform one of the following workarounds:
Reinstall ArcGIS Desktop on a Windows 64-bit computer to a path that does not contain parenthesis. For example:
C:\Program Files\ArcGIS
Fix the bug on a 64-bit computer:
Download and install the Oracle 10g 32 bit client from Oracle.com. This installs version 10.2.0.1 of the client.
Download and install Oracle Patch Number 4547817, which is '10.2.0.2 Patch for Windows 32-bit'. This upgrades the client to version 10.2.0.2.
Download and install Oracle 32-Bit Patch Number 5383042. This patch fixes Oracle Bug 3807408:
Externally authenticated usernames containing a '(',')' or '=' cannot be authenticated, additionally if a program name / path contains these characters, it may not be possible to connect (ORA-12154).
