Ora-04031 Unable To Allocate 4160 Bytes Of Shared Memory
unable to allocate string 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 ora-04031 oracle 11g 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 pro

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 comes up, if the user keeps refreshing, clicking on different unable to allocate 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_size 104,857,600 If it's any help here's the current SGA sizes: Total System Global Area 268435456 bytes Fixed Size 1258392 bytes Var
