java 内存溢出
下面是我的代码，大家看看，是啥原因造成的内存溢出啊，数据一跑到9700+就溢出了。
我的设置是set JAVA_OPTS=-Xms64m -Xmx512m
代码：
public class Ods_main {
private static String id = "";
private static String ztbs = "";
private static String PK_HJ ="";//判断参数合计 
private static Connection db2Conn = DBConnection.getDB2Connection();
 
private static Log log = LogFactory.getLog(Ods_main.class);
public static void main (String[] arg)
{
try {
 

String sql_getztbs = "select nextval for ods.SEQ_ods as id ,bs from topicis.dj_zt where " +
"bs not in (select ztbs from ods.ods_lsjl where xybz='Y' )" +
"and qylx_dm!='04'";
  Statement stmtgetztbs = db2Conn.createStatement();
ResultSet rsgetztbs = stmtgetztbs.executeQuery(sql_getztbs);
int bz = 0;//失败计数
int js = 0;//遍历条目计数，包括成功和失败
String time = java.text.DateFormat.getDateTimeInstance().format(new java.util.Date());
// String time=new java.util.Date().toString() ;
log.info("运行时间:" + time + ".");
while (rsgetztbs.next())

{
id = rsgetztbs.getString(1); 
ztbs = rsgetztbs.getString(2);
 
// 调试-
// ztbs ="340000000004344368";
