ora-04031 solution ORA-04031: unable to allocate nn bytes of shared memory Oracle Database Tips by Burleson Consulting July 17, 2015 - Updated February 24, 2016 Question:Ora-04031 Unable To Allocate 4160 Bytes Of Shared Memory
I am getting the error ORA-04031 Cannot allocate shared memory. I've tried increasing my init.ora shared_pool_size, but to no avail. What are some causes for the ORA-04031 error, and how do I fix it?Answer: The ORA-04031 error has many root causes. Also, see MOSC notes 146599.1 and 396940.1 for more ora-04031 oracle 11g details for resolving the ORA-04031 error: Heavy fragmentation of the shared pool - This can be fixed by increasing the shared_pool_size or doing a "alter system flush shared pool" or bouncing the instance. Too many pinned packages - If you have pinned lots of packages with dbms_shared_pool.keep, they have not leave enough room for new work. Ultimately the solution to a ORA-04031 error is adding RAM to shared_pool_size and/or shared_pool_reserved_size. In 11g and beyond , if using AMM, increase memory_max_size to resolve the ORA-04031 error. The Oracle documentation has these notes on the ORA-04031 error: ORA-04031: unable to allocate nn bytes of shared memory 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 of available shar

memory is unavailable for use or reuse in the System Global Area (SGA). The error message will indicate the memory pool alter system flush shared pool getting errors and high level information about what kind of allocation failed and how much memory was unavailable. The challenge with ORA-4031 analysis is that the error and associated trace is for a "victim" http://www.dba-oracle.com/t_ora_04031_unable_to_allocate_shared_memory.htm of the problem. The failing code ran into the memory limitation, but in almost all cases it was not part of the root problem. Looking for the best way to diagnose? When an ORA-4031 error occurs, a trace file is raised and noted in the alert log if the process experiencing the error is a background process. User processes may experience errors without reports in the alert log or https://blogs.oracle.com/db/entry/ora-4031_troubleshooting traces generated. The V$SHARED_POOL_RESERVED view will show reports of misses for memory over the life of the database. Diagnostics scripts are available in Note 430473.1 to help in analysis of the problem. There is also a training video on using and interpreting the script data Note 1087773.1. 11g Diagnosibility Starting 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-4031 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 contains vital information about what led to the error condition.

I don't know if this is a simple server setup problem or an application design problem (or both). Once or twice every few months this Oracle XE database reports ORA-4031 errors. It doesn't point to any particular part of the sga consistently. A recent example is: ORA-04031: unable to allocate 8208 bytes of shared memory ("large pool","unknown object","sort subheap","sort key") When this error unable to allocate comes up, if the user keeps refreshing, clicking on different links, they'll generally get more of these kinds of errors at different times, then soon they'll get "404 not found" page errors. Restarting the database usually resolves the problem for a while, then a month or so later it comes up again, but rarely at the same location in the program (i.e. it doesn't seem linked to any particular portion of code) (the above example error was raised from an Apex page which was sorting 5000+ rows from a table). I've tried increasing sga_max_size from 140M to 256M and hope this will help things. Of course, I won't know if this has helped since I had to restart the database to change the setting :) I'm running Oracle XE 10.2.0.1.0 on a Oracle Enterprise Linux 5 box with 512MB of RAM. The server only runs the database, Oracle Apex (v3.1.2) and Apache web server. I installed it with pretty much all default parameters and it's been running quite well for a year or so. Most issues I've been able to resolve myself by tuning the application code; it's not intensively used and isn't a business critical system. These are some current settings I think may be relevant: pga_aggregate_target 41,943,040 sga_max_size 268,435,456 sga_target 146,800,640 shared_pool_reserved_size 5,452,595 shared_pool_s

You can temporarily fix the problem by flushing the shared pool with: alter system flush shared_pool; There's a workaround you can try to stop it happening in the future. Turn on cursor sharing, then bounce the database: ALTER SYSTEM SET cursor_sharing='SIMILAR' SCOPE=BOTH; The only real way of fixing this is to rewrite your application so that it uses bind variables. share|improve this answer answered Feb 1 '12 at 12:59 Philᵀᴹ 20.9k54269 "then bounce the database" ==?
