TR-4973 ：在 AWS FSX ONTAP 上使用遞增式合併功能、快速恢復和複製 Oracle VLDB
貢獻者

PDF
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 AWS 等公有雲、您可以使用 AWS FSX ONTAP 等資源來設定類似的資料庫保護結構、以便將備用資料庫映像複本暫存。在本文件中、我們將示範如何從 AWS FSX ONTAP 配置及匯出 NFS 檔案系統、以便安裝在 Oracle 資料庫伺服器上、以便在發生主要儲存設備故障時、暫存備用資料庫複本以進行快速恢復。
更棒的是、我們也說明如何運用 NetApp FlexClone 來建立同一個接移 NFS 檔案系統的複本、以用於其他使用案例、例如使用相同的待命資料庫映像複本來建立開發 / 測試 Oracle 環境、而無需額外的儲存投資。
本解決方案可解決下列使用案例：
-
Oracle VLDB 映像複本透過 NFS 裝載點上的 RMAN 遞增合併、位於 AWS FSX ONTAP 儲存設備之外。
-
在發生故障時、切換至 FSX ONTAP 儲存設備上的資料庫映像複本、快速恢復 Oracle VLDB 。
-
複製儲存 Oracle VLDB 映像複本的 FSX ONTAP NFS 檔案系統磁碟區、以用於備份其他資料庫執行個體、以供其他使用案例使用。
目標對象
本解決方案適用於下列人員：
-
在 AWS 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。
-

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 FSX 檔案系統配置、其處理量為 4Gbps 、原始 SSD IOPS 為 160,000 、容量上限為 192TiB 。針對超過臨界值的部署、可將多個 FSX 檔案系統與多個 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 FSX 資料庫備份映像複本還原至最後一個增量備份。為了將資料遺失降至最低、可在 FSX NFS 掛載點上設定 Oracle Flash 恢復區域、並將歸檔記錄備份至 FSX NFS 掛載及資料庫映像複本。
-
* 在 FSX 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、 AWS FSX ONTAP 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 FSX ONTAP 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的問題。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。
-
* 適用於其他使用案例的 NFS Volume FlexClone Oracle VLDB 映像複本。 * AWS FSX ONTAP FlexClone 提供可寫入的相同 NFS 資料 Volume 的共用複本。因此、即使 Oracle 資料庫已切換、它們仍可用於許多其他使用案例、同時仍能維持整備 Oracle VLDB 影像複本的完整性。如此可大幅減少 VLDB 儲存佔用空間、大幅節省儲存成本。NetApp 建議在資料庫從主要儲存設備切換至資料庫映像複本時、將 FlexClone 活動降至最低、以維持 Oracle 高效能。
-
* EC2 運算執行個體。 * 在這些測試與驗證中、我們使用 AWS EC2 T2.xlge 執行個體做為 Oracle 資料庫運算執行個體。NetApp 建議在正式作業部署中使用 M5 類型 EC2 執行個體作為 Oracle 的運算執行個體、因為它已針對資料庫工作負載最佳化。您必須根據實際工作負載需求、適當調整 EC2 執行個體的 vCPU 數量和 RAM 數量。
-
* FSX儲存HA叢集單一或多區域部署。*在這些測試與驗證中、我們在單一AWS可用性區域中部署了FSXHA叢集。對於正式作業部署、NetApp建議在兩個不同的可用度區域中部署一組FSXHA配對。FSXHA叢集會以HA配對進行配置、並在一對主動-被動檔案系統中進行鏡射同步、以提供儲存層級的備援。多區域部署可在單一 AWS 區域發生故障時、進一步提升高可用度。
-
* FSX 儲存叢集規模。 * 適用於 ONTAP 儲存檔案系統的 Amazon FSX 可提供多達 160,000 個原始 SSD IOPS 、高達 4Gbps 的處理量、以及最高 192TiB 容量。不過、您可以根據部署時的實際需求、根據已配置的 IOPS 、處理量和儲存限制（最低 1,024 GiB ）來調整叢集大小。容量可即時動態調整、而不會影響應用程式可用度。
-
* 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 FSX 檔案系統部署、應正確設定不同 FSX NFS 檔案系統的 DNFS 多重路徑。
解決方案部署
假設您已在 VPC 的 AWS EC2 環境中部署 Oracle VLDB 。如果您需要 AWS 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 FSX ONTAP 或 AWS EC2 生態系統內任何其他選擇儲存設備上執行。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 AWS FSX ONTAP 儲存設備的 NFS 掛載中。
部署的先決條件
Details
部署需要下列先決條件。
-
已設定AWS帳戶、並已在AWS帳戶中建立必要的VPC和網路區段。
-
從 AWS EC2 主控台、您必須部署兩個 EC2 Linux 執行個體、一個做為主要 Oracle DB 伺服器、另一個可選的複製目標 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 "Linux執行個體使用指南" 以取得更多資訊。
-
從 AWS EC2 主控台、部署 Amazon FSX for ONTAP 儲存 HA 叢集、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FSX儲存設備的部署、請參閱文件 "為SfSX. ONTAP 檔案系統建立FSX" 以取得逐步指示。
-
您可以使用下列 Terraform 自動化工具組來執行步驟 2 和 3 、此工具組會建立名為的 EC2 執行個體
ora_01以及名為的 FSX 檔案系統fsx_01。請仔細檢閱指示內容、並在執行前變更變數以符合您的環境。您可以根據自己的部署需求輕鬆修改範本。git clone https://github.com/NetApp-Automation/na_aws_fsx_ec2_deploy.git
|
請確定您已在 EC2 執行個體根磁碟區中至少分配 50g 、以便有足夠的空間來存放 Oracle 安裝檔案。 |
配置及匯出要掛載至 EC2 DB 執行個體主機的 NFS 磁碟區
Details
在本示範中、我們將示範如何透過 SSH 以 fsxadmin 使用者身分透過 FSx 叢集管理 IP 、從命令列登入至 FSx 叢集、以配置 NFS 磁碟區。或者、也可以使用 AWS FSX 主控台來分配磁碟區。如果設定多個 FSX 檔案系統以容納資料庫大小、請在其他 FSX 檔案系統上重複這些程序。
-
首先、透過 CLI 透過 SSH 以 fsxadmin 使用者身分登入 FSX 叢集、以配置 NFS Volume 。變更為您的 FSX 叢集管理 IP 位址、可從 AWS FSX ONTAP UI 主控台擷取。
ssh fsxadmin@172.30.15.53 -
建立與主要儲存設備相同大小的 NFS Volume 、以儲存主要 Oracle VLDB 資料庫資料檔案映像複本。
vol create -volume ora_01_copy -aggregate aggr1 -size 100G -state online -type RW -junction-path /ora_01_copy -snapshot-policy none -tiering-policy snapshot-only -
或者、您也可以從 AWS FSX 主控台 UI 配置磁碟區、並提供下列選項：儲存效率
Enabled、安全風格Unix、 Snapshot 原則None`和儲存分層 `Snapshot Only如下所示。
-
為 Oracle 資料庫建立自訂的快照原則、每日排程及 30 天保留。您應該根據快照頻率和保留時間來調整原則、以符合您的特定需求。
snapshot policy create -policy oracle -enabled true -schedule1 daily -count1 30將原則套用至已佈建的 NFS 磁碟區、以進行 RMAN 遞增備份與合併。
vol modify -volume ora_01_copy -snapshot-policy oracle -
以 EC2 使用者身分登入 EC2 執行個體、並建立目錄 /nfsfsxn 。為其他的 FSX 檔案系統建立額外的掛載點目錄。
sudo mkdir /nfsfsxn -
將 FSX ONTAP NFS 磁碟區裝載至 EC2 DB 執行個體主機。變更為您的 FSX 虛擬伺服器 NFS LIF 位址。NFS LIF 位址可從 FSX ONTAP UI 主控台擷取。
sudo mount 172.30.15.19:/ora_01_copy /nfsfsxn -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 /nfsfsxn
在 FSX 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 DB 伺服器 EC2 執行個體
-
在掛載點 /nfsfsxn 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 /nfsfsxn/oracopymkdir /nfsfsxn/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 FSxN 裝載（如果目前位於主要儲存設備上）。這可讓 RMAN 預設控制檔 / spfile 自動備份和歸檔記錄備份到 FSxN NFS 裝載進行還原。
sqlplus / as sysdba在 sqlplus 提示字元中、執行下列命令。
alter database enable block change tracking using file '/nfsfsxn/oracopy/bct_db1.ctf'alter system set db_recovery_file_dest='/nfsfsxn/archlog/' scope=both; -
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: RUN { allocate channel c1 device type disk format '/nfsfsxn/oracopy/%U'; allocate channel c2 device type disk format '/nfsfsxn/oracopy/%U'; allocate channel c3 device type disk format '/nfsfsxn/oracopy/%U'; allocate channel c4 device type disk format '/nfsfsxn/oracopy/%U'; delete obsolete; sql 'alter system archive log current'; recover copy of database with tag 'OraCopyBKUPonFSxN_level_0'; backup incremental level 1 copies=1 for recover of copy with tag 'OraCopyBKUPonFSxN_level_0' database; } -
在 EC2 DB 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。

這將完成 Oracle 資料庫待命映像複本備份與合併的設定。
將 Oracle DB 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 FSX ONTAP 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。此使用案例假設資料庫主機執行個體完整無缺、而且資料庫控制檔、封存記錄檔和目前記錄檔都可供還原。

以 Oracle 使用者身分登入 EC2 DB 伺服器主機、並在切換之前建立測試表。

您可以在 FSX NFS 掛載中長時間執行 Oracle 資料庫、而不會影響效能、因為 FSX ONTAP 是備援的正式作業級儲存設備、可提供高效能。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 DB 從映像複本還原至不同的 EC2 DB 執行個體主機
Details
當主要儲存設備和 EC2 DB 執行個體主機同時遺失時、無法從原始伺服器執行還原。幸運的是、備援 FSxN NFS 檔案系統上仍有 Oracle 資料庫備份映像複本。您可以快速配置另一個相同的 EC2 DB 執行個體、並透過 NFS 輕鬆將 VLDB 的映像複本掛載到新的 EC2 DB 主機、以執行恢復。在本節中、我們將示範進行此操作的逐步程序。

關閉主要 EC2 DB 執行個體主機、以模擬儲存設備和 DB 伺服器主機的整體故障。
-
透過 AWS EC2 主控台、使用相同作業系統和版本的全新 EC2 DB 執行個體主機 ora_02 。使用與主要 EC2 DB 伺服器主機、 Oracle 預先安裝 RPM 相同的修補程式來設定 OS 核心、並將交換空間新增至主機。安裝與主要 EC2 DB 伺服器主機相同的 Oracle 版本和修補程式、只有軟體選項。這些工作可透過下列連結取得的 NetApp 自動化工具套件來自動化。
-
類似於主要 EC2 DB 執行個體主機 ora_01 （例如 oratab 、 oraInst.loc 和 Oracle 使用者 .bash_profile ）來設定 Oracle 環境。將這些檔案備份到 FSxN NFS 裝載點是很好的做法。
-
FSxN NFS 掛載上的 Oracle 資料庫備份映像複本儲存在涵蓋 AWS 可用區域的 FSx 叢集上、以提供備援、高可用度和高效能。NFS 檔案系統可輕鬆掛載至新伺服器、只要連線能力可達。下列程序會將 Oracle VLDB 備份的映像複本掛載到新版本的 EC2 DB 執行個體主機以進行還原。
身為 EC2 使用者、請建立裝載點。
sudo mkdir /nfsfsxn身為 EC2 使用者、裝載儲存 Oracle VLDB 備份映像複本的 NFS 磁碟區。

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 執行個體中定義的 FSxN 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 FSx。將 Oracle 控制檔設定為 FSX ONTAP NFS 檔案系統。vi $ORACLE_HOME/dbs/initdb1.ora使用下列範例項目：

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 FSxN NFS mount to fstab so that the NFS file system will be mounted when EC2 instance host rebooted. As EC2 user, vi /etc/fstab and add following entry: 172.30.15.19:/ora_01_copy /nfsfsxn 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 Oracle VLDB 資料庫從 FSxN NFS 檔案系統上的備份映像複本還原至新的 EC2 DB 執行個體主機。
複製 Oracle 待命映像複本以用於其他使用案例
Details
使用 AWS FSX ONTAP 進行 Oracle VLDB 映像複本的另一個優點是、它可以透過 FlexClould 、以最少的額外儲存投資來滿足許多其他用途。在下列使用案例中、我們示範如何在 FSX ONTAP 上為其他 Oracle 使用案例（例如開發、 UAT 等）建立快照並複製暫存 NFS 磁碟區
