本解决方案提供了有关快速恢复在Azure NetApp Files容量池上使用NFS挂载部署到Azure VM计算实例的Oracle VLDB的概述和详细信息、以暂存备用数据库副本、该副本将通过RMAN不断进行增量合并。

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。

如果您对VLDB的SLA非常感兴趣、并考虑将Oracle数据库迁移到Azure等公共云、则可以使用Microsoft Azure NetApp Files (ANF)等资源设置类似的数据库保护结构、以便暂存备用数据库映像副本。在本文档中、我们将演示如何从ANF容量池配置和导出NFS文件系统、以便挂载到Oracle数据库服务器上、暂存备用数据库副本、以便在主存储发生故障时快速恢复。

此解决方案可解决以下使用情形：

Oracle VLDB映像副本通过RMAN在Microsoft ANF容量池存储以外的NFS挂载点上进行增量合并。
在同一Azure数据库服务器VM发生故障时快速恢复Oracle VLDB。
在备用Azure数据库服务器VM发生故障时快速恢复Oracle VLDB。

audience

此解决方案适用于以下人员：

在Azure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。
在Azure公共云中测试Oracle工作负载的数据库解决方案架构师。
负责管理部署到ANF容量池存储的Oracle数据库的存储管理员。
希望在Azure云环境中设置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Microsoft ANF容量池存储和Azure VM计算环境中执行的、这些环境可能与最终部署环境不匹配。有关详细信息，请参见一节部署注意事项的关键因素。

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ANF容量池中分配的、该容量池每个卷具有100 TiB的容量限制、总容量限制为1000 TiB。对于超过阈值的部署、可以将多个卷和ANF容量池与多个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ANF数据库备份映像副本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ANF 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ANF NFS挂载。
*在ANF 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、Microsoft ANF是支持云的生产级存储、可提供高级别的性能和存储效率。Oracle VLDB从主存储切换到ANF NFS文件系统上的映像副本后、可以在解决主存储故障的同时保持较高的数据库性能。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。
* Azure计算实例。*在这些测试和验证中、我们使用Standard"标准B4ms Azure VM作为Oracle数据库服务器。还有其他Azure VM可能已经过优化、更适合数据库工作负载。此外、您还需要根据实际工作负载要求、根据vCPU数量和RAM量相应地调整Azure VM的大小。
* ANF容量池服务级别。* ANF容量池提供三种服务级别：标准、高级、超级。默认情况下、自动QoS会对容量池中创建的卷执行适用场景操作、从而限制卷上的吞吐量。可以根据容量池大小和服务级别手动调整卷上的吞吐量。
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的多个ANF容量池部署、应正确配置指向不同ANF容量池存储的DNFS多路径。

解决方案部署

我们假定您已将Oracle VLDB部署在VNet中的Azure云环境中。如果您需要有关在Azure中部署Oracle的帮助、请参阅以下技术报告以获取帮助。

Oracle VLDB可以运行在ANF存储上、也可以运行在Azure云生态系统中的任何其他可选存储上。下一节介绍了为Oracle VLDB的映像副本设置RMAN增量合并的分步部署过程、该副本暂存在ANF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Azure帐户、并且已在Azure帐户中创建必要的Azure vNet和网段。
从Azure门户控制台中、您必须部署两个Azure VM实例、一个用作主Oracle数据库服务器、另一个用作可选备用数据库服务器。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 "Azure虚拟机系列" 有关详细信息 …
从Azure门户控制台中、部署ANF存储以托管用于存储Oracle数据库备用映像副本的NFS卷。如果您不熟悉ANF的部署、请参见文档 "快速入门：设置 Azure NetApp Files 并创建 NFS 卷" 了解分步说明。

确保您已在Azure VM根卷中至少分配128 G、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Oracle主VLDB服务器上的NFS卷

Details

在本节中、我们将介绍通过Azure门户控制台从ANF容量池配置NFS卷。如果设置了多个ANF容量池来容纳数据库的大小、请对其他ANF容量池重复上述过程。

首先、从Azure门户控制台导航到用于暂存Oracle VLDB映像副本的ANF容量池。
从选定容量池- database`下、单击 `Volumes 然后、 Add volume 以启动添加卷工作流。
填写 Volume name， Quota， Virtual network，和 Delegated subnet 移动到 Protocol 页面。
记下文件路径、输入允许的客户端CIDR范围、然后启用 Root Access 卷。
根据需要添加卷标记。
查看并创建卷。
以具有sudo权限的用户身份登录到主Oracle VLDB服务器、然后挂载从ANF存储导出的NFS卷。根据需要更改ANF NFS服务器IP地址和文件路径。可以从ANF卷控制台页面检索ANF NFS服务器IP地址。
```
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
```
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 /nfsanf
```

将Oracle RMAN增量合并设置为ANF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Oracle VLDB服务器。
在挂载点/nfsanf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 /nfsanf/oracopy
```
```
mkdir /nfsanf/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ANF NFS挂载。这样可以将RMAN默认控制文件/spfile自动备份和归档日志备份到ANF 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 '/nfsanf/oracopy/bct_ntap1.ctf'

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

预期输出：

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

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 '/nfsanf/oracopy/%U';
  allocate channel c2 device type disk format '/nfsanf/oracopy/%U';

  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。

rman target / nocatalog;

output:

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

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 VLDB备用映像副本备份和合并的设置完成。

将Oracle VLDB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ANF 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Oracle VLDB数据库服务器完好无损、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Azure主VLDB服务器主机并创建测试表。

您可以在ANF NFS挂载中长时间运行Oracle VLDB、同时保持预期的性能级别。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。

从映像副本到备用数据库服务器的Oracle VLDB恢复

Details

如果发生故障、并且主存储和主数据库服务器主机均丢失、则无法从原始服务器执行恢复。但是、ANF NFS文件系统上提供的Oracle数据库备份映像副本非常方便。您可以使用备份映像副本将主数据库快速恢复到备用数据库服务器(如果有)。在本节中、我们将展示此类恢复的分步过程。

插入一行以测试我们之前为Oracle VLDB还原到备用主机验证创建的表。

关闭主VLDB服务器主机、以模拟存储和数据库服务器主机完全故障。
在操作系统和版本相同的备用数据库服务器ora-02上、应将操作系统内核作为主VLDB服务器主机进行修补。此外、使用纯软件选项在备用数据库服务器上安装和配置了相同版本的Oracle和修补程序。
将Oracle环境配置为类似于主VLDB服务器ora_01、例如oratab和Oracle用户.bash_profile等最好将这些文件备份到ANF NFS挂载点。
然后、将ANF NFS文件系统上的Oracle数据库备份映像副本挂载到备用数据库服务器上进行恢复。以下步骤演示了流程详细信息。

以azueruser身份创建挂载点。
```
sudo mkdir /nfsanf
```
以azureuser身份挂载用于存储Oracle VLDB备份映像副本的NFS卷。
```
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
```

验证ANF NFS挂载点上的Oracle数据库备份映像副本。

[oracle@ora-02 ~]$

作为Oracle用户、将oracle_home变量设置为备用数据库服务器ora-02上的当前Oracle安装、将oracle_sid设置为主Oracle实例SID。在本示例中、此值为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
```

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服务器中定义的ANF NFS挂载路径。 flash recovery area 第节介绍了配置 Setup Oracle RMAN incremental merge to image copy on ANF。将Oracle控制文件设置为ANF NFS文件系统。

vi $ORACLE_HOME/dbs/initNTAP1.ora

包含以下示例条目：

*.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'

如果出现差异、应将上述init文件替换为从主Oracle VLDB服务器还原的备份init文件。

以Oracle用户身份启动RMAN、以便在备用数据库服务器主机上运行Oracle恢复。首先、在中启动Oracle实例 nomount 状态。

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

设置数据库ID。数据库ID可从ANF NFS挂载点上映像副本的Oracle文件名中检索。
```

从自动备份还原控制文件。如果启用了Oracle控制文件和spfile自动备份、则它们会在每个增量备份和合并周期中进行备份。如果有多个副本可用、则会还原最新备份。

RMAN> restore controlfile from autobackup;

将init文件从spfile还原到/tmp文件夹、以便稍后更新参数文件以与主VLDB匹配。

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 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.

这样、Oracle VLDB数据库便可从ANF NFS文件系统上的备份映像副本恢复到备用数据库服务器主机。
