Summary
Trying to calculate statistics with DBMS_STATS.GATHER_SCHEMA_STATS or DBMS_STATS.GATHER_DATABASE_STATS and get the error
ORA-00600: internal error code, arguments: [smboPut:fixedlen2], [6], [7], [0], [69], [], [], []
Workaround
Set at the session level
sqlplus> ALTER SESSION SET "_newsort_enabled" = FALSE;
Try again to calculate the statistics. If it will work then set the hidden parameter permanent.
