Robust

In the event of a failure Dbvisit Standby ensures you can switch applications over to the standby database in a matter of minutes, saving you the inconvenience of dealing with restoration delays, undue pressure on other systems and hardware unavailability. Every database change is replicated to the standby database and security is at the core of Dbvisit Standby’s design.

  • Automatic continuation, without human intervention, freeing up DBA resources 
  • No database triggers needed to avoid operational conflicts and performance issues
  • Provides advanced options such as compression, monitoring and encryption
 
  • Save up to 80% on Oracle Licensing - affordable with long term savings
  • Robust, Trusted, Proven
  • Maximize your standby database Return On Investment (ROI) with additional uses enabled
 

Save on time and money

Maintaining your database and protecting it against failures is an essential part of the DBAs job. Without the right tools it can prove to be the most unproductive part of it too. Because Dbvisit Standby gives you control over your database environment it makes managing it less of a chore and frees up more time to focus on other activities. Additionally, the savings on license costs and maintenance fees are significant (up to 80%), as there is no need to upgrade to Enterprise Edition to utilise Data Guard and Dbvisit Standby requires you to license only the primary server.

Increase Return On Investment (ROI) with a single product

Dbvisit Standby is also used in the following scenarios to provide even further value for Standard Edition users:

  • Remote or local standby databases for comprehensive disaster recovery and instant protection for failover sites
  • Shadow environment to provide risk free investigation and resolution of database bugs or inconsistencies
  • Batch processing environment capturing snapshots of 'point in time' transactions for rollback purposes when errors occur
  • As a read-only reporting database to run large reports without impacting the primary database and server
  • To form part of a backup strategy speeding up the Mean Time To Recovery (MTTR) when restoring databases from tape
  • Providing a recent 'point in time' view of the primary database data, in read-only view mode, for access by a remote office
  • Bundled as the disaster recovery component of a software product offering
 

Peace of mind

Dbvisit Standby is backed by DbvisitProtect, providing support services designed to ensure your software continues to operate flawlessly with all Oracle updates and upgrades and new versions of your operating system.

Notes:
i - 12c Multitenant (Pluggable) databases are not yet supported, but planned for future releases.
ii - Graceful Switchover (role reversal) with an ASM primary database requires an ASM instance (not primary database) of 11g+.
iii - Maximum protection mode in Data Guard which offers 0% data loss comes with a high price and high performance costs which are unacceptable for most companies.
iv - We believe the decision to failover to the standby database should not be automatic, as it could just be a temporary glitch. However, the failover is a simple command in Dbvisit Standby and can be automated if this feature is required.

 

Dbvisit Standby does not use SQL*Net, it uses secure shell (ssh) mechanism even on Windows. Dbvisit Standby for Windows includes ssh software from Bitvise to securely transfer the updates to the standby server.
This makes Dbvisit Standby on all platforms very secure and servers are not compromised by using non secure ports and non encrypted transport mechanisms.

Graceful Switchover

Dbvisit Standby uses Graceful Switchover to seamlessly switch the primary database server back to the original configuration it was in prior to an outage.

Often called 'role reversal' because users are re-directed to the standby database, this process is often used to keep a working database available to all users during disaster recovery testing of the primary database server and planned outages for server maintenance or upgrades. It is done in a matter of minutes* with no dataloss.

Graceful Switchover is never used during a disaster when the primary database is no longer available. In the event of a disaster the Failover process signals the users that the standby database is now their primary database.

When installing Dbvisit Standby on an environment using ASM for database storage, the ASM instance (not the database itself) must be 11g+.

Archive Log Management

Unlike Oracle database files, Oracle archive logs need to be monitored and managed constantly to ensure optimal database operation. If poorly managed they use up all the available disk space, cause the entire database to freeze and stop any updates or insert operations from happening.

Easy to configure, the Dbvisit Standby Archive Log Management Module (AMM) fully automates the management and monitoring of Oracle archive logs on both the primary and standby servers.

  • Alerts through email when Oracle archive logs have reached a set threshold of available disk space
  • Deletes Oracle archives logs after a set number of days
  • Deletes Oracle archive logs after available disk space has been used up
  • Ensures Oracle archive logs have been sent to standby database before removing any logs
  • Integrates with backup software to ensure logs have been backed up before removing
 

Reporting Database

With Dbvisit Standby it is possible to create a separate standby database that acts as reporting database or open the standby database for reporting purposes during the day. This offloads the processing overhead associated with report generation or schedules it to occur during off-peak times. All updates are applied automatically once the database is switched from reporting to standby mode with Dbvisit Standby used to manage scheduling.

Multiple Standby Databases

Dbvisit Standby enables multiple local-site or remote-site standby databases to be kept up to date from a single primary database. Each runs to its own schedule, can be used for different purposes and automatically synchronises with the primary database.

Real Application Cluster (RAC)

Dbvisit Standby can be used together with Oracle RAC to provide a scalable and high availability (HA) disaster recovery (DR) solution for your Oracle Standard Edition database. 

In the case of a RAC configuration, if one node fails Dbvisit Standby on another RAC node can take over the log shipment from the failed node automatically. 

As easy to set up and manage with Dbvisit Standby as a single instance database is, the RAC database does not require a restart or any of its Oracle parameters changed.

RAC primary and RAC standby database.

  • All primary nodes need to send the archive logs to a shared location on the RAC standby cluster
  • Dbvisit Standby only needs to be scheduled on one standby instance to apply the archives from all threads to the standby database

RAC primary and single instance Oracle standby database.

  • All primary nodes need to send the archive logs to the single standby node
  • Dbvisit Standby will apply the archives from all threads to the single instance standby database
