Deployment Architecture for Resilience and Recovery
When it comes to disaster recovery for Oracle HCM, selecting the appropriate deployment architecture is crucial. This section will discuss active/active and active/standby DR deployment architectures, as well as the many variations that exist within them. Our detailed guide to deployment architecture for resilience and recovery is based on dependable sources and will enable you to make informed decisions for your organization’s disaster recovery plan.
Active/active and active/standby DR deployment architectures
Let’s illustrate the differences between these two architectures in a table, emphasizing their key traits:
|Architecture Type||Key Traits||Cost||Failover Time||RTO/RPO Objectives||Flexibility|
|Active/Active||Faster recovery, utilizes multiple regions/zones to avoid regional failures||High cost due to more resources and investment||No failover necessary||Low RTO/RPO objectives||Less flexibility due to high reliance on resources|
|Active/Standby||High availability at lower cost, variations available||Lower cost compared to active/active architecture||Could take some time for failover||RTO/RPO objectives could be high or low, depending on the specific architecture||More flexibility compared to active/active architecture|
Organizations must pick the right architecture that fits their business needs & budget. Best practice is an active-active environment with different regions/zones to prevent regional failures, and low RTO/RPO objectives. But, this needs significant investment due to similar on-premises resources for each region – which might not align with the org’s budget. So, active-standby might be better based on disaster risk appetite & acceptability of downtime during recovery.
Flexibility matters for active/standby – variations are unique!
Variations in active/standby deployment architectures
An active/standby deployment architecture sets up a primary site with an active app and a standby site ready for failover. Variations of this architecture exist, such as Data Guard Broker, Fast-Start Failover, or Single-instance Oracle databases. Also, Zero Data Loss Recovery Appliance (ZDLRA) can provide full backups.
Pros and cons come with different architectures. Lower RTO, but less resource efficiency. Database synchronization challenges. Interactive selection across sites. It’s important to select the right architecture, based on enterprise needs.
To get high availability, redundancy is needed at hardware, software, and business levels. A directory structure for Oracle Fusion Middleware can help organize files.
Directory Structure Recommendations for Maximum Availability
When it comes to disaster recovery for Oracle HCM Site, having a solid directory structure in place is not crucial for maximum availability. In fact, there is no evidence to suggest that directory structure impacts disaster recovery capabilities. Instead, the key strategies for disaster recovery include redundant binary installations and shared storage. In this section, we will explore the recommended strategies for disaster recovery in Oracle Fusion Middleware. Get ready to learn some key strategies for ensuring your Oracle HCM Site is protected in the face of any potential disruptions.
Recommended directory and file structure for Oracle Fusion Middleware
Oracle recommends a specific directory and file structure for Oracle Fusion Middleware, to ensure optimal availability and symmetry. It is essential for efficient backup and recovery, and upgrades to new versions.
The structure involves several directories and files such as:
- DOMAIN_HOME contains configuration files and scripts for managed servers.
- APPS_ROOT stores deployed applications.
- WL_HOME holds the WebLogic Server installation.
- ORACLE_HOME is the Oracle home directory with binaries and libraries.
- Finally, MW_HOME keeps product installation folders like WebLogic Server, SOA Suite, OSB, and more.
This structure promotes organization and efficient backups. It should be replicated across the primary and disaster recovery sites. This helps with DR testing, planning, execution, and documentation. To further enhance continuity, redundant binary installations with shared storage are recommended. This means that a backup copy of the software is always ready in case of any disruptions.
In conclusion, Oracle strongly recommends this directory and file structure for optimal availability. It ensures efficient backup and recovery, and a backup copy of the software in case of disruptions.
Redundant binary installations and shared storage for maximum availability
Shared storage and redundant binary installations are key for optimal system availability. Priority number one: shared storage for peak performance and reliability. Priority two: redundant binary installations for fast recovery and high availability. This can be done by installing binaries on shared storage or a separate disk partition.
Shared storage doesn’t just boost performance, it also boosts reliability. Redundant binary installations ensure fast recovery times and high levels of availability should an outage occur. Cloud computing offers a solution for disaster recovery and workload resilience.
IDC predicts that by 2024, digitally transformed enterprises will generate more than half of global GDP. To ensure maximum availability, best practices such as using shared storage and redundant binary installations must be followed.

Steps for Creating a Production Site
Creating a production site is a crucial step in implementing Disaster Recovery with Oracle HCM Site Recovery. To ensure seamless business continuity, several prerequisites need to be fulfilled. These include setting up a Data Guard configuration, creating shared storage volumes, and setting up host name aliases. Implementing a recommended directory structure ensures maximum availability and symmetry of the system. Let’s explore these steps for creating a production site in detail.
Prerequisites for creating a production site
Creating a production site in Oracle Cloud Infrastructure with disaster recovery requires certain prerequisites to be met. These include:
- Setting up Oracle Data Guard, mount points, creating volumes on shared storage, and establishing hostname aliases.
- Having a specific directory structure for maximum availability, symmetry and redundant binary installations.
- Oracle HCM Site Recovery needs network infrastructure and environment setup in primary region.
- Recovery policies must be set up for each system and region. Creating backups and defining disaster recovery policies like failover and failback.
- Deployment architecture should allow for active/active and active/standby setups. Consider variations according to specific needs.
By meeting prerequisites and following guidelines, maximum availability and resilience is achievable when creating a production site with disaster recovery.
Setting up Oracle Data Guard configuration and mount points
When configuring Oracle Data Guard, some critical factors must be taken into account for successful disaster recovery. The primary db instance should be set to archivelog mode. This creates archived logs for the standby db. Following this, a standby control file should be generated and transferred via ‘CREATE CONTROLFILE’ SQL commands. Then Redo Transport Services should be configured to transport redo logs from the primary server to one or more standby servers.
Mount points also play an important role in Data Guard configuration. The active or standby mode mount points should be chosen according to their purpose. Standby databases need the same directory structures as primary databases for successful failover.
It is best to get help from an expert when setting up Oracle Data Guard. Best practices like separating system and data files, no spaces in filenames, backup plans, and hardware resource allocation should be followed.
Creating required volumes on shared storage
When it comes to disaster recovery with Oracle HCM Site Recovery, creating volumes on shared storage is a must. Here’s how:
- Make Logical Unit Numbers (LUNs) on the storage array.
- Present the LUNs to production servers running HCM components.
- Set up ASM disk groups using ASMCA or ASMCMD utilities.
- Add ASM dependencies to OCR/VOTING disks in clusterware.
Remember, shared storage should have redundant hardware, such as power supply units and network cards. ASM is also highly recommended for features like mirroring, fault isolation, and redistributing data after disk failures.
Set up host aliases for middle tier hosts to enable client failover during site failover situations. Best practices are key to achieving optimal outcomes when establishing disaster recovery with Oracle HCM Site Recovery or other complex systems.
Setting up host name aliases for middle tier hosts
It is key to create aliases for host names when setting up a disaster recovery solution for the Oracle Fusion Middleware stack. This allows apps to access their databases during a failover. Aliases must be configured at both the middle tier and database server levels.
Set up these aliases following standard guidelines. Make sure the names are easy to recall when disaster strikes. Update affected apps with the new alias to avoid disruption.
FQDNs are better than IP addresses as they are more permanent. Disable DNS caching at both the middle tier and database server levels to prevent system failures. Constantly review aliases on all systems.
By taking these steps, businesses can protect workloads and reduce risks of outages. Setting up host name aliases for middle tier hosts is an essential part of any high availability architecture design, and a best practice for modern enterprises.
Recommended directory structure for maximum availability and symmetry
Organizing directory and file structures is essential for Oracle Fusion Middleware disaster recovery. To get maximum availability and symmetry, a suggested structure is needed. Showing it in a table is helpful. The table should have columns as follows:
|Directories||Description||Shared (Y/N)||Read-Only (Y/N)||Clean-Up Required? (Y/N)|
To make directories redundant, the recommended structure must be applied. Set up storage devices with enough space. Duplicating web logic domains is necessary to manage directories hierarchically. Backing up data storage on external sources like tapes or the cloud gives increased security.

What is the recommended directory structure for maximum availability and symmetry in Oracle Fusion Middleware?
Oracle recommends a specific directory structure for maximum availability, symmetry in configuration, and isolation of components, which includes environment variables such as ORACLE_BASE, MW_HOME, WL_HOME, and ORACLE_HOME. An Oracle instance contains system components and has its own directory with updatable files. The DOMAIN directory stores Oracle WebLogic Domain information. ORACLE_HOME is the directory where a product suite is installed. WL_HOME contains necessary files to host an Oracle WebLogic Server. Oracle_Home refers to the location of Oracle Fusion Middleware. ORACLE_BASE is the base directory for Oracle product installations. For more information, see “Directory Structure Recommendations for Oracle SOA Suite.” This recommended structure facilitates backup and disaster recovery.
How can Oracle SOA and Oracle Identity Management Enterprise deployment topology be used to create a production site with DR?
Oracle Fusion Middleware allows for multiple SOA Managed Servers from a single binary installation. For maximum availability, it is recommended to use redundant binary installations with two Oracle homes installed in shared storage. Two different volumes should be used for the redundant binary location for additional protection, and storage replication is recommended. If multiple volumes are not available, mount points can be used to simulate the same mount location in a different directory in shared storage. It is recommended to separate the domain directory used by the Administration Server from the domain directory used by Managed Servers for symmetric configuration and failover isolation. The Administration Server’s domain directory must reside in shared storage for failover to another node with the same configuration. It is also recommended to place Managed Servers’ domain directories on shared storage, although local file systems are supported. This is especially important for production sites with a disaster recovery site. Before starting, ensure that prerequisites are performed, such as referring to Oracle Data Guard Concepts and Administration and related Maximum Availability Architecture collateral for more information, determining the Oracle Data Guard configuration based on data loss requirements and network considerations, creating mount points and symbolic links if required, creating required volumes on shared storage, and setting up host name aliases for middle tier hosts. The recommended directory structure should be used, which includes environment variables and provides maximum availability and symmetry.
