I keep getting an ora-04020: deadlock detected while trying to lock object XDB. SDNRB..The statement I'm trying to issue is:
REVOKE execute on abc."descript_T" FROM PUBLIC;
I am not able to find a solution for this besides the fact of trying the operation again at a later time.I did, but get the same error every single time.
I am getting "ORA-00060: deadlock detected while waiting for resource" while deleting a datafile.
when i checked in dba_data_files and V$datafile the ONLINE_STATUS/STATUS is in RECOVER mode.
I do not need this datafile so i tried to drop using the following command ..
ALTER TABLESPACE DATAP_LARGE DROP DATAFILE 'D:\ORACLE\ORADATA\DATAP\DATAP_LARGE_12.DBF';
I checked the Trace file geenrated for the deadlock, the Session which is in question is the session where i ran the command (SQLPLUS).
i am getting a below error whenever executing the below select query. some times it will show dead lock detected while waiting for resource and terminated...some times it executes and gives result..but all the time it writes an alert to alert log

we know we can see lock mode held in session can be analysed using LM column in v$lock.But i confused in seeing LM column it all shows in numbers from 0 to 6.

I am working on 11g and AIX...We got deadlock recently and we need to investigate why it happen and resolution, so it will not happen in future. When we saw deadlock trace file ,it shows 2 sqls queries on different tables..and lock is exclusive lock.
----- Information for the OTHER waiting sessions -----
SELECT 1 FROM HOS_DTL WHERE ( HOS_LCN_DTL.HOS_LCN_DTL_ID = :1 ) FOR UPDATE WAIT 180
and

But these two tables not related at all 'HOS_DTL' and 'EI_INV' . Can deadlock happen if sqls queries fired on those table are not related at all and deadlock trace file can show those two sqls ..?

1) Trigger of version 1 did not report any error during compilation, but during DML execution, hangs for sometime and gives the above error.
2) Whether direct assignment of Objects of greater size is possible inside triggers built on object Tables?
3) Suppose an object contain multiple attributes (say more than 20), then how to assign them inside a trigger?
I have a problem with executing oracleCommand.ExecuteReader() method. Whatever I try it always returns null and it won't create OracleData reader object. I'm using ODAC 1120320_x64 for .net 4.0 and timesten112241.win64. Don't sure what to do. Debugger is showing strange thing in OracleConnection object : ConnectionState = Closed, but output of ttStatus shows connection to TimesTen data store and ExecuteNonQuery() command works just fine with or without (in or out) parameters. But when I try to execute some query with multile output such as select *, I can't get any result.
I also have a strange problem with connection.Open() When I execute Open() i throws AccessViolationException that can be handled with [Handle ProcessCorruptedStateExceptions] attribute, but connection is established after that and my application works fine until I try to instance OracleDataReader object.
Here is the code:
OracleCommand select = null;
OracleDataReader reader = null;
select = new OracleCommand(selectStmt, connection);
select.CommandType = CommandType.Text;
try
{
reader = select.ExecuteReader(); // this line throws NullReferenceException

I am facing Deadlock issue in my transaction when record is been deleted in the same table in parallel from a PLSQL package. The package is been called from the Java code.The example and the table structure is given below.
Col1 of tab1 is foreign key to col1 of tab2.
Commit will not be done until all the below dml scripts are executed in both environment.
1st session:
Delete from tab1 where col1=1001;
Delete from tab2 where col1=2001;
Result: Deletion successful
2nd session:
Delete from tab1 where col1=1002;
Delete from tab2 where col1=2002;
Result: Deletion successful
1st session:

Delete from tab2 where col1=2003;
Result: Deletion successful
2nd session:
Delete from tab1 where col1=1004;
Delete from tab2 where col1=2004;
Result: Query is executing for a longer time.
1st session:
Delete from tab1 where col1=1003;

So whats can cause this, I can see that TX locks are mostly from JDBC connection from Application server .
In my current project, I am handling an Oracle database with version 10.2.0.3. I analyzed the AWR report for the past month abd saw the following wait events consistently:
CPU time - 45.6% (% Total Call Time)
db file sequential read - 30.6% (% Total Call Time)
enq: TX - row lock contention - 18.8 % (% Total Call Time)
I have uploaded the report for your reference.What should be my approach to troubleshoot this?

how one can lock a particular row in a table.for example i have a employee table in which 50 records. now i want to lock only 10 records of the employee table.
View 8 Replies View RelatedI have a transaction table with some custom properties and two status columns. There are 2 different applications(.Net and Pl/SQL Procedure) using the table. Both the process run parallel and fetch records one by one, perform some calculation and update the status column.
-.Net updates - Extraction_status
-Pl/SQL updates - Ingestion_status
There are likely more chances that both applications will fetch the sane record and try to update the same row. This will cause a lock. Can i use row level lock before update by each application? Or is there any other methods/process in which this can be handled. ?
begin
for i in 1..10000 loop
update table1
set col1= col1+1
where type =1;
commit;
end loop;
end;
My question is, if a strored procedure contains the script above and the said procedure will be invoked by two or more sessions at the same time. Does it mean that the 1st session will lock the related rows and other sessions will have to wait for loop in session one to finish?
i have application where user logs and perform manipulation operation such as insert and update on database table.some time its possible that same user login twice, i just want to hold one session until and unless dml operation perform by another session gets complete.how to accomplish this in database level .
