asm disk 大小限制

发表于 2018 年 8 月 24 日 由 惜分飞

这个问题在12C之前争议很小,基本共识非XD环境不能超过2T,但是到了后面的版本中,发生了一些改变,主要是COMPATIBLE.ASM and COMPATIBLE.RDBMS disk group attributes are set to 12.1 or greater的时候asm disk 大小限制依赖au size,
1M ausize asm disk limit为4 PB
2M ausize asm disk limit为8 PB
4M ausize asm disk limit为16 PB
8M ausize asm disk limit为32 PB
asm-limit-1
asm-limit-2

参见:Oracle ASM Storage Limits
18C中COMPATIBLE.ASM和COMPATIBLE.RDBMS默认值（COMPATIBLE.RDBMS为10.1,也就是说默认情况下非XD情况还是只能支持不超过2T的asm disk）

增加默认值列exp DIRECT=Y导出，导入遭遇ORA-01400

发表于 2018 年 8 月 21 日 由 惜分飞

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

使用常规导出

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

--------------------- Binary Stack Dump ---------------------

根据Catupgrd.sql Fails with ORA-3113/ORA-7445 During Grant Select On ALL_JOBS to Public with Grant Option (Doc ID 419309.1)文档,处理建议

1. Make sure LD_LIBRARY_PATH or LIBPATH is set correctly:
  AIX
  ====
  export LIBPATH=$ORACLE_HOME/lib:$LIBPATH

  HP-UX
  =====
  export LD_LIBRARY_PATH=$ORACLE_HOME/lib
  export SHLIB_PATH=$ORACLE_HOME/lib32

  HP Tru-64
  ========
  export LD_LIBRARY_PATH=$ORACLE_HOME/lib

  SUN Sparc Solaris-64Bit
  ==================
  export LD_LIBRARY_PATH_64=$ORACLE_HOME/lib
  export LD_LIBRARY_PATH=$ORACLE_HOME/lib32

  SUN Sparc Solaris-32Bit
  ==================
  export LD_LIBRARY_PATH=$ORACLE_HOME/lib

  Linux
  =====
  export LD_LIBRARY_PATH=$ORACLE_HOME/lib

2. Make sure ORA_NLS parameter  is set correctly. See the following notes for assistance:

Note 77442.1  (ORA_NLS32, ORA_NLS33, ORA_NLS10) Environment Variables explained.

3. Make sure Listener is also started with the correct environment variables if you were doing 
  remote connection from client through sqlnet rather than local connection to database.

4. Shutdown the database and rerun the upgrade:

SQL> SHUTDOWN IMMEDIATE
SQL> STARTUP UPGRADE
SQL> SPOOL patch.log
SQL> @?/rdbms/admin/catupgrd.sql
5.  If the above failed then it might be due to the libjox *.a file is not replaced during upgrade or install.

检查该环境发现libjox动态库丢失
libjox

由于软件升级不正常,导致数据库升级出现该问题,在升级软件过程中,一定检查升级软件和升级结果
