一、环境描述
redhat 7.0
Oracle 12.1.0.2
RAC TO RAC DG
二、报错信息
DGMGRL> add database 'orcldg' as connect identifier is orcldg;
Error: ORA-16571: Oracle Data Guard configuration file creation failure
三、查看官网
Versions 12.1Error: ORA-16571 Oracle Data Guard configuration file creation failure
---------------------------------------------------------------------------Cause: The Oracle Data Guard broker was unable to create the configuration
file on permanent storage.
Action: Verify space, permissions and file name as indicated by the
DG_BROKER_CONFIG_FILE[1|2] initialization parameters and retry the
operation.
检查磁盘空间、权限、文件名，报错日志，发现后台有磁盘报错，检查
99-my-asmdevices.rules文件
KERNEL=="sd*", ENV{DEVTYPE}=="disk", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d $devnode", RESULT=="36000c29db1506865631780672ae94426", RUN+="/bin/sh -c 'mknod /dev/asmdisk1 b $major $minor; chown grid:dba /dev/asmdisk1; chmod 0660 /dev/asmdisk1'"
四、问题解决
权限修改为grid:asmdba,重启集群，解决问题。关于数据库安装的时候创建的用户和组，大家需要有进一步深入的了解才可以，有助于问题的解决。
