Latest Release Highlights

HPE Shadowbase for Other Servers, Version 6.300 was released for General Availability (GA) for the following platforms:

  • Windows (WIN),
  • Redhat Enterprise Linux (RHEL), and
  • SUSE Linux Enterprise Server (SLES).

HPE Shadowbase for IBM AIX, Solaris, and HPE/UX, Version 6.300 is scheduled for release later this fall. Highlights for Version 6.3 include:

  • Support for DB2 as a source database: source collection for DB2 requires IBM MQ and IBM DB2 Data Event Publishing for collection. Contact Shadowbase Support for more information.
  • HPE Shadowbase Log Source for Oracle supports Oracle 12c container databases: Oracle 12c container databases allow multiple user database instances to be administered in a single Oracle instance.
  • HPE Shadowbase Log Source for Oracle supports collecting from multiplexed log files in all collection modes.
  • The performance enhancements for DOC reading and writing initially implemented for OSS are available for all platforms.

More information on these enhancements and the myriad of other enhancements and fixes included in the release can be found in the release SOFTDOC.

Development is also wrapping up HPE Shadowbase for HPE NonStop, Version 6.4 and heading into Quality Assurance. It includes several important new features:

  • The new version of the collector, SBCOLL, now supports bi-directional replication for Enscribe files and SQL/MP tables (bi-directional replication of SQL/MX replication was already supported). SBCOLL is now our current collector and will receive the majority of future enhancements as we work to retire AUDCOLL (ADCOLLN) in a future release. If you are still using AUDCOLL/AUDCOLLN in your configuration, please consider changing to use SBCOLL going forward.
  • We have added a much requested feature to prevent erroneous updates in a sizzling-hot-takeover (SZT) configuration by preventing the target database from replicating back to the source database. With this feature, Reverse Replication Cutoff, you can configure how the collector on the target system handles events that would normally be replicated back to the source system. The collector can be configured to:
    • Suspend when it sees an event to be replicated,
    • Skip the event and continue reading the audit trails, or
    • Replicate the event.

Of course, the normal bi-directional cutoff processing still happens; the cutoff only applies to events generated outside of replication from the source to the target. This enhancement was of particular interest to active/passive RDF customers when they migrated to HPE Shadowbase software.

Additional features to note:

  • We added support for large Enscribe entry sequenced files (added in L17.08).
  • We added a new utility for generating create scripts for SQL databases from DDL (Enscribe) record definitions.
  • We simplified configuring bi-directional replication for most environments.

I would like to remind everyone that the current release of the HPE Shadowbase for NonStop includes support for the first phase of our synchronous replication and zero data loss software, HPE Shadowbase ZDL. While we are still working with HPE on the product rollout details, it is available for qualified accounts for testing purposes only in this release (as an HPE Shadowbase “TCD” release). Please contact Shadowbase Support if you are interested in testing synchronous replication.

For our customers who purchased Shadowbase software through HPE, all of the GA releases are available through HPE NonStop Scout. (All other customers can receive the releases directly from Gravic; contact Shadowbase Support for instructions on downloading the release.) Please visit our website page, HPE Shadowbase Product Releases (SPRs) Available from HPE Scout, for tables that list the most recent SPRs for the HPE Shadowbase product line. These tables will assist with determining the components and their latest GA versions, organized by HPE Product ID/SKU, and by HPE Shadowbase part number (T#), which correlates to its respective operating system.

Coming Soon

Looking forward, we continue to improve the HPE Shadowbase product suite with HPE Shadowbase ZDL. Synchronous replication is an ongoing development focus with several releases planned in the coming years.

While we work on enhancing synchronous replication, we are not ignoring our core asynchronous replication products. Other planned enhancements include:

  • Further enhancements to our support for SZT configurations,
  • Better parallelism for heavily updated tables by further partitioning replication of a single table or partition down multiple threads,
  • Enhancements to Shadowbase Compare, to support better parallelization of compare sessions and correction for mismatched data, and
  • DOC encryption and decryption for data at rest protection.

As always, please keep us abreast of your future technology direction, needs, and wants in the data replication, data integration, and data synchronization space so we can plan to meet them accordingly.
