PL/SQL连接查询数据报错时Dynamic Performance Tables not accessible

一、产生该提示原因
plsql dev在用户运行过程中，要收集用户统计信息，但是由于你现在登录的用户没有访问v$session,v$sesstat and v$statname视图的权限，所以不能收集当前用户的统计信息，和plsql dev工具中配置的Automatic Statistics相冲突，所以就出现了这个提示，试验验证：

[oracle@xifenfei ~]$ sqlplus / as sysdba

chf@XFF>SELECT TABLE_NAME FROM USER_TAB_PRIVS;

 

no rows selected

创建一个chf用户，授权create session,resource，无v$session,v$sesstat and v$statname视图访问权限，使用plsql dev登录并查询user_tables表(登录时不会提示，只有用户执行了查询或者相关类此操作时候才会提示)

二、解决问题
根据警告提示，可以有两种方法解决这种警告
1、关闭plsql dev统计功能
在 Tools->Preferences->Options里把Automatic Statistics前的那个勾子去掉，保存
2、给访问用户授权访问相关视图
授权访问v_$session,v_$sesstat,v_$statname,注意不能直接对v$视图进行授权

chf@XFF>conn / as sysdba

Connected.

sys@XFF>grant select on v_$session to chf;

 

Grant succeeded.

 

sys@XFF>grant select on v_$sesstat to chf;

 

Grant succeeded.

 

sys@XFF>grant select on v_$statname to chf;

 

Grant succeeded.

 

sys@XFF>conn chf/xifenfei

Connected.

 

chf@XFF>SELECT TABLE_NAME FROM USER_TAB_PRIVS;

 

TABLE_NAME

------------------------------

V_$SESSION

V_$SESSTAT

V_$STATNAME
