Need advice on ORA-01578: ORACLE data block corrupted
We have a development database server version- 10.2.0.3 with materialized views refresh as complete every morning. Yesterday we had a power failure and the server went down and database was shutdown unexpectedly.
When we restarted the database after the server restarted, we found some of the datablocks got corrupted . Following were the exceptions that we saw in the alert.log.
Errors in file /i01_01/app/oracle/product/10.2.0/db_1/admin/orcl9/bdump/orcl9_smon_7547.trc:
ORA-01578: ORACLE data block corrupted (file # 11, block # 257712)
ORA-01110: data file 11: '/i01_01/app/oracle/product/10.2.0/oradata/orcl9/ts_gen_data_02.dbf'
ORACLE Instance orcl9 (pid = 8) - Error 1578 encountered while recovering transaction (9, 38) on object 54463
I tried the following query to see the segment type.
select owner, segment_name, segment_type from dba_extents where file_id =11 and 257712 between block_id and block_id + blocks - 1;
OWNER
------------------------------
SEGMENT_NAME

SEGMENT_TYPE

VISH
INVENTORY_TXN
TABLE
where " INVENTORY_TXN " is a materialized view that was using the block that got corrupted. I can always recreate the MV by dropping and recreating it. Will it solve the problem???
If not, how can I recover/repair the block.???
Can anyone advice on this. Thanks very much in advance.
