IBM® i 7.4 の発表と合わせて、 IBM は、 IBM i 用の新規ライセンス・プログラム・プロダクト (LPP) IBM Db2® Mirror for i を提供します。 IBM i 7.4 のお客様が利用可能なこの新規オファリングは、 IBM i Db2 のアクティブ-アクティブ 2 システム構成によるほぼ連続的な可用性を可能にします。

Db2 Mirror for i は、目標復旧時間 (RTO) ゼロおよび目標復旧時点 (RPO) ゼロの、継続的なアプリケーションの可用性を必要とする環境に対応するように設計されています。この基礎テクノロジーは、統合 IBM i オペレーティング・システム機能に基づいており、データベース・レベルで密に結合されたアクティブ-アクティブ構成の 2 台のシステム間で、 IBM i 統合 Db2 データベースの 2 つのコピーが、挿入、更新、および削除を同期して複製できるようにします。アプリケーション・レベルでは、各アプリケーションをアクティブ-アクティブ構成またはアクティブ-パッシブ構成でデプロイできます。両方のオプションにより、ほぼゼロの RTO が可能になります。

The Db2 Mirror offering is designed to provide continuous application availability through IBM i operating system technology that mirrors database updates to two nodes synchronously, using Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE) network. Applications can be deployed in an active-active manner whereby each application server has simultaneous access to the database on both systems in the two-node active-active complex. If one of the database servers goes down, the application servers continue performing I/O operations to the other system in the mirrored pair. This configuration has the additional benefit of enabling workload balancing.

Applications can also be deployed in an active-passive manner whereby application servers will conduct write operations to one of the two systems in the two-system complex and, in the event that the primary goes away, the application groups will be switched to the secondary system. The active-active case will necessitate that the application servers be hosted separately from the database servers and be connected through a client/server construct such as JDBC. Note that IBM i JDBC drivers now contain alternate server fail-over support to automatically transition the JDBC request between systems when one connection is no longer available. For many IBM i application workloads, deployment is through the traditional 5250 emulation screen and contained in the same LPAR as the operating system and database. In this case, if the primary goes down, the database has been continuously replicated to the secondary system synchronously and is immediately available. The application will need to be restarted on the secondary system prior to the resumption of the workload processing.

When one of the systems in the Db2 Mirror configuration is not available, Db2 Mirror will track all update, change, and delete operations to the database table and all other mirror-eligible objects, and when the pair is reconnected, all changes are synchronized between the systems. This includes databases that reside either in an IASP or as part of the base system storage. To emphasize this point, Db2 Mirror is completely compatible with IASPs and, in fact, exploits IASPs for IFS support within the Db2 Mirror configuration. For non IFS objects, IASPs can be used but are not required. Additionally, Db2 Mirror supports applications using either traditional record-level access or SQL-based database access. Support for IFS and IFS journals is accomplished through deployment into an IASP, which can be configured as a switchable LUN or in a mirrored pair of IASPs through storage replication.

IBM i Option 48, Db2 Data Mirroring, is required for Db2 Mirror for i, so entitlement for Option 48 is automatically included with Db2 Mirror for i orders. Be sure that IBM i Option 48 is installed and a key is applied along with the Db2 Mirror for i Licensed Program Product.

Disaster Recovery can be achieved with various options, such as the PowerHA® SystemMirror® for i Enterprise Edition, full system replication, or logical replication.

Statement of good security practices

Top rule

IT system security involves protecting systems and information through intrusion prevention, detection, and response to improper access from within and outside your enterprise. Improper access can result in information being altered, destroyed, or misappropriated or can result in misuse of your systems to attack others. Without a comprehensive approach to security, no IT system or product should be considered completely secure and no single product or security measure can be completely effective in preventing improper access. IBM systems and products are designed to be part of a regulatory compliant, comprehensive security approach, which will necessarily involve additional operational procedures, and may require other systems, products, or services to be most effective.

Important: IBM does not warrant that any systems, products, or services are immune from, or will make your enterprise immune from, the malicious or illegal conduct of any party.

IBM Electronic Services

Top rule

Electronic Service Agent and the IBM Electronic Support web portal are dedicated to providing fast, exceptional support to organizations that have IBM Systems. The IBM Electronic Service Agent tool is a no-additional-charge tool that proactively monitors and reports hardware events, such as system errors, performance issues, and inventory. The Electronic Service Agent tool can help you stay focused on your company's strategic business initiatives, save time, and spend less effort managing day-to-day IT maintenance issues. Servers enabled with this tool can be monitored remotely around the clock by IBM Support, all at no additional cost to you.

Now integrated into the base operating system of IBM i, Electronic Service Agent is designed to automatically and electronically report system failures and utilization issues to IBM, which can result in faster problem resolution and increased availability. System configuration and inventory information collected by the Electronic Service Agent tool also can be viewed on the secure Electronic Support web portal, and used to improve problem determination and resolution by you and the IBM support team. To access the tool main menu, simply type smitty esa_main, and select Configure Electronic Service Agent. In addition, ESA now includes a powerful web user interface, giving the administrator easy access to status, tool settings, problem information, and filters. For more information and documentation on how to configure and use Electronic Service Agent, go to the IBM Electronic Service Agent website.

The IBM Electronic Support portal is a single internet entry point that replaces the multiple entry points traditionally used to access IBM internet services and support. This portal enables you to gain easier access to IBM resources for assistance in resolving technical problems. The My Systems and Premium Search functions make it even easier for organizations that are Electronic Service Agent tool-enabled to track system inventory and find pertinent fixes.


Increased uptime: The Electronic Service Agent tool is designed to enhance the Warranty or Maintenance Agreement by providing faster hardware error reporting and uploading system information to IBM Support. This can translate to less wasted time monitoring the symptoms, diagnosing the error, and manually calling IBM Support to open a problem record. Its 24 x 7 monitoring and reporting mean human intervention is not required to report errors.

Security: The Electronic Service Agent tool is designed to be secure in monitoring, reporting, and storing the data at IBM. The Electronic Service Agent tool is designed to securely transmit either through the internet (HTTPS or VPN) or modem to provide organizations a single point of exit from their site. Communication is one way. Activating Electronic Service Agent does not enable IBM to call into an organization's system.

For additional information, go to the IBM Electronic Service Agent website.

More accurate reporting: Because system information and error logs are automatically uploaded to the IBM Support Center in conjunction with the service request, you are not required to find and send system information, decreasing the risk of misreported or misdiagnosed errors. Once inside IBM, problem error data is run through a data knowledge management system and knowledge articles are appended to the problem record.

Customized support: Using the IBMid entered during activation, you can view system and support information in the My Systems and Premium Search sections of the IBM Electronic Support page.

My Systems provides valuable reports of installed hardware and software using information collected from the systems by Electronic Service Agent. Reports are available for any system associated with your IBMid. Premium Search combines the function of search and the value of Electronic Service Agent information, providing advanced search of the technical support knowledgebase. Using Premium Search and the Electronic Service Agent information that has been collected from your system, you are able to see search results that apply specifically to your systems.
