ORA-04031 solution Oracle Error Tips by Burleson Consulting Updated February 24, 2016 ora-04031 solution Oracle docs note this about ORA-04031: ORA-04031: unable to allocate string bytes of shared memory Cause: More shared memory is needed ora-04031 unable to allocate 4160 bytes of shared memory 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$SGASTAT where pool='LARGE POOL' group by ROLLUP(name); Though the number of bytes may vary, ORA-04031 is commonly thrown in operations with configured large pools. The exampled select above offers a summary of the number of bytes which will reveal the current pool size and you proximity to the maximum pool size which is specified within the LARGE_POOL_SIZE parameter. You will find that when the LARGE_POOL is increased up to 100%, ORA-04031 will typically be eliminated. To help you to understand more clearly the impact that large pool sizing can have in resolving ORA-04031, you may be interested in the statement below: Sizing the large pool can be complex. The large pool, if configured must be at least 600 kilobytes in size. Usually for most MTS applications 600k is enough. However, if PQO is also used in your Oracle8 environment then the size of the large pool will increase dramatically. The V$SGASTAT dynamic performance view has a new column in Oracle8, POOL. The POOL column in the V$SGASTAT view is used to contain the pool area where that particular type of object is being stored. By issuing a summation select against the V$SGASTAT view a DBA can quickly de
