ORA-4030 errors are raised when memory or resources are requested from the

Operating System and the Operating System is unable to provide the memory or resources. The arguments included with the ORA-4030 are

often important to narrowing down the problem. For more specifics on the ORA-4030 error and scenarios that lead to this problem, see Note 399497.1 FAQ ORA-4030. Looking for the best way to diagnose? There

are several available diagnostic tools (error tracing, 11g Diagnosibility, OCM, Process Memory Guides, RDA, OSW, diagnostic scripts) that collectively can prove powerful for identifying the cause of the ORA-4030. Error Tracing The ORA-4030 error usually occurs on the client workstation and for this reason, a trace file and alert log entry may not have been generated on the server side. It may be necessary to add additional tracing events ora-04030 out of process memory when trying to allocate 16328 bytes to get initial diagnostics on the problem. To setup tracing to trap the ORA-4030, on the server use the following in SQLPlus: alter system set events '4030 trace name heapdump level 536870917;name errorstack level 3';Once the error reoccurs with the event set, you can turn off tracing using the following command in SQLPlus:alter system set events '4030 trace name context off; name context off';NOTE: See more diagnostics information to collect in Note 399497.1 11g DiagnosibilityStarting with Oracle Database 11g Release 1, the Diagnosability infrastructure was introduced which places traces and core files into a location controlled by the DIAGNOSTIC_DEST initialization parameter when an incident, such as an ORA-4030 occurs. For earlier versions, the trace file will be written to either USER_DUMP_DEST (if the error was caught in a user process) or BACKGROUND_DUMP_DEST (if the error was caught in a background process like PMON or SMON). The trace file may contain vital information about what led to the error condition.

not like my expectation. That's why I'm posting this article - to help them play with ORA-4030 and have an https://dioncho.wordpress.com/2009/07/27/playing-with-ora-4030-error/ insight on it! Look at this definition. 04030 "out of process http://adminoracle10g.blogspot.com/2013/05/ora-04030-out-of-process-memory-when.html memory when trying to allocate %s bytes (%s,%s)" // *Cause: Operating system process private memory has been exhausted // *Action: It clearly says that this is OS process private memory problem! But I believe that this statement is 50% of truth. As far as I know, there out of are 3 common reasons for this error. You have under-configured OS memory limitation. You have memory leak bug. You are allocating too many objects. In the Unix system, the low limit of the process configuration can cause ORA-4030 error. The quick cure is to increase the limit - the most prefered value is UNLIMITED. prompt> ulimit -a core file out of process size (blocks, -c) 0 data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 stack size (kbytes, -s) unlimited cpu time (seconds, -t) unlimited max user processes (-u) 7168 virtual memory (kbytes, -v) unlimited In the Windows 32 system, the limit of the private memory is around 1.5G. You cannot grow your process memory over than it regardless of your physical RAM size. For this reason, it's somtimes recommended to use the Windows 64 system. If the problem persists even with the higher OS configuration, you have 2 other reasons. You're hitting Oracle bug(memory leak) and/or allocating too many objects. The most intuitive and natural way for further investigation is the PGA heap dump. As far as I know, this is the easiest way! Before introuducing how to use PGA heap dump, you should understand exactly when you hit ORA-4030 error. Let me show you simple examples. 1. I have fol
unable to allocate more memory from the operating system.This memory consists of the PGA (Program Global Area) and its contents depend upon the server configuration.For dedicated server processes it contains the stack and the UGA (User Global Area) which holds user session data, cursor information and the sort area. In a multithreaded configuration (shared server), the UGA is allocated in the SGA (System Global Area) and will not be responsible for ORA-4030 errors. What causes this error? Since you run into this error, you can't allocate memory from the operating system. This could be caused by your process itself, like your process is just requesting too much memory, or some other reasons cause the operating system memory to be depleted, like a too big SGA or too many processes to be accomodated for the systems virtual memory (physical memory + swap space). Many operating systems impose limits on the amout of memory a single process can acquire to protect itself.This leads to the following questions: Is there an operating system limit set? You can check limit information's using >ulimit -a and find the information related to memory using vmstat vmstat procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu------ r b swpd free buff cache si so bi bo in cs us sy id wa st 1 0 5511440 243988 213924 92768888 1 1 1860 639 0 0 7 0 91 2 0 vmstat output contains the following fields: Procs - r: Total number of processes waiting to run Procs - b: Total number of busy processes Memory - swpd: Used virtual memory Memory - free: Free virtual memory Memory - buff: Memory used as buffers Memory - cache: Memory used as cache.

It's usually a good idea to confirm the process memory usage from the Operating System point
