ORA-01172: recovery of thread 1 stuck at block 3024 of file 19

ORA-01151: use media recovery to recover block, restore backup if needed

Cause: 

This error usually means that blocks of file 19 are corrupted, In this case we need to recover file 19.

Crash recovery or instance recovery could not apply a change to a block because it was not the next change. 

This can happen if the block was corrupted and then repaired during recovery.

SOLUTION :- 

We need to recover all of corrupted block by using data file recovery or Database recovery. 

In my case I have recover datafile 19.

SQL>  recover datafile 19;

Media recovery complete.

SQL> alter database open;

Database altered.

SQL> select name,OPEN_MODE from v$database;

NAME      OPEN_MODE
