谢谢Maclean,SEGMENT_TYPE是INDEX- SELECT tablespace_name, segment_type, owner, segment_name
- FROM dba_extents
- WHERE file_id = 13
- and 1842961 between block_id AND block_id + blocks - 1;
- TABLESPACE_NAME SEGMENT_TYPE OWNER SEGMENT_NAME
- --------------- --------------- ---------- ------------------------------
- MIS_INDEX INDEX YD PK_ACC_DAY_OPERATION_HIS
复制代码 重建索引- SQL> conn yd/******
- SQL> alter index PK_ACC_DAY_OPERATION_HIS rebuild online tablespace MIS_INDEX;
- Index altered
复制代码 但再次使用DBV仍出现Corrupt block relative dba- $ dbv file=+DATA/misora/datafile/mis_index4.dbf userid=system/sys

复制代码 再次定位这个块- SQL> SELECT tablespace_name, segment_type, owner, segment_name
- 2 FROM dba_extents
- 3 WHERE file_id = 13
- 4 and 1842961 between block_id AND block_id + blocks - 1;
- no rows selected
复制代码 请问这种情况,是出现了物理坏块吗? |
