SQL*Plus Error 57 Initializing SQL*Plus: Error Loading Message Shared Library

Root Causes

The most common causes for Error 57 are:

  1. Missing or incorrect LD_LIBRARY_PATH (Linux/UNIX) – The system cannot locate the Oracle shared libraries.
  2. Corrupt or missing Oracle Instant Client RPMs – Required packages like oracle-instantclient-basic and oracle-instantclient-sqlplus are not fully installed.
  3. Permission problems – The library files are not readable by your user.
  4. 32-bit vs 64-bit mismatch – Mixing 32-bit SQL*Plus with 64-bit libraries (or vice versa).

Solution 4: Update Library Versions

Ensure that the library versions used by SQLPlus are compatible with the Oracle database version. Root Causes The most common causes for Error 57 are:

ldd $ORACLE_HOME/lib/libsqlplus.so

If the library versions are not compatible, update them to the correct versions.

Recovery Procedures

Step 4: Verify Library Dependencies

# Check SQL*Plus binary dependencies (Linux)
ldd $ORACLE_HOME/bin/sqlplus

When Everything Else Fails: Reinstall Oracle Client


If you have exhausted all steps above and the error persists, your Oracle installation is likely beyond repair. The fastest resolution is often a clean reinstallation: SHLIB_PATH  on HP-UX


    

  1. Deinstall Oracle software (using deinstall or manual removal).
    2. 

  2. Reboot the system (to clear any cached library mappings).
    3. 

  3. Reinstall Oracle Client or Database software from the original installation media.
    4. 

  4. Re-apply any required patches.
    5. 

  5. Recreate your environment script (e.g., oraenv) carefully.
    6. 



1. Missing or Incorrect LD_LIBRARY_PATH (Linux/UNIX)


The dynamic linker uses LD_LIBRARY_PATH (or LIBPATH on AIX, SHLIB_PATH on HP-UX, LD_LIBRARY_PATH_64 on Solaris) to locate shared libraries. If $ORACLE_HOME/lib is not included, SQL*Plus cannot find libsqlplus.so.


Debian/Ubuntu


dpkg -S $ORACLE_HOME/sqlplus/mesg/sqlplus.msb
apt-get install --reinstall oracle-sqlplus
 oraenv ) carefully.
