情況：
1）從一個有叢集有dg的執行個體—>恢複到單執行個體
2）存儲路徑相同
3）資料量5T左右
1、配置/etc/hosts檔案
.xx.xx sznwk01 //帶庫備份伺服器ip
.xx.xx szcssjk01 //恢複庫ip
.xx.xx szcssjk01_nwk //恢複庫備份ip
.xx.xx sznsapora01_nwk //源庫的備份ip
2、在恢複機運作如下指令查找networker的備份記錄
$ nsrinfo -s sznwk01 -n oracle sznsapora01 |grep ^c|more
c---, date= Mon Apr :: AM CST
cntrl_228610_1_20180423, date= Mon Apr :: AM CST
以下為需要恢複的controlfile:
c---
//這裡我直接選擇了最新的歸檔，沒有認真篩選，直接造成recover database 恢複很久
3、恢複環境部署
從 源端 複制$ORACLE_HOME/dbs/pfile參數檔案到 恢複機 上
vi /oracle/pfile.ora 修改裡面的參數路徑（僅參考）
*.audit_file_dest='/oracle/app/oradba/admin/PMSSC/adump'//路徑要建好
*.audit_sys_operations=TRUE
*.audit_trail='OS'
*.compatible='11.2.0.4.0'
*.control_files='+DG_DATA01/pmssc/controlfile/current.256.880387951' //這個我忘記更改了
*.db_block_size=
*.db_create_file_dest='+DG_DATA01'
*.db_domain=''
*.db_name='PMSSC'
*.diagnostic_dest='/oracle/app'
*.dispatchers=''
*.local_listener=''
*.open_cursors=
*.pga_aggregate_target=
*.processes=
*.resource_limit=TRUE
*.sessions=
*.sga_max_size=
*.sga_target=
*.undo_retention=
*.undo_tablespace='UNDOTBS1'
*.db_files=
4、開啟庫startup nomount pfile=‘路徑’; 5、以下在恢複機上運作
$ rman target /
Recovery Manager: Release .. - Production on Mon Apr ::
Copyright (c) , , Oracle and/or its affiliates. All rights reserved.
connected to target database: PMSSC (not mounted) --->nomount狀态
RMAN>run {
allocate channel t1 type 'sbt_tape';
send 'NSR_ENV=(NSR_SERVER=sznwk01,NSR_CLIENT=sznsapora01_nwk)';
restore controlfile from 'c-2208694315-20180423-04';
release channel t1;
}
RMAN> alter database mount;
RMAN> report schema;
RMAN> run {
allocate channel t1 type 'SBT_TAPE';
allocate channel t2 type 'SBT_TAPE';
send 'NSR_ENV=(NSR_SERVER=sznwk01,NSR_CLIENT=sznsapora01_nwk)';
RESTORE DATABASE;
switch datafile all;
switch tempfile all;
release channel t1;
release channel t2;
}
可以通過這個指令查還有幾個資料檔案在恢複
SQL> select name,bytes/// from v$datafile where bytes=;
no rows selected
//資料量大，從第一天9點半恢複到第二天的晚上八點30分
SQL> select fuzzy, status, error, recover, checkpoint_change#, checkpoint_time, count(*) from v$datafile_header group by fuzzy, status, error, recover, checkpoint_change#, checkpoint_time ;
FUZ STATUS ERROR REC CHECKPOINT_CHANGE# CHECKPOINT_TIME COUNT(*)
--- --------- ----------------------------------------------------------------- --- ------------------ ------------------- ----------
NO ONLINE E+ -- ::
NO ONLINE E+ -- ::
NO ONLINE E+ -- ::
6、建立一個spfile
SQL> create spfile from pfile='/oracle/pfile0926.ora';
File created.
SQL> shutdown immediate
ORA-: database not open
Database dismounted.
ORACLE instance shut down.
SQL> startup mount
ORACLE instance started.
Total System Global Area bytes
Fixed Size bytes
Variable Size bytes
Database Buffers bytes
Redo Buffers bytes
ORA-: error in identifying control file, check alert log for more info
發現控制檔案有問題
回去找/oracle/pfile.ora
*.control_files='+DG_DATA01/pmssc/controlfile/current.256.880387951'
這個控制檔案是源庫恢複過來的那個，沒有進行更改
ASMCMD> cd +DG_DATA01/pmssc/controlfile/
ASMCMD> ls
current
*.control_files='+DG_DATA01/pmssc/controlfile/current.268.974195339'
重新打開試試
[oradba@szcssjk01:/oracle]$ sqlplus / as sysdba
SQL*Plus: Release Production on Tue Apr ::
Copyright (c) , , Oracle. All rights reserved.
Connected to:
Oracle Database g Enterprise Edition Release - bit Production
With the Partitioning, Automatic Storage Management, OLAP, Data Mining
and Real Application Testing options
SQL> shutdown immediate

SQL> startup mount;
ORACLE instance started.
Total System Global Area bytes
Fixed Size bytes
Variable Size bytes
Database Buffers bytes
Redo Buffers bytes
ORA-: error in identifying control file, check alert log for more info
已經是spfile打開了的，是以剛剛改pfile沒起作用，直接改control_files
SQL> show parameter spfile
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
spfile string /home/oradba/app/oradba/produc
t//dbhome_1/dbs/spfilePM
SSC.ora
SQL> show parameter control

control_file_record_keep_time integer
control_files string +DG_DATA01/pmssc/controlfile/c
urrent
control_management_pack_access string DIAGNOSTIC+TUNING
SQL> alter system set control_files='+DG_DATA01/pmssc/controlfile/current.268.974195339';
alter system set control_files='+DG_DATA01/pmssc/controlfile/current.268.974195339'
*
ERROR at line :
ORA-: specified initialization parameter cannot be modified
SQL> alter system set control_files='+DG_DATA01/pmssc/controlfile/current.268.974195339' scope=spfile;
System altered.
SQL> shutdown immediate
ORA-: database not mounted
ORACLE instance shut down.
SQL> startup mount
ORACLE instance started.
Total System Global Area bytes
Fixed Size bytes
Variable Size bytes
Database Buffers bytes
Redo Buffers bytes
Database mounted.
7、配置歸檔路徑
SQL> alter system set log_archive_dest_1='location=/data01/archivelog';
System altered.
SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination /data01/archivelog
Oldest online log sequence
Next log sequence to archive
Current log sequence
8、選擇恢複時間點的思路
查詢備份的時間點
SQL> set linesize pages
SQL> COL STATUS FORMAT a9
SQL> COL hours FORMAT
SQL> col in_size for a15
SQL> col out_sec for a15
SQL> col in_sec for a15
SQL> col out_size for a15
SQL> SELECT SESSION_KEY, INPUT_TYPE, STATUS,
INPUT_BYTES_DISPLAY in_size,
OUTPUT_BYTES_DISPLAY out_size,
COMPRESSION_RATIO,
INPUT_BYTES_PER_SEC_DISPLAY in_sec,
OUTPUT_BYTES_PER_SEC_DISPLAY out_sec,
TO_CHAR(START_TIME,'yyyy-mm-dd hh24:mi') start_time,
TO_CHAR(END_TIME,'yyyy-mm-dd hh24:mi') end_time,
ELAPSED_SECONDS/ hours
FROM V$RMAN_BACKUP_JOB_DETAILS
ORDER BY SESSION_KEY;
SESSION_KEY INPUT_TYPE STATUS IN_SIZE OUT_SIZE COMPRESSION_RATIO IN_SEC OUT_SEC START_TIME END_TIME HOURS

9、進行恢複database

從晚上八點九恢複到淩晨三點多
為什麼恢複這麼久，原因是

恢複的控制檔案是 2018-04-23 08:17:07
恢複的時間點選的是 2018-04-23 08:11:40
恢複的時候是無條件選擇全備的，是以它自動選擇從2018-04-21 06:38開始，因為我們選擇了2018-04-23 08:11:40，中間隔了兩個是增量備份，如果是從21号開始恢複的話，一直恢複下去，恢複完全備還要輪兩個增量備份的歸檔。
