/ Resources / ORA-12801: error signaled in parallel query server ORA-12801 One of the greatest achievements of Oracle database software is its ability to process massive sums of information into a multitude of tables and functions. ora-12801 ora-01555 The downside is that in any system, dealing with huge amounts of data can naturally carry some headaches and frustration along the way. The ORA-12801 would most easily fall into this category, an Oracle error emanating most often in response to errors when processing large jobs. The Problem The ORA-12801 is an Oracle error that has some confusing origins, but is described as an error resulting in some form from a ora-12801 ora-01652 parallel query server. The error frequently accompanies another error, often the ORA-01652 (which concerns an inability to extend the temp segment in a tablespace). The ORA-12801 is essentially a general error, a sort of catchall for parallel query issues. At this juncture, some of you may be wondering yourselves, “What is a parallel query?” First showing up in later versions of Oracle7, a parallel query option lets multiple processes request and receive data and perform operations at the same time. As you would imagine, this can greatly enhance the speed of the system. To achieve this kind of efficiency, there are several conditions for the parallel query that require attention. So what are those conditions and how do they pertain to resolving an ORA-12801 error? The Solution An absolutely crucial element in successful parallel query operation is the appropriate use of query slaves. If too few or too many are put to use, the system will receive little advantage from their presence. Generally, a good rule to follow is duplicate the number of disks or computers that the operation is used across, and set that as your number of parallel query slaves. Additionally, your tables should account for the parallel query. Run a full table scan to assess the timing of va

Jun 11, 2012 9:42 PM Hi All, Please suggest me appropriate resolution for this below error Select statement : select * from v_putaway where lot_no=91245 and flag_selected=0 Error Faced : ORA-12801: error signaled in parallel query server P081 https://www.tekstream.com/resources/ora-12801-error-signaled-in-parallel-server/ ORA-01722: invalid number Oracle : 11.2.0.3 OS : RHEL 5.4 Thanks I have the same question Show 0 Likes(0) 44329Views Tags: none (add) ora-12801Content tagged with ora-12801 This content has been marked as final.

Re: ORA-12801: error signaled in parallel query server P081 sybrand_b Jun 11, 2012 9:57 PM (in response to 735967) lot_no is a varchar2 column and Oracle translates your query to select * from v_putaway where to_number(lot_no)=91245 and https://community.oracle.com/thread/2402635 flag_selected=0 It fails as you have data problems. Solution: cleans your data, and after cleansing correct the datatype. ------------- Sybrand Bakker Senior Oracle DBA Like Show 0 Likes(0) Actions 2.

Re: ORA-12801: error signaled in parallel query server P081 735967 Jun 11, 2012 10:18 PM (in response to sb92075) hi sb92075, Similar table with similar data under test environment works fine and returns the records. Same thing doesnot works in production after normal import of the schema... So data is similar on both servers, and the datatype is not changed nor the data is cleaned up on test server Please suggest for workaround with similar data and without changing datatype as it has certain dependencies with application Thanks Like Show 0 Likes(0) Actions 5.

Please correct me if https://www.techonthenet.com/oracle/errors/ora01427.php I do not follow the etiquette of posing questions here. I am struggling with an issue which I am unable to root cause. There is a procedure in error signaled my database (Version 11g) which is invoked by a UNIX shell script. This shell script is invoked by TIDAL job when the dependencies are fulfilled. While executing the shell script I get the following error.ERROR at line 1:ORA-12801: error signaled in parallel query server P010, instanceg4u2115c:SCDEP2 (2)ORA-08103: object no longer existsORA-06512: at "IPD.SUM_STADS_I_U_RESELLER_SALES", line 170ORA-06512: at line error signaled in 1Interestingly the job has been failing alternatively. It fails on Say 24 June and is successful on 25 June. Attached is a snapshot of execution history. I have an extensive log file for each run but I don't want to clog the space at the outset. Please let me know what could be root cause and what more information I can dig in to help identify the problem here. Note : There are only 2 instances (Between 10 June and 29 June) when we have seen ORA-12801:.Other than that the error seen is ORA-08103: (Object no longer exists)Jun 24 14:53 sum_stads_sql.12130.log - FailedJun 25 13:47 sum_stads_sql.22092.log - SuccessfulJun 26 14:49 sum_stads_sql.26527.log - FailedJun 27 12:25 sum_stads_sql.10669.log - SuccessfulThanks MuchRicha burleson View Member Profile Jun 29 2014, 10:19 PM Post #2 Advanced Member Group: Members Posts: 13,227 Joined: 26-January 04 Member No.: 13 Hi Richa and welcome to he forum!>> ORA-12801Here are my notes on the ORA-12801 error:http://www.dba-oracle.com/t_ora_12801_parallel_query.htm*******************************************************>> ORA-08103Looks like a bug:http://www.dba-oracle.com/t_ora_08103_obje...nger_exists.htm*******************************************************>> Interestingly the job has

Description When you encounter an ORA-01427 error, the following error message will appear: ORA-01427: single-row subquery returns more than one row Cause You tried to execute a SQL statement that contained a SQL subquery that returns more than one row. Resolution The option(s) to resolve this Oracle error are: Option #1 Rewrite your query so that the subquery only returns one row. Option #2 Change your query to use one of the following with your subquery results: ANY ALL IN NOT IN For example, if you tried to execute the following SQL statement: SELECT * FROM orders WHERE supplier_id = (SELECT supplier_id FROM suppliers WHERE supplier_name = 'IBM'); And there was more than one record in the suppliers table with the supplier_name of IBM, you would receive the following message: The most common way to correct this SQL statement is to use the IN condition as follows: SELECT * FROM orders WHERE supplier_id IN (SELECT supplier_id FROM suppliers WHERE supplier_name = 'IBM'); Share this page: Advertisement Back to top Home | About Us | Contact Us | Testimonials | Donate While using this site, you agree to have read and accepted our Terms of Service and Privacy Policy.
