OracleDatabase12cRelease1(12.1.0.1.0)forLinuxx86-64OS:RedhatLinux5Update864bit1.按官方手册,启用 ..

Oracle Database 12c Release 1 (12.1.0.1.0) for Linux x86-64

OS: Redhat Linux 5 Update 8 64bit

 

1. 按官方手册,香港服务器,香港服务器,启用 varchar2 32k 支持

2. 使用 rman recover table 功能是,免备案空间,始终失败,报错如下:

RMAN-03015: error occurred in stored script Memory Script
RMAN-03009: failure of sql command on clone_default channel at 07/15/2013 13:03:14
RMAN-11003: failure during parse/execution of SQL statement: alter pluggable database  PDB1 open read only
ORA-14693: The MAX_STRING_SIZE parameter must be EXTENDED.

 

3. 在未启用 varchar2 32k 支持时, rman recover table 成功。

 

经过多位朋友测试,均和我测试结果一致,证明是  Oracle 12.1.0.1.0 的Bug.

 

详细测试过程如下:
