Dbvisit - The ultimate Oracle standby database solution
Affordable peace of mind for complete disaster preparedness
Save US$25,000* per processor as Oracle Enterprise Edition (EE) not required anymore
Dbvisit is database replication software and provides automatic updating of standby databases to achieve full Disaster Recovery capability.
Dbvisit is a real alternative for Oracle Data Guard without the cost and complexity, is more secure and works for Oracle 8i to 11g.
See a comparison between Dbvisit and Data Guard.
Dbvisit supports Oracle RAC, Oracle Standard Edition (SE) and other Oracle features such as ASM, OMF and Flash Recovery.
Dbvisit is being used worldwide in more than 18 countries. See our Dbvisit world map.
Disaster Recovery (DR) is vital, without it your business could shut down in an emergency. More and more companies are required to comply with
industry regulations in terms of security and data accountability.
Still many companies have been hesitant to take the full step to implement a Disaster Recovery
Strategy, because of the costs of upgrading to Oracle Enterprise Edition (EE). This is no longer necessary.

automatically managing your Oracle standby databases to achieve full Disaster
Recovery capability.
The list of companies already using Dbvisit is impressive. Check out some of our customers
and what they have to say about Dbvisit.
A standby databases is like having an online backup of your database instantly available 24 x 7.
There is no need to restore in the event of a disaster (which is very time consuming), as there is instant data recovery.
It is possible to switch over to the standby database in a matter of minutes to allow business continuity in an emergency.
Dbvisit also maximises return on standby hardware investment as processing loads can be offset from the primary database to the standby database.
For example, your standby database can be used to run large reports which would otherwise impact your primary database.
Dbvisit automates the switching between a standby database and a reporting database.
Or backup your database in the middle of the day from your standby database.
What is Dbvisit:
Dbvisit is enterprise class database replication software, and it fully automates the Oracle Standby Database solution.
Dbvisit provides high availability by ensuring that the standby database is automatically kept up to date with the
primary database. Download our Fact Sheet for a comprehensive overview of Dbvisit.
Why Dbvisit:
Dbvisit is a very cost-effective Oracle standby database solution compared with upgrading to Oracle Enterprise Edition (EE) to enable utilisation of Oracle Data Guard.
The price difference between Oracle Standard Edition One (SE1) and Oracle Enterprise Edition (EE) is US$25,000* per processor.
What is unique about Dbvisit:
Dbvisit runs as an executable and runs outside the database (not using PL/SQL packages or triggers),
which means it offers precise control over the timing of the updates and does not interfere with normal database processing.
Dbvisit does not run as an agent or daemon as these need to be monitored to ensure they are still active (note: Data Guard runs as a daemon).
Dbvisit compresses the archive logs before they replicated to the Oracle standby database. This greatly reduces the need to have a high bandwidth link.
Dbvisit is secure. It does not use complex SQL*Net configurations. This reduces the number of ports that need to be opened on the firewall and increases security.
Dbvisit uses ssh (secure shell) on Linux, Unix and Windows as the transportation mechanism.
Dbvisit can even replicate the database updates through the Internet to a remote standby server in a remote office where this database can be used for reporting purposes or current stock information.
What makes Dbvisit successful:
Dbvisit is a great simple alternative to Data Guard.
Dbvisit has all the main features of Data Guard and more. Dbvisit is much more secure than Data Guard.
There are no complex commands to learn and the database does not have to be reconfigured.
Dbvisit works with all version of Oracle (from Oracle 8i).
Dbvisit is a safe, robust, efficient and secure solution for any business wanting to achieve an enterprise class high availability environment within their organisation.
Dbvisit is the complete Oracle disaster recovery software to allow business continuity in an emergency. No manual steps are involved to keep the standby database completely up to date.
Peace of mind with Dbvisit:
Dbvisit will work with all configurations of Oracle which means if you change or upgrade your Database configuration, Dbvisit will continue to maintain your standby database(s).
The Oracle configurations it supports include: OMF, ASM, Flash recovery area, Oracle RAC.
Use Dbvisit together with Oracle RAC to give you high availability and disaster recovery at a cost-effective price.
Eliminate upgrade dependencies:
Dbvisit has been developed so that Dbvisit is compatible with all versions of Oracle (from Oracle 8i).
When Oracle is upgraded or patched to a new version, Dbvisit will not have to be upgraded.
Dbvisit will continue operating when the databases are upgraded to new releases.
Dbvisit will continue operating when Oracle is migrated from 32bit to 64bit or from one operating system to another.
Dbvisit Key Features:
- Time-delayed standby database updating enabling data loss due to human error or software error to be recovered.
- Supports Oracle versions 8i to 11g, both 32 bit and 64 bit
(may support Oracle 7.3 and 8.0 in come cases). - Dbvisit works with Microsoft Windows, Unix, Linux and Itanium Linux.
- Simple to install and configure. Dbvisit on Windows comes with a modern Windows installer. With Dbvisit, any Oracle DBA can have a fully automated process to keep the standby database up to date in less than 30 minutes. Database does not need to be shutdown or restarted to install Dbvisit. Database init.ora parameters do not need to be modified.
- Multiple standby databases from the same primary database. Each standby database has its own schedule, parameters and thresholds.
- Switch back to the "old" primary database after a disaster with automatic graceful switchover. This is a seamless automated operation done in a matter of minutes with no dataloss. This works with Oracle 8i, 9i, 10g and 11g.
- Provides automatic graceful switchover which may be used for planned outages. This is a reversible role transition between the primary database and a standby database with no data lost during the switchover operation. Automatic switchover works with Oracle 8i, 9i, 10g and 11g.
- Supports Oracle RAC (Real Application Cluster) with Dbvisit RAC Takeover on SE (Standard Edition).
- Automatic space management. Dbvisit will automatically add datafiles and tablespaces to the Oracle standby database which have been added to the primary database.
- Supports Oracle flash recovery area and ASM filesystems.
- Checksum calculation is used to ensure that the updates have been replicated correctly. Dbvisit automatically resends the updates if checksums are not correct providing a completely "hands free" operation.
- Logs are compressed before being transferred to the Oracle standby database. This means that the link between the production database and the standby database does not need to be a high speed link.
- Very secure. Secure shell is standard (even on Windows). SQL*Net is not used. No extra ports need to be opened on the firewall.
- Dbvisit can also stop, start and open normal and open standby databases in read only mode with simple commands which can be scheduled.
- Automatic notification included. Notification thresholds can be set.
- Fully automated management and monitoring of the Oracle archive logs on both the primary and standby server. If space becomes an issue, automatic notifications will be sent, and archive logs can be automatically removed if required.
- Resends specific log files, and resynch with standby database if the standby database is rebuilt.
- Dbvisit is external to the database and cannot conflict with normal Database operations, and minimizes the impact on database performance. Dbvisit does not use Database triggers.
- Site specific pre and post commands are supported.
- Full reporting available about the replication process.
- Dbvisit produces comprehensive trace files which can be analysed by Dbvisit support for fast turnaround time on any issue.
- Automatic continuation without intervention of the DBA when temporary network or database problems occur.
- Superior to automated log shipping. See a comparison between Dbvisit and log shipping.
- Simple alternative to Data Guard.
