Test Case:: 12C ASMCMD New feature (Doc ID 1589249.1)
APPLIES TO:
Oracle Database - Enterprise Edition - Version 12.1.0.1 and later
Information in this document applies to any platform.
PURPOSE
There are a few new features at asmcmd level that have been added to make administrative work easier. 在asmcmd级别上添加了一些新功能，以简化管理工作
DETAILS
$$ ASM password file move (PWMOVE)::----------- ASM密码文件移动
========================================
You can move ASM password file online in a running cluster in asmcmd using pwmove command. 您可以使用pwmove命令在asmcmd中的正在运行的群集中在线移动ASM密码文件
Initially, the ASM password file was placed on a CRS diskgroup 最初，ASM密码文件放置在CRS磁盘组上
$ crsctl stat res ora.asm -p|grep PWFILE
PWFILE=+CRS/asm/password/orapwasm
And cluster is up and running .
[oracle@ariidc1 archive]$crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
Move the ASM password file online using ASMCMD 使用ASMCMD在线移动ASM密码文件
$ asmcmd
ASMCMD> pwmove --asm +CRS/asm/password/orapwasm +data/orapwasm
moving +CRS/asm/password/orapwasm -> +data/orapwasm
ASMCMD> exit
Validated Cluster is up and running
[oracle@ariidc1 archive]$ crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
Validated new location of ASM password file. 验证了ASM密码文件的新位置
[oracle@ariidc1 archive]$ crsctl stat res ora.asm -p|grep PWFILE
PWFILE=+data/orapwasm
$$Rebalance monitoring (lsop) from ASMCMD ::-------- 来自ASMCMD的$$重新平衡监视
====================================================================
You can run rebalance for any mounted diskgroup from asmcmd using rebal command . 您可以使用rebal命令从asmcmd运行任何已装入磁盘组的重新平衡。
Not only that,you can monitor rebalance process for that diskgroup from asmcmd using lsop command . 不仅如此，还可以使用lsop命令从asmcmd监视该磁盘组的重新平衡过程。
This is same as v$asm_operation view output from asm sqlplus. 这与asm sqlplus的v$asm_operation视图输出相同
example,
[oracle@ariidc1 archive]$ asmcmd
ASMCMD> lsop
Group_Name Pass State Power EST_WORK EST_RATE EST_TIME
ASMCMD> rebal data01
Rebal on progress.
ASMCMD> lsop
Group_Name Pass State Power EST_WORK EST_RATE EST_TIME
DATA01 RESYNC EST 1 0 0 0
DATA01 COMPACT WAIT 1 0 0 0
DATA01 REBALANCE WAIT 1 0 0 0
ASMCMD> lsop
Group_Name Pass State Power EST_WORK EST_RATE EST_TIME
ASMCMD> exit
[oracle@ariidc1 archive]$ exit
$$ Connect to any ASM instance from any node ::-------- 从任何节点连接到任何ASM实例
=========================================================
In 12C ,using ASMCMD you can connect to another ASM instance and run all kind of supported command on ASM diskgroup of other instance.
在12C中，您可以使用ASMCMD连接到另一个ASM实例，并在另一个实例的ASM磁盘组上运行所有受支持的命令。
Connected to node 2 and from that node ,we logged in ASMCMD . 连接到节点2并从该节点开始，我们登录了ASMCMD
[oracle@ariidc121 archive]$ asmcmd --inst +ASM1
ASMCMD> rebal acfs
Rebal on progress.
ASMCMD> lsop
Group_Name Pass State Power EST_WORK EST_RATE EST_TIME
ACFS COMPACT WAIT 1 0 0 0
ACFS REBALANCE RUN 1 1 0 0
ASMCMD> lsop
Group_Name Pass State Power EST_WORK EST_RATE EST_TIME
ACFS COMPACT RUN 1 0 0 0
ACFS REBALANCE DONE 1 1 0 0
ASMCMD> lsop
Group_Name Pass State Power EST_WORK EST_RATE EST_TIME

$$ Grid related information listing::--------- Grid相关信息列表
============================================
One can use below few asmcmd command to understand , 可以用下面的几个asmcmd命令来了解
1. state of the cluster
ASMCMD> show clusterstate
Normal
2. Mode of the cluster
ASMCMD> showclustermode
ASM cluster : Flex mode enabled
3. Version of the cluster
ASMCMD> showversion
ASM version : 12.1.0.1.0
4. Patches of the grid_home . grid_home的补丁
Here in testing environment ,no patches are applied .
So,listed no patches.
