High availability in Global Mailbox adheres to specific principles; however, there are limitations to its properties. Understanding these limitations is crucial for optimizing the high availability features of Global Mailbox.
Mailboxes:
Global Mailbox serves as a facility for establishing a directory of mailboxes with sub mailboxes, distributed across multiple data centers. Messages, created by Global Mailbox on behalf of applications or trading partners, are stored within these mailboxes.
Global Mailbox Management Tool:
Administrators have access to the Global Mailbox management tool, allowing them to efficiently oversee mailboxes, messages, permissions, virtual roots, and event rules within the Global Mailbox ecosystem.
Administrative Users:
Administrative users (admins) in Sterling B2B Integrator are endowed with all permissions in the Global Mailbox, ensuring seamless administrative control.
Event Management:
Global Mailbox administrators can craft event rules, automating specific actions triggered when messages are added to a Global Mailbox.
Functionality Achieved by Replication
The replication feature in Global Mailbox is fundamental to ensuring availability, performance, consistency, and durability within the system.
Storage:
The storage (file system) implementation in the Global Mailbox system revolves around the concept of storage buckets—logical groupings in the file system configured based on business requirements, emphasizing security and retention.
Scheduler:
Scheduled jobs, executed regularly in the Global Mailbox system, automate routine tasks to uphold optimal system performance. Configuration adjustments can be made using the schedulerConfigUtility script to align with specific system requirements.
Migration:
While you can convert Sterling File Gateway partners and mailboxes to leverage Global Mailbox, migrating users and mailboxes from one Global Mailbox system to another is not supported.
File Transfer Resumption:
Global Mailbox supports file transfer resumption, enabling the recovery of active file transfers that may be interrupted, disrupted, or stopped.
Global Mailbox REST Services:
The implementation of Global Mailbox includes support for REST services, offering the ability to view and consume resources in Sterling B2B Integrator and Sterling File Gateway.
Performance Considerations:
The performance of the IBM Global High Availability Mailbox system is influenced by component interactions, communication paths, and configuration settings. Monitoring and tuning are essential to balancing file transfer speed, availability, and data loss protection, aligning with specific business requirements.
Security Considerations:
Security for the Global Mailbox system necessitates meticulous planning and implementation as an integral aspect of deployment. Continuous monitoring and administration are vital for adapting to emerging risks and minimizing potential threats to the organization.
