ERROR at line 1:
ORA-01996: GRANT failed: password file
'/u01/app/oracle/product/11.2.0.1/db_1/dbs/orapworcl' is full
果然出现报错！
由此来看， 官方文档中所说的 “if your operating system block size is 512 bytes, it holds four password entries. The number of password entries allocated is always a multiple of four” 确实没错！
