Ora 12801 Error Signaled In Parallel Query Server P007
of information into a multitude of tables and functions. 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 ora-12801 error signaled in parallel query server p004 confusing origins, but is described as an error resulting in some form from a 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 tha

The script was executed by user and I can see 1 user in OS but see http://www.dbasupport.com/forums/showthread.php?46331-ora-12801-parallel-query-server 4 oracle users running the program each as p000,p001,p002,p003. can anyone give little input why I can see 4 oracle users. Is that because the queries running in parallel ?? But if it is a script does not it execute one after the other. User got a error later ORA - 12801 error signalled in parallel query server p003. ORA-01652 unable to extend temp segment by 1024 in tablepsace temp. The temp tablespace is 8G. This is happening because of the process running in parallel. where is the problem occuring? is that because of parallel queries. what is ultimate solution.

You (probably) need more TEMP when operating with PQ. If you are not specifying your degree with a hint, you might look at the tables involved. They probably have a degree > 0. To turn PQ off, you can override the default degree with +PARALLEL(table_alias,1). Jeff Hunter marist89@yahoo.com http://marist89.blogspot.com/ "I ple

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 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.
