目的
使用Oracle Recovery Manager (RMAN)备份工具在Oracle中恢复超大型数据库(VLDB)可能是一项极具挑战性的任务。发生故障时从备份介质还原数据库的过程可能会非常耗时、从而会延迟数据库恢复、并可能显著影响服务级别协议(Service Level Agreement、SLA)。但是、从10g开始、Oracle引入了RMAN功能、允许用户在DB服务器主机上的其他磁盘存储上创建Oracle数据库数据文件的暂存映像副本。这些映像副本可以每天使用RMAN进行增量更新。如果发生故障、数据库管理员(Database Administrator、DBA)可以快速将Oracle数据库从故障介质切换到映像副本、而无需进行完整的数据库介质恢复。结果是SLA得到了大幅改进、尽管成本是所需数据库存储的两倍。
如果您热衷于VLDB的SLA、并考虑将Oracle数据库迁移到AWS等公共云、则可以使用AWS FSx ONTAP等资源设置类似的数据库保护结构来暂存备用数据库映像副本。在本文档中、我们将演示如何从AWS FSx ONTAP配置和导出NFS文件系统、以挂载到Oracle数据库服务器上、从而暂存备用数据库副本、以便在主存储发生故障时快速恢复。
更好的是、我们还会介绍如何利用NetApp FlexClone为同一暂存NFS文件系统创建一份副本、以用于其他使用情形、例如使用此备用数据库映像副本建立开发或测试Oracle环境、而无需额外的存储投资。
此解决方案 可解决以下使用情形：
-
通过AWS FSx ONTAP存储上的NFS挂载点上的RMAN执行Oracle VLDB映像副本增量合并。
-
发生故障时、通过切换到FSx ONTAP存储上的数据库映像副本快速恢复Oracle VLDB。
-
克隆FSx ONTAP NFS文件系统卷、用于存储Oracle VLDB映像副本、以便为其他使用情形建立另一个数据库实例。
audience
此解决方案 适用于以下人员：
-
在AWS中通过RMAN设置Oracle VLDB映像副本增量合并以加快数据库恢复的数据库提供商。
-
一名数据库解决方案架构师、负责在AWS公共云中测试Oracle工作负载。
-
负责管理部署到AWS FSx ONTAP存储的Oracle数据库的存储管理员。
-
希望在AWS FSX/EC2环境中设置Oracle数据库的应用程序所有者。
解决方案 测试和验证环境
此解决方案的测试和验证是在AWS FSx ONTAP和EC2环境中执行的、此环境可能与最终部署环境不匹配。有关详细信息，请参见一节 [Key Factors for Deployment Consideration]。

部署注意事项的关键因素
-
*用于RMAN增量合并的Oracle VLDB存储布局。*在我们的测试和验证中、用于Oracle增量备份和合并的NFS卷是从一个FSx文件系统中分配的、该文件系统的吞吐量为4Gbps、原始SSD IOPS为160000、容量限制为192 TiB。对于超过阈值的部署、可以将多个FSx文件系统与多个NFS挂载点并行连接、以提供更高的容量。
-
使用RMAN增量合并的Oracle可恢复性。 RMAN增量备份和合并通常根据RTO和RPO目标以用户定义的频率执行。如果主数据存储和/或归档日志完全丢失、则可能会发生数据丢失。Oracle数据库可以恢复到FSx数据库备份映像副本中提供的最后一次增量备份。为了最大限度地减少数据丢失、可以在FSx NFS挂载点上设置Oracle闪存恢复区域、并将归档日志与数据库映像副本一起备份到FSx NFS挂载。
-
*在FSx NFS文件系统之外运行Oracle VLDB。*与用于数据库备份的其他批量存储不同、AWS FSx ONTAP是一款支持云的生产级存储、可提供高级别的性能和存储效率。一旦Oracle VLDB从主存储切换到FSx ONTAP NFS文件系统上的映像副本、在解决主存储故障的同时、数据库性能可以保持较高水平。您可以放心地知道、主存储故障不会影响用户应用程序体验。
-
适用于其他使用情形的FlexClone NFS卷的Oracle VLDB映像副本。 AWS FSx ONTAP FlexClone可为同一个NFS数据卷提供可写的共享副本。因此、它们可用于许多其他使用情形、同时仍可保持暂存Oracle VLDB映像副本的完整性、即使Oracle数据库已切换也是如此。这样可以大幅减少VLDB存储占用空间、从而显著节省存储成本。NetApp建议在数据库从主存储切换到数据库映像副本时尽量减少FlexClone活动、以便将Oracle性能保持在较高水平。
-
*EC2计算实例。*在这些测试和验证中，我们使用AWS EC2 T2.xlea占用 空间实例作为Oracle数据库计算实例。NetApp建议在生产部署中使用M5类型的EC2实例作为Oracle的计算实例、因为它已针对数据库工作负载进行了优化。您需要根据实际工作负载要求根据vCPU数量和RAM量适当调整EC2实例的大小。
-
* FSX存储HA集群单区域或多区域部署。*在这些测试和验证中、我们在一个AWS可用性区域中部署了一个FSX HA集群。对于生产部署、NetApp建议在两个不同的可用性区域中部署一个FSX HA对。FSX HA集群始终配置在一个HA对中、该HA对在一对主动-被动文件系统中进行同步镜像、以提供存储级别的冗余。多区域部署可在单个AWS区域发生故障时进一步提高高可用性。
-
* FSX存储集群规模估算。*适用于ONTAP 存储文件系统的Amazon FSX可提供高达160、000个原始SSD IOPS、高达4 Gbps吞吐量以及最大192 TiB容量。但是、您可以根据部署时的实际要求、根据已配置的IOPS、吞吐量和存储限制(最小1、024 GiB)来调整集群的大小。可以动态调整容量、而不会影响应用程序可用性。
-
DNFS配置。 DNFS内置在Oracle内核中、众所周知、在将Oracle部署到NFS存储时、它可以显著提高Oracle数据库性能。DNFS打包到Oracle二进制文件中、但默认情况下不启用。对于NFS上的任何Oracle数据库部署、都应启用此功能。对于VLDB的多FSx文件系统部署、应正确配置指向不同FSx NFS文件系统的DNFS多路径。
解决方案 部署
我们假定您已在VPC中的AWS EC2环境中部署Oracle VLDB。如果您需要有关在AWS中部署Oracle的帮助、请参阅以下技术报告以获取帮助。
您的Oracle VLDB可以在FSx ONTAP上运行、也可以在AWS EC2生态系统中的任何其他可选存储上运行。下一节将分步介绍如何设置RMAN增量合并到Oracle VLDB的映像副本、该副本暂存在AWS FSx ONTAP存储的NFS挂载中。
部署的前提条件
Details
部署需要满足以下前提条件。
-
已设置AWS帐户、并已在您的AWS帐户中创建必要的VPC和网段。
-
在AWS EC2控制台中、您必须部署两个EC2 Linux实例、一个用作主Oracle数据库服务器、另一个用作可选的克隆目标数据库服务器。有关环境设置的详细信息、请参见上一节中的架构图。另请查看 "Linux实例用户指南" 有关详细信息 …
-
从AWS EC2控制台中、部署Amazon FSx for ONTAP存储HA集群、以托管用于存储Oracle数据库备用映像副本的NFS卷。如果您不熟悉FSX存储的部署、请参见相关文档 "为ONTAP 文件系统创建FSX" 了解分步说明。
-
可以使用以下Terraform自动化工具包执行步骤2和步骤3、该工具包会创建一个名为的EC2实例
ora_01和名为的FSX文件系统fsx_01。执行前、请仔细阅读该说明并根据您的环境更改变量。您可以根据自己的部署要求轻松修改此模板。git clone https://github.com/NetApp-Automation/na_aws_fsx_ec2_deploy.git
|
确保您已在EC2实例根卷中至少分配50G、以便有足够的空间来暂存Oracle安装文件。 |
配置和导出要挂载到EC2数据库实例主机的NFS卷
Details
在此演示中、我们将展示如何通过命令行配置NFS卷、方法是以fsxadmin用户身份通过FSx集群管理IP以ssh登录到FSx集群。或者、也可以使用AWS FSx控制台分配卷。如果设置了多个FSx文件系统以适应数据库大小、请在其他FSx文件系统上重复上述过程。
-
首先、以fsxadmin用户身份通过SSH登录到FSx集群、通过命令行界面配置NFS卷。更改为FSx集群管理IP地址、此地址可从AWS FSx ONTAP UI控制台检索。
ssh fsxadmin@172.30.15.53 -
创建与主存储大小相同的NFS卷、用于存储主Oracle VLDB数据库数据文件映像副本。
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、也可以从AWS FSx控制台UI中使用以下选项配置此卷：存储效率
Enabled，安全模式Unix、Snapshot策略None`和存储层 `Snapshot Only如下所示。
-
为Oracle数据库创建一个具有每日计划和30天保留期限的自定义快照策略。您应根据快照频率和保留时间窗口的具体需求调整策略。
snapshot policy create -policy oracle -enabled true -schedule1 daily -count1 30将策略应用于配置的NFS卷以进行RMAN增量备份和合并。
vol modify -volume ora_01_copy -snapshot-policy oracle -
以EC2-user身份登录到EC2实例并创建目录/nfsfsxn。为其他FSx文件系统创建其他挂载点目录。
sudo mkdir /nfsfsxn -
将FSx ONTAP NFS卷挂载到EC2数据库实例主机。更改为FSx虚拟服务器NFS lf地址。可以从FSx ONTAP UI控制台检索NFS lf地址。
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 -
将挂载点所有权更改为oracle：oisntall、根据需要更改为Oracle用户名和主组。
sudo chown oracle:oinstall /nfsfsxn
将Oracle RMAN增量合并设置为FSx上的映像副本
Details
RMAN增量合并会在每个增量备份/合并间隔持续更新暂存数据库数据文件映像副本。数据库备份的映像副本将与您执行增量备份/合并的频率相同。因此、在确定RMAN增量备份和合并的频率时、应考虑数据库性能、RTO和RPO目标。
-
以Oracle用户身份登录到主数据库服务器EC2实例
-
在挂载点/nfsfsxn下创建oracopy目录、用于存储Oracle闪存恢复区域的Oracle数据文件映像副本和归档日志目录。
mkdir /nfsfsxn/oracopymkdir /nfsfsxn/archlog -
通过sqlplus登录到Oracle数据库、启用块更改跟踪以加快增量备份、如果Oracle闪存恢复区域当前位于主存储上、则将其更改为FSxN挂载。这样、RMAN默认控制文件/spfile自动备份和归档日志便可备份到FSxN NFS挂载以进行恢复。
sqlplus / as sysdba从sqlplus提示符处、执行以下命令。
alter database enable block change tracking using file '/nfsfsxn/oracopy/bct_db1.ctf'alter system set db_recovery_file_dest='/nfsfsxn/archlog/' scope=both; -
创建RMAN备份和增量合并脚本。该脚本会为并行RMAN备份和合并分配多个通道。首次执行将生成初始完整基线映像副本。在完整运行中、它会首先清除保留窗口之外的过时备份、以保持暂存区域干净。然后、它会在合并和备份之前切换当前日志文件。增量备份会在合并后进行、以便数据库映像副本会在当前数据库状态后经过一个备份/合并周期。可以反转合并和备份顺序、以便根据用户的偏好加快恢复速度。RMAN脚本可以集成到一个简单的shell脚本中、以便从主数据库服务器上的crontab执行。确保在RMAN设置中打开控制文件自动备份。
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数据库服务器上、以Oracle用户身份本地登录到RMAN、无论是否具有RMAN目录。在此演示中、我们不会连接到RMAN目录。

从RMAN提示符处、执行该脚本。首次执行时创建基线数据库映像副本、后续执行时合并并增量更新基线映像副本。下面介绍了如何执行该脚本以及典型输出。设置通道数、使其与主机上的CPU核匹配。

至此、Oracle数据库备用映像副本备份和合并的设置完成。
将Oracle数据库切换到映像副本、以便快速恢复
Details
如果因主存储问题描述发生故障(例如数据丢失或损坏)、则可以快速将数据库切换到FSx ONTAP NFS挂载上的映像副本、并将其恢复到当前状态、而无需还原数据库。消除介质还原可显著加快VLDB的数据库恢复速度。此使用情形假定数据库主机实例完好无损、并且数据库控制文件、归档日志和当前日志均可用于恢复。
-
在切换之前、以Oracle用户身份登录到EC2数据库服务器主机并创建测试表。

您可以在FSx NFS挂载中长时间运行Oracle数据库、而不会影响性能、因为FSx ONTAP是可提供高性能的冗余生产级存储。修复主存储问题描述后、您可以通过反转增量备份合并过程并将停机时间降至最低来回滚到该主存储LUN。
从映像副本到不同EC2数据库实例主机的Oracle数据库恢复
Details
如果主存储和EC2数据库实例主机均丢失、则无法从原始服务器执行恢复。幸运的是、冗余FSxN NFS文件系统上仍有Oracle数据库备份映像副本。您可以快速配置另一个相同的EC2数据库实例、并通过NFS轻松地将VLDB的映像副本挂载到新的EC2数据库主机中以运行恢复。在本节中、我们将演示执行此操作的分步过程。

关闭主EC2数据库实例主机、以模拟存储和数据库服务器主机的完全故障。
-
通过AWS EC2控制台访问操作系统和版本相同的新EC2数据库实例主机ora_02。使用与主EC2数据库服务器主机相同的修补程序和Oracle预安装RPM配置操作系统内核、并向主机添加交换空间。使用纯软件选项在主EC2数据库服务器主机中安装相同版本和修补程序的Oracle。这些任务可通过以下链接中提供的NetApp自动化工具包自动执行。
-
配置Oracle环境的方式与主EC2数据库实例主机ora_01类似、例如oratab、oraInst.loc和Oracle用户.bash_profile。最好将这些文件备份到FSxN NFS挂载点。
-
FSxN NFS挂载上的Oracle数据库备份映像副本存储在跨越AWS可用性区域的FSx集群上、以实现冗余、高可用性和高性能。只要网络连接可访问、NFS文件系统就可以轻松挂载到新服务器上。以下过程会将Oracle VLDB备份的映像副本挂载到新配置的EC2数据库实例主机以进行恢复。
以EC2用户身份创建挂载点。
sudo mkdir /nfsfsxn以EC2用户身份挂载用于存储Oracle VLDB备份映像副本的NFS卷。

以Oracle用户身份、在$oracle_HOME/dbs目录中创建一个通用Oracle init文件、并配置适当的管理目录。最重要的是、拥有Oracle
flash recovery area指向主Oracle VLDB实例中定义的FSxN NFS挂载路径。flash recovery area第节介绍了配置Setup Oracle RMAN incremental merge to image copy on FSx。将Oracle控制文件设置为FSx ONTAP NFS文件系统。vi $ORACLE_HOME/dbs/initdb1.ora包含以下示例条目：

要加快恢复速度、请使用recovery _parlism参数启用并行会话、或者在恢复命令中指定并行程度以进行数据库恢复： RECOVER DATABASE PARALLEL (DEGREE d INSTANCES DEFAULT);。通常、并行度应等于主机上的CPU核数。 -
退出RMAN、以Oracle用户身份通过sqlplus登录到Oracle、以便在恢复不完整后打开数据库并重置日志。

其他恢复后任务
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.
这样、Oracle VLDB数据库便可从FSxN NFS文件系统上的备份映像副本恢复到新的EC2数据库实例主机。
克隆Oracle备用映像副本、以供其他使用情形使用
Details
使用AWS FSx ONTAP暂存Oracle VLDB映像副本的另一个优势是、可以通过FlexCloned将其用于其他许多用途、而额外的存储投资极少。在以下用例中、我们将演示如何在FSx ONTAP上为其他Oracle用例(如开发、UAT等)创建暂存NFS卷的快照和克隆
-
首先、我们会在之前创建的同一测试表中插入一行。

创建RMAN备份并合并到FSx ONTAP数据库映像副本、以便事务将捕获到FSx NFS挂载上的备份集中、但在恢复克隆的数据库之前不会合并到副本中。
RMAN> @/home/oracle/rman_bkup_merge.cmd
-
以fsxadmin用户身份通过ssh登录到FSx集群、以观察由计划备份策略Oracle创建的快照、并创建一次性快照、以使其包含我们在步骤1中执行的事务。

现在、恢复过程类似于以前在发生故障后恢复到新EC2数据库实例的用例—将Oracle环境(oratab、$oracle_home、$oracle_sid)设置为与主生产实例匹配、 创建一个init文件、其中包含db_recovery文件_dest和db_recovery文件_dest、该文件指向FSx NFS挂载上的闪存恢复目录。然后、通过lanuch RMAN运行恢复。以下是命令步骤和输出。
