Beta and Release Candidate Changes

8.0.01 (07 November 2016) RC 1
1) Various internal enhancements
2) Include Windows Version
3) Updated documentation
4) Enhance access authorization in Central Console
5) Remove SSH option if using Windows in Central Console - Dbvnet must be used.
6) Various style and multiselect input enhancements in Central Console
7) Improve handling of Hostnames in Central Console
8) Various updates to installer script

10) Lower debug level for Dbvnet, Dbvserver, Dbvagent to value of 1
11) Update "Task log unavailable" message to "Retrieving task progress" to indicate process
12) Add new import DDC option in the Central Console Configurations Screen

8.0.01 (21 October 2016) Beta 3
1) Central Console updates:
- Database Actions are now grouped into logical groups
- Add new option to start the Dbvisit Standby Background (Daemon) process (Start/Stop/Status)
- Add new option to ship only one archive log to standby - similar to the -r option in CLI
- New confirmation option (Continue/Cancel) was added to remove/delete option for DDC, HOSTS and USERS
- Various Enhancements to DDC Upgrade process
- Added new progress indicators at various areas where actions are performed
- Add new option to update an existing license
- Improve error handling when a DDC is imported where primary or standby host is not yet defined in Central Console
- Create new configuration option is disabled if there is no hosts (agents) configured
- Resolve "in-progress" symbol spinning when viewing the Central Console via a RDP connection
- Add new "About" and "Documentation" links to bottom right of screen
- Activate new option to handle USER/HOST security - a user can be assigned to specific hosts. If a user does not have access to a host,
it will not have access to do anything with a DDC referencing that host
- Admin role - does not have any restrictions. It is important to note that only users with the admin user role can add new hosts

- Add support for creating an Oracle RAC primary to Oracle RAC standby (node count must match primary) DDC
- IMPORTANT: Note that the cluster on the standby must already be configured (GI and Database software must be installed and diskgroups
configured). It is recommended in this configuration that the standby Oracle RAC matches the primary Oracle RAC as much as possible
(disk groups, file locations). Using shared storage for the Dbvisit Standby installation is required with a new Virtual IP (VIP) that
is allocated with a hostname alias. This is used to identify the node that will be running the Dbvisit Standby processes. Using ACFS
is recommended for the shared filesystem.
