【Oracle】逻辑备份失败ORA-39002,39070,29283,06512
查看备份邮件的时候，发现逻辑导出失败，日志如下：

expdp 导出备份都出现一样的错误：
ORA-39070: Unable to open the log file.显示打不开directory，怀疑和此directory指定的路径有关：
根据脚本查看备份directory路径：
expdp system/pwd SCHEMAS=dwdss filesize=8000m directory=mydp1 logfile=${EXPDP_LOG} parallel=8 .....
查看路径权限信息：
ops$admin@RAC1>SELECT directory_name, grantee, privilege
2 FROM user_tab_privs t, all_directories d
3 WHERE t.table_name(+)=d.directory_name
4 ORDER BY 1,2,3;
DIRECTORY_NAME GRANTEE PRIVILEGE

BACKUP_DW
DIR_FOR_EXP_DW
DIR_FOR_EXP_DW_INS2
MYDP1
ops$admin@RAC1>exit
查看DIRECTORY_NAME， DIRECTORY_PATH
ops$admin@RAC1>select * from dba_directories;
OWNER DIRECTORY_NAME DIRECTORY_PATH

admin@RAC1:/netapp/dwnew/backup>cd /netapp/asoftdw/backup
-bash: cd: /netapp/asoftdw/backup: 没有那个文件或目录
由于没有/netapp/asoftdw/backup 这个目录导致逻辑备份失败。
解决方法：
增加/netapp/asoftdw/backup 路径，或者建立新的directory 并修改脚本中关于directory=mydp1
-------------------------------------------------------------------------
遇到这样错误还有如下情况，
都是和directory相关的！
1 系统的oracle 用户没有对directory的读写权限，所有oracle的进程包括expdp也不能对directory指定的目录进行读写。
解决方法：
检查directory所指定的目录的权限，并赋予正确的权限
2 对于rac系统，在执行expdp时使用tns连接名：
expdp system/xxxx@db directory=xxxxxxxxxx dumpfile=xxxxxxxx.dmp logfile= xxxxxxx.log schemas=xxxxxx

ORA-29283: invalid file operation
ORA-06512: at "SYS.UTL_FILE", line 536
ORA-29283: invalid file operation
原因：对于rac 系统TNS name 是一个负责均衡的连接字符串，当指定TNS name连接时，expdp程序可能指向另外一个没有对应目录或者目录不可共享的实例从而导致报错。
解决办法：对于rac 系统不要指定tns 名称
3 directory 对于的系统目录路径不存在，也就是我遇到的情况
遇到此类问题可以执行下面的语句,检查directory的权限和具体os对于路径
SET lines 80
COL grantee FORMAT a20
COL privilege FORMAT a10
SELECT directory_name, grantee, privilege
FROM user_tab_privs t, all_directories d
WHERE t.table_name(+)=d.directory_name
and d.directory_name='DIRECTORY_NAME'
ORDER BY 1,2,3;
set linesize 120
col owner for a15
col DIRECTORY_path for a60
col DIRECTORY_NAME for a25
select * from dba_directories ;
