java连接oracle报错:java.sql.SQLException: ORA-04031: unable to allocate 4200 bytes of shared memory ("shared pool","unknown obje

我需要将oracle表中的数据导入到sql server表中，运行如下程序一段时间后，报错：java
java.sql.SQLException: ORA-04031: unable to allocate 4200 bytes of shared memory ("shared pool","unknown object"1.是否是oracle自身设置问题，比如说需要增加shared memory?
2.程序本身有问题？public void run(){
System.out.print("Starting Service......");
