如果在启动数据库时遇到ORA-32004: obsolete and/or deprecated parameter(s) specified 错误，这个是因为数据库里面设置了过时或不推荐使用的参数，如下描述所示：
SQL> ho oerr ora 32004
32004, 00000, "obsolete and/or deprecated parameter(s) specified"
// *Cause: One or more obsolete and/or parameters 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.
具体怎么排除和解决呢？ 那么我们先从下面例子来，注意，这个仅仅是在测试服务器用作测试的案例。
SQL> ALTER SYSTEM SET SQL_TRACE=TRUE;
System altered.
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup
ORA-32004: obsolete and/or deprecated parameter(s) specified
ORACLE instance started.
