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

解決:增加數據庫存內存大小，一定注意服務器本身內存，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.
