BR0398E DBVERIFY detected corrupted blocks in TS SAPSR3

Question

Hi!
After DBVerify I get the following error:
BR0398E DBVERIFY detected corrupted blocks in /oracle/<sid>/sapdata4/sr3_8/sr3.data8
Furthermore I get the following warning/information:
Completely zero block found during dbv:
Page 286685 is marked corrupt
Question:
1) Does it mean that my database is corrupt and should be recovered from a valid backup?
2) What is the approach to handle here and to solve the error?
Enclosed the output of the following SQL commandos:
> select dbms_utility.data_block_address_block(1522735858) from dual;
DBMS_UTILITY.DATA_BLOCK_ADDRESS_BLOCK(1522735858)
                                           203506
> select dbms_utility.data_block_address_file(1522735858) from dual;
DBMS_UTILITY.DATA_BLOCK_ADDRESS_FILE(1522735858)
                                             363
> select file#, rfile# from v$datafile where name = '/oracle/<sid>/sapdata4/sr3_8/sr3.data8';
     FILE#     RFILE#
        11         11
> select segment_name, partition_name, segment_type, block_id, blocks   from dba_extents   where (203506 between block_id and (block_id + blocks - 1))   and file_id = 363 and rownum<2;
no rows selected
Thank you very much!

Hi!
Some additional information
SQL> SELECT dbms_utility.data_block_address_block(1522735858) "BLOCK", dbms_utility.data_block_address_file(1522735858) "FILE" FROM dual;
     BLOCK       FILE
    203506        363
After this I executed alter system dump commando:
> alter system dump datafile 363 block 203506;
When I open the generated dump file I can see:
Error: alter system dump datafile/tempfile: invalid input file # 363
SQL>  select owner, segment_name, partition_name, segment_type, block_id, blocks
  2  from dba_extents  
  3 where (525 between
  +4  block_id and (block_id + blocks - 1))+
  5  and file_id = 4
  6  and rownum < 2;
OWNER SEGMENT_NAME PARTITION_NAME   SEGMENT_TYPE         BLOCK_ID     BLOCKS
SAPSR3                    DD08T~0                   INDEX                           521        128
Question
Should I run the following SQL commando or how can I solve my problem?
ALTER INDEX DD08T~0 REBUILD ONLINE;
