    SQL> startup
    ORA-01078: failure in processing system parameters
    ORA-29701: unable to connect to Cluster Synchronization Service
    SQL> 

    無法連線到CSS服務上.到作業系統上檢查一下看看

    [grid@vm11gr2] /home/grid> crsctl check css
    CRS-4530: Communications failure contacting Cluster Synchronization Services daemon
    [grid@vm11gr2] /home/grid> 
    [grid@vm11gr2] /home/grid> ps -ef|grep cssd
    果然沒有CSS的服務daemon程式,再看一下HAS(High Availability Service)的狀態

    [grid@vm11gr2] /home/grid> crsctl check has
    CRS-4638: Oracle High Availability Services is online

    [grid@vm11gr2] /home/grid> ps -ef|grep d.bin

    grid 5886 1 0 10:06 ? 00:00:01 /u01/app/grid/product/11.2/grid/bin/ohasd.bin reboot
    [grid@vm11gr2] /home/grid> 
    發現HAS的服務確實啟動了的,而ora.cssd和ora.diskmon這2個服務是依賴於HAS維護的.
    

    進一步檢視各資源的狀態
    [grid@vm11gr2] /home/grid> crs_stat -t

    Name                Type                 Target    State Host 
    --------------------------------------------------------------
    ora.FLASH_DATA.dg   ora.diskgroup.type   OFFLINE OFFLINE vm11gr2 
    ora.SYS_DATA.dg     ora.diskgroup.type   OFFLINE OFFLINE vm11gr2 
    ora.asm             ora.asm.type         OFFLINE OFFLINE vm11gr2 
    ora.cssd            ora.cssd.type        OFFLINE OFFLINE vm11gr2 
    ora.diskmon         ora.diskmon.type     OFFLINE OFFLINE vm11gr2 
    [grid@vm11gr2] /home/grid> 
    
    [grid@vm11gr2] /home/grid> crsctl status resource -t

    ora.SYS_DATA.dg   

                      OFFLINE          OFFLINE     vm11gr2 
    ora.asm           

                      OFFLINE          OFFLINE     vm11gr2

    ora.cssd

    ora.diskmon      

            1         OFFLINE          OFFLINE 

    再看一下ora.cssd和ora.diskmon的屬性
    [grid@vm11gr2] /home/grid> 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@vm11gr2] /home/grid> 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
    [grid@vm11gr2] /home/grid> 
    到這裡基本就找到了原因了,可以看到這兩個資源的AUTO_START屬性預設都設定為never,也就是說他們不會隨著HAS服務的啟動而自動啟動的,
儘管預設情況下HAS服務是開機自動啟動的.好了,那我們就手動啟動一下吧:
    [grid@vm11gr2] /home/grid> crsctl start resource ora.cssd

    CRS-2672: Attempting to start 'ora.cssd' on 'vm11gr2'
    CRS-2679: Attempting to clean 'ora.diskmon' on 'vm11gr2'
    CRS-2681: Clean of 'ora.diskmon' on 'vm11gr2' succeeded
    CRS-2672: Attempting to start 'ora.diskmon' on 'vm11gr2'
    CRS-2676: Start of 'ora.diskmon' on 'vm11gr2' succeeded
    CRS-2676: Start of 'ora.cssd' on 'vm11gr2' succeeded
    [grid@vm11gr2] /home/grid> 

    注:ora.cssd和ora.diskmon這兩個服務是有依賴關係的,啟動哪個都會把兩個都起來.

    [grid@vm11gr2] /home/grid> crs_stat -t

    Name                Type                 Target    State Host 
    --------------------------------------------------------------

    ora.SYS_DATA.dg     ora.diskgroup.type   OFFLINE OFFLINE vm11gr2 
    ora.asm             ora.asm.type         OFFLINE OFFLINE vm11gr2 
    ora.cssd            ora.cssd.type        ONLINE  ONLINE  vm11gr2 
    ora.diskmon         ora.diskmon.type     ONLINE  ONLINE  vm11gr2 
    [grid@vm11gr2] /home/grid> 
    CSS服務起來了,重啟動asm instance   

    [grid@vm11gr2] /home/grid> sqlplus "/as sysasm"

    tips

      1)預設情況下HAS(High Availability Service)是自動啟動的.透過如下命令可以取消和啟用自動啟動
        crsctl disable has
        crsctl enable has
      2)HAS手動啟動和停止
        crsctl start has
        crsctl stop has
      3)檢視HAS的狀態
        crsctl check has
      4)如果想讓ora.css和ora.diskmon服務隨著HAS的啟動而自動啟動,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"
