rac遷移ocr,votedisk,引數檔案，資料檔案，控制檔案，密碼檔案，redo，undo，temp，asm磁碟
概述：資料庫沒有開啟歸檔，當前環境12.1。votedg（normal）遷移到dg_vote（external），把votedg下的磁碟新增到dg_vote中，並幹掉votedg
因為只建立了votedg磁碟組，cdb，pdb也建立在上面，過程還是比較複雜，因為資料庫很多檔案都放在votedg上，不同的檔案有不同的遷移方式。
遷移目標：
資料檔案，臨時資料檔案，undo，redo，密碼檔案（asm，db），控制檔案（db），引數檔案（asm，db），ocr，votedisk
pdb：資料檔案，臨時資料檔案（因為pdb新建的，直接刪除pdb，減少遷移複雜性）
1.刪除pdb（空pdb，所以先刪了，PDB$SEED得保留）：
SQL> show pdbs
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 PDB MOUNTED
4 PDB1 MOUNTED
alter pluggable database PDB unplug into '/home/oracle/PDB.xml';
drop pluggable database PDB including datafiles;
alter pluggable database PDB1 unplug into '/home/oracle/PDB1.xml';
drop pluggable database PDB1 including datafiles;
SQL> sho pdbs
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
2.asmdisk遷移

格式化磁碟

建立磁碟組 DG_VOTE
create diskgroup DG_VOTE external redundancy disk '/dev/asmvote06';
檢查各節點asm資訊是否一致

startup啟動一個單例項，正常啟動，叢集命令啟動資料庫報錯。
應該是ora.stu12c.db資源有問題
[[email protected] ~]$ srvctl start database -d stu12c

重建db資源(oracle使用者）
srvctl remove database -d stu12c
srvctl add instance -d stu12c -i stu12c1 -oraclehome /oracle/app/oracle/product/12.1/dbhome_1
srvctl add instance -d stu12c -i stu12c1 -node test12c1
srvctl add instance -d stu12c -i stu12c2 -node test12c2
重啟資料庫就ok了
最後別忘了改create引數
