Allen Cao、Niyaz Mohamed， NetApp

此解決方案提供了概述和詳細信息，用於快速恢復部署到 Azure VM 計算實例的 Oracle VLDB，並在Azure NetApp Files容量池上安裝 NFS，以暫存透過 RMAN 不斷增量合併的備用資料庫副本。

目的

使用 Oracle 復原管理器 (RMAN) 備份工具還原 Oracle 中的超大型資料庫 (VLDB) 可能是一項極具挑戰性的任務。發生故障時從備份媒體還原資料庫的過程可能非常耗時，從而延遲資料庫復原並可能嚴重影響您的服務等級協定 (SLA)。但是，從 10g 版本開始，Oracle 引入了 RMAN 功能，允許使用者在位於 DB 伺服器主機上的附加磁碟儲存上建立 Oracle 資料庫資料檔案的分階段映像副本。這些影像副本可以使用 RMAN 每天進行增量更新。如果發生故障，資料庫管理員 (DBA) 可以迅速將 Oracle 資料庫從故障媒體切換到映像副本，從而無需進行完整的資料庫媒體還原。儘管所需的資料庫儲存量增加了一倍，但其結果是 SLA 得到了極大改善。

如果您熱衷於 VLDB 的 SLA 並考慮將 Oracle 資料庫遷移到 Azure 等公有雲，則可以使用 Microsoft Azure NetApp Files (ANF) 等資源設定類似的資料庫保護結構來暫存備用資料庫映像副本。在本文檔中，我們示範如何從 ANF 容量池中配置和匯出 NFS 檔案系統，並將其安裝在 Oracle 資料庫伺服器上，以便在主儲存發生故障時暫存備用資料庫副本以便快速復原。

此解決方案適用於以下用例：

  • Oracle VLDB 映像副本透過 RMAN 在 Microsoft ANF 容量池儲存的 NFS 掛載點上進行增量合併。

  • 當同一 Azure 資料庫伺服器 VM 發生故障時，快速復原 Oracle VLDB。

  • 當備用 Azure 資料庫伺服器 VM 發生故障時，快速復原 Oracle VLDB。

對象

此解決方案適用於以下人群：

  • 一位 DBA 透過 Azure 中的 RMAN 設定 Oracle VLDB 映像複製增量合併，以便更快復原資料庫。

  • 在 Azure 公有雲中測試 Oracle 工作負載的資料庫解決方案架構師。

  • 管理部署到 ANF 容量池儲存的 Oracle 資料庫的儲存管理員。

  • 希望在 Azure 雲端環境中建立 Oracle 資料庫的應用程式擁有者。

解決方案測試和驗證環境

此解決方案的測試和驗證是在 Microsoft ANF 容量池儲存和 Azure VM 運算環境中進行的，該環境可能與最終部署環境不符。有關更多信息，請參閱部署考慮的關鍵因素 。

部署考慮的關鍵因素

  • *用於 RMAN 增量合併的 Oracle VLDB 儲存佈局。 *在我們的測試和驗證中，Oracle 增量備份和合併的 NFS 磁碟區是從單一 ANF 容量池分配的，每個磁碟區有 100 TiB，總容量限制為 1000 TiB。對於超過閾值的部署，可以將多個磁碟區和 ANF 容量池與多個 NFS 掛載點並行連接以提供更高的容量。

  • *使用 RMAN 增量合併實作 Oracle 可恢復性。 * RMAN 增量備份和合併通常會根據您的 RTO 和 RPO 目標以使用者定義的頻率執行。如果主資料儲存和/或歸檔日誌完全遺失，則可能會發生資料遺失。 Oracle 資料庫可以還原到 ANF 資料庫備份映像副本提供的最後一個增量備份。為了盡量減少資料遺失，可以在 ANF NFS 安裝點上設定 Oracle 閃回復原區，並將存檔日誌與資料庫映像副本一起備份到 ANF NFS 安裝點。

  • *在 ANF NFS 檔案系統上執行 Oracle VLDB。 *與其他用於資料庫備份的大量儲存不同，Microsoft ANF 是一種支援雲端的生產級存儲，可提供高水準的效能和儲存效率。一旦 Oracle VLDB 從主儲存切換到 ANF NFS 檔案系統上的映像副本，資料庫效能就可以保持在高水平，同時解決主儲存故障。您可以放心，用戶應用程式體驗不會因主儲存故障而受到影響。

  • Azure 計算執行個體。在這些測試和驗證中，我們使用 Standard_B4ms Azure VM 作為 Oracle 資料庫伺服器。其他 Azure VM 可能經過最佳化，更適合資料庫工作負載。您還需要根據實際工作負載需求，適當調整 Azure VM 的 vCPU 數量和 RAM 容量。

  • *ANF 容量池服務等級。 * ANF 容量池提供三種服務等級：標準、進階、超級。預設情況下，自動 QoS 適用於容量池內建立的捲，這會限製卷的吞吐量。可根據容量池的大小和服務等級手動調整磁碟區上的吞吐量。

  • *dNFS 配置。 * dNFS 內建於 Oracle 核心中，並且已知當 Oracle 部署到 NFS 儲存時可顯著提高 Oracle 資料庫效能。 dNFS 打包到 Oracle 二進位檔案中，但預設未開啟。對於 NFS 上的任何 Oracle 資料庫部署，都應該啟用它。對於 VLDB 的多個 ANF 容量池部署，應正確配置到不同 ANF 容量池儲存的 dNFS 多路徑。

解決方案部署

假設您已經在 VNet 內的 Azure 雲端環境中部署了 Oracle VLDB。如果您需要在 Azure 中部署 Oracle 的協助，請參閱下列技術報告以取得協助。

您的 Oracle VLDB 可以在 ANF 儲存體或 Azure 雲端生態系統中的任何其他儲存體上執行。以下部分提供了設定 RMAN 增量合併到在 ANF 儲存的 NFS 掛載中暫存的 Oracle VLDB 映像副本的逐步部署程序。

部署先決條件

Details

部署需要以下先決條件。

  1. 已設定 Azure 帳戶，並在您的 Azure 帳戶內建立了必要的 Azure VNet 和網路區段。

  2. 從 Azure 入口網站控制台，您必須部署兩個 Azure VM 執行個體，一個作為主 Oracle DB 伺服器，另一個作為選用的備用 DB 伺服器。有關環境設定的更多詳細信息，請參閱上一節中的架構圖。還請查看"Azure 虛擬機器系列"了解更多。

  3. 從 Azure 入口網站控制台部署 ANF 儲存體來託管儲存 Oracle 資料庫備用映像副本的 NFS 磁碟區。如果您不熟悉 ANF 的部署，請參閱文檔"快速入門：設定Azure NetApp Files並建立 NFS 卷"以獲得逐步說明。

註 確保在 Azure VM 根磁碟區中指派了至少 128G，以便有足夠的空間來暫存 Oracle 安裝檔案。

提供並匯出要安裝在主 Oracle VLDB 伺服器上的 NFS 卷

Details

在本節中，我們將展示如何透過 Azure 入口網站控制台從 ANF 容量池配置 NFS 磁碟區。如果設定了多個 ANF 容量池來適應資料庫的大小，請對其他 ANF 容量池重複這些過程。

  1. 首先，從 Azure 入口網站控制台導覽至用於暫存 Oracle VLDB 映像複製的 ANF 容量池。

    此圖提供了使用 Azure 入口網站控制台的 ANF 磁碟區設定畫面

  2. 從選定的容量池 - database ， 點選 `Volumes`進而， `Add volume`啟動新增磁碟區工作流程。

    此圖提供了使用 Azure 入口網站控制台的 ANF 磁碟區設定畫面

  3. 填寫 Volume name， Quota ， Virtual network ， 和 `Delegated subnet`移至 `Protocol`頁。

    此圖提供了使用 Azure 入口網站控制台的 ANF 磁碟區設定畫面

  4. 記下檔案路徑，輸入允許的客戶端 CIDR 範圍，然後啟用 `Root Access`音量。

    此圖提供了使用 Azure 入口網站控制台的 ANF 磁碟區設定畫面

  5. 如果需要，請新增磁碟區標籤。

    此圖提供了使用 Azure 入口網站控制台的 ANF 磁碟區設定畫面

  6. 審查並創建卷。

    此圖提供了使用 Azure 入口網站控制台的 ANF 磁碟區設定畫面

  7. 以具有 sudo 權限的使用者身分登入主 Oracle VLDB 伺服器並掛載從 ANF 儲存匯出的 NFS 磁碟區。根據需要變更為您的 ANF NFS 伺服器 IP 位址和檔案路徑。可以從 ANF 磁碟區控制台頁面擷取 ANF NFS 伺服器 IP 位址。

    sudo mkdir /nfsanf
    sudo mount 172.30.136.68:/ora-01-u02-copy /nfsanf -o rw,bg,hard,vers=3,proto=tcp,timeo=600,rsize=262144,wsize=262144,nointr

  8. 將掛載點所有權更改為 oracle:oisntall，根據需要更改為您的 oracle 使用者名稱和主要群組。

    sudo chown oracle:oinstall /nfsanf

在 ANF 上設定 Oracle RMAN 增量合併到映像副本

Details

RMAN 增量合併在每個增量備份/合併間隔持續更新暫存資料庫資料檔案映像副本。資料庫備份的映像副本將與您執行增量備份/合併的頻率一樣最新。因此，在決定 RMAN 增量備份和合併的頻率時，請考慮資料庫效能、RTO 和 RPO 目標。

  1. 以 oracle 使用者登入主 Oracle VLDB 伺服器。

  2. 在掛載點 /nfsanf 下建立一個 oracopy 目錄，用於儲存 Oracle 資料檔案映像副本和用於 Oracle 閃回復原區的 archlog 目錄。

    mkdir /nfsanf/oracopy
    mkdir /nfsanf/archlog

  3. 透過 sqlplus 登入 Oracle 資料庫，啟用區塊變更追蹤以加快增量備份速度，並將 Oracle 快閃記憶體復原區變更為 ANF NFS 掛載（如果它目前位於主儲存上）。這允許將 RMAN 預設控製檔/spfile 自動備份和存檔日誌備份到 ANF NFS 掛載以進行還原。

    sqlplus / as sysdba

    在 sqlplus 提示字元下，執行以下命令。

    alter database enable block change tracking using file '/nfsanf/oracopy/bct_ntap1.ctf'
    alter system set db_recovery_file_dest='/nfsanf/archlog/' scope=both;

    預期輸出：

    [oracle@ora-01 ~]$ sqlplus / as sysdba

SQL*Plus: Release 19.0.0.0.0 - Production on Wed Mar 20 16:44:21 2024

Database altered.

SQL> alter system set db_recovery_file_dest='/nfsanf/archlog/' scope=both;

SQL>

  4. 建立 RMAN 備份和增量合併腳本。該腳本為並行 RMAN 備份和合併分配多個通道。第一次執行將產生初始的完整基線影像副本。在完整運行過程中，它首先清除保留視窗之外的過時備份，以保持暫存區清潔。然後它在合併和備份之前切換當前日誌檔案。增量備份在合併之後進行，因此資料庫映像副本落後於目前資料庫狀態備份/合併週期。可以根據使用者的喜好逆轉合併和備份的順序，以便更快地恢復。 RMAN 腳本可以整合到一個簡單的 shell 腳本中，從主 DB 伺服器上的 crontab 執行。確保 RMAN 設定中的控製檔自動備份處於開啟狀態。

    vi /home/oracle/rman_bkup_merge.cmd

Add following lines:

RUN
{
  allocate channel c1 device type disk format '/nfsanf/oracopy/%U';
  allocate channel c2 device type disk format '/nfsanf/oracopy/%U';
  allocate channel c3 device type disk format '/nfsanf/oracopy/%U';
  allocate channel c4 device type disk format '/nfsanf/oracopy/%U';
  delete obsolete;
  sql 'alter system archive log current';
  recover copy of database with tag 'OraCopyBKUPonANF_level_0';
  backup incremental level 1 copies=1 for recover of copy with tag 'OraCopyBKUPonANF_level_0' database;
}

  5. 在主 Oracle VLDB 伺服器上，以 oracle 使用者身分本地登入 RMAN，可以使用或不使用 RMAN 目錄。在此示範中，我們沒有連接到 RMAN 目錄。

    rman target / nocatalog;

output:

[oracle@ora-01 ~]$ rman target / nocatalog

  6. 從 RMAN 提示字元執行腳本。第一次執行會建立基準資料庫映像副本，後續執行則會逐步合併和更新基準映像副本。以下是如何執行腳本以及典型的輸出。設定通道數以符合主機上的 CPU 核心。

    RMAN> @/home/oracle/rman_bkup_merge.cmd

7>   delete obsolete;
8>   sql 'alter system archive log current';
9>   recover copy of database with tag 'OraCopyBKUPonANF_level_0';

這樣就完成了 Oracle VLDB 備用映像副本備份和合併的設定。

將 Oracle VLDB 切換到映像副本以實現快速恢復

Details

如果因主儲存問題（例如資料遺失或損壞）而發生故障，資料庫可以快速切換到 ANF NFS 掛載上的映像副本，並恢復到目前狀態，而無需資料庫還原。消除媒體復原可大幅加快 VLDB 的資料庫復原速度。此用例假設 Oracle VLDB DB 伺服器完好無損，且資料庫控製文件、存檔日誌和目前日誌均可供復原。

  1. 以 oracle 使用者登入 Azure 主 VLDB 伺服器主機，並在切換之前建立測試表。

  7. 您可以在 ANF NFS 掛載中執行 Oracle VLDB 較長時間，同時保持預期的效能水準。當主儲存問題解決後，您可以透過逆轉增量備份合併過程，以最少的停機時間恢復原狀。

Oracle VLDB 從映像複製到備用資料庫伺服器的恢復

Details

如果發生故障，主儲存和主資料庫伺服器主機都會遺失，則無法從原始伺服器進行復原。但是，ANF NFS 檔案系統上提供的 Oracle 資料庫備份映像副本會很方便。您可以使用備份映像副本快速將主資料庫還原到備用資料庫伺服器（如果有）。在本節中，我們將示範此類恢復的逐步過程。

  1. 在我們之前為 Oracle VLDB 還原到備用主機驗證而建立的測試表中插入一行。

    SQL> insert into test values(2, sysdate, 'test recovery on a new Azure VM host with image copy on ANF');

1 row created.

  2. 以 oracle 使用者身分執行 RMAN 增量備份並合併以將交易刷新到 ANF NFS 掛載上的備份集。

RMAN> @rman_bkup_merge.cmd

  3. 關閉主 VLDB 伺服器主機以模擬儲存和 DB 伺服器主機的完全故障。

  4. 在具有相同作業系統和版本的備用資料庫伺服器 ora-02 上，作業系統核心應與主 VLDB 伺服器主機一樣進行修補。此外，已在僅使用軟體選項的備用資料庫伺服器上安裝和設定了相同版本和修補程式的 Oracle。

  5. 配置與主 VLDB 伺服器 ora_01 類似的 oracle 環境，例如 oratab 和 oracle 使用者 .bash_profile 等。將這些檔案備份到 ANF NFS 掛載點是一種很好的做法。

  6. 然後將 ANF NFS 檔案系統上的 Oracle 資料庫備份映像副本安裝在備用 DB 伺服器上以進行還原。以下步驟示範了流程的細節。

    以 azueruser 身分建立掛載點。

    sudo mkdir /nfsanf

    以 azureuser 身分掛載儲存 Oracle VLDB 備份映像副本的 NFS 磁碟區。

    sudo mount 172.30.136.68:/ora-01-u02-copy /nfsanf -o rw,bg,hard,vers=3,proto=tcp,timeo=600,rsize=262144,wsize=262144,nointr

  7. 驗證 ANF NFS 掛載點上的 Oracle 資料庫備份映像副本。

  8. 驗證 ANF NFS 掛載上可用的 Oracle 存檔日誌以進行恢復，並記下最後一個日誌檔案日誌序號。在本例中為 10。我們的恢復點最多到日誌序號 11。

    [oracle@ora-02 ~]$ ls -ltr /nfsanf/archlog/NTAP1/archivelog/2024_03_22

[oracle@ora-02 ~]$

  9. 以 oracle 使用者身份，將 ORACLE_HOME 變數設定為備用 DB 伺服器 ora-02 上的目前 Oracle 安裝，將 ORACLE_SID 設定為主 Oracle 實例 SID。在這種情況下，它是 NTAP1。

    [oracle@ora-02 ~]$ export ORACLE_HOME=/u01/app/oracle/product/19.0.0/NTAP2
[oracle@ora-02 ~]$ export ORACLE_SID=NTAP1
[oracle@ora-02 ~]$ export PATH=$PATH:$ORACLE_HOME/bin

  10. 以 oracle 使用者身份，在 $ORACLE_HOME/dbs 目錄中建立一個通用 Oracle 初始化文件，並配置適當的管理目錄。最重要的是，擁有 Oracle flash recovery area`指向主 Oracle VLDB 伺服器中定義的 ANF NFS 掛載路徑。 `flash recovery area`配置在章節中進行了演示 `Setup Oracle RMAN incremental merge to image copy on ANF。將 Oracle 控制檔設定為 ANF NFS 檔案系統。

    vi $ORACLE_HOME/dbs/initNTAP1.ora

    使用以下範例條目：

    *.audit_file_dest='/u01/app/oracle/admin/NTAP1/adump'
*.audit_trail='db'
*.compatible='19.0.0'
*.control_files=('/nfsanf/oracopy/NTAP1.ctl')
*.db_block_size=8192
*.db_create_file_dest='/nfsanf/oracopy/'
*.db_domain='solutions.netapp.com'
*.db_name='NTAP1'
*.db_recovery_file_dest_size=85899345920
*.db_recovery_file_dest='/nfsanf/archlog/'
*.diagnostic_dest='/u01/app/oracle'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=NTAP1XDB)'
*.enable_pluggable_database=true
*.local_listener='LISTENER'
*.nls_language='AMERICAN'
*.nls_territory='AMERICA'
*.open_cursors=300
*.pga_aggregate_target=1024m
*.processes=320
*.remote_login_passwordfile='EXCLUSIVE'
*.sga_target=10240m
*.undo_tablespace='UNDOTBS1'

    如果出現差異，則應使用從主 Oracle VLDB 伺服器復原的備份初始化檔案取代上述初始化檔案。

  11. 以 oracle 使用者身分啟動 RMAN 在備用資料庫伺服器主機上執行 Oracle 復原。首先，啟動 Oracle 實例 `nomount`狀態。

    [oracle@ora-02 ~]$ rman target / nocatalog

  12. 設定資料庫ID。可以從 ANF NFS 掛載點上的映像副本的 Oracle 檔案名稱中檢索資料庫 ID。

    RMAN> set dbid = 2441823937;

executing command: SET DBID

  13. 從自動備份還原控製檔。如果啟用了 Oracle 控製檔案和 spfile 自動備份，則它們會在每個增量備份和合併週期中備份。如果有多個副本可用，將還原最新的備份。

    RMAN> restore controlfile from autobackup;

output file name=/nfsanf/oracopy/NTAP1.ctl

  14. 將初始化檔案從 spfile 還原到 /tmp 資料夾，以便稍後更新參數檔案以與主 VLDB 相符。

    RMAN> restore spfile to pfile '/tmp/archive/initNTAP1.ora' from autobackup;

  15. 掛載控制檔並驗證資料庫備份映像副本。

    RMAN> alter database mount;

    註 為了更快地恢復，請使用 recovery_parallelism 參數啟用並行會話或在資料庫恢復的恢復命令中指定並行度： RECOVER DATABASE PARALLEL (DEGREE d INSTANCES DEFAULT); 。一般來說，並行度應該等於主機上的 CPU 核心數。

  18. 退出 RMAN，透過 sqlplus 以 oracle 使用者登入 Oracle，以在不完全恢復後開啟資料庫並重設日誌。

  21. 其他恢復後任務

    - Add ANF NFS mount to fstab so that the NFS file system will be mounted when DB server host rebooted.

        As azureuser, sudo vi /etc/fstab and add following entry:

        172.30.136.68:/ora-01-u02-copy       /nfsanf        nfs     rw,bg,hard,vers=3,proto=tcp,timeo=600,rsize=262144,wsize=262144,nointr  0       0

- Update the Oracle init file from primary databse init file backup that is restored to /tmp/archive and create spfile as needed.

這樣就完成了從 ANF NFS 檔案系統上的備份映像副本到備用 DB 伺服器主機的 Oracle VLDB 資料庫復原。
