OLR

OLR:Oracle Local Registry

环境:11.2.0.3  RAC  RHEL6.5

It contains local node specific configuration required by OHASD and is not shared between nodes;。认为非常重要,准备备份。由于OLR不会自己主动备份,所以准备手动备份。又由于假设.手动备份路径不存在,那么会影响ohasd进程,使其异常。那么,确定手动备份路径是否存在就显得非常重要了。当然,更重要的问题是确认,当前备份的路径是哪个

查看olr备份路径能够通过:

1. ocrconfig -local -showbackup manual
来查看备份位置。从而确认备份文件夹。(为了确认是当前文件夹,能够先运行手工备份)

2. ocrdump -local <olr_dump_name>
more <olr_dump_name> 来查找 [SYSTEM.OLR.BACKUP.LOC] 的相应键值。 

在研究OLR的过程中,还发现,每四个小时,OLR文件的改动时间就会改变,对此,sr给出了解释:

您能够不必操心这样的情况:
在集群执行时,olr是缓存在内存中的。
依据上面的測试,这应该不过将缓存内容刷新至磁盘的一种动作。
