dbms_crypto.hash()
我在 Oracle 中使用函数时遇到问题。
我使用 sqlplus 作为“sys/passwd as sysdba”连接到数据库服务器,然后我安装了dbms_crypto
包:
@/home/oracle/app/oracle/product/11.2.0/dbhome_1/rdbms/admin/dbmsobtk.sql
@/home/oracle/app/oracle/product/11.2.0/dbhome_1/rdbms/admin/prvtobtk.plb
Grant execute on dbms_crypto to public;
Grant execute on dbms_sqlhash to public;
Grant execute on dbms_obfuscation_toolkit to public;
Grant execute on dbms_obfuscation_toolkit_ffi to public;
Grant execute on dbms_crypto_ffi to public;
一切看起来都不错,所以我测试了hash()
功能:
SQL> select dbms_crypto.hash(utl_raw.cast_to_raw('zorg'), 3) from dual;
DBMS_CRYPTO.HASH(UTL_RAW.CAST_TO_RAW('ZORG'),3)
--------------------------------------------------------------------------------
60C440F9954CA4744204CDA9CC93567059C1EC82
我以普通用户的身份断开连接并连接到该数据库,但随后出现错误:
SQL> select dbms_crypto.hash(utl_raw.cast_to_raw('zorg'), 3) from dual;
select dbms_crypto.hash(utl_raw.cast_to_raw('zorg'), 3) from dual

ORA-06521: PL/SQL: Error mapping function
ORA-06512: at "MN.DBMS_CRYPTO_FFI", line 131
ORA-06512: at "MN.DBMS_CRYPTO", line 72
为什么我不能以普通用户的身份使用此功能?如何允许其他用户使用它?
我与:
