software is its ability to process massive sums 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. ora-12801 error signaled in parallel query server p006 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 presen

AND papfa.person_id = DECODE(haaif.attribute3,NULL,papfss.person_id,TO_NUMBER(haaif.attribute3)) What could be the reason? Thanks in Adv.

However: how come the same SQL executes fine without PARALLEL hint, as the original poster indicates (if this is actualy true)? It smells more as a bug to me, if what original poster states is true.... Jurij Modic ASCII a stupid question, get a stupid ANSI 24 hours in a day .... 24 beer in a case .... coincidence? Reply With Quote 04-07-2004,10:13 AM #4 samdba View Profile View Forum Posts Advisor Join Date Dec 2001 Location USA Posts 620 Folks, I figured it out. In one of the table, attribute3 column has 'NA' value in it, which it is not able to convert into number. So, I used DECODE and now it is not giving the error. This is true that it is giving error only if I use PARALLEL hint. This certainly looks like a bug. We are using 8.1.7.4.13 on Windows platform. Thanks, Sam ------------------------ To
