oracle 11g release 2 crsd启动顺序发生了改变

原创 Oracle 作者:LeiDong12 时间:2011-10-26 09:42:25 0 删除 编辑


操作系统:solaris 10
数据库:oracle 11g release 2 rac
存储:asm

在关闭asm实例时,在alert日志中发现如下记录:

SQL> ALTER DISKGROUP ORA_DATA_DG DISMOUNT /* asm agent *//* {1:63323:40455} */
Mon Sep 26 00:45:36 2011
GMON querying group 1 at 14 for pid 18, osid 3829
Mon Sep 26 00:45:36 2011
NOTE: Instance updated compatible.asm to 11.2.0.0.0 for grp 1
Mon Sep 26 00:45:36 2011
ORA-15032: not all alterations performed
ORA-15027: active use of diskgroup "CRS" precludes its dismount
ERROR: ALTER DISKGROUP CRS DISMOUNT /* asm agent *//* {1:63323:40455} */
Mon Sep 26 00:45:36 2011

在启动asm实例时,在alert日志中出现ARNING:

WARNING: failed to online diskgroup resource ora.ORA_SYS_DG.dg (unable to communicate with CRSD/OHASD)

cause:

In contrast to previous version of CRS, 11gR2 ASM does not depend on CRSD anymore;rather ASM starts before CRSD while clusterware is coming up, and stops after CRSD while clusterware is going down.Due to the new startup sequence, ASM can not update diskgroup resource status in CRSD either during clusterware startup or shutdown, thus above message is logged.

解决方法:

The message can be ignored, the status of diskgroup and diskgroup resource will be synchronize by oraagent once clusterware is fully up.

查看磁盘组的状态信息:

grid@dsmdb1$srvctl status diskgroup -g ORA_SYS_DG.dg -a
PRCR-1031 : Resource attribute NAME value ora.ORA_SYS_DG.DG.dg is not valid
grid@dsmdb1$srvctl status diskgroup -g crs.dg -a
PRCR-1031 : Resource attribute NAME value ora.CRS.DG.dg is not valid
grid@dsmdb1$srvctl status diskgroup -g ORA_data_dg -a
Disk Group ORA_data_dg is running on dsmdb2,dsmdb1
Disk Group ORA_data_dg is enabled

To start or sync diskgroup resource:

grid@dsmdb1$ $GRID_HOME/bin/srvctl start diskgroup -g crs.dg
