Fix ORA-01139: RESETLOGS option only valid after an incomplete database recovery

While shutting down my TEST database process was hanged. Then I had to use shutdown abort. But when I wanted to start database it did not open.


 SQL> select name from v$database;

 What`s wrong?

Tried to reset logs

SQL> alter database open resetlogs;  
 alter database open resetlogs

 ERROR at line 1:  
 ORA-01139: RESETLOGS option only valid after an incomplete database recovery 

Unsuccessful...
Let`s recover database 

SQL> recover database until cancel;  
 Media recovery complete.  

Now, try to open with resetlogs

 SQL> alter database open resetlogs;  
 Database altered. 


Done, now it works

ORA-29339: tablespace block size 16384 does not match configured block sizes

While I create non standart db_block_size tablespace I faced ORA-29339: tablespace block size 16384 does not match configured block sizes.

16k = 16*1024 = 16384

 SQL> CREATE TABLESPACE DATA DATAFILE

Check db_*k_cache_size parameters

 SQL> show parameter db_block_size

I need to set db_16k_cache_size.
 SQL> alter system set db_16k_cache_size = 128M scope=both; 


Then try again


 SQL> CREATE TABLESPACE DATA DATAFILE  
  '/u01/app/oracle/oradata/cdb1/TEST/data01.dbf' SIZE 100M AUTOEXTEND ON NEXT 10M MAXSIZE 31G

 FLASHBACK ON;  
 Tablespace created.

Fix: ORA-13639: The current operation was interrupted because it timed out.

Sometimes SQL Tuning Advisor interrupts cause time limit took more than defined. You have to analyze it or increase value. Here you can see increasing of value.

Example result of sql

select
                 execution_name, advisor_name,
                 to_char(execution_start,'dd-mon-yy hh:mi:ss') execution_start,
                 to_char(execution_end,'dd-mon-yy hh:mi:ss') execution_end, status,error_message
from dba_advisor_executions
where task_name = 'SYS_AUTO_SQL_TUNING_TASK'
order by execution_start;



Check value of TIME_LIMIT`s parameter :

SQL> column parameter_value for A35   
 SQL> select   
      parameter_name, parameter_value   
      from dba_advisor_parameters   
      where task_name = 'SYS_AUTO_SQL_TUNING_TASK'   
      and parameter_name in ('TIME_LIMIT',   
                            'DEFAULT_EXECUTION_TYPE',   
                            'LOCAL_TIME_LIMIT'); 
 
 PARAMETER_NAME                 PARAMETER_VALUE  
 ------------------------------ ------------------------------  
 LOCAL_TIME_LIMIT                1200  
 TIME_LIMIT                      3600  
 DEFAULT_EXECUTION_TYPE          TUNE SQL  

In our case it is default value. Let`s increase it

 SQL> begin   
 DBMS_SQLTUNE.SET_TUNING_TASK_PARAMETER(task_name => 'SYS_AUTO_SQL_TUNING_TASK', parameter => 'TIME_LIMIT', value => 7200);   
 end;   
 / 2  3  4   
 PL/SQL procedure successfully completed. 

Check again:
 PARAMETER_NAME,             PARAMETER_VALUE  
 LOCAL_TIME_LIMIT,           1200  
 TIME_LIMIT,                 7200  
 DEFAULT_EXECUTION_TYPE,     TUNE SQL
