重启数据库时出现如下情况：
SQL> startup

[oracle@DBA2 ~]$ oerr ora 32004
32004, 00000, "obsolete or deprecated parameter(s) specified for %s instance"
// *Cause: Obsolete or deprecated parameters for this instance type
// were specified in the SPFILE or the PFILE on the server side.
// *Action: See alert log for a list of parameters that are obsolete
// or deprecated. Remove them from the SPFILE or the server
// side PFILE.
Spfile /u/oracle/product/11.2/dbs/spfileorcl2.ora is in old pre-11 format and compatible >= 11.0.0; converting to new H.A.R.D. compliant format.
Deprecated system parameters with specified values:
sql_trace
由于这个库是自己用的实验测试库，前一阶段一直在做SQL的语法分析和执行计划相关的实验，所以打开了sql_trace
查看数据库弃用的系统参数：
SQL> select name from v$parameter where isdeprecated = 'TRUE';

通过修改pfile启动参数来重建spfile：
[oracle@DBA2 dbs]$ vi initorcl2.ora
将其中的sql_trace项注释掉或者直接删除
SQL>create pfile from spfile;
然后重新启动数据库：
SQL> startup
ORACLE instance started.
