1 启动数据库工具有哪些？

SQL*Plus
RMAN
Clund Control
SRVCTL

2 Oracle启动过程

nomount

(1)读取参数文件(spfilexxxxx.ora --> spfile.ora --> initxxxxx.ora --> init.ora )
(2)分配SGA
(3)启动后台进程
(4)打开告警文件和跟踪文件

SQL> startup nomount

RECOMMENDATION:
2021-04-05T14:53:58.745661+08:00
 1. Increase per process memlock (soft) limit to at least 1312MB
 to lock 100% of SHARED GLOBAL AREA (SGA) pages into physical memory

mount

装载数据库就是把数据库文件和实例关联起来，包括以下三个步骤：
(1)oracle根据参数文件 SPFILE 中的参数找到控制文件
(2)打开控制文件
(3)从控制文件获得数据字典和重做日志文件的名字及位置

(1)打开数据库时，实例将打开所有处于联机状态的数据文件和重做日志文件。
(2)在此期间，Oracle 服务器将校验所有的数据文件和联机日志文件能否打开，并对数据库作一致性检查。

控制文件中记录的数据文件头检查点计数 和 数据文件头检查点计数对比，确认是否需要介质恢复。
控制文件中记录的数据文件的结束SCN和数据文件的开始SCN对比，确认是否需要实例恢复。

3 Oracle启动方式有哪几种？

nomount:

startup nomount
srvctl start database -db db_unique_name nomount
srvctl start instance instance_name -d dbname -o nomount

mount:

startup mount
alter database mount;
srvctl start instance instance_name -d dbname -o mount

open:

startup open 
alter database open;
srvctl start instance instance_name -d dbname -o open
srvctl start instance instance_name -d dbname -o open

other:

startup restrict
startup EXCLUSIVE
startup read only
alter database open noresetlogs;
alter database open resetlogs;
alter database open READ ONLY;
startup force(shutdown abort + startup)

接参数文件：

startup pfile='/oracle/dbs/initcjc.ora'
startup spfile='/oracle/dbs/spfilecjc.ora'
srvctl modify database -db db_unique_name -spfile spfile_path

4 Oracle无法启动问题汇总

(1)参数文件损坏故障分析
(2)控制文件损坏故障分析
(3)数据文件损坏故障分析
(4)UNDO文件损坏故障分析
(5)REDO文件损坏故障分析
(6)坏块故障分析
(7)勒索病毒故障分析
(8)更新补丁后数据库异常故障分析
(9)人为误操作故障分析
具体详细内容见下一篇。

5 Oracle无法启动问题定位

(1)启动时查看告警日志
(2)确认启动到哪一步报错的
可以将startup命令拆开执行
startup nomount
alter database mount;
alter database open;
具体详细内容见下一篇。
