Server Administration :: ORA-01578 - ORACLE Data Block Corrupted
Sep 4, 2012
I am having 3 oracle database instances running on 3 seperate Linux Node(RHEL Node).
Instance -1 named - DS
Instance -2 named - MIS
Instance -3 named - OAS
Among of these 3 nodes, we are facing Block Corruption issues with sysaux tablespace.Error in Instance name DS is
Errors in file /u01/home/dba/oracle/diag/rdbms/ds4db/DS/trace/DS_j000_655388.trc (incident=300847):
ORA-01578: ORACLE data block corrupted (file # 2, block # 38428)
ORA-01110: data file 2: '/DSdb1/dssysaux.dbf'
ORA-26040: Data block was loaded using the NOLOGGING option
GATHER_STATS_JOB encountered errors. Check the trace file.
[code]....
for this I googled and found some solution as oracle doc [430230.1] related to sysaux couruption.After this again we are facing the same issue in sysaux tablespace.
I have an application that writes blobs via pro*c. It is running at several sites without errors for a few years now. One of the newer sites has started reporting "ora-01578 ORACLE data block corrupted".
I've tried using rman backup validate - it does not report any errors.
I've tried using rman restore and recover to correct the problem.
I've tried deleting the file with the corrupt block and using rman restore and recover to recreate it.
In any of the above cases, I do not see any errors being encountered, and when I restart the application, it works for a while and then starts reporting "ora-01578 ORACLE data block corrupted".
I've had the client do a physical check of the disk and it indicated the media was okay.
We've failed over to the standby system, so I have a wee bit of breathing room - but I'm going to be away for 4 days and will have to get back on this when I get back. I'm a little puzzled that I can fix it for a short while and then it breaks again.
we are running oracle 9iR2 ( 9.2.0.1.0) on windows server 2003 R2 and facing ORA-01578: ORACLE data block corrupted (file # 17, block # 312316)
SQL> select * from payrol.slip; select * from payrol.slip * ERROR at line 1: ORA-01578: ORACLE data block corrupted (file # 17, block # 312316) ORA-01110: data file 17: 'E:ORACLEORADATAMTMASYSMTM.ORA' ORA-26040: Data block was loaded using the NOLOGGING option
1) SELECT name FROM v$datafile WHERE file#=17; output E:ORACLEORADATAMTMASYSMTM.ORA
2) SELECT block_size FROM dba_tablespaces WHERE tablespace_name = (SELECT tablespace_name FROM dba_data_files WHERE file_id=17); output 8192
3) SELECT tablespace_name, segment_type, owner, segment_name FROM dba_extents WHERE file_id = &AFN and &BL between block_id AND block_id + blocks - 1;
We are facing block corruption error and it's refer to system datafile (SYSTEM01.DBF).Below is the script through it, we can come to know about the extent.
select segment_name, segment_type from dba_extents where file_id=1 and 134144 between block_id and block_id+blocks-1;
select owner,index_name,index_type, table_name from dba_indexes where index_name='I_CDEF3';
How to resolve the problem as it is related to system datafile? We tried to drop the index but system is not allowing to do.
ORA-00701 - object necessary for warmstarting database cannot be altered.
SQL> select OWNER,TABLE_NAME from dba_tables where TABLE_NAME='Viep_Porteur_Etudiant'; OWNER TABLE_NAME ------------------------------ ------------------------------ IEP_PESSAC Viep_Porteur_Etudiant
But this tables doesn't exist then I can't drop this table:
SQL> desc IEP_PESSAC.Viep_Porteur_Etudiant; ERROR: ORA-04043: objet IEP_PESSAC.Viep_Porteur_Etudiant inexistant SQL> drop table IEP_PESSAC.Viep_Porteur_Etudiant; drop table IEP_PESSAC.Viep_Porteur_Etudiant * ERREUR à la ligne 1 : ORA-00942: Table ou vue inexistante
How can I clean dba_table? I suppose that that's happened because the user tablespace was full when he tried to create this table...
I am using oracle 10g R2. Some how control file is corrupted and database is not open. and there is no backup of control file. Now i need to open the database without recreating the database.
1) What is PHYSICAL/LOGICAL Corruption. 2) How it occurs. 3) Will RMAN works on both the types of corruption or only Physical (My senior told it works on both).
I am the only DBA in my company and Oracle just crashed on me. The data is corrupted as well as the data on my backup! Is there ANY way I can get the information back?
ORA-00607: Internal error occurred while making a change to a data block ORA-00600: internal error code, arguments: [4194], [89], [83], [], [], [], [], []
I am using oracle 10g with sga_max_size =4GB and db block size 16k. Now i am creating a tablespace with block size 32 kb , whats value i select for the parameter db_32k_cache_size.
Is there any standard way to calculate the value of this parameter.
Is there any way I can calculate percentage of space used in a block.Eg if a table size is 100 blocks,How Can I check the percentage of used space in block.
One of our developers team member had created a Anonymous block program to do something in the Database, and he forgotten and terminated the session without confirming the program's status, whether it was fully ran or not.
Is there any way to check out the status of this, which happened yesterday?
I am in charge of several instances located on a Linux server CentOS, virtualized on a ESX 3.5 environment.
From time to time (every 4 to 5 days), I have some errors in the alert.log. Last occurence was last night :
Corrupt block relative dba: 0x01004e12 (file 4, block 19986) Fractured block found during buffer read Data in bad block: type: 6 format: 2 rdba: 0x01004e12 last change scn: 0x0000.131aaa5b seq: 0x2 flg: 0x04 [Code] ........
We are doing user manual backup (with BEGIN/END BACKUP) every night at 8PM, ending at 9PM approx. Then, fractured blocks never occur during backups. At 1AM, the maintenance window is opening, thus explaining the GATHER_STATS_JOB job.
When I check corruption on early morning, I am always unable to reproduce the problem. DBV is OK without issues. We never had a problem with the data itself, whatever it is a table or an index in the reported failed block.
I would like to know what could cause these logical corruption, and how to stop them ?
I am not able to get the relevant segment from the above information
SQL> select segment_name, segment_type, owner 2 from dba_extents 3 where file_id = 4 4 and 756652 between block_id 5 and block_id + blocks -1;

Recently we have a weird thing happens in our Oracle Queries to the views return "ORA-00942: table or view does not exist" unless there are a where clause
select * from VIEW1 failed select * from VIEW1 where 1 = 1 works
I have read almost all docs about distributed transaction on tahihi.oracle.com website,But I can find a statment about this:
Can Oracle always guarrantee the data consistent in a distributed transaction?
For example,there is a distributed transaction on node a,node b and nod c.node b and node c informed node a they were prepared,so node a committed,and inform node b and node c commit.then node b committed and feedback,but network on node c broken at this point,So node a can't not get feedback from node c,but node a and node b has been committed, so what will Oracle do in this condition?
If node c rollback the data on local node, consistent in this distributed transaction was failed ,yes?
i written this code i m facing ORA-04030: out of process memory when trying to allocate 16408 bytes error
/* Formatted on 2011/11/26 11:52 (Formatter Plus v4.8. */ DECLARE row_id varchar2(50); v_batch_id temp.batch_id%TYPE; v_slab_id temp.slab_id%TYPE; flag NUMBER (2); num varchar2(50) := &row_id;
My understanding of DB_FILE_MULTIBLOCK_READ_COUNT parameter is that it affects only Full Table Scans and Fast Full Index Scans - all other disk retrieval is single block.If so, then maybe I'm reading this trace incorrectly:
select /*+ first_rows */ pk from test_join_tgt where pk >= 0 and rownum > 1
i am continuously inserting data to oracle database after some time like 2 hours oracle disconnects,it creates erros like
ERROR: ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist Process ID: 0 Session ID: 0 Serial number: 0
after restarting the database with shutdown immediate ans startup if i start inserting records it will show erros like
ORA-01653: unable to extend table SYSTEM.GLT_PROT_TRAFFIC_SUM_VOIP by 8192 in tablespace GLCOMM
but i have created the Tablespace with BigFile Auto Extend and max size unlimited, i am having 400GB disk space created Redo logs with 15gb,i have tried serveral times reinstalling the oracle but problem is not solved.
same problem is happenging with small datafiles also,
operating system: windows server 2008 R2 standard oracle server : 11g oracle client : 64 bit
i have multi data block filed. and checkbox field which based on control block...My task is when i check checkbox only one field should enabled and my mouse goes to that field
