db2小用

db2真是不好用(8.0.?)

难道升级版会好一些？无语

1>update超级慢....(这点还不如access,175万记录)

2>execute immediate 不支持基本的export 和output(貌似也没有在oracle里面测试过这个功能)

打升级补丁后可以

3>周边工具少,安装繁琐.

4> inner join 的update不支持

5>connect to db  不需要密码,多个库公用一个密码..

为什么做事情不可以变通一些呢？又是规矩作祟，呵呵。

jdbc远程连接失败...

连接代码

public static void main(String[] args) throws ClassNotFoundException, SQLException {
  // TODO Auto-generated method stub
  Class.forName("com.ibm.db2.jcc.DB2Driver");

  // connect
  Connection db2Conn =DriverManager.getConnection(
  "jdbc:db2://***.***.***.***:50001/dbname",
  "instname",
  "passwd");
 
  Statement st = db2Conn.createStatement();
  String queryStr ="SELECT a.id FROM tabletest a order BY a.ID";
  ResultSet resultSet = st.executeQuery(queryStr);
  while (resultSet.next())
  {
        string id = resultSet.getString( "ID" );
        System.out.println( id );
  }
  resultSet.close();
  st.close();
  db2Conn.close();  
 }

---------------------------------------search 结果---------------------------------------------------------------

Try this. This works if password is expired by OS.
connect to sample user db2inst1 using xxxx new xxxxx confirm xxxxxx

db2 grant connect, createtab, bindadd on database to user celiacy

This is known problem when using DB2 8.2 and AIX5.3
(don't know if already fixed in newer fix packs)
If you use this db2set setting and restart the instance the problem is
"solved":
db2set DB2_NUM_CKPW_DAEMONS=0
