问题一：
ERROR at line 1: ORA-29538: Java not installed
解决方法
1.检查有没有安装JAVA组件
select * from v$option t where t.PARAMETER='Java';
如果返回行说明已安装，如果没有返回行，运行Oracle Universal Installer安装JAVA组件
2.如果在第1步返回行，则检查oracle中有没有dbms_java.
select distinct owner,name from dba_source where lower(NAME)='dbms_java';
如果没有返回行，执行第3步
3.在sqlplus下以sys登陆，执行$ORACLE_HOME/javavm/install/initjvm.sql
SQL>@?/javavm/install/initjvm.sql;
问题二：
ERROR at line 1:
ORA-29532: Java call terminated by uncaught Java exception:
java.security.AccessControlException: the Permission (java.io.FilePermission
/home/accmgrctl/src/server read) has not been granted to SQLVIEW. The PL/SQL to
grant this is dbms_java.grant_permission( 'SQLVIEW',
'SYS:java.io.FilePermission', '/home/accmgrctl/src/server', 'read' )
ORA-06512: at "SQLVIEW.PKG_FILE_API", line 1
解决方法：
这是由于oracle用户没有访问那个目录的权限，把源代码入在oracle有权限访问的目录下
或者用以下语句授权
EXEC Dbms_Java.Grant_Permission('oracle_username','java.io.FilePermission', '*','read ');

解决方法：
这是110202 上的又一新BUG(外部表的读取)
Need to replace the language specific (non-english) kup<lang>.msb file
with the english version.
1. cd $ORACLE_HOME/rdbms/mesg
2. Replace <lang> with your installed languages file.
mv KUP<lang>.msb to KUP<lang>.msb.BAK
3. Copy <us> version over current <lang> copy of kup msb file.
cp kupus.msb to KUP<lang>.msb
4. re-run the select against the external table
我实际的操作过程，就是：
该目录：$ORACLE_HOME/rdbms/mesg 下有两个文件：
kupzhs.msb 和 kupus.msb, 其默认使用了kupzhs.msb
此时，我把kupzhs.msb 重新命名为 kupzhs.msb.bak
之后在测试， OK：
