Q: IMP-00032: SQL statement exceeded buffer length

Ans:

#> imp system/oracle buffer=1000000 .....
    If it's still not working, try to find out the value of the SQL_LENGTH with the following command:

In the source DB you need to run

SQL> select dbms_lob.getlength (dbms_metadata.get_ddl('TABLE','<table-name>','<owner-name>')) "SQL_LENGTH" from dual;
   
    SQL_LENGTH
    ----------
     71203

NOTE: the table name can be one of the tables failed on import.

2. Extend the datafile in the temporary tablespace
3. Re-export the dump file from the source DB and enable the option compress=n.
