SQL> conn scott/scott;
想要打开autotrace的时候报错:
SQL> set timing on
SQL> set autotrace traceonly
SP2-0618: Cannot find the Session Identifier. Check PLUSTRACE role is enabled
SP2-0611: Error enabling STATISTICS report
解决办法:
SQL> conn / as sysdba;
Connected.
SQL> select * from dba_roles where role='PLUSTRACE';
no rows selected
该数据库中目前不存在该角色,需要创建:
SQL> @?/sqlplus/admin/plustrce.sql
将该角色赋予scott用户:
SQL> grant plustrace to scott;
Grant succeeded.
SQL> conn scott/scott;
Connected.
SQL> set autotrace traceonly
但在查看执行计划的时候依然报如下错误:
Execution Plan
----------------------------------------------------------
ERROR:
ORA-01039: insufficient privileges on underlying objects of the view
SP2-0612: Error generating AUTOTRACE EXPLAIN report
需要授予scott用户查看数据字典的权限:
SQL> grant select any dictionary to scott;
Grant succeeded.
附:
plustrce.sql脚本的内容:
SQL> host cat $ORACLE_HOME/sqlplus/admin/plustrce.sql
