Patch 9239090 - ORA-04021: timeout occurred while waiting to lock object

Hello Guys,
I need help urgently to comlete an upgrade of ebs 12.1.1 to 12.1.3.
We are upgrading ebs 11i to 12i going live this weekend. We have encountered "ORA-04021: timeout occurred while waiting to lock object" on patch 9239090 with two Workers:
In adctrl:
1 Run AutoPatch R120 AFUTLGRS.pls FAILED
2 Run AutoPatch R120 AFUTLOGS.pls FAILED
sqlplus -s APPS/***** @/u02/applfinp/apps/apps_st/appl/admin/OFPROD/out/p001invok.sql

create or replace package wf_bes_cleanup AUTHID CURRENT_USER as
ERROR at line 1:
ORA-04021: timeout occurred while waiting to lock object
I have done everything everything imaginable but cannot get pass these 2 failed workers.
1) I have checked are there are no locks blocking on any objects:
select s1.username || '@' || s1.machine
|| ' ( SID=' || s1.sid || ' ) is blocking '
|| s2.username || '@' || s2.machine || ' ( SID=' || s2.sid || ' ) ' AS blocking_status
from v$lock l1, v$session s1, v$lock l2, v$session s2
where s1.sid=l1.sid and s2.sid=l2.sid
and l1.BLOCK=1 and l2.request > 0
and l1.id1 = l2.id1
and l2.id2 = l2.id2 ;
2) I also checked and there is space in the database.
3) From adctrl, I have tried restarting the jobs one by one but the worker 1 hangs at and eventually fails on several (12) attempts.
4) The solution on Doc ID 1291064.1 is not the problem:
SQL> select SUPPLEMENTAL_LOG_DATA_MIN, SUPPLEMENTAL_LOG_DATA_PK, SUPPLEMENTAL_LOG_DATA_UI, FORCE_LOGGING
from v$database;
SUPPLEME SUP SUP FOR
NO NO NO NO
5) Manual execution still gave ORA-04021:
sqlplus -s APPS/apps @/u02/applfinp/apps/apps_st/appl/admin/OFPROD/out/p001invok.sql
sqlplus -s APPS/apps @/u02/applfinp/apps/apps_st/appl/admin/OFPROD/out/p002invok.sql
6) The alert log has no related errors
7) I Finally, after over 6 hours of waiting, I could only get the patch to continue after by using adctrl option 8 to skip these two workers.
After proceeding, I have yet hit two more errors and now stuck:
I have hit another error with the same patch:
create or replace package body FND_LOG as

Ora-04021: timeout occured while waiting to lock object.

I have upgraded the DB From 8.1.5 to 8.1.7 then 9.0.2
but while converting to 9i it gave a warning that
"some uncompiled objects were found".
now the DB works fine with every DDL and DML operation but when I edit any precedure or function it hangs for 4 to 5 mins and then show the following error
ora-04021: timeout occured while waiting to lock object.
when I shutdown the DB and restarts it then it allowes me to edit any founction or procedure or package only for one time,then again shows the error when I try to edit second time.
what my be the reason , can any body help me pl.
thankx in advance.

If you have oracle metalink support, then, read Note:169139.1. If not, give me your email id, i will send you the note.

robyav

this is a production database runing in windows platform and there is no backup
what should iWell first of all you should stop using EXP for backups, it's quite unsuitable, and start using RMAN instead. Find out more.
If you have a Metalink account you shoudl read Note:298968.1. But teh headline is there is a bug in 10gR1 which is fixed in 10gR2. This may not help you much. The workaround is to try running the export again later, which may not be any more helpful.

ORA-02049: timeout: distributed transaction waiting for lock

Hi,
My name is Guneet and I'm working on an application running on BEA Weblogic Server 9.2 running on a Red Hat Linux box using Oracle 10g as the database. My problem is that recently our code started getting the following exception while updating a database table.
java.sql.SQLException: [BEA][Oracle JDBC Driver][Oracle]ORA-02049: timeout: distributed transaction waiting for lock
Application Details
* Using Stateless Session EJB
* Only one Business method in this EJB with transaction attribute set to "required"
* This method executes two select queries & one update query
* We are using JDBC to access the database.
* We have configured a Data Source & are using it to get a database connection.
* Weblogic's Oracle Driver is being used.
More details
* The application has been running well since a month.
* Two days ago,the update query failed with the above error.
* At that time, a single client was accessing the system.
* Once this problem occurs, it starts appearing frequently.
* Eventually a request to get a connection from the Data Source times out & the exception copied at the end is thrown
* At this stage the application gets stuck and all requests trying to get a connection end up with this exception.
* Fortunately, Restarting the Weblogic Server gets us out of this problem and transactions resume normally.
Now my questions are
# Why is this error happening & what does it mean?
# It looks like the second exception (unable to get a connection from ds) is an after effect of the first problem (ORA-02049) once it appears for a couple of times. Can somebody validate this?
# Though I don't understand JTA well but I don't think this application needs distributed transactions so, I'm thinking of modifying the driver type to non-XA oracle driver. Any advise/pointers/comments on this front is welcome !!!!!!!!
Thanks

Guneet SahaiHi Guneet. If you want to debug the JTA issue, I suggest opening an official
support case. They will lead you through producing the JTA debug information.
However, I believe you are correct that the transaction you describe is
completely doable with a simple local transaction, so if you were to alter
your pool to use the non-XA driver, it would probably be faster, simpler,
and just work.
Let me know...

OWB9.0.4-- ORA-02049: timeout: distributed transaction waiting for lock

I'm running a simple mapping that copies all columns of data (using a filter on date for just current records) from one table in SQL Server into a staging table on my Oracle DW schema. It's using a dblink with transparent gateway for SQL Server, which works fine from SQL*plus.
The map is in default mode (bulk-failoverto-row) with bulk size and commit frequency = 1000.
The audit details show the first 1000 rows selected on the source, with an error on both the source and target tables:
Target--
ORA-02049: timeout: distributed transaction waiting for lock
Source--
ORA-01002: fetch out of sequence ORA-02063: preceding line from INTERGRATION@JXNSQL01
(INTERGRATION@JXNSQL01 is the dblink name)
Any ideas on how I can clear this up?
Thanks,
Paul

Hi,
After having upgraded to 9.0.4 (from 9.0.3) I'm running into exactly the same problems with some of my mappings. Actually I don't get any rows transferred from the mappings that fail.
Out of 7 mappings, 3 worked just liked before while the 4 others just keep on running until I cancel them and I then see the BUSY/ORA-02049 in the Audit Browser.
When comparing the mappings I see that the 3 that works all use some custom Procedures I have made.
The 4 that doesn't work are all very simple - one of them just loads all the content from a table with two columns in my source to another table with two columns in my target! Two of the other mappings that doesn't work includes some simple CASE-expressions.
Both my source and my target resides in a Oracle 9.2.0.3 database (not the same).
Regards,
Bent Madsen

DatabaseError: ORA-02049: timeout: distributed transaction waiting for lock

Hi all
There is script running in my database 'A' that will select some data from tables in other database through DBLINK and update some tables too. The script which 6 I am running for the past 6 monts succesfully. Yesterday I got error saying that,
DatabaseError: ORA-02049: timeout: distributed transaction waiting for lock
ORA-02063: preceding line from test
I have tested the Link and its active no issues in DBLINk
I understand the objects which I am accessing the table in locked mode,
SQL> select OBJECT_ID,SESSION_ID,PROCESS,LOCKED_MODE from v$locked_object where
SESSION_ID=121;
OBJECT_ID SESSION_ID PROCESS LOCKED_MODE
77391 121 21394 3
i
I killed the session 121 and in v$session status is Killed, but I am getting the same error repeating while running the script. And the session_id is still in locked_mode.
Could please add some light on this?
-Thanks
Antony

Hi,
I have killed the session which caused blocking and the status is KILLED for the past two days. But still the object is in locked mode
SQL> select OBJECT_ID,SESSION_ID,PROCESS,LOCKED_MODE from v$locked_object where
SESSION_ID=121;

How would I resolve this any idea
-Thanks & Cheers

JDAPI Error: ORA-04020: deadlock detected while trying to lock object

I have written a JDAPI program to perform read-only impact analysis and report any problems.
The following error is occurring:
"A deadlock among DDL and parse locks is detected.
This deadlock is usually due to user errors in the design of an application or from issuing a set of concurrent statements which can cause a deadlock.
ORA-04020: deadlock detected while trying to lock object /NSPC6/CHECK_FOR_FORM_CHANGE"
The error refers to a procedure in a PL/SQL library.
In one case the error occurred after my final "end of processing" message, which is followed only by a call to "Jdapi.shutdown()".
Any ideas?
Thanks,
Neville Sweet.

Hi Steve,
I recommend that you contact Oracle RDBMS support directly.Our

ORA-04020: deadlock detected while trying to lock object

I was wondering if somebody could give me some advise on how to fix this problem.
I have a table that I use for my full text search functionality in my web app.
In this table I have an id and 1 clob column indexed using the intermedia.
I have a stored procedure that does the populating and reindexing of this table and this should be run under dbms_jobs.
What this procedure basically does is it concatenates the values of different textual columns in my schema and I stick it in in this clob column using the dbms_lob.writeappend, I have a loop that does this, and at the very end of the stored procedure I call a reindex of this clob column. This error occurs when it hits this reindex line. If I run the reindex outside of the stored procedure then it works fine. I need to put this functionality in 1 stored procedure so I could easily run it periodically using the dbms_jobs.
This is the skeleton of my stored procedure: (Oracle version is 8.1.7.0.0.)
procedure rebuild_my_intermedia_column is
--cursor declaration here
cursor outercursorvar is select ...
cursor innercursorvar is select ...
--variable declaration here
vstr varchar2(32727);
vclob clob;
vlen1 binary_integer;
vlen2 binary_integer;
begin
for v1 in outercursorvar loop
vstr := ' ';
vlen1 := 1;
select intermedia_column into vclob from intermedia_table where pkid = v1.id FOR UPDATE;
for v2 in innercursorvar loop
if v2.textualcolumn is not null then
vlen2 := length(v2.textualcolumn);
if vlen1 + vlen2 > 32727 then
dbms_lob.writeappend(vclob, vlen1, vstr);
vstr := ' ';
vlen1 := 1;
end if;
vstr := vstr | | v2.textualcolumn;
vlen1 := vlen1 + vlen2;
end if;
...more columns here
end loop;
if vlen1 > 1 then
dbms_lob.writeappend(vclob, vlen1, vstr);
end if;
commit;
end loop;
--This is where the dealock error comes!.
execute immediate 'alter index clobcolindexname rebuild parameters(''SYNC'')';
end;
I would appreciate your help on this.

FYI. The alter index interface for SYNC and OPTIMIZE is no longer supported in 9i. We have discouraged the use of alter index for SYNC and OPTIMIZE since the PL/SQL
interface for these was added in 8.1.6. Failures during sync or optimize can invalidate the index when using the alter index interface, forcing a complete index
rebuild. The PL/SQL API does not carry this risk.
For re-indexing we are recommending to use CTX_DDL.SYNC_INDEX called from a DBMS_JOB. Please take a look at the ctx_schedule utility at: http://technet.oracle.com/sample_code/products/text/content.htm

ORA-04021:timeout...

Hi guys,
I have a problem: when I try to replace or delete a package I recive
an error message ORA-04021: timeout occurred while waiting to lock object XXX
Of course it's becouse this package is used by another session.
In v$access table I've found out whitch session it is, but I don't
know how to kill or stop this session to allowed replacing of package.
I killed the session and its status is marked as killed but the
package is still used.
Pls help me it's very important. Any solution how to compile this
package is welcomed. Restart of database doesn't help, I tried :-(
Thanx a lot.

Most likely, the problem is that someone else in some other session is calling your procedure, which prevents you from locking it in order to run DDL against it. If this is a busy system, you'll likely have to wait for a downtime window in order to run your DDL. If this is not a busy system, you may be able to just retry the operation.

ORA-00060: deadlock detected while waiting for resource CLOSE cursor

Hi,
I am a new member of this forum. I am working with a problem we got a few weeks ago. It is from a Pro C batch executable running on 10 threads dealing with >800 data accessed from multiple tables. The error as reported came from a package.function call.
This is the error I encountered:
process_item~G****, D***~-60~ORA-00060: deadlock detected while waiting for resource~PACKAGE ERROR = CLOSE cursor C_***** in package R***.I*** 7641
The cursor is a simple SELECT cursor without Table or Record locking.
My questions are:
*Upon the occurrence of this error, is the execution already at the CLOSE cursor line or did the error occurred between the OPEN cursor and the CLOSE cursor? There are several lines of code in between OPEN and CLOSE:
- one that calls for a package.function that simply stores parameter values to a variable
- another one which fetches the cursor. The group that holds the cursor values is only used by a single function in the package
*Is it possible for this CLOSE cursor to cause a deadlock? What could have caused this?
*From what I know, Oracle deals with deadlocks by aborting the deadlocking process while others continue, but this deadlock caused our program to hang. How is this possible? Could the root cause of the deadlock be from our threading program? This is a rare occurrence and happened only twice this year.
Thanks,
Raf

RafSELECT (without FOR UPDATE) statements are never involved in ORA-00060.
only DML statements throw ORA-00060 error

Ora-00060 dedlock detected while waiting for resource

hi All,
version 6i.
i have a button save in my form when users makes any changes in the existing records and then press that save button they get an error frm-4059 unable to update record
when i see the actual error by pressing shift+f1 i found ora-00060 deadlock detected while waiting for session.
can any one know why this error occurred and how can i fix it.
thnx.

hi
check error log and what trace file is saying?
To resolve the issue, make sure that rows in tables are always locked in the same order.
For example,
in the case of a master-detail relationship, you might decide to always lock a row in the
master table before locking a row in the detail table.

Database error"ORA-00060: deadlock detected while waiting for resource"

Hi All,
I got dump as
Database error text........: "ORA-00060: deadlock detected while waiting for
resource"
Internal call code.........: "[RSQL/RDUP/NRIV ]"
Please check the entries in the system log (Transaction SM21).
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_OPEN_SQL_DB', was not caught
in
procedure "READ_NRIV" "(FORM)", nor was it propagated by a RAISING clause.
Can u ppl tell me how to get correct this?

Hi Bala,
Same type of dump we got when we trigger the DTP which in process chain to load data from DSO to Info cube. And the load had processed with 225 data package and at 164th data package we got this error and except 164th data package all data package processed successfully
And the request was red. So we had done processed manually by clicking the icon. So all its been green and successfully loaded.
So when you do process manual the particular data package which got failed will be process successfully

Hi Team,
My database version is 11.1.0.7.0. I am loading the data using sqlldr.
