RAC (雙節點） + 單實例 DATAGUARD 安裝遇到的問題處理

PRIMARY:? RAC 雙節點 ，存儲：ASM
STANDBY: 單實例????????? 存儲： ASM


單實例? 數據庫如果要使用 ASM存儲，也要安裝一個GRID,選項為：
【】為獨立服務器配置ORACLE GRID INFRASTRUCTURE
其它和安裝GRID RAC一致。
安裝時，也要選擇一個VotingDISK。

完成后狀態如下：


[grid@dg1 ~]$ crs_stat -t
Name?????????? Type?????????? Target??? State???? Host???????
------------------------------------------------------------
ora.CRS.dg???? ora....up.type ONLINE??? ONLINE??? dg1????????
ora.DATA.dg??? ora....up.type ONLINE??? ONLINE??? dg1????????
ora....ER.lsnr ora....er.type ONLINE??? ONLINE??? dg1????????
ora....VERY.dg ora....up.type ONLINE??? ONLINE??? dg1????????
ora.asm??????? ora.asm.type?? ONLINE??? ONLINE??? dg1????????
ora.cssd?????? ora.cssd.type? ONLINE??? ONLINE??? dg1????????
ora.diskmon??? ora....on.type OFFLINE?? OFFLINE??????????????
ora.evmd?????? ora.evm.type?? ONLINE??? ONLINE??? dg1????????
ora.ons??????? ora.ons.type?? OFFLINE?? OFFLINE??????????????
[grid@dg1 ~]$


以下是安裝時遇到的問題及解決方法，這里寫出與大家分享，如果有更好的思路及解決方法，也請回貼告之。





1.GRID 安裝
【】為獨立服務器配置ORACLE GRID INFRASTRUCTURE

[grid@dg1 admin]$ crs_stat -t
Name?????????? Type?????????? Target??? State???? Host???????
------------------------------------------------------------
ora.CRS.dg???? ora....up.type ONLINE??? ONLINE??? localhost??
ora.DATA.dg??? ora....up.type ONLINE??? ONLINE??? localhost??
ora....ER.lsnr ora....er.type OFFLINE?? OFFLINE??????????????
ora....VERY.dg ora....up.type ONLINE??? ONLINE??? localhost??
ora.asm??????? ora.asm.type?? ONLINE??? ONLINE??? localhost??
ora.cssd?????? ora.cssd.type? ONLINE??? ONLINE??? localhost??
ora.diskmon??? ora....on.type OFFLINE?? OFFLINE??????????????
ora.evmd?????? ora.evm.type?? ONLINE??? ONLINE??? localhost??
ora.ons??????? ora.ons.type?? OFFLINE?? OFFLINE???

看到HOST 為 localhost。可能是在安裝GRID前，沒有修改HOSTNAME而引起的。
后面在進行數據復制（duplicate）時，既然提示無法找到ASM ，數據復制不過去。


2.重裝后， 少了ASM,如下：

[grid@dg1 ~]$ crs_stat -t
Name?????????? Type?????????? Target??? State???? Host???????
------------------------------------------------------------
ora....ER.lsnr ora....er.type ONLINE??? ONLINE??? dg1????????
ora.cssd?????? ora.cssd.type? ONLINE??? ONLINE??? dg1????????
ora.diskmon??? ora....on.type OFFLINE?? OFFLINE??????????????
ora.evmd?????? ora.evm.type?? ONLINE??? ONLINE??? dg1????????
ora.ons??????? ora.ons.type?? OFFLINE?? OFFLINE??????


懷疑是刪除重裝引起的。后來使用GRID的deinstall 卸載后，再進行安裝，問題解決。




3.RMAN 數據復制（duplicate）時出錯，如下：
開始找不到是什么原因，使用dbca建立一個新庫，沒有問題。說明不是ASM的問題了。
alert_stbdb.log 還有無法打開+DATA 目錄下的文件的錯誤提示。
后來想到可能是RMAN 是在STANDBY 服務器端執行的原因。到PRIMARY服務器端執行，問題沒有了。


RMAN> duplicate target database for standby from active database nofilenamecheck;

4.PRIMARY 服務器端提示 密碼文件錯誤。查看 log文件無法同步到standby 服務器。
想到RAC環境前幾天修改過SYS的密碼，后把RAC1，及RAC2節點，都執行一次修改密碼。
SQL>alter user sys? identified by oracle;

并且把rac1 重新生成密碼文件：

orapwd file=/tmp/orapwracdb1.ora password=oracle force=y ignorecase=y
并把密碼文件拷貝到standby 服務器端，及rac2.
問題解決。
