expdp导出数据,报错ORA-39064 ORA-29285错误,导致datapump的logfile记录的日志不全

. . 导出了 "HCP"."HR_ADJ_SAL_ADV_SETUP_M"                  0 KB       0 行
ORA-39064: 无法写入日志文件

查询数据库NLS_CHARACTERSET

SQL> select NAME, value$ from props$ where name like 'NLS_CHARACTERSET';

NAME
------------------------------
VALUE$
--------------------------------------------------------------------------------
NLS_CHARACTERSET
UTF8

查看客户端字符集


SQL> select userenv('language') from dual;

USERENV('LANGUAGE')
--------------------------------------------------------------------------------
SIMPLIFIED CHINESE_CHINA.ZHS16GBK

出现这个问题,是由于expdp本身调用UTL_FILE,在Oracle Database PL/SQL Packages and Types Reference中有When data encoded in one character set is read and Globalization Support is told (such as by means of NLS_LANG) that it is encoded in another character set, the result is indeterminate. If NLS_LANG is set, it should be the same as the database character set.
基于这样的情况,通过设置NLS_LANG在客户端字符集和服务端一致,就不会出现该问题

标题:增加默认值列exp DIRECT=Y导出,导入遭遇ORA-01400

最近的一次数据迁移中使用exp导出遭遇到ORA-01400: cannot insert NULL into 错误,凭着经验对其进行了重现,确定是由于增加默认值的列,使用DIRECT=Y 导出导致该问题
创建测试表
创建一张表,并且增加带默认值而且不为空的列,然后使用exp DIRECT=Y 导出数据

这里可以看到,故障已经重现ORA-01400: cannot insert NULL into,无法将空值插入到刚刚新加的默认值的列中

通过测试证明,对于11g新特性增加默认值,而且非为空的列,如果使用exp常规方法导入,再导出没有任何问题,如果使用DIRECT=Y特性,将导致导入失败(ORA-01400).这是由于11g的快速增加列和默认值且不为空的新特性导致的(直接修改字典,并没有真正的去修改数据底层存储).
查询mos发现匹配bug: Bug 13961541 : EXP WITH DIRECT=Y CAN NOT HANDLE ADD COLUMN DEFAULT NOT NULL FEATURE IN 11G

标题:impdp中的DISABLE_ARCHIVE_LOGGING参数测试

在oracle 12c版本中引入了impdp中的TRANSFORM中的DISABLE_ARCHIVE_LOGGING值,可以实现在导入的时候使用nologging处理从而减少日志量也增加速度,但是在force logging情况下该参数无效

标题:exp跳过某些表导出数据

有一个需求,某个用户有很多张表,但是只能使用exp导出,而且想跳过其中某几张表,其他对象包括依赖关系都需要。针对这样的情况,通过分析exp的视图脚本,在exu10tabs视图进行修改,跳过某些表即可

出现此类错误,也和自己的粗心有关系,没有仔细检查导出日志,另外该问题从10.1.0.2就有了,直到现在才发现,证明知识点欠缺.同样对于binary_float也有一样问题.

这里分析,未发现任何错误,导出程序直接报Segmentation fault终止

原因分析
通过各种方式导入都报类似错误,初步确定是dmp文件异常,而dmp异常有几种可能性:
1.exp程序异常导致dmp文件异常,这里使用tns方式导出,排除该种可能
2.数据库内存出现异常导致dmp文件异常,重启数据库依旧,排除该种可能
3.因为测试过多种平台,版本,本地,远程导入,排除兼容性,远程传输损坏等
4.因为以前正常,突然异常,坏可以exp程序调用包异常,这种故障不能排除

解决方案
鉴于此,通过expcat.sql重新安装相关包,发现执行这个之后,exp导出程序,再imp导入一切正常
执行catexp.sql不影响生产库,只影响exp/imp程序

conn / as sysdba
@?/rdbms/admin/catexp.sql

这里再次提醒我们看到exp导出成功,不能证明imp一定ok,最好通过imp进行导入测试

晚上十点多,准备睡觉了,一个朋友在qq上找到我,说他们数据库imp异常,希望我帮忙看看
大概情况
使用exp/imp升级并迁移数据库从win 10.2.0.1 升级到linux 11.2.0.3 由于硬盘空间不够,使用exp把win上面数据导出来,格式化掉win的数据文件所在硬盘格式化并加入到linux系统中(也就是说,故障之时,只有dmp文件,没有了数据文件),因为原库没有了,dmp又报错,所以担心了起来.

这里可以知道数据库exp的客户端是版本是10.2.0.1,使用编码是US7ASCII,但是导入的库编码是ZHS16GBK

这里我们可以知道数据库编码是ZHS16GBK,exp客户端编码为US7ASCII,因此到导出过程中发生了一次由ZHS16GBK到US7ASCII的编码转换
检查新库发现,其db编码为ZHS16GBK,新库的NLS设置为:nls_lang=AMERICAN_AMERICA.ZHS16GBK
整个导出流程是:db编码为ZHS16GBK的数据库被客户端编码为US7ASCII的exp导出,然后被编码为ZHS16GBK的imp导入到db编码为ZHS16GBK的数据库中
故障可能性定位
1.可能在从ZHS16GBK到US7ASCII的编码转换中发生数据异常,也就是说dmp文件本身异常(我们最不希望出现的结果)
2.由于数据库导出过场会发生编码转换(ZHS16GBK->US7ASCII),而导入过程未发生编码转换(ZHS16GBK->ZHS16GBK),从而出现异常
分析并解决
1. 使用dul扫描dmp文件发现汉字都能够识别,而且exp成功的记录条数在dul扫描中都完全正常恢复出来,证明dmp文件是正常的
2. 基于dmp文件正常,编码转换的过程,得出结论在该库的imp过程中设置nls_lang=AMERICAN_AMERICA.US7ASCII问题应该就可以正常解决.果不其然,设置了NLS_LANG之后imp导入数据OK
得出结论
1. 做升级,迁移尽快保留多一份数据,这次吓得不轻
2. exp/imp最好前后客户端编码一致,否则可能被转换晕
如果遭遇真的dmp损坏情况,类似:IMP-00098: INTERNAL ERROR: impgst2,可以联系我们,提供专业处理

ORACLE 12C 在datapump方面增强参数

标题:ORACLE 12C 在datapump方面增强参数

作者:惜分飞©版权所有[未经本人同意,不得以任何形式转载,否则有进一步追究法律责任的权利.]

在阅读ORACLE 12C datapump相关文档之时,发现有两个比较欣喜的参数LOGTIME和SQLFILE,鉴于他们是12C新增加参数,对他们的使用方法和用途进行简单说明
LOGTIME参数
该参数可以用于expdp/impdp,主要作用是记录执行步骤的开始时间,精确到微秒,使用语法为

LOGTIME=[NONE | STATUS | LOGFILE | ALL]
• NONE--No timestamps on status or log file messages (same as default)
• STATUS--Timestamps on status messages only
• LOGFILE--Timestamps on log file messages only
• ALL--Timestamps on both status and log file messages

该参数主要在我们对于一些数据库迁移升级项目使用datapump的时候,在测试阶段能够通过该参数发现哪一步执行时间较长,然后对其调优减少执行时间;另外一点就是可以通过做减法精确到具体的时间(毫米),我们可以知道我们的datapump主要耗时在哪一步,做到心中有数不慌

SQLFILE参数
该参数可以用于impdp,主要作用是未真实在目标端执行导入的情况下,生成sql文件包含该dmp文件的所有ddl语句,使用语法为

SQLFILE=[directory_object:]file_name

注意事项:
1.directory_object可以不和impdp的DIRECTORY参数不一致,如果是一样,directory_object可以省略
2.SQLFILE文件必须写入到磁盘之上,不能写入到ASM中
3.SQLFILE和QUERY参数冲突,不能同时使用
