Oracle数据库startup mount时的报错处理(ORA

安装监听 Disconnected [oracle@rac1 ~]$ netca Oracle Net Services Configuration:
错误原因：在oracle9i、10g、11g最近几个版本中，数据库默认使用spfile启动数据库，如果spfile不存在，则就会出现上述错误。 解决办法： 查询pfile文件位置，将pfile目录中的init.ora.2182020183512形式的文件copy到$ORACLE_HOME/dbs目录下命名为initorcl.ora即可。 具体操作如下： [grid@rac1 ~]$ su - oracle Password: [oracle@rac1 ~]$ echo $ORACLE_BASE /u01/app/oracle [oracle@rac1 ~]$ find /u01/app/oracle/ -name pfile /u01/app/oracle/admin/RTBRAC/pfile [oracle@rac1 ~]$ cd /u01/app/oracle/admin/RTBRAC/pfile/ [oracle@rac1 pfile]$ ls init.ora.520202320157 [oracle@rac1 pfile]$ echo $ORACLE_HOME /u01/app/oracle/product/11.2.0/db_1 [oracle@rac1 pfile]$ cp init.ora.520202320157 /u01/app/oracle/product/11.2.0/db_1/dbs/initrtbcat1.ora [oracle@rac1 pfile]$再次执行startup 报00845错误 [oracle@rac1 ~]$ sqlplus / as sysdba SQL*Plus: Release 11.2.0.4.0 Production on Tue Jun 20 23:09:22 2023 Copyright (c) 1982, 2013, Oracle.
