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, ora-04030: out of process memory when trying to allocate 169040 bytes (pga heap,kgh stack) cursor information and the sort area. In a multithreaded configuration (shared server), the UGA is allocated

Ora-04030: Out Of Process Memory When Trying To Allocate 16328 Bytes (koh-kghu Call ,pmucalm Coll)
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 https://community.oracle.com/thread/618214 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 http://adminoracle10g.blogspot.com/2013/05/ora-04030-out-of-process-memory-when.html 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 on what the pr
