TR-4990 ：快速恢復 Oracle VLDB 並在無

04/03/2024 貢獻者

NetApp公司的Alleno Cao、Niyazz Mohamed

目的

使用 Oracle Recovery Manager （ RMAN ）備份工具在 Oracle 中恢復一個非常大的資料庫（ VLDB ）可能是一項非常艱鉅的工作。如果發生故障、備份媒體的資料庫還原程序可能會耗費時間、延遲資料庫恢復、並可能嚴重影響您的服務層級協議（ SLA ）。不過、從第 10g 版開始、 Oracle 推出 RMAN 功能、可讓使用者在 DB 伺服器主機上的其他磁碟儲存設備上、建立 Oracle 資料庫資料檔案的分段映像複本。這些映像複本可以每天使用 RMAN 遞增更新。發生故障時、資料庫管理員（ DBA ）可以迅速將 Oracle 資料庫從故障媒體切換至映像複本、不再需要完整的資料庫媒體還原。結果是 SLA 大幅改善、但成本卻是所需的資料庫儲存設備加倍。

如果您熱衷於 VLDB 的 SLA 、並考慮將 Oracle 資料庫移轉至公有雲（例如 Azure ）、您可以使用 Microsoft Azure NetApp Files （ anf ）等資源來設定類似的資料庫保護結構、以進行備用資料庫映像複本的暫存。在本文件中、我們將示範如何從儲存容量集區中佈建及匯出 NFS 檔案系統、以安裝在 Oracle 資料庫伺服器上、以便在發生主要儲存設備故障時、執行備用資料庫複本以快速恢復。

本解決方案可解決下列使用案例：

Oracle VLDB 映像複本透過 RMAN 遞增合併、位於 Microsoft anf 容量集區儲存設備的 NFS 裝載點上。
在同一 Azure 資料庫伺服器 VM 發生故障時、快速恢復 Oracle VLDB 。
在備用 Azure 資料庫伺服器 VM 發生故障時、快速恢復 Oracle VLDB 。

目標對象

本解決方案適用於下列人員：

在 Azure 中透過 RMAN 設定 Oracle VLDB 映像複本遞增合併的 DBA 、可加快資料庫恢復速度。
在 Azure 公有雲中測試 Oracle 工作負載的資料庫解決方案架構設計師。
管理部署至容量集區儲存設備的 Oracle 資料庫的儲存管理員。
想要在 Azure 雲端環境中備份 Oracle 資料庫的應用程式擁有者。

解決方案測試與驗證環境

此解決方案的測試與驗證是在 Microsoft anf 容量集區儲存設備和 Azure VM 運算環境中執行、可能與最終部署環境不符。如需詳細資訊、請參閱一節 [Key Factors for Deployment Consideration]。

部署考量的關鍵因素

* 用於 RMAN 遞增合併的 Oracle VLDB 儲存配置。 * 在我們的測試與驗證中、用於 Oracle 遞增備份與合併的 NFS 磁碟區是從單一 anf 容量集區分配、每個磁碟區有 100 TiB 、總容量上限為 1000 TiB 。針對超過臨界值的部署、可將多個磁碟區和 anf 容量集區與多個 NFS 裝載點平行串聯、以提供更高的容量。
* 使用 RMAN 遞增合併的 Oracle 可恢復性。 * RMAN 遞增備份與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。如果主要資料儲存和 / 或歸檔記錄檔全部遺失、資料可能會遺失。Oracle 資料庫可從 ANF 資料庫備份映像複本還原至最後一次可用的遞增備份。為了將資料遺失降至最低、可在無 NFS 裝載點上設定 Oracle Flash 恢復區域、並將歸檔記錄備份至無 NFS 裝載、以及資料庫映像複本。
* 在無 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設備不同、 Microsoft anf 是一種雲端型正式作業級儲存設備、可提供高層級的效能與儲存效率。一旦 Oracle VLDB 在 ANF NFS 檔案系統上從主要儲存設備切換至映像複本、資料庫效能就能維持在高層級、同時解決主要儲存設備故障。您可以安心地瞭解使用者應用程式體驗不會因為主要儲存設備故障而受到影響。
* Azure 運算執行個體。 * 在這些測試與驗證中、我們使用 Standard_B4ms Azure VM 做為 Oracle 資料庫伺服器。還有其他 Azure VM 可能經過最佳化、更適合資料庫工作負載。您也需要根據實際工作負載需求、適當調整 Azure VM 的大小、以符合 vCPU 數量和 RAM 數量。
* 無容量池服務層級。 * 無容量池提供三種服務層級： Standard 、 Premium 、 Ultra 。依預設、自動 QoS 會套用至容量集區內建立的磁碟區、以限制磁碟區的處理量。磁碟區的處理量可根據容量集區和服務層級的大小來手動調整。
* DNFS 組態。 * DNFS 內建於 Oracle 核心、已知在 Oracle 部署至 NFS 儲存設備時、可大幅提升 Oracle 資料庫效能。DNFS 封裝為 Oracle 二進位檔案、但預設不會開啟。在 NFS 上進行任何 Oracle 資料庫部署時、都應開啟此功能。對於 VLDB 的多個 ANF 容量集區部署、應正確設定通往不同 ANF 容量集區儲存設備的 DNFS 多重路徑。

解決方案部署

假設您已在 Vnet 內的 Azure 雲端環境中部署 Oracle VLDB 。如果您需要 Azure 中 Oracle 部署的協助、請參閱下列技術報告以取得協助。

您的 Oracle VLDB 可以在 ANF 儲存設備上執行、或在 Azure 雲端生態系統中選擇任何其他儲存設備。下節提供逐步部署程序、可將 RMAN 遞增合併設定為 Oracle VLDB 的映像複本、該複本會暫存於 NFS 掛載中的 ANF 儲存設備。

部署的先決條件

Details

部署需要下列先決條件。

Azure 帳戶已設定完成、您的 Azure 帳戶已建立必要的 Azure vnet 和網路區段。
從 Azure 入口網站主控台、您必須部署兩個 Azure VM 執行個體、分別做為主要 Oracle DB 伺服器和選用的備用 DB 伺服器。如需環境設定的詳細資訊、請參閱上一節的架構圖表。另請檢閱 "Azure Virtual Machine 系列" 以取得更多資訊。
從 Azure 入口網站主控台部署 anf 儲存設備、以裝載儲存 Oracle 資料庫待命映像複本的 NFS 磁碟區。如果您不熟悉 anf 的部署、請參閱文件 "快速入門：設定Azure NetApp Files 功能以建立NFS磁碟區" 以取得逐步指示。

請確定您已在 Azure VM 根 Volume 中至少分配 128G 、以便有足夠的空間來存放 Oracle 安裝檔案。

配置及匯出要掛載於主 Oracle VLDB 伺服器上的 NFS 磁碟區

Details

在本節中、我們將透過 Azure 入口網站主控台、從 ANF 容量集區配置 NFS Volume 。如果設定了多個 ANF 容量集區以容納資料庫的大小、請在其他 ANF 容量集區上重複這些程序。

首先、從 Azure 入口網站主控台、瀏覽至用於暫存 Oracle VLDB 映像複本的 anf 容量集區。
從所選容量集區 - database、按一下 Volumes 然後、 Add volume 啟動附加 Volume 工作流程。
填寫 Volume name、 Quota、 Virtual network`和 `Delegated subnet 以移至 Protocol 頁面。
記下檔案路徑、輸入允許的用戶端 CIDR 範圍、然後啟用 Root Access 適用於 Volume 。
視需要新增Volume標記。
檢閱並建立磁碟區。
以具有 Sudo 權限的使用者身分登入主要 Oracle VLDB 伺服器、並掛載從 anf 儲存設備匯出的 NFS 磁碟區。視需要變更為您的 ANF NFS 伺服器 IP 位址和檔案路徑。您可以從 anf Volume 主控台頁面擷取 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
```
將掛載點所有權變更為 Oracle:oisnhall 、視需要變更為您的 Oracle 使用者名稱和主要群組。
```
sudo chown oracle:oinstall /nfsanf
```

在 anf 上設定 Oracle RMAN 遞增合併至影像複本

Details

RMAN 遞增合併會在每個遞增備份 / 合併間隔持續更新整備資料庫資料檔案映像複本。資料庫備份的映像複本將與您執行遞增備份 / 合併的頻率一樣、是最新的。因此、在決定 RMAN 遞增備份與合併的頻率時、請考量資料庫效能、 RTO 和 RPO 目標。

以 Oracle 使用者身分登入主要 Oracle VLDB 伺服器。
在掛載點 /nfsanf 下建立 oracopy 目錄、以儲存 Oracle 資料檔案映像複本和 Oracle Flash 恢復區域的 archlog 目錄。
```
mkdir /nfsanf/oracopy
```
```
mkdir /nfsanf/archlog
```

透過 sqlplus 登入 Oracle 資料庫、啟用區塊變更追蹤功能、以加快遞增備份速度、並將 Oracle Flash 恢復區域變更為目前位於主要儲存設備上的 anf NFS 裝載。這可讓 RMAN 預設控制檔 / spfile 自動備份和歸檔記錄備份到 ANF NFS 掛載進行還原。

sqlplus / as sysdba

在 sqlplus 提示字元中、執行下列命令。

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

建立 RMAN 備份和遞增合併指令碼。指令碼會分配多個通道以進行平行 RMAN 備份與合併。第一次執行會產生初始完整的基礎映像複本。在完整的執行中、它會先清除保留時間以外的過時備份、以保持整備區域的乾淨。然後在合併和備份之前切換目前的記錄檔。在合併之後進行遞增備份、讓資料庫映像複本以一個備份 / 合併週期追蹤目前的資料庫狀態。合併與備份順序可以反轉、以便根據使用者的偏好、更快恢復。RMAN 指令碼可整合至簡單的 Shell 指令碼中、以便從主要 DB 伺服器上的 crontab 執行。請確定已在 RMAN 設定中開啟控制檔自動備份。
```
vi /home/oracle/rman_bkup_merge.cmd

Add following lines:

  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;
}
```

在主 Oracle VLDB 伺服器上、以具有或不含 RMAN 目錄的 Oracle 使用者身分、在本機登入 RMAN 。在本示範中、我們並未連線至 RMAN 目錄。

rman target / nocatalog;

output:

這將完成 Oracle VLDB 待機映像複本備份與合併的設定。

將 Oracle VLDB 切換至映像複本、以快速恢復

Details

如果由於主要儲存問題（例如資料遺失或毀損）而發生故障、資料庫可以快速切換至 anf NFS 掛載上的映像複本、並在不進行資料庫還原的情況下恢復至目前狀態。消除媒體還原可大幅加速 VLDB 的資料庫還原。此使用案例假設 Oracle VLDB DB 伺服器完整無缺、而且資料庫控制檔、歸檔和目前的記錄都可供還原。

以 Oracle 使用者身分登入 Azure 主要 VLDB 伺服器主機、並在切換之前建立測試表。

您可以在 ANF NFS 掛載中長時間執行 Oracle VLDB 、同時維持預期的效能等級。當主要儲存問題解決時、您可以將遞增備份合併程序還原、並將停機時間降到最低、藉此回復到 IT 。

Oracle VLDB 可從映像複本恢復到備用 DB 伺服器

Details

如果主儲存設備和主要 DB 伺服器主機都遺失、則無法從原始伺服器執行還原。不過、在 ANF NFS 檔案系統上提供的 Oracle 資料庫備份映像複本非常實用。您可以使用備份映像複本、將主要資料庫快速恢復至備用 DB 伺服器（如果有）。在本節中、我們將示範此類恢復的逐步程序。

插入一列以測試先前為 Oracle VLDB 所建立的表格、以還原至替代主機驗證。

關閉主要 VLDB 伺服器主機、以模擬儲存設備和 DB 伺服器主機的整體故障。
在具有相同作業系統和版本的備用 DB 伺服器 ora-02 上、作業系統核心應該修補為主要 VLDB 伺服器主機。此外、在備份 DB 伺服器上安裝和設定的 Oracle 版本和修補程式、只有軟體選項。
類似於主 VLDB 伺服器 ora_01 （例如 oratab ）和 Oracle 使用者 .bash_profile 等）來設定 Oracle 環境將這些檔案備份到 anf NFS 掛載點是很好的做法。
然後、在 ANF NFS 檔案系統上的 Oracle 資料庫備份映像複本會掛載到備用 DB 伺服器上進行還原。下列程序將示範程序的詳細資料。

身為 azueruser 、請建立掛載點。
```
sudo mkdir /nfsanf
```
身為 azureuser 、裝載儲存 Oracle VLDB 備份映像複本的 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

[oracle@ora-02 ~]$

以 Oracle 使用者身分、將 Oracle_home 變數設為待機 DB 伺服器 ora-02 上目前的 Oracle 安裝、將 oracle_sID 設為主要 Oracle 執行個體 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
```

身為 Oracle 使用者、請在 $Oracle_home/DBS 目錄中建立通用的 Oracle 初始化檔案、並設定適當的管理目錄。最重要的是、擁有 Oracle flash recovery area 指向主要 Oracle VLDB 伺服器中定義的 anf NFS 裝載路徑。 flash recovery area 組態將在章節中示範 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

使用下列範例項目：

*.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'

如果存在差異、應將上述初始化檔案替換為從主要 Oracle VLDB 伺服器還原的備份初始化檔案。

身為 Oracle 使用者、請啟動 RMAN 、以便在備用 DB 伺服器主機上執行 Oracle 恢復。首先、在中啟動 Oracle 執行個體 nomount 州/省。

若要加快還原速度、請啟用具有 recovery _parallity 參數的平行階段作業、或在資料庫還原的恢復命令中指定平行度： RECOVER DATABASE PARALLEL (DEGREE d INSTANCES DEFAULT);。一般而言、平行度應等於主機上的 CPU 核心數。

結束 RMAN 、以 Oracle 使用者身分透過 sqlplus 登入 Oracle 、以開啟資料庫、並在未完成還原後重設記錄。

其他恢復後工作

- 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.

如此即可完成 Oracle VLDB 資料庫從 ANF NFS 檔案系統上的備份映像複本還原至備用 DB 伺服器主機。
