• Dbvnet – Dbvisit Standby’s new Network Layer is one of the exciting new features introduced in this new release.  Dbvnet’s functionality removes the dependency earlier Dbvisit Standby versions had on SSH for providing network communication between the primary and standby nodes.  By making use of Dbvnet no additional SSH software is required to be installed, configured or maintained on Windows.  When using Linux, Dbvisit Standby can now be configured to make use of the new Dbvnet (default option) or if required, SSH can still be configured and used on Unix based systems.  
  Dbvnet is started as a background process and is run independent from the already known GUI (Dbvserver) background processes.  Dbvnet provides the following key features:

...

• New directory structure.  With version 7 a new directory structure is used.  As seen from the diagram below the base (DBVISIT_BASE) directory is “dbvisit” and the recommended default installation path is “/usr/dbvisit” on Linux and “c:\Program Files\dbvisit” when installed on Windows bases systems.

Below the base directory (dbvisit) three directories will be noted; one for each of the key Dbvisit Standby version 7 components:

...

• New Dbvisit Standby licensing.  Dbvisit Standby version 7 makes use of a new License module, and so a new license key is required.  License keys from older version will not be accepted.  For customers with current support contracts a new license key can be obtained from Dbvisit without additional cost.  The default evaluation (trial) period for new installations is still 30 days, after which the required license needs to be purchased to continue using the software.

• New Improved Pre- and Post- Processing scripts.  In version 7 the pre- and post- processing scripts have been improved and can now be executed as part of normal operation (send/apply) as well as part of an Activation of a standby database or even as part of a Graceful Switchover process.  A new DDC file parameter: DBV_PRE_POST_PROC is introduced as well as two sample scripts in the DBVISIT_BASE/standby/doc directory called: dbv_pre_post_processing.cmd (for windows) and  dbv_pre_post_processing.sh (for Unix)

• In addition to the above features and improvements, Dbvisit Standby version 7 include all features, changes or fixes implemented in version 6 (until version 6.0.50 54 – 11 July 17 December 2013)
