This paper provides an in-depth exploration of the ORA-12154 error in Oracle database connections within the PLSQL Developer environment. When users can successfully connect to the database via SQL*Plus command line and tnsping utility, but PLSQL Developer reports TNS inability to resolve the connect identifier, the issue often stems from application file access permission restrictions. By analyzing the solution mentioned in the best answer—moving PLSQL Developer from the "Program Files (x86)" folder to the "Program Files" folder—this paper reveals the impact mechanism of program file directory permissions on Oracle network configuration file reading in Windows systems. The article explains in detail the working principles of tnsnames.ora and sqlnet.ora files, the differences in configuration file reading strategies between PLSQL Developer and SQL*Plus, and how to ensure applications can correctly access necessary TNS configurations by adjusting installation locations or configuring environment variables. Additionally, it provides systematic troubleshooting steps, including validating TNS configurations, checking environment variable settings, and confirming network service name resolution order, helping readers fundamentally understand and resolve such connection issues.
