HPE Remote Database Facility (RDF) Migrations

RDF Limitations

• RDF requires Expand (TCP/IP is not supported)
• RDF is limited to:
  • Asynchronous active/passive (only) business continuity replication
  • Synchronous active/passive (only) business continuity replication (via RDF/ZLT, which requires XP SAN arrays – a distance-limited solution)

Fortunately, HPE Shadowbase products provide all of the RDF capabilities, plus additional features. HPE Shadowbase software should be actively considered by all RDF sites; many of which have already made the switch.

Additional HPE Shadowbase features beyond RDF

• Sizzling-Hot-Takeover (SZT) and Active/Active Replication
• Zero Data Loss (ZDL) and Synchronous Replication (does not require XP SAN arrays)
• Data Integration and Application Integration
• Data Transformation
• Replication to Other Servers
  • Platforms (e.g., Linux, Windows, Unix, Solaris, AIX, and HP-UX)
  • Databases (e.g., Oracle, SQL Server, DB2, SAP HANA, Sybase, and MySQL)
• Communications over Expand and TCP/IP
• Shadowbase User Exits provide extensibility
  • Add custom code snippets into the replication engine
• Compare and Repair Data
  • Identify source and target database discrepancies
  • Validate for key stakeholders that the source and target match (repair the target database when they do not)
  • Run while database(s) are actively being read and updated (does not require an outage)
  • Intelligent false-positive recognition (e.g., mismatch in databases due to replication latency)
• HPE Shadowbase Essentials (tools and utilities for data management)

Migrating HPE NonStop non-audited data, programs, and script files

Other HPE products are available to assist migrating to HPE Shadowbase solutions:

• HPE AutoTMF or Shadowbase SOLVMGR is required if the customer is replicating non-audited NonStop Enscribe data
• HPE AutoSYNC is required if the customer is replicating NonStop programs and script files to another NonStop node
• See Enabling Technologies

Note: Replacing a competing product with HPE Shadowbase software may require HPE Professional Services to replace existing customizations. Please contact us on how to assess and size your project.
