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.
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.
