Oracle error-parallel query

Hi Experts,
While i'm running a parallel query through a procedure...
its throwing the below error.....
when others Error ORA-12801: error signaled in parallel query server P006
ORA-01114: IO error writing block to file (block # )
ORA-01114: IO error writing block to file 1025 (block # 2790848)
ORA-27063: number of byte with query
Can you people suggest me?
Thanks in advance!!!

You probably meant 11.2.0.3 instead of 11.2.3.0?
Did you (or your DBA) check the alert log?
What happens if you remove your WHEN OTHERS and rerun the code?
Do you get any additional information?

Error on Parallel Query

Hi,
My application throws the following error when Iam processing a parallel query on my database. Can any one help me to resolve this.
ERROR at line 1:

HI,
Thanks for the article. I read the article but my problem is getting addressed. I have enough disk space and rollback segments.
7 rollback segments (1 default 200 MB + 6 created for my executing wtih 1GB each ). All of them are auto extended 10M per block.
Apart from this I have a free space for 25 GB in the drive left out. Inspite of all of these. I am getting this error.
I am not able to understand the "DreKrgm" part.
Can you throw some light on this part.

ORA-12801: error signaled in parallel query server P000

Hello All,
Week before one of the APPLY process ABORTED with following error:
ORA-12801: error signaled in parallel query server P000
ORA-04031: unable to allocate 104 bytes of shared memory ("streams pool","unknown object","apply shared t","knalfGetTxn:lcr")

It seems that you are using Oracle database and not Berkeley Database.
To fix ORA-04031 errors on streams pool, you need to increase streams pool size with
alter system set streams_pool_size=<the right value>;See recommandations in http://download.oracle.com/docs/cd/B19306_01/server.102/b14229/strms_mprep.htm#i1006278

SQL Error: ORA-12801: error signaled in parallel query server P007

Hi all
I am getting the following error when doing aggregation for a cube
SQL Error: ORA-12801: error signaled in parallel query server P007.Job is showing as finished but no aggregation is hapenning.
regards
KK

for ORA- 20000
check the note below it shows you have insufficient authorizations.
Reason and Prerequisites
You are using BW 7.00 with Support Package 07 or higher.
The BW module for the update statistics has been adjusted to SAPDBA or BRConnect (with regard to the heuristic, which is when, how and which statistics are created). To ensure that all table changes are taken into account, the relevant information must be flushed from the Oracle memory before the update statistics is carried out. For this purpose, the SAPCONN role (higher than ORA 10.2) or SAP SAP<sid> oder SAPR3 (ORA 10.1) requires additional authorizations that were not assigned up to now.
 Note 963760 - 'ORA-20000: Insufficient privileges' for creating statistics
For Error -for SQL Error: ORA-01418: specified index does not exist
check note below-
Note 337830 - BW: ORA-1418 in system log
It seems that Index no longer exist which you are trying to delete.The 900 index, which exists on the F table only if the E table is partitioned, is deleted twice and on the second attempt it no longer exists.

Note 1003360 - BW fact tables: Deleting index from process chain terminates
If it relates your error it requires corrections for SP-12.
Hope it Helps

Error in Parallel query server

I got the following error while import data.You are doing import with datapump or imp ?
If so, look at the import log where ORA-01452 is mentioned, you should find the name of the table there for which ORA-01452 is raised.
Hi All,
ORA-01452: cannot CREATE UNIQUE INDEX; duplicate keys foundYou are trying to create unique index on the column where duplicate values exists.
By the definition of unique index, that would be impossibe.
So, either remove 'unique' from the create index syntax , or make sure there are no duplicate values in the coulumn on which you are creating unique index.
Could you resolve it?No, that should be your responsibility.

Urgent, ORA-12801: error signaled in parallel query server P000

Hi Guys,
I am using Oracle 9i Enterprise Edition Release 9.2.0.1.0 with Windows 2000 Server.
I have just upgrade my database from 8i to 9i. I am facing this problem in a lot of queries in my application after upgrade. I tried to searched out but unable to find the reason yet.
Is there any parameter which i should /should not use? Or need to change any parameter.

Well, the error stack should be displayed along with the 12801 error.
If not, look the comment for the error I posted above: use event 10397 to display the actual error.ALTER SESSION SET EVENTS '10397 trace name context forever, level 1'; and if the error raises, then you'll get the source message, not the PQ message.
See note 21281.1 on Metalink.

"ORA-12801: error signalled in parallel query server"

A client of ours is using our reporting tool, Impromptu 6, to report from an Oracle 8.1.6 database connecting with Net8. He has built a simple report which displays a single item from a single table but it fails with:-
Query Server Error
"ORA-12801: error signalled in parallel query server"
Error number -9:
DMS-E-GENERAL, A general exception has occurred during operation 'asynchronous open'.
According to Oracle documentation, there should be an accompanying error message with the ORA-12801 which gives more information.
The last few lines of the DMAUDFIL show:-
OCI OEXEC LINE 5219:orsgbl.C
OCI OEXEC LINE 5219:orsgbl.C
CHECK_CODE2 -12801 LINE 5249:orsgbl.C
OCI OERHMS -12801,ORA-12801: error signaled in parallel query server
LINE 858:orsmisc.C
The DMAPIFIL shows no error.
The query being sent to the database is:-
select T1."PRD_LVL_PARENT" "c1"
from "JDAOPRD"."PRDMSTEE" T1
where PRD_LVL_PARENT is defined as NUMBER(12)
If they paste the above into SQL*Plus, it works fine.
Reporting any other items from the database do not give this error.
If they use the Oracle ODBC driver, they don't get the problem but it runs a lot slower.

As your ORA-12801 is followed by a ORA-0600 this should be a database bug. First of all I'd bring the database on the last patchlevel (10.2.0.5), and if the error persists you can use the ORA-600/ORA-7445 Troubleshooter (Metalink Note 153788.1). If this doesn't help either you should log a SR with oracle support (you need a support contract to do all those steps).
Also I don't think forms 5 is certified against a 10gR2 database, so this might cause your trouble. For 6i you should use the latest patchset.
If you don't have a valid support contract you might have a chance in putting your query in a database procedure.
cheers

ORA-12801 error signalled in parallel query with ORA-00018 max # session

Hello,
I've just run dbca to create a new database. On completion I received the following:
ORA-12801 error was signalled in parallel query server
ORA-00018 maximum number of sessions exceeded
ORA-06512 at sys_utl_recomp line 760

The processes are set at 100, sessions is set at 115?
Can you tell how to address this error and resolve the problem? I'm thinking that I should rerun sys_utl_recomp

If the data never changes, there would be no reason to gather statistics.
If the data changes, there may or may not be a reason to gather statistics. There is some risk to gathering statistics because that can cause query plans to change and you could find that a query that was working fine yesterday is running very slowly today. Failing to gather statistics, though, can have the same effect-- if a histogram on a column indicates that the maximum value of a date field is December 1, 2006 because you haven't updated statistics in a few days, the CBO may conclude that a query this column with a value of December 4 would return very few row, rather than the many rows that are really there, causing Oracle to use a different query plan. Oracle tends to believe that the latter risk is more of a concern than the former and in 10g regularly and automatically gathers statistics unless you susped that job. Some DBAs disagree with Oracle and prefer less frequent, more controlled statistics gathering.
If you GATHER AUTO, assuming your tables are set to MONITORING, Oracle gathers statistics on every table that has had more than some cutoff percentage of rows changed since statistics were last gathered. This cutoff is generally pretty reasonable, though ideally you'd probably want to gather statistics more frequently on smaller tables (adding 30 new rows to a 100 row table is probably more significant from a query plan perspective than adding 3 million rows to a 10 million row table) and less frequently on larger tables, more frequently on tables that have volatile data distributions (i.e. our DATE table) and less frequently on tables whose data distribution is relatively constant.

A week before we stopped oracle using "Shutdown abort" command. But two days before we stopped using "shutdown immediate", it went fine and system up and run fine.
But today it stopped with this error message.
Operating system : SOlaris 10
I changed the parameter parameter fast_start_parallel_rollback to HIGH from LOW, but no use
SQL> ALTER SYSTEM SET FAST_START_PARALLEL_ROLLBACK=HIGH SCOPE=BOTH;
System altered.
SQL> show parameter fast_start_parallel_rollback

Usually The dead transaction will be rolled back after raising the Priority from LOW to HIGH. But this time its not rolled back. still etting the same error.
Your answers will help to stop the oracle getting down in the LIVE production server. please share your experience guys.

Hi,
I wrote the code to uploada to a flat file (.txt format) by using UTL_FILE package in PLSQL. In that code I redirected errors to a error file.
It is uploading the correct data to the file, and also generating a error file with the below error message.
Upload Type: cat Error Code: -12801 System Message: 10/21/2008 13:19:39 Oracle Message: ORA-12801: error signaled in parallel query server P026, ins.
here the word 'cat' is part of my file name passing through exception part in PLSQL code.
Below is exception part of my PLSQL program:
EXCEPTION
WHEN VALUE_ERROR
THEN
p_write_to_upload_log ('cat', TO_CHAR (SQLCODE), 'Value error reading Retail upload', SQLERRM);
WHEN UTL_FILE.invalid_filehandle
THEN
p_write_to_upload_log ('cat', TO_CHAR (SQLCODE), 'Write error on upload file', SQLERRM);
WHEN UTL_FILE.invalid_operation
THEN
p_write_to_upload_log ('cat', TO_CHAR (SQLCODE), 'Upload file is not open', SQLERRM);
WHEN UTL_FILE.read_error
THEN
p_write_to_upload_log ('cat', TO_CHAR (SQLCODE), 'OS error during file read', SQLERRM);
WHEN OTHERS
THEN
p_write_to_upload_log ('cat', TO_CHAR (SQLCODE), TO_CHAR (SYSDATE, 'MM/DD/RRRR HH24:MI:SS'), SQLERRM);
END p_cat_upload;
Please let me know if you need any more information on this.
Appriciate your help in resolving this error message.
Thanks and Regards

Do you have cursor_sharing set to force or similar? if so then you may be hitting bug Bug 5863277. Please confirm with Oracle support.

During Table Import got error ORA-12805: parallel query server died unexpectedly

Hi,
I tried to import a single table of size 51 GB which normally imported in 5 hours but last time I got following error after 1.5 hours
ORA-31693: Table data object "SCHEMA"."TABLE_NAME" failed to load/unload and is being skipped due to error:
ORA-12805: parallel query server died unexpectedly.
From the "Alert log" file I found the error is
ORA-00603: ORACLE server session terminated by fatal error
ORA-24557: error 1114 encountered while handling error 1114; exiting server process
ORA-01114: IO error writing block to file 622 (block # 373725)
ORA-27063: number of bytes read/written is incorrect
IBM AIX RISC System/6000 Error: 28: No space left on device
Additional information: -1
Additional information: 253952
I checked all the table spaces have more then 100GB free space. No idea why this happened.
Some mount points of the machine is 100% in used where the table spaces created but in table spaces auto extend is off on every data file and each data file have free space.
Anyone have idea how to resolve this issue.

Hi,
Which filesystem is file 622 in - it's quite a lrge numbered file - is it a tempfile or do you really have that many datafiles?
Regards,
Harry
