问题:ORA-04031: unable to allocate 12312 bytes of shared memory ("shared pool","unknown object","KKSSP^405","kglseshtTable")

解决:增加数据库存内存大小，一定注意服务器本身内存，不是任意

SQL> alter system set memory_max_target=2G scope=spfile;

System altered.

SQL> alter system set memory_target=2G scope=spfile;

System altered.

查看修改结果：

SQL> show parameter memory
