ORA-12709: error while loading create database character set

What wrong?

SQL*Plus uses NLS files at $ORACLE_HOME/ocommon/nls/admin directory (pre 10g)

or $ORACLE_HOME/nls/ (10g and up), So have to verify:

- Verifify the ownership/permissions NLS files

- Verify the number of NLS files

Verify:

$ id

uid=200(oracle) gid=200(oinstall) groups=200(oinstall),201(dba)

$ cd $ORACLE_HOME/nls/

bash: cd: $ORACLE_HOME/nls/ : Permission denied

So, changed permmision in $ORACLE_HOME/nls path and verified every directories + files in $ORACLE_HOME/nls/*, that "oracle" user can access...

startup database again:

SQL> startup

ORACLE instance started.

Database mounted.

Database opened.
