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 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 that as your number of parallel query

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.

The script was executed by user and I can see 1 user in OS but see 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 error signaled in 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. I appriciate your help Reply With Quote 02-04-2005,10:55 AM #2 marist89 View Profile View Forum Posts Visit Homepage Super-Genius Join Date Nov 2000 Location greenwich.ct.us Posts 9,092 Yup, its a parallel query issue. 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).

I see the first table degree value 1 and other table degree as 2 in user_tables. +parallel hint is need if the table is in parallel right ? I am not understanding why the query is running in parallel when there is no parallel option is true or valu is 0.

in parallel query server) [message #75066] Mon, 18 June 2001 23:14 Rajee Messages: 17Registered: June 2001 Junior Member Hi, Actually we want to upgrade an oracle database in 7.3.4 to oracle 8.1.7. The database is working perfect in oracle 7.3.4 and oracle 8.1.7 if we use export/import options. But, if we use migration assistant (GUI-in WinNT) we are getting ora-12801 error followed by ora-00942 (table or view does not exist). This problem is coming when we try to execute a particular query, that too from the front end - VB6.0. The same query is running perfectly if we run it in the backend. Can anyone help us out in this.
