在異機實現 Oracle 不完全恢復

otg art set med resetlogs 和數 to_date 數據庫 over 1、將數據庫完全備份集和歸檔日誌備份集傳到執行恢復的 Oracle 服務器
# 傳到中轉服務器
# 傳到中轉服務器
scp -P 2222 database.20181030.5* 218.17.56.50:/tmp/backup
scp -P 2222 archivelog.20181029.5ltgrqir_1_1.rman 218.17.56.50:/tmp/backup
scp -P 2222 archivelog.20181030.* 218.17.56.50:/tmp/backup# 傳到 Oracle 服務器
scp -r backup/ [email protected]:~/2、註冊備份集到控制文件
catalog backuppiece ‘/home/oracle/backup/archivelog.20181029.5ltgrqir_1_1.rman‘; catalog backuppiece ‘/home/oracle/backup/archivelog.20181030.5stguer0_1_1.rman‘; catalog backuppiece ‘/home/oracle/backup/archivelog.20181030.5ttguer0_1_1.rman‘; catalog backuppiece ‘/home/oracle/backup/archivelog.20181030.5utguesp_1_1.rman‘; catalog backuppiece ‘/home/oracle/backup/archivelog.20181030.5vtguesr_1_1.rman‘; catalog backuppiece ‘/home/oracle/backup/archivelog.20181030.60tgueuk_1_1.rman‘; catalog backuppiece ‘/home/oracle/backup/database.20181030.5otgue2k_1_1.rman‘; catalog backuppiece ‘/home/oracle/backup/database.20181030.5ptgue2k_1_1.rman‘; catalog backuppiece ‘/home/oracle/backup/database.20181030.5qtgueid_1_1.rman‘;
3、處理 incarnation (有需要則執行)
shutdown immediate;
startup mount;
list incarnation;
reset database to incarnation 1;4、執行不完全恢復
# rman 腳本
cat restore.rman run { shutdown immediate; startup mount; set until time = "to_date(‘30-10-18 12:00:00‘,‘dd-mm-yy hh24:mi:ss‘)"; restore database; recover database; alter database open resetlogs; } # 恢復 rman target / @restore.rman
註意：如果恢復報錯，檢查備份集 Status 是否為 AVAILABLE。如果備份集有效，仍然無法創建數據文件，則從裝系統和數據庫可解決此問題。
