在 Oracle 10g 中，以前熟悉的一些参数已经 deprecated 了，有的时候很烦人。
SQL> STARTUP;

// *Cause: One or more obsolete and/or parameters were specified in

告诉我们去 alert log 中查看信息。查找...
Deprecated system parameters with specified values:
log_archive_start
End of deprecated system parameter listing
oops ，10g 不支持该参数了? 原来在 10g 中，当打开归档模式(archive log mode) ，则 ARCH 进程被隐性的自动设定。10g 中也就不会出现 9i 以前那种数据库已经在归档模式，但是自动归档没有被设定的情况了。这也算是 Oracle 修正的一个小Bug。如果是从 9i 升级到 10g 的话，不注意可能会有点小问题的。要解决该问题，需要重置 log_archive_start 参数。
SQL>ALTER SYSTEM RESET log_archive_start SCOPE=SPFILE SID='*';

It's OK now. 查看一下 10g 中都有那些参数是 deprecated 的:
SQL> SELECT NAME, description
2 FROM v$parameter
3 WHERE isdeprecated = 'TRUE';
