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.

修改SQL_TRACE参数的值后，关闭实例，重启实例是报错：ORA-32004，一般如果遇到ORA-32004错误时，首先查看告警日志记录，你会发现在告警日志里面有这么一段信息。

Deprecated system parameters with specified values:

  sql_trace               

End of deprecated system parameter listing

另外，你也可以通过下面SQL查看相关过时或不推荐设置的参数。

SQL> SELECT  NAME, DESCRIPTION FROM V$PARAMETER V WHERE V.ISDEPRECATED='TRUE';

NAME                                                                DESCRIPTION

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

lock_name_space                        lock name space used for generating lock names for standby/clone database

buffer_pool_keep                       Number of database blocks/latches in keep buffer pool

buffer_pool_recycle                    Number of database blocks/latches in recycle buffer pool

max_commit_propagation_delay           Max age of new snapshot in .01 seconds

remote_archive_enable                  remote archival enable setting

log_archive_start                      start archival process on SGA initialization

parallel_server                        if TRUE startup in parallel server mode

parallel_server_instances              number of instances to use for sizing OPS SGA structures

fast_start_io_target                   Upper bound on recovery reads

logmnr_max_persistent_sessions         maximum number of threads to mine

serial_reuse                           reuse the frame segments

max_enabled_roles                      max number of roles a user can have enabled

global_context_pool_size               Global Application Context Pool Size in Bytes

plsql_compiler_flags                   PL/SQL compiler flags

sql_trace                              enable SQL trace

parallel_automatic_tuning              enable intelligent defaults for parallel execution parameters

drs_start                              start DG Broker monitor (DMON process)

另外，我们来看看一个使用过时参数的案例，例如，在设置了参数log_archive_start后，重启就会遇到ORA-32004: obsolete and/or deprecated parameter(s) specified

SQL> ALTER SYSTEM SET LOG_ARCHIVE_START=TRUE SCOPE=SPFILE;

此时查看告警日志，就会看到下面对应信息，那么就可以确认是参数log_archive_start的问题。

Deprecated system parameters with specified values:

  log_archive_start

End of deprecated system parameter listing

此时执行下面SQL语句，即可解决这个问题。

SQL> alter system reset log_archive_start scope=spfile sid='*';

System altered.
