Oracle Database 12c Release 1 (12.1.0.1.0) for Linux x86-64
OS: Redhat Linux 5 Update 8 64bit
1. 按官方手冊,啟用 varchar2 32k 支援
2. 使用 rman recover table 功能是,始終失敗,報錯如下:
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. 在未啟用 varchar2 32k 支援時, rman recover table 成功。
經過多位朋友測試,均和我測試結果一致,證明是 Oracle 12.1.0.1.0 的Bug.
詳細測試過程如下:
