劳烦给解释一下为什么，能不能修改，其他页面都正常，就是这个页面，是不是因为oracle的启动参数不合理

[kostion]

我把oracle的启动参数也贴上来了，帮忙看一下
.aq_tm_processes=1
*.background_dump_dest='/orasoft/admin/adsys/bdump'
*.compatible='9.2.0.0.0'
*.control_files='/orasoft/oradata/adsys/control01.ctl','/orasoft/oradata/adsys/control02.ctl','/orasoft/oradata/adsys/control03.ctl'

*.timed_statistics=TRUE
*.undo_management='AUTO'

帮忙看一下是不是哪个参数不对呢
*.user_dump_dest='/orasoft/admin/adsys/udump'

[kostion]

代码的功能是页面的java小程序访问数据库，普通的查询页面是正常的，就是页面小程序不行，应该是applet吧，不很懂java

[kostion]

ORA-02291: 违反完整约束条件
oracle的启动参数错误,有没有可能导致这个错误, 比如说sga和pga设置不合理

[iqlife]

1:首先确认数据库实例是否启动
2：确认监听是否配置和启动
3：确认数据库连接字符串是否正确

[opps_zhou]

你的代码是实现什么功能的？

17002
You cannot exclude 
everything from being replicated.
All objects in the database were excluded in the CREATE REPLICATION statement. There must be at least one object in the database.

[liaochangfa]

可以肯定，监听没配置好！
找到 listener.ora
在sid_list_listener 后加入
(SID_DESC =
(GLOBAL_DBNAME = 实例)
(ORACLE_HOME =d:\oracle\product\10.2.0\db_1)
(SID_NAME = 实例)
)
