1)启动hp-unix下oracle时出现如下所示:
Oracle Server Manager Release 3.1.7.0.0 - Production
Copyright (c) 1997, 1999, Oracle Corporation. All Rights Reserved
Oracle8i Enterprise Edition Release 8.1.7.2.0 - 64bit Production
With the Partitioning option
JServer Release 8.1.7.2.0 - 64bit Production
SVRMGR> Password:

ORA-01031: insufficient privileges
SVRMGR> ORA-01031: insufficient privileges
SVRMGR>
Server Manager complete.

#
显示权限不够;用root去启动oracle当然是不行的;
2)col 用法
col子命令中有两个参数：truncated 和 wrapped，col定义的显示行的宽度，truncated就是如果行超过显示宽度就截断，wrapped就是换行！

我们先看如下的一系列执行：

2 select *
3 from ;
SQL> create or replace procedure sp_v_test is
2 v_id number;
3 begin
4 select id into v_id from v_bmw_pay_online_new where id=1;
5 end;
6 /
Procedure created

2 for ;

3 begin
4 select id into v_id from s_bmw_pay_online_new where id=1;
5 end;

可以看到，在同样一个远程对象上面，我可以通过创建视图，然后在该视图上创建存储过程，是没有任何问题的，
但是如果我对该远程操作做一个同义词，再在同义词上创建存储过程，则报出了Ora-00600。跟踪也无果，
看产生的日志文件也不能看出来什么，上metalink，搜索"ora-00600 17069"，发现查出现的东西一大堆，
大致是library cache错误，但是到底怎么会产生这个错误呢，online联系上一个oracle在线技术支持，聊了一会儿，
问题是解决了，但是他就是不承认是bug，呵呵。
以下是聊天的总结：
ORA-00600 [17069] reorted on compiling a procedure.
Invalid lock in library cache.
Unable to pin the object and hence the Error.
"Failed to pin a library cache object after 50 attempts"
Clearing the shared memory will help to get rid of inconsistant information
in memory which is causing the error.
The inconsistency was suspected to be in the remote site. But flushing the
shared pool in remote location didnt help.Tried recreation of the procedure
after dropping and recreating the synonym in the local database. But the
same failed.Flushed the shared pool in local database abd successfully
created the procedure.
alter system flush share_pool;
