Purpose

Recovering a Very Large Database (VLDB) in Oracle using the Oracle Recovery Manager (RMAN) backup tool can be a highly challenging task. The database restoration process from backup media in the event of a failure can be time-consuming, delaying the database recovery and potentially impacting your Service Level Agreement (SLA) significantly. However, starting from version 10g, Oracle introduced a RMAN feature that allows users to create staged image copies of the Oracle database data files on additional disk storage located on the DB server host. These image copies can be incrementally updated using RMAN on a daily basis. In the case of a failure, the Database Administrator (DBA) can swiftly switch the Oracle database from the failed media to the image copy, eliminating the need for a complete database media restore. The result is a greatly improved SLA, albeit at the cost of doubling the required database storage.

If you are keen on SLA for your VLDB and contemplating moving the Oracle database to a public cloud such as Azure, you could set up a similar database protection structure using resources such as Microsoft Azure NetApp Files (ANF) for staging your standby database image copy. In this documentation, we demonstrate how to provision and export an NFS file system from ANF capacity pool to be mounted on an Oracle database server for staging a standby database copy for quick recovery in the event of a primary storage failure.

This solution addresses the following use cases:

An Oracle VLDB image copy incremental merge via RMAN on NFS mount point off Microsoft ANF capacity pool storage.
Quick recovery of an Oracle VLDB in the event of a failure on the same Azure database server VM.
Quick recovery of an Oracle VLDB in the event of a failure on a standby Azure database server VM.

Audience

This solution is intended for the following people:

A DBA who sets up Oracle VLDB image copy incremental merge via RMAN in Azure for faster database recovery.
A database solution architect who tests Oracle workloads in the Azure public cloud.
A storage administrator who manages Oracle databases deployed to ANF capacity pool storage.
An application owner who would like to stand up Oracle databases in Azure cloud environment.

Solution test and validation environment

The testing and validation of this solution was performed in a Microsoft ANF capacity pool storage and Azure VM compute environment that might not match the final deployment environment. For more information, see the section [Key Factors for Deployment Consideration].

Key factors for deployment consideration

Oracle VLDB storage layout for RMAN incremental merge. In our tests and validations, the NFS volume for Oracle incremental backup and merge is allocated from a single ANF capacity pool, which has 100 TiB per volume, and 1000 TiB total capacity limit. For deployment over the thresholds, multiple volumes, and ANF capacity pools can be concatenated in parallel with multiple NFS mount points to provide higher capacity.
Oracle recoverability using RMAN incremental merge. The RMAN incremental backup and merge is generally executed at user defined frequency based on your RTO and RPO objectives. If there are total loss of primary data storage and/or archived logs, the data loss can occur. The Oracle database can be recovered up to last incremental backup that is available from ANF database backup image copy. To minimize the data loss, Oracle flash recovery area can be setup on ANF NFS mount point and archived logs are backed up to ANF NFS mount along with database image copy.
Running Oracle VLDB off ANF NFS file system. Unlike other bulk storage for database backup, Microsoft ANF is a cloud enabled production grade storage that delivers high level of performance and storage efficiency. Once Oracle VLDB switches over from primary storage to image copy on ANF NFS file system, database performance can be maintained at high level while the primary storage failure is addressed. You can take comfort to know that user application experience does not suffer as the result of primary storage failure.
Azure compute instances. In these tests and validations, we used Standard_B4ms Azure VMs as the Oracle database servers. There are other Azure VMs that may be optimized and better suited for database workload. You also need to size the Azure VM appropriately for the number of vCPUs and the amount of RAM based on actual workload requirements.
ANF capacity pool service level. ANF capacity pool offers three service level: Standard, Premium, Ultra. By default, an auto QoS applies to a volume created within a capacity pool, which restricts the throughput on the volume. The throughput on a volume can be manually adjusted based on the size of capacity pool and service level.
dNFS configuration. dNFS is built into Oracle kernel and is known to dramatically increase Oracle database performance when Oracle is deployed to NFS storage. dNFS is packaged into Oracle binary but is not turned on by default. It should be turned on for any Oracle database deployment on NFS. For multiple ANF capacity pools deployment for a VLDB, dNFS multi-paths to different ANF capacity pools storage should be properly configured.

Solution deployment

It is assumed that you already have your Oracle VLDB deployed in Azure cloud environment within a VNet. If you need help on Oracle deployment in Azure, please refer to following technical reports for help.

Your Oracle VLDB can be running either on an ANF storage or any other storage of choices within the Azure cloud ecosystem. The following section provides step-by-step deployment procedures for setting up RMAN incremental merge to an image copy of an Oracle VLDB that is staging in an NFS mount off ANF storage.

Prerequisites for deployment

Details

Deployment requires the following prerequisites.

An Azure account has been set up, and the necessary Azure VNet and network segments have been created within your Azure account.
From the Azure portal console, you must deploy two Azure VM instances, one as the primary Oracle DB server and an optional standby DB server. See the architecture diagram in the previous section for more details about the environment setup. Also review the Azure Virtual Machine series for more information.
From the Azure portal console, deploy ANF storage to host the NFS volumes that stores the Oracle database standby image copy. If you are not familiar with the deployment of ANF, see the documentation Quickstart: Set up Azure NetApp Files and create an NFS volume for step-by-step instructions.

Ensure that you have allocated at least 128G in Azure VM root volume in order to have sufficient space to stage Oracle installation files.

Provision and export NFS volume to be mounted on primary Oracle VLDB server

Details

In this section, we show provisioning an NFS volume from an ANF capacity pool via Azure portal console. Repeat the procedures on other ANF capacity pools if more than one ANF capacity pools are set up to accommodate the size of the database.

First, from Azure portal console, navigating to ANF capacity pool that is used to stage Oracle VLDB image copy.
From selected capacity pool - database, click Volumes and then, Add volume to launch add-volume workflow.
Fill in Volume name, Quota, Virtual network, and Delegated subnet to move to Protocol page.
Take a note of the file path, enter allowed clients CIDR range, and enable Root Access for the volume.
Add a volume tag if desired.
Review and create the volume.
Login to primary Oracle VLDB server as a user with sudo privilege and mount the NFS volume exported from ANF storage. Change to your ANF NFS server IP address and file path as necessary. The ANF NFS server IP address can be retrieved from ANF volume console page.
```
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
```
Change mount point ownership to oracle:oisntall, change to your oracle user name and primary group as necessary.
```
sudo chown oracle:oinstall /nfsanf
```

Setup Oracle RMAN incremental merge to image copy on ANF

Details

RMAN incremental merge update the staging database data files image copy continuously at every incremental backup/merge interval. The image copy of database backup will be as up to date as the frequency you execute the incremental backup/merge. So, take into consideration of database performance, your RTO and RPO objectives when deciding the frequency of RMAN incremental backup and merge.

Login to primary Oracle VLDB server as oracle user.
Create an oracopy directory under mount point /nfsanf to store oracle data files image copies and archlog directory for Oracle flash recovery area.
```
mkdir /nfsanf/oracopy
```
```
mkdir /nfsanf/archlog
```

Login to Oracle database via sqlplus, enable block change tracking for faster incremental backup and change Oracle flash recovery area to ANF NFS mount if it is currently on primary storage. This allows the RMAN default control file/spfile autobackup and archived logs to be backed up to ANF NFS mount for recovery.

sqlplus / as sysdba

From sqlplus prompt, execute following command.

alter database enable block change tracking using file '/nfsanf/oracopy/bct_ntap1.ctf'

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

Expected output:

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

Create a RMAN backup and incremental merge script. The script allocates multiple channels for parallel RMAN backup and merge. First execution would generate the initial full baseline image copy. In a complete run, it first purges obsolete backups that are outside of retention window to keep staging area clean. It then switches current log file before merge and backup. The incremental backup follows the merge so that the database image copy is trailing current database state by one backup/merge cycle. The merge and backup order can be reversed for quicker recovery at user's preference. The RMAN script can be integrated into a simple shell script to be executed from crontab on the primary DB server. Ensure control file autobackup is on in RMAN setting.
```
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;
}
```

At the primary Oracle VLDB server, login to RMAN locally as oracle user with or without RMAN catalog. In this demonstration, we are not connecting to a RMAN catalog.

rman target / nocatalog;

output:

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

This completes the setup of an Oracle VLDB standby image copy backup and merge.

Switch Oracle VLDB to image copy for quick recovery

Details

In the event of a failure due to primary storage issue such as data loss or corruption, database can be quickly switched over to image copy on ANF NFS mount and recovered to current state without database restore. Eliminating media restoration speeds up the database recovery tremendously for a VLDB. This use case assumes that the Oracle VLDB DB server is intact and database control file, archived and current logs are all available for recovery.

test oracle incremental merge switch to copy


SQL>

You could run the Oracle VLDB in ANF NFS mount for an extended period of time while maintaining expected performance level. When the primary storage issue is fixed, you can swing back to it by reversing the incremental backup merge processes with minimal downtime.

Oracle VLDB recovery from image copy to a standby DB server

Details

In the event of a failure where both the primary storage and primary DB server host are lost, recovery cannot be performed from the original server. However, your Oracle database backup image copy available on the ANF NFS file system comes in handy. You can quickly recover the primary database to a standby DB server if one is available, using the backup image copy. In this section, we will demonstrate the step-by-step procedures for such recovery.

Insert a row to test table we have created previously for Oracle VLDB restoring to alternative host validation.

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

1 row created.

Shutdown primary VLDB server host to simulate a total failure of storage and DB server host.
On the standby DB server ora-02 with same OS and version, OS kernal should be patched up as primary VLDB server host. Also, the same version and patches of Oracle has been installed and configured on standby DB server with software only option.
Configure oracle environment similiarly to primary VLDB server ora_01, such as oratab, and oracle user .bash_profile etc. It is a good practice to backup those files to ANF NFS mount point.
The Oracle database backup image copy on ANF NFS file system is then mounted on the standby DB server for recovery. The following procedures demonstrate the process details.

As azueruser, create the mount point.
```
sudo mkdir /nfsanf
```
As azureuser, mount the NFS volume that stored Oracle VLDB backup image copy.
```
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
```

Validate the Oracle database backup image copy on ANF NFS mount point.

[oracle@ora-02 ~]$

As oracle user, set ORACLE_HOME variable to current Oracle installation on standby DB server ora-02, ORACLE_SID to primary Oracle instance SID. In this case, it is 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

As oracle user, create a generic Oracle init file in $ORACLE_HOME/dbs directory with proper admin directories configured. Most importantly, have Oracle flash recovery area point to ANF NFS mount path as defined in primary Oracle VLDB server. flash recovery area configuration is demonstrated in section Setup Oracle RMAN incremental merge to image copy on ANF. Set the Oracle control file to ANF NFS file system.

vi $ORACLE_HOME/dbs/initNTAP1.ora

With following example entries:

*.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'

The above init file should be replaced by restored backup init file from primary Oracle VLDB server in the case of discrepancy.

As oracle user, launch RMAN to run Oracle recovery on the standby DB server host. First, start the Oracle instance in nomount state.

RMAN> exit


Recovery Manager complete.

For faster recovery, enable parallel sessions with recovery_parallelism parameter or specify degree of parallel in recovery command for database recovery: RECOVER DATABASE PARALLEL (DEGREE d INSTANCES DEFAULT);. In general, degrees of parallelism should be equal to number of CPU cores on the host.

Exit RMAN, login to Oracle as oracle user via sqlplus to open database and reset log after an incomplete recovery.
