adg的archive出現gap，使用增量恢復的方式進行恢復adg，RMAN-06094: datafile 1 must be restored
① 主庫丟失歸檔檔案，然後在不重建物理dg的情況下來恢復物理dg

一.4.2.2 模擬歸檔丟失
備庫操作，備庫取消歸檔應用，讓備庫處於只讀模式：
20:43:23 SQL> ALTER ATABASE recover managed standby DATABASE cancel;
資料庫已更改。

主庫配置歸檔2的狀態為defer，目的是為了不把歸檔自動傳遞到備庫,實際情況下往往是由於網路故障，備庫掛掉等等情況導致，我們多次切換主庫日誌：

可以看到，備庫已經斷檔了，157到171都沒有接收，接下來我們刪除主庫的歸檔日誌，我們只刪除54、55這2 個歸檔日誌：
[[email protected] prod]$ rm -rf 1_162_981738248.arc [[email protected] prod]$ rm -rf 1_163_981738248.arc [[email protected] prod]$ rm -rf 1_164_981738248.arc [[email protected] prod]$ rm -rf 1_165_981738248.arc [[email protected] prod]$ rm -rf 1_166_981738248.arc [[email protected] prod]$ rm -rf 1_167_981738248.arc [[email protected] prod]$ rm -rf 1_168_981738248.arc [[email protected] prod]$ rm -rf 1_169_981738248.arc
主庫開啟備庫的歸檔：
SQL> ALTER system SET log_archive_dest_state_2 = 'enable';
備庫開啟日誌恢復模式：
SQL> alter database recover managed standby database using current logfile disconnect from session;
Database altered.
SQL> select thread#,low_sequence#,high_sequence# from v$archive_gap;
THREAD# LOW_SEQUENCE# HIGH_SEQUENCE# ---------- ------------- -------------- 1 162 169
可以看到備庫已經產生gap 了。
一.4.2.3 主庫基於SCN備份
162-169號日誌不見了，這個時候我們以162號的歸檔日誌的next_change#即161號的first_change#為scn號來對主庫基於scn的rman 增量備份。
SQL> SELECT (SELECT MIN(d.CHECKPOINT_CHANGE#) FROM v$datafile d) datafile_scn, (SELECT MIN(d.CHECKPOINT_CHANGE#) FROM v$datafile_header d WHERE rownum = 1) datafile_header_scn, (SELECT current_scn FROM v$database) current_scn, (SELECT b.NEXT_CHANGE# FROM v$archived_log b WHERE b.SEQUENCE# = 161 AND resetlogs_change# = (SELECT d.RESETLOGS_CHANGE# FROM v$database d) AND rownum = 1) NEXT_CHANGE# FROM dual; 2 3 4 5 6
DATAFILE_SCN DATAFILE_HEADER_SCN CURRENT_SCN NEXT_CHANGE# ------------ ------------------- ----------- ------------ 1024825 1024825 1024824
這幾個值基本上差不多，我們可以以 2241214 或者2241213為基準來備份，若是資料檔案和檔案頭的scn 不一致我們應該取這幾個值中最小的一個。
在主庫上進行增量備份：
