Oracle12c32k与rmanrecovertable之间的Bug

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：

SQL> insert into t1 values(1);

1 row created.

SQL> insert into t1 values(2);

1 row created.

SQL> commit;

Commit complete.

SQL> select * from t1;

ID
———-
1
2

SQL> select to_char(sysdate,'yyyy-mm-dd hh24:mi:ss') from dual;

TO_CHAR(SYSDATE,'YY
