如果在啟動數據庫時遇到ORA-32004: obsolete and/or deprecated parameter(s) specified 錯誤，這個是因為數據庫裡面設置了過時或不推薦使用的參數，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.
具體怎麼排除和解決呢？ 那麼我們先從下面例子來，注意，這個僅僅是在測試服務器用作測試的案例。
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參數的值後，關閉實例，重啟實例是報錯：ORA-32004，一般如果遇到ORA-32004錯誤時，首先查看告警日志記錄，你會發現在告警日志裡面有這麼一段信息。
Deprecated system parameters with specified values:
sql_trace
End of deprecated system parameter listing
另外，你也可以通過下面SQL查看相關過時或不推薦設置的參數。
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)
17 rows selected
SQL> ALTER SYSTEM SET LOG_ARCHIVE_START=TRUE SCOPE=SPFILE;
此時查看告警日志，就會看到下面對應信息，那麼就可以確認是參數log_archive_start的問題。
Deprecated system parameters with specified values:
log_archive_start
End of deprecated system parameter listing
此時執行下面SQL語句，即可解決這個問題。
SQL> alter system reset log_archive_start scope=spfile sid='*';
System altered.
