现场测试工程师在半夜电话反馈:在新建的小测试库做XTTS流程验证,遇到错误:
ERROR at line 1: ORA-20001: TABLESPACE(S) IS READONLY OR, OFFLINE JUST CONVERT, COPY ORA-06512: at line 284
先了解具体阶段:
具体是最后表空间read only后,执行最后一次增量备份就会报这个错;
现场参与测试人员初步分析给出方向:
这个284行那个报错xtts的官方文档说可以忽略,但问题是遇到这个报错就退出来了,没有生成备份相关文件。
实际我去查MOS,在官方的V4 XTTS文档中:
Prerequisites 部分有提到:
The tablespace must be in READ WRITE at the first backup, (level 0) otherwise, the following errors will occur: RMAN> DECLARE 2> * 3> ERROR at line 1: 4> ORA-20001: TABLESPACE(S) IS READONLY OR, 5> OFFLINE JUST CONVERT, COPY 6> ORA-06512: at line 284 7> 8> 9> RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-00558: error encountered while parsing input commands RMAN-01006: error signaled during parse RMAN-02002: unexpected end of input file reached
可以看到这个错误并不能忽略,而是对应XTTS测试的表空间,要做过level 0的备份,否则就会报这个错误。
所以解决方案就是要在读写模式下做一次level 0的备份。再去做xtts的测试。
