oracle 断电起不来，解决方案

首先查看监听，lsnrctl status

发现The listener supports no services

监听没有服务，解决方案：

show parameter service

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
service_names                        string      orcl

手工注册有时能够解决问题：
sys@ORCL> alter system register;
System altered.

sqlplus /nolog 

conn / as sysdba;报错误：ORA-01031: insufficient privileges

查看id

uid=500(oracle) gid=500(oinstall) groups=500(oinstall)

cat $ORACLE_HOME/rdbms/lib/config.c

/*  SS_DBA_GRP defines the UNIX group ID for adminstrative access.  */

/*  Refer to the Installation and User's Guide for further information.  */

  

#define SS_DBA_GRP "oracle"   /* 改成 oinstall */

#define SS_OPER_GRP "oracle"  /* 改成 oinstall */

执行relink all
