ORA问题，在那里没有回复；无奈之下贴在这里，版主勿见怪；
本人的问题如下：
$ svrmgrl

Oracle Server Manager Release 3.1.5.0.0 - Production

(c) Copyright 1997, Oracle Corporation.  All Rights Reserved.

Oracle8i Release 8.1.5.0.0 - Production
With the Java option
PL/SQL Release 8.1.5.0.0 - Production

SVRMGR>; connect internal
Connected.
SVRMGR>; shutdown immediate
ORA-01012: not logged on
SVRMGR>; startup
ORA-01081: cannot start already-running ORACLE - shut it down first
SVRMGR>; shutdown immediate
ORA-01012: not logged on
SVRMGR>; connect /as sysdba
Connected.
SVRMGR>; shutdown immediate
ORA-01034: ORACLE not available


以上是今天的问题；昨天还不是这样；具体如下：


$ svrmgrl

(c) Copyright 1997, Oracle Corporation. All Rights Reserved.

Oracle8i Release 8.1.5.0.0 - Production

SVRMGR>; connect internal

SVRMGR>; startup

ORA-01506: missing or illegal database name

执行了startup pfile=....../init.ora
出现如下错误：
SVRMGR>; startup pfile=/export/home0/oracle/product/8.1.7/dbs/init.ora
ORACLE instance started.

请高手指教错误；具体配置文件应该没有问题。
如果需要我可以将ETC/SYSTEM，.PROFILE文件内容贴出。
