Oracle 12c RAC,其中一个节点数据库实例起不来,怎么办

Oracle 12c RAC,其中一个节点数据库实例起不来,怎么办,第1张

两个节点,第一个节点能正常启动,但第二个节点报错。

无论是在集群还是在实例,都无法启动数据库实例。

[grid@m2 ~]$ srvctl start instance -d mdb -i mdb2

PRCR-1064 : 无法在节点 m2 上启动资源 ora.mdb.db

怀疑是虚拟机中的磁盘设置问题,修改虚拟机文件

把 scsi0:1.type="disk"

修改为:

scsi0:1.shared="TRUE"

其它两项不变

scsi0:1.virtualDev = "lsilogic"

scsi0:1.SharedBus="Virtual"

所有共享磁盘修改后为:

scsi0:1.virtualDev = "lsilogic"

scsi0:1.sharedBus = "VIRTUAL"

scsi0:1.shared="TRUE"

disk.locking="FALSE"

========================================================

修改后,再启动实例,还是无法启动,报控制文件出错:

恢复控制文件的同时,可以在其它窗口看到增加的控制文件名称:

后面两个文件是这次恢复的。

修改pfile,添加进去:

*.control_files='+DATA/mdb/controlfile/current.282.821115029','+DATA/mdb/controlfile/current.283.821115539','+RECOVERY/mdb/controlfile/current.269.821031439'

再次使用pfile启动数据库后,建立spfile 文件。

在RAC中,看到数据库没启动起来,再次使用RAC的命令启动一下数据库,完成。

[grid@m1 ~]$ crs_stat -t

对于这个问题,不是一句,两句能说清的。从你叙述的问题来看,能看出你对oracle的框架非常混乱、模糊。

建议你系统的看一下oracle体系结构的内容,英文好,可以直接看官方文档的concept,不好的话可以找一些基础的书籍看

这里,跟你简单说一下oracle的恢复问题

oracle的恢复包括两种:1、实例恢复;2、介质恢复

1、实例恢复:并不需要dba来接入,你只要保证undo、redo完整,oracle能自行完成实例恢复。

2、介质恢复:就是物理文件损坏一类的恢复,或者物理数据的丢失,需要介质恢复。对于介质恢复的方法,需要看你当初是如何进行备份的。

至于日志:分为联机在线日志和归档日志。联机在线日志不可以随便删除。但是都不绝对。

而归档日志也一样,也不能随便删除,但是如果对于恢复数据库有用,那么你就不能删除它

总之,这里三言两语是说不清这个问题的。你想彻底弄明白这样的问题,必须自己把oracle基础的东西掌握了才可以。

oracle 关闭之后启动报错ora-00205是设置错误造成的,解决方法为:

1、工作中遇到在启动数据库实例的时候报错ORA-32004: obsolete or deprecated parameter(s) specified for RDBMS instance。

2、先用静态参数文件pfile启动数据库,发现使用静态参数文件启动时没有报错。

3、利用静态参数文件重建动态参数文件spfile并重启数据库,发现问题已经解决,不再有失效参数错误。

4、查看警报日志 alert_bianxueqing.log  下面是警报的位置。

5、打开文件把文件中的log_archive_start      把这一行直接删除  然后再重启动就可以了。
