Add-on Modules for the Versant Object Database.
If mission critical deployments are a part of your business or if you need to access data through SQL, Versant provides Enterprise-class Add-on Modules for the Versant Object Database.
The observation of a production system is a cornerstone to the proper establishment of an adequate System & Network Management policy.
Using Versant Vitness for the advanced monitoring of your entire Versant Object Database environment provides you with a fundamental tool for all database administration operations and decisions.
The Vitness add-on module delivers real-time views of performance data and analytical information about the Versant Object Database at the push of a button. Proactive database monitoring prevents potential faults that could be unexpectedly generated by an unobserved system - Versant Vitness alerts administrators before database availability is affected. Can life get any easier?
Versant Vorkout is a Database Reorganizer Tool for applications that delete large numbers of objects. It lets you reclaim unused space in your database while it is in normal operation, increasing available free space and improving database performance. Last but not least Vorkout is tightly integrated and can be used through Versant Vitness.
Over time as objects grow or are deleted, empty holes are created in the tightly packed database resulting in fragmentation of data segments. Thus, performance starts degrading and disk usage is also increased.
Versant has addressed this issue by introducing Vorkout - the enhanced tool provides the user the ability to analyze a database for wasted space and reorganizes the data for reduced fragmentation and restored performance.
Vedding is an add-on software module for the Versant Object Database enabling automatic fail-over and recovery in the case of hardware or software failure. This is commonly known as a Fault Tolerance environment.
Vedding uses synchronous replication between two database instances and supports transparent re-synchronization in the event of a failure. Synchronous database replication mirrors the contents of one database to another in a predictable and orderly manner. This provides either local or geographically remote redundancy, which protects against the unavailability of data.
The Vhistle add-on module for Asynchronous Replication supports both master-slave and peer-to-peer asynchronous replication between multiple Versant Object Database servers. This can be used to replicate data to a distributed recovery site or to replicate data between multiple local object servers for increased performance and reliability.
In many applications, there is a need to replicate data, typically to improve availability, to improve performance by geographically co-locating databases with the applications that access the databases, to isolate decision support systems from online production systems, and to help in recovery from failures using warm-standby systems.
Vhisper provides Warm Standby capabilities to a Versant Object Database. The add-on module is used as an incremental rollforward recovery. It is designed to minimize the downtime in an emergency event.
With Vhisper, an up-to-date copy of the primary database is maintained - this is a Warm Standby database. In case of an emergency, the Vhisper's Warm Standby database can be updated very quickly to the state of the primary database. Instead of starting a full database restore that may take a considerable time with large databases, you just need to apply the last roll forward archive plus the logical.log of the primary database to the Warm Standby database - and you are ready for anything.
Varehouse is an add-on software module that enables the Versant Object Database to use the disk mirroring features of EMC Symmetrix or other enterprise storage systems to take an online backup of very large data volumes without impacting availability (High Availability Backup, HAbackup).
Varehouse, Versant's High Availability Backup solution, is a generic way of achieving continuous online backup of the Versant Object Database. It exploits the capabilities of special storage devices. It allows the user to execute certain operations such as, splitting a mirrored device, after bringing the database to a consistent state.
Vildcard enables you to run a discounted standby server in parallel to your initial Versant Object Database server.
Most likely, Vildcard is used for generic cold standby environments where backups are accomplished manually in certain periods.
reVind is an Add-on module for the Versant Object Database. The Versant/SQL suite of software modules permits you to use conventional Structured Query Language (SQL) semantics to access data that resides in a Versant Object Database.
The resulting application architecture can offer the strengths of both the relational and the object database models, such as the openness and interconnectivity of relational tables along with the expressiveness and performance of object collections.
