Server Administration :: ORA-19821 / Intentionally Corrupt Log File Was Found
Aug 15, 2011
don't know if I can repeat it. It occured while converting a database to archivelog mode, after completing a Data Pump export/import upgrade from 11.1.0.7. I fixed it like this: juno> startup mount;
ORACLE instance started.

Database mounted.
juno> alter database archivelog; alter database archivelog
ERROR at line 1: ORA-19821: an intentionally corrupt log file was found
juno> recover database until cancel; Media recovery complete.
juno> alter database open resetlogs;

I am trying to have sqlldr running against a file:
C:oratest20080318
Is it possible I get SQL*Loader-500: Unable to open file and 503 file not found just because the file name does not have an extension?
I can see that any file name I try it looks after whateverFileName.dat! Is there a way to have sqlldr working with files that do not have extensions?

I've recently moved jobs and am doing a lot of the normal things getting familiar with my new company's databases.I was checking through our production backup logs and came across something that looks a little funny. From the last two days backups, I see:
select completion_time, marked_corrupt, media_corrupt, logically_corrupt
from v$backup_datafile
where controlfile_type = 'B'
order by completion_time desc
COMPLETION_TIME MARKED_CORRUPT MEDIA_CORRUPT LOGICALLY_CORRUPT
01/12/2011 11:27:252011 1201 2

The 01:40 record will come from our nightly command:
BACKUP INCREMENTAL LEVEL=0 FILESPERSET=20 FORMAT 'full_%d_%t_%s_%p'
DATABASE INCLUDE CURRENT CONTROLFILE
The 11AM records will come from the command:
BACKUP INCREMENTAL LEVEL=0 FORMAT 'ctl_%t_%s_%p' CURRENT CONTROLFILE;
(I know backups shouldn't still be running at 11am and we don't need level 0 backups every night, that's a seperate issue I'll be addressing! ) I see there's been a similar entry here in v$backup_datafile for all backups that there's records for. The database is up and running just fine. There are no unusual errors being reported by the database in OEM or the alert log.I tried looking at both our control files (yes, should have 3 - something else I've listed to change!) with dbverify which showed no issues - though I'm not sure if this is designed to work with control files.
If so, how could I confirm whether it's an issue with a specific controlfile (I'm assuming it's not an issue with the backup to tape itself, as it's reporting the same corruption every day)?I'd obviously like to diagnose this now while the db is up and running, rather than at 4am some morning during a crash and finding out my backup control files are no good!

I have a database where view v$database_block_corruption shows a corrupted block
SQL> select * from v$database_block_corruption;
FILE# BLOCK# BLOCKS CORRUPTION_CHANGE# CORRUPTIO
---------- ---------- ---------- ------------------ ---------
4 756652 1 5.5157E+12 CORRUPT
I am not able to get the relevant segment from the above information
SQL> select segment_name, segment_type, owner
2 from dba_extents

4 and 756652 between block_id
5 and block_id + blocks -1;
no rows selected

DBVERIFY - Verification complete
Total Pages Examined : 3932160
Total Pages Processed (Data) : 3119107
Total Pages Failing (Data) : 0
Total Pages Processed (Index): 755048
[code]....
I have uploaded the complete logfile.
Below is a part of logfile
DBVERIFY - Verification starting : FILE = /prd/dvp/ora/oradata/LHF/disk06/gds_t01_01.dbf
Block Checking: DBA = 21728172, Block Type = KTB-managed data block
**** kdxcoavs = -84 < 0, avail = 3129
---- end index block validation
Page 756652 failed with check code 6401
##not here that 756652 is the same block# mentioned in v$database_block_corruption
here i tried finding the OBJECT ID as below
SELECT dbms_utility.data_block_address_block(21728172) "BLOCK", dbms_utility.data_block_address_file(21728172) "FILE" FROM dual;
BLOCK FILE
---------- ----------
756652 5
Now for the same BLOCK it is giving different File, again the segment_name or segment_id could not be found from the above information.

I noticed my DB is generating a lot of "small" .arc files and I am usure why. As you can see from the v$log query my log file size is set to 50MB. But yet BLOCKS*BLOCK_SIZE never adds up to 50MB.
Is there anything else I can look into to see how to make the .arc files larger?

I am trying to create a new controlfile. I used "alter database backup controlfile to trace;" and then I copied and pasted the contents of the trace file into the .sql file. My sql script is

MAXDATAFILES 100

Actually, the name of my database was 'STAR' and I changed it to "FIVESTAR" int this .sql script. Now when I run this script with SQL> @ <path of my sql script>, it gives me the following errors:

I was doing some R&D on my test machine trying to understand how controlfile works. I started up my db and then deleted (renamed)the controlfiles at OS level. I was expecting the db to shutdown. But it dint. Moreover when i queried select name from v$controlfile; it was still reflecting the old controlfile names. To check if it was still functioning, i created a new tablespace with one file and it also got created without any error.
What i dint understand is how could the db still be running when the control file was'nt there and new tablespace and datafile get created? As i understand, whenever a new file is created, an entry is made in the control file. But when control file dint exist where was the data about new tablespace and datafile written?

Not able to understand what's wrong with the code. I am trying to import data to a table using a CSV file. I have exported the data (CSV) from the interactive report and I am just trying to insert the same data to the table, through a process. When, I tried to do so; its throwing an error message saying NO_DATA_FOUND and file is not getting inserted into wwv_flow_files table.
But when I removed the data from the CSV file for the comments field and then tried importing the file, the process worked. I don't understand whats the problem with the code.
I have a sample app setup in my workspace for this weird problem.

Workspace details:
CSV file with comments field and data in it - when trying to import - throws an error message NO_DATA_FOUND
CSV file with comments field and without data in it - tried importing - this worked

I mistakenly added a datafile to a tablespace which is asm, however the datafile was created in a default location and not the asm location:
alter tablespace pdaiidata1 add datafile '<filename>' size 2048M;
What I should have done:
alter tablepsace <tablespace_name> add datafile '+DATA1' size 2048M;
Is there any way to move this filesystem datafile into the asm tablespace? In previous Oracle versions, I've taken a tablespace offline, moved a datafile, renamed it, then brought the tablespace back online. Can I do something similar here in this situation?
