Ora-04031 Unable To Allocate 4160 Bytes Of Shared Memory
ORA-04031 solution Oracle Error Tips ora-04031: unable to allocate 65560 bytes of shared memory by Burleson Consulting Updated February 24, 2016 Oracle docs note this about ORA-04031: ORA-04031: unable to allocate string bytes of shared memory Cause: More shared memory ora-04031 oracle 11g 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 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". There are many valuable resources regarding shared pool sizing, and ORA-04031 is very commonly encountered in situations involving the sizing of large pools. Below is an excerpt from an the article, Oracle Concepts - Shared Pool and Multi-Threaded Server (MTS) in which ORA-04031 is addressed and offered a resolution. If ORA-04031 is thrown, consider using the following select: select name, SUM(bytes) from V$SGASTAT where pool='LARGE POOL' group by ROLLUP(name); Though the number of bytes may vary, ORA-04031 is commonly thrown in operations with configured large pools. The exampled select above offers a summary of the number of bytes which will reveal the current pool size and you proximity to the maximum pool size which is specified within the LARGE_POOL_SIZE parameter. You will find that when the LARGE_POOL is increased up to 100%, ORA-04031 will typically be eliminated. To help you to understand more clea

There are two oracle

databases on it. At least 2 identical schema owners on each of them. Each scema has on an average about 10 pl/sql packages of about 1000 lines each. I http://www.dba-oracle.com/sf_ora_04031_unable_to_allocate_string_bytes_of_shared_memory.htm have separated two databases as D (Development) and Q (For our own internal testing). Also there is a JRUN server, and a Netscape Enterprise Server running on the same box. My SGA: Total System Global Area 24899532 bytes Fixed Size 65484 bytes Variable Size 7983104 bytes Database Buffers 16777216 bytes Redo Buffers 73728 bytes Some of the pfile Parameters: https://asktom.oracle.com/pls/asktom/f?p=100:11:0::::p11_question_id:528893984337 db_block_size integer 8192 db_block_buffers integer 2048 shared_pool_size string 5000000 shared_pool_reserved_size string 250000 shared_pool_size string 5000000 Problems Encountered: Our developers are using servlet applications, and our testers are banging against the database pretty hard. I have to restart the server at least once or twice every day due to shared memory errors such as the one below. Our QC and Production environments will be dedicated Oracle servers running on Solaris boxes with much better resource allocations. Any help on how to eliminate/mitigate this problem will be greatly appreciated.

(I dont want to shutdown the DB nor want to increase size of shared pool) Previously Same issue Came : I left with option to SHUTDOWN DB. So after STARTUP , when i connected through SYSDBA and executed same query alter system flush shared_pool; That time it works perfectlly fine. So question remains as why ORACLE is not allowing flush shared pool when it is out of memory ?

Then edit your question and add OS platform. And then you also should check installation guide - memory sizing. –ibre5041 Mar 10 '15 at 12:16 whether different OS will behave differently on this ? –Nagendra Nigade Mar 10 '15 at 12:18 sure. You have to check SGA sizing against OS limits. –ibre5041 Mar 10 '15 at 12:20 oh no sry. this has nothing to od with OS limits. I was wrong. You probably have an application which parses too many SQL statements and Oracle is unable to allocate more ram for library cache. –ibre5041 Mar 10 '15 at 12:22 Ya..exctaly..After certain
