Was it Einstein who once said "Things should be as complex as they need to be, but no more ..."?
Dbvisit - Oracle Standby Database Solution within your reach
Dbvisit benefits:
- Complete protection from all types of failures, including software and human errors, faulty batch jobs, sabotage as well as natural or manmade disasters.
- Distance independency between production and standby systems due to compression with minimum bandwidth requirement.
- Simple failover process in case of failure or disaster.
- Usability of the standby systems for additional purposes (e.g. reporting, backups, analysis) without any impact on the production systems during normal operations.
- Continuous and consistent backup of your databases.
- Ability to reverse database roles to minimize downtime.
- Increased DBA job satisfaction giving DBA's more time to focus on core business functions.
- Simplifies the process by automatically creating the standby database.
Dbvisit features:
- Time-delayed standby database updating enabling data loss due to human error or software error to be recovered.
- Automatic creation of the Standby Database from normal, RAC or ASM database (with restartability).
- Automatic gap identification with conflict resolution.
- Failover to backup or standby database in case of disaster or severe outage.
- Supports Oracle versions 8i to 11g, both 32 bit and 64 bit
(may support Oracle 7.3 and 8.0 in some cases). - Supports all Oracle editions from Enterprise Edition (EE), Standard Edition (SE), Standard One to Oracle Express Edition (XE).
- 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) on SE (Standard Edition).
- Supports Oracle flash recovery area and ASM file systems.
- Dbvisit automatically resends the logs incase of network issues.
- 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 (with encryption) 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 including timings of the compression and transfers.
- Backup or standby database can be used for BI, dataware housing or reporting purposes.
- Provides full archive log gap and transfer log gap reporting.
- Dbvisit produces comprehensive trace files which can be analyzed by Dbvisit support for fast turnaround time on any issue.
- Automatic continuation without intervention of the DBA when temporary network or database problems occur.
- All database changes are replicated to the standby database. There are no exceptions.
- Superior to automated log shipping. See a comparison between Dbvisit and log shipping.
- Simple alternative to Data Guard. See a comparison between Dbvisit and Data Guard.

- Automatic space management. Dbvisit will automatically add datafiles and tablespaces to the Oracle standby database which have been added to the primary database. Works for Oracle 8i and above.
- Creates the standby database.
