ORA-04031 unable to allocate string bytes of shared memory ("string","string","string","string")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 shared memory by increasing the value of the initialization parameters SHARED_POOL_RESERVED_SIZE and SHARED_POOL_SIZE. If the large pool is out of memory, increase the initialization parameter LARGE_POOL_SIZE.
另外再请问SQL level 3 是什么东西？
这个信息表明，在数据库执行内部SQL语句时，发生了错误.
其中 SQL level 3表示(Structured Query Language)标准3,即在执行使用SQL标准3的语句.
比如，要往表中插入一行数据，但没有可扩展的空间。ORACLE于是去查寻，哪儿可以建立下一个扩展空间，它有多大小，但没有成功。一般在发生ORA-00604错误时，还伴随着其它的错误.
