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 slaves. Additionally, your tables should account for the parallel query. Run a full table scan to assess the timing of various settin

Add datafile to tablespace usr_tmp to increase its size. 0 LVL 3 Overall: Level 3 Message Author Comment by:harsha_dp2004-06-18 Is there a upper limit for the available memory at any time.. This is to decide when to use datafile. As we have some estimate about temporary space that the query uses during execution, if we know the limit we can dynamically program the things, I believe. I am using SAS , so i can fix up the upper bound before query execution. 0 LVL 13 Overall: Level 13 Oracle Database 12 Message Expert Comment by:riazpk2004-06-18 No this is not Memory-related issue. Just set autoextend property of database file (in tablespace usr_tmp to ON and the datafile will grow as much as it needed. Also you can change maxsize (the maxmimum limit a datafile can grow automatically if the autoextend on) to unlimited. Like: alter database datafile 'DataFileNameWithFullPath' autoextend on 10M Maxsize 1000M; Here is said to autoextend by 10M but upto the max of 1000M. Alternatively: alter database d

A Windows error is an error that happens when an unexpected condition occurs or when a desired operation has failed. When you have an error in Windows, it may be critical and cause your programs to freeze and crash or it may be seemingly harmless yet annoying.
A stop error screen or bug check screen, commonly called a blue screen of death (also known as a BSoD, bluescreen), is caused by a fatal system error and is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to "crash".
One of the biggest causes of DLL's becoming corrupt/damaged is the practice of constantly installing and uninstalling programs. This often means that DLL's will get overwritten by newer versions when a new program is installed, for example. This causes problems for those applications and programs that still need the old version to operate. Thus, the program begins to malfunction and crash.
Computer hanging or freezing occurs when either a program or the whole system ceases to respond to inputs. In the most commonly encountered scenario, a program freezes and all windows belonging to the frozen program become static. Almost always, the only way to recover from a system freeze is to reboot the machine, usually by power cycling with an on/off or reset button.
Once your computer has been infected with a virus, it's no longer the same. After removing it with your anti-virus software, you're often left with lingering side-effects.
