ORA-04030: out of process memory Tips Oracle Database Tips by Burleson Consulting
Question: On an auto executeOra-04030 Solution
of an external job I get the error "ORA-04030: out of process memory when trying to allocate nn bytes". Answer: This ORA-04030 can be caused by a shortage of RAM on a dedicated (non shared server) environment, a too small PGA, and by not setting kernel parameters ora-04030 out of process memory when trying to allocate 64544 bytes (sort subheap sort key) large enough to allow enough RAM. The ORA-04030 is also common when running an import. See import ORA-04030 error tips. Also see MOSC Note 233869.1 titled "Diagnosing and Resolving ORA-4030 errors". Essentially the ORA-04030 is clear, and "out of process memory" error, whereby Oracle cannot get the RAM needed to complete the operations. Depending on your release of Oracle, you have several options: Increase pga_aggregate_target Decrease sort_area_size and/or hash_area_size Move to multi-threaded server (a.k.a. MTS or shared servers) Kernel Parms - (Karpinski, Joseph E) In installing Oracle 10G we ran into a number of ORA-4030 issues. We changed the setting of "ulimit" as follows to resolve the issue: ulimit –a time(seconds) unlimited file(blocks) unlimited data(kbytes) unlimited stack(kbytes) 4194302 memory(kbytes) unlimited coredump(blocks) unlimited nofiles(descriptors) 4096 It's also part of the Oracle 10G pre-install checklist: Section "ULimits OK?" F
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 ora-04030 out of process memory when trying to allocate 16328 bytes data, cursor information and the sort area. In a multithreaded configuration (shared server), the UGA is allocated ora-04030 12c 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, ora-04030: out of process memory when trying to allocate 169040 bytes (pga heap,kgh stack) 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 http://www.dba-oracle.com/t_ora_04030_out_process_memory.htm 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 http://adminoracle10g.blogspot.com/2013/05/ora-04030-out-of-process-memory-when.html 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 of view. After all, it might no be an oracle server process that is using too much memory.Usually, for server processes, oracle and the operating system more or less agree on memory usage. The following command will allow you to find out the memory usage for processes from the operating system. SELECT SID,NAME,VALUE FROM v$statname n,v$sesstat s WHERE n.STATISTIC# = s.STATISTIC# AND NAME LIKE 'session%memory%' ORDER BY 3 ASC; How to collect information

I am trying to implement the #WF_REASSIGN_LOV logic and ran into an issue when the workflow kicked off. I got the following error:ORA-04030: out of process memory when trying to allocate 21528 bytes (PLS non-lib hp, PL/SQL STACK)ORA-06500: PL/SQL: storage errorORA-04030: out of process memory when trying to allocate 16408 bytes (koh-kghu call ,pmucalm coll)Any idea what this could be? Also, I saw another post where you refer to the Technical Tips (specifically looking up Debugging Functions in Workflow) but I'm not sure where the Technical Tips are!Thanks,S.

This message// normally appears with an ORA-4030 or ORA-4031 error which gives// additional information. Sometimes this error can be caused by// runaway programs.// *Action: 1) Ensure there are no issues or bugs in your PL/SQL program which// are causing excessive amounts of memory to be used.// 2) Programmatically cause unused objects to be freed (e.g. by// setting them to NULL).// 3) Increase the amount of shared or process memory (as appropriate)// available to you.ORA-04030:// *Cause: Operating system process private memory has been exhaustedLooks like something is chewing up all the memory available and then blowing up - I have to say that I've never seen it before, though. It's not specific to Workflow, thoguh, so your DBA should be able to help debug the problem.There used to be a "Technical Tips" board, but I moved everything onto my (hopelessly out of date and not updated very often) blog - http://thoughts.workflowfaq.com It's a sign of how busy I've
