Oracle 11g RAC中，發現oc4j以及gsd服務都處於offline狀態，這是Oracle 11g RAC預設情形。即便如此，並不影響資料庫的使用，因為 oc4j 是用於WLM 的一個資源, WLM在 11.2.0.2 才可用。GSD則是用於支援dbca,srvctl,oem等的互動工具。本文描述將這兩個服務切換到online。

- 1、環境
- [[email protected] ~]# cat /etc/issue
- Enterprise Linux Enterprise Linux Server release 5.5 (Carthage)
- Kernel \r on an \m
-
- [[email protected] bin]# ./crsctl query crs activeversion
- Oracle Clusterware active version on the cluster is [11.2.0.1.0]
-
- 2、oc4j與所有的gsd處於offline
- [[email protected] ~]$ crs_stat -t | grep OFFLINE
- ora.gsd ora.gsd.type OFFLINE OFFLINE
- ora.linux1.gsd application OFFLINE OFFLINE
- ora.linux2.gsd application OFFLINE OFFLINE
- ora.oc4j ora.oc4j.type OFFLINE OFFLINE
-
- 3、啟動oc4j服務
- #使用srvctl 來啟動oc4j服務
- [[email protected] ~]$ srvctl start oc4j
- OC4J could not be started
- PRCR-1079 : Failed to start resource ora.oc4j
- CRS-2501: Resource ‘ora.oc4j‘ is disabled #提示該服務處於disable狀態
-
- #嘗試使用crsctl來啟動，依然失敗
- [[email protected] ~]$ crsctl start res ora.oc4j -init
- CRS-2613: Could not find resource ‘ora.oc4j‘.
- CRS-4000: Command Start failed, or completed with errors.
-
- #下面先將狀態置為enable狀態
- [[email protected] ~]$ srvctl enable oc4j
- #再次啟動成功
- [[email protected] ~]$ srvctl start oc4j
- [[email protected] ~]$ crs_stat -t | grep oc4j
- ora.oc4j ora.oc4j.type ONLINE ONLINE linux2

- 4、啟動gsd服務
- #查看節點linux1上所有的資源狀態，可以看到輸出的資訊表明GSD也被disable了
- [[email protected] ~]$ srvctl status nodeapps -n linux1
- -n <node_name> option has been deprecated.
- VIP linux1-vip is enabled

-
- #下面查看節點linux2上所有的資源狀態，也可以看到輸出的資訊表明GSD也被disable了
- [[email protected] ~]$ srvctl status nodeapps -n linux2
- -n <node_name> option has been deprecated.
- VIP linux2-vip is enabled

- eONS daemon is running on node: linux2
-
- #將所有的服務置於enable狀態
- [[email protected] ~]$ srvctl enable nodeapps
- PRKO-2415 : VIP is already enabled on node(s): linux1,linux2

- PRKO-2417 : ONS is already enabled on node(s): linux1,linux2
- PRKO-2418 : eONS is already enabled on node(s): linux1,linux2

- 5、關於GSD
- The Global Services Daemon (GSD) runs on each node with one GSD process per node.
- The GSD coordinates with the cluster manager to receive requests from clients such as the DBCA, EM,
- and the SRVCTL utility to execute administrative job tasks such as instance startup or shutdown.
- The GSD is not an Oracle instance background process and is therefore not started with the Oracle instance.
- GSD與rac的管理工具dbca srvctl oem進行互動，用來完成執行個體的啟動關閉等管理工作。
- 為了保證這些管理工具運行正常必須在所有的節點上先啟動 gsd。
- 一個GSD進程支援在一個節點的多個rac.gsd進程，位於$ORACLE_HOME/bin目錄下。
- 其log檔案為$oracle_home /srvm/log/gsdaemon.log。
-
- 例如：
- 假設使用oem工具來啟動一個執行個體，oem把該任務傳遞給相應的智能引擎，該智能引擎產生一個包含SRVCTL命令的指令檔，
- GSD進程讀取該指令檔並且執行該指令碼，最後GSD把執行結果返回給智能引擎,近而智能引擎返回給OEM。
-
- 又例如假設使用srvctl工具關閉所有的執行個體，GSD進程接受來自SRVCTL工具發出的請求，並
- 在本地節點上執行該請求，然後把執行結果返回給SRVCTL會話。
