OCIStmtExecute: ORA-04031: unable to allocate 4200 bytes of shared memory (“shared pool”,”unknown object”,”sga heap”,”state objects”)
More shared memory is needed than was allocated in the shared pool.
Bug on Oracle 188.8.131.52
metalink suggest to set the parameter _db_handles_cached=0
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”.
