环境说明：
11.2.0.4 RAC 环境
Centos 7.6系统
虚拟机(磁盘模式独立-持久)
报错说明：
机房断电导致物理机全部down机。当启动服务器后发现asm可正常启动，但是db为运行，于是手动该命令启动后报错，重点观察错误已标红

注：标红提示说该参数文件不在fls目录中存在，于是进入asmcmd中查看，过真spfile不存在
查看asm磁盘中文件
ASMCMD> pwd
+racdata/fls
ASMCMD> ls
ARCH1/
ARCHIVELOG/
CONTROLFILE/
DATAFILE/
ONLINELOG/
TEMPFILE/
spfilefls.ora
此时发现没有报错中的+racdata/FLS/PARAMETERFILE/spfile.259.1143572893这个文件，spfilefls.ora只是在+oradata/fls/spfilefls.ora中，说明spfile目录问题导致，需要手动
说明:实际上在RAC环境中，我们更多时候是用srvctl来管理RAC资源，而srvctl的信息来自ocr，包括spfile的位置信息。我们刚才那样做虽然修改了参数文件的位置，但是ocr并不知道，它还用原来的文件启动数据库。
此时用命令查看，发现spfile文件路径确实没有
[grid@tfls1:/oracle/app/11.2.0/grid/log/tfls1]$srvctl config database -d fls -a
Database unique name: fls
Database name:

更新ocr中spfile路径
PRCD-1163 : Failed to modify database fls
PRCR-1071 : Failed to register or update resource ora.fls.db
CRS-0245: User doesn''t have enough privilege to perform the operation
发现用grid更新竟然报错，没有足够的权限，果断用oracle尝试下
[oracle@tfls1:/home/oracle]$srvctl modify database -d fls -p +racdata/fls/spfilefls.ora
果然没有问题
启动数据库
[oracle@tfls1:/home/oracle]$srvctl modify database -d fls -p +racdata/fls/spfilefls.ora
[grid@tfls1:/home/grid]$crsctl stat res -t
查看都正常，并查看日志没有问题
