RAC搭建完成以後，在系統層面做了時區改動之後，發現RAC日誌記錄的時候與操作系統時間不一致。
其中包括
AWR生成的時間點
數據庫alert日誌
CRS各種日誌
等等
舉個例子:
kaycsqdb001r:/u01/app/11.2.0/grid/log/kaycsqdb001r$date
Fri Oct 17 11:06:37 CST 2014
<<<這個時間點,開另外一個窗口執行集羣啓動命令
kaycsqdb001r:/u01/app/11.2.0/grid/log/kaycsqdb001r$tail -f al*1r.log <<<監測日誌輸出

可以看到,日誌寫入時間比操作系統時間往近13小時.
這是由於新版本中的一個變化 ，GRID也有屬於自己的時區設置。在安裝過程中，默認值與操作系統的TZ環境變量相同。
microdb01:/u01/app/11.2.0/grid/crs/install$cat s_crsconfig_microdb01_env.txt
TZ=BEIST-8 <<<<<<<<<<<<<<<GRID的時區設置
NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1
RT_GRQ=ON
EXTSHM=OFF
TNS_ADMIN=
ORACLE_BASE=
microdb01:/u01/app/11.2.0/grid/crs/install$grep TZ /etc/environment
TZ=Asia/Shanghai <<<<<<<<<<<<<<<<<<系統的時區設置
microdb01:/u01/app/11.2.0/grid/crs/install$
會發現GRID的時區設置與系統環境變量TZ不同了。
解決方法：
編輯s_crsconfig_microdb01_env.txt設置TZ=Asia/Shanghai，重啓集羣服務即可恢復。
