Also, ensure the Oracle home directory tree is traversable:
# Add to System Environment Variables SET ORACLE_HOME=C:\app\oracle\product\19.0.0\dbhome_1 SET PATH=%ORACLE_HOME%\bin;%ORACLE_HOME%\lib;%PATH%
In Oracle’s error numbering system, within SQL Plus indicates a failure during the initialization phase. Specifically, SQL Plus cannot load its required message shared library – a special type of shared object file that contains localized error messages, prompts, and other linguistic resources. Also, ensure the Oracle home directory tree is
Then try running sqlplus /nolog . If that works, your NLS_LANG was misconfigured.
Incorrect file permissions can block library loading. Verify ownership and permissions: If that works, your NLS_LANG was misconfigured
SQL Plus Error 57 is an initialization error that occurs when the SQL Plus executable attempts to load a message shared library. The error message typically appears as follows:
Error 57 initializing SQL*Plus Error loading message shared library The error message typically appears as follows: Error
# RPM-based (Oracle Linux, RHEL) rpm -qf $ORACLE_HOME/sqlplus/mesg/sqlplus.msb rpm -V oracle-sqlplus # Verify package
This is the most common culprit on Linux. SQL*Plus needs to know where libclntsh.so and message libraries reside, which are located in the lib subdirectory of your Oracle Home.
