一、找不到磁盘里面的spfile提示$ORACLE_HOME/dbs/下面没有pfile
原因：oracle 和grid安装目录$ORACLE_HOME/bin目录下oracle文件的权限不对
1.chmod +s /u01/app/19.3.0.0/grid/bin/oracle
2.chmod +s /u01/app/oracle/product/19.3.0.0/dbhome_1/bin/oracle
二、dbca找不到已经启动的磁盘组
1、检查oracle和grid账户是否拥有asmdba组
useradd -u 12001 -g oinstall -G asmadmin,asmdba,racdba,asmoper grid
useradd -u 12002 -g oinstall -G dba,backupdba,dgdba,kmdba,asmdba,racdba,asmoper,oper oracle
id oracle
id oracle
uid=12002(oracle) gid=11001(oinstall) groups=11001(oinstall),11002(dba),11003(oper),11004(backupdba),11005(dgdba),11006(kmdba),11007(asmdba),11008(asmoper),11010(racdba)2、oracle 和grid安装目录$ORACLE_HOME/bin目录下oracle文件的权限不对
chmod +s /u01/app/19.3.0.0/grid/bin/oracle
chmod +s /u01/app/oracle/product/19.3.0.0/dbhome_1/bin/oracle
