Ora-04030 Error
problem related to ORA-04030. Thanks Ajay Goel and we said... add more memory (I ora-04030 oracle 11g did not even have to look that one up, unable to allocate X bytes of process memory) Whatever you were doing hit
Oracle 12c Ora-04030
the limit on OS memory that could be allocated to you. There could be many causes of this o you write a plsql function like this: declare type array is table of long index by ora-04030 out of process memory 11g binary_integer; l_data array; begin loop l_data(l_data.count+1) := rpad('*',32000,'*'); end loop; end; o you could be setting your pga aggregate target too high, higher then the system will allocate memory o you could be running on 32bit windows and are just hitting a windows limit because you have too many sessions o you might have ulimit set too low on your unix system and ulimit is artificially restricting the amount of memory how to increase pga_aggregate_target in oracle 11g you can allocate o and so on...... But basically - given the question "how do you solve ora-4030", the only casual answer possible is "get more memory or reduce your need for memory". Given that I have no context, nothing to work with, no example, no "we were doing this" - that's all we can say.... Reviews Write a Review some more thoughts on this please January 05, 2009 - 11:38 am UTC Reviewer: reader from India Dear Tom, as you have listed few out of many issues that can cause ora-04030 error, can we calculate memory useage of each session and adding all of this can we arrive at approx memory need on the DB server. I understand from you point that on Windows box (32 bit) we may hit windows limit if too many sessions are active. But if we get rough estimate of the memory required then it will help to say that how much more we need. If you can please share how to get memory useage of each session, here I do understand that it's poosible that one of the stored procedure executed may ask much more memory than other procedures/sessions, but if you can please share your thoughts on this. Thanking you in advance for

ora-04030 solution ORA-04030: out of process memory Tips Oracle Database TipsOra-04030 Out Of Process Memory When Trying To Allocate 16328 Bytes
by Burleson Consulting
Question: On an auto execute of an external job I get the error "ORA-04030: out of process memory when trying to allocate nn bytes". Answer: https://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1363891100346045112 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 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 http://www.dba-oracle.com/t_ora_04030_out_process_memory.htm 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?"

First we will see out of what ORA-4031 actually means. 04031, 00000, "unable to allocate %s bytes of shared memory (\"%s\",\"%s\",\"%s\,\"%s\")" // *Cause: More shared memory is needed than was allocated in the shared pool. // *Action: If the shared pool is out of memory, either use the // dbms_shared_pool package to pin large packages, // reduce your use of shared memory, or increase the amount out of process of // available shared memory by increasing the value of the // INIT.ORA parameters "shared_pool_reserved_size" and // "shared_pool_size". // If the large pool is out of memory, increase the INIT.ORA // parameter "large_pool_size". ORA-4031 error is encountered when we do not have sufficient memory available in shared pool/large pool to service a memory request. But in actual ORA – 4031 can be encountered in any of these areas 1) Shared pool 2) Large Pool 3) Java Pool 4)Streams pool (new to 10g) This brings us to the first step in our pursuit for finding the cause for ORA -4031. Step1: Identify the Pool associated with error Like any other Oracle error, we first need to check Database Alert Log file and also any trace files which gets generated during that time in user_dump_dest,background_dump_dest. Though there are cases when ORA-4031 error is not recorded in alert.log. Starting from 9.2.0.5, you should be able to see trace files which gets generated in udump/bdump location (Depending on whether background process or user process encountered the error). ORA – 4031 has basically th
