ORA-01078: failure in processing system parameters
ORA-29701: unable to connect to Cluster Synchronization Service
grid@linux:~> crsctl check css
CRS-4530: Communications failure contacting Cluster Synchronization Services daemon
grid@linux:~> ps -ef |grep cssd
grid 5975 5932 0 14:51 pts/0 00:00:00 grep cssd
果然沒有CSS的服務daemon進程,再看一下HAS(High Availability Service)的狀態
grid@linux:~> crsctl check has
CRS-4638: Oracle High Availability Services is online
grid@linux:~> ps -ef |grep d.bin
grid 4561 1 2 14:35 ? 00:00:28 /oracle/app/grid_home/bin/ohasd.bin reboot
grid 5988 5932 0 14:51 pts/0 00:00:00 grep d.bin
發現HAS的服務確實啓動了的,而ora.cssd和ora.diskmon這2個服務是依賴於HAS維護的
進一步查看各資源的狀態

再看一下ora.cssd和ora.diskmon的屬性
grid@linux:~>
grid@linux:~> crs_stat -p ora.cssd
NAME=ora.cssd
TYPE=ora.cssd.type
ACTION_SCRIPT=
ACTIVE_PLACEMENT=0
AUTO_START=never
CHECK_INTERVAL=30
DESCRIPTION="Resource type for CSSD"
FAILOVER_DELAY=0
FAILURE_INTERVAL=3
FAILURE_THRESHOLD=5
HOSTING_MEMBERS=
PLACEMENT=balanced
RESTART_ATTEMPTS=5
SCRIPT_TIMEOUT=600
START_TIMEOUT=600
STOP_TIMEOUT=900
UPTIME_THRESHOLD=1m
grid@linux:~> crs_stat -p ora.diskmon
NAME=ora.diskmon
TYPE=ora.diskmon.type
ACTION_SCRIPT=
ACTIVE_PLACEMENT=0
AUTO_START=never
CHECK_INTERVAL=20
DESCRIPTION="Resource type for Diskmon"
FAILOVER_DELAY=0
FAILURE_INTERVAL=3
FAILURE_THRESHOLD=5
HOSTING_MEMBERS=
PLACEMENT=balanced
RESTART_ATTEMPTS=10
SCRIPT_TIMEOUT=60
START_TIMEOUT=60
STOP_TIMEOUT=60
UPTIME_THRESHOLD=5s
到這裏基本就找到了原因了,可以看到這兩個資源的AUTO_START屬性默認都設置爲never,也就是說他們不會隨着HAS服務的啓動而自動啓動的,儘管默認情況下HAS服務是開機自動啓動的.
手工啓動：
grid@linux:~> crsctl start resource ora.cssd
CRS-2672: Attempting to start 'ora.cssd' on 'linux'
CRS-2679: Attempting to clean 'ora.diskmon' on 'linux'
CRS-2681: Clean of 'ora.diskmon' on 'linux' succeeded
CRS-2672: Attempting to start 'ora.diskmon' on 'linux'
CRS-2676: Start of 'ora.diskmon' on 'linux' succeeded
CRS-2676: Start of 'ora.cssd' on 'linux' succeede
、注:ora.cssd和ora.diskmon這兩個服務是有依賴關係的，啓動哪個都會把兩個都起來.、

PS:
1)默認情況下HAS(High Availability Service)是自動啓動的.通過如下命令可以取消和啓用自動啓動
crsctl disable has
crsctl enable has
2)HAS手動啓動和停止
crsctl start has
crsctl stop has
3)查看HAS的狀態
crsctl check has
4)如果想讓ora.css和ora.diskmon服務隨着HAS的啓動而自動啓動，那麼你可以這兩個服務的AUTO_START屬性
crsctl modify resource "ora.cssd" -attr "AUTO_START=1"
or
crsctl modify resource "ora.diskmon" -attr "AUTO_START=1"
5)如果想取消ora.css和ora.diskmon的Auto start
crsctl modify resource "ora.cssd" -attr "AUTO_START=never"
crsctl modify resource "ora.diskmon" -attr "AUTO_START=never"
