These requirements must be satisfied for all Dbvisit StandbyMP installations.
1.1 Network
...
Communication Requirements
Dbvisit Standby Multiplatform has two components: dbvagentmanager (Agent) and dbvcontrol (Control Center). More information in Dbvisit StandbyMP concept: https://dbvisit.atlassian.net/wiki/spaces/DSMPV12/pages/4396875777/Introduction#2.-Dbvisit-StandbyMP-Components
...
| Info |
|---|
Dbvisit StandbyMP doesn’t support communication and synchronization network interface separation. Single interface must be used for dbvagentmanager and dbvcontrol communication and synchronization. |
1.2 Network Hostname Resolution Requirements
Dbvisit StandbyMP uses hostnames throughout the whole installation and database synchronization configruation. Usage of IP addresses is not recommended. You must verify that hostname resolution is equal on all hosts where you need to deploy Dbvisit. Hostname resolution can be tested by running:
| Code Block |
|---|
ping <primary hostname>
ping <standby hostname>
ping <dbvcontrol hostname> |
You need to run these commands on primary, standby and dbvcontrol server (if different from standby). The resolved IP addresses must match on all hosts. It is not required that the ping command receives response (for example Windows system prohibits ping by default).
| Info |
|---|
resolved IP addresses must be IPv4, IPv6 is not supported by Dbvisit StandbyMP |
In case you have not working DNS server or if resolved IP addresses differ, you must establish hostname resolution via hosts file on all hosts to correct this behavior.
Linux: /etc/hosts
Windows: C:\Windows\system32\drivers\etc\hosts
| Info |
|---|
we recommend you to remain consistent in hostnames: all hostnames should match case and include (or not include) domain name. Do not mix uppercase/lowercase hostnames and do not mix hostnames with domain names and without domain names. |
1.3 Storage Requirements
A. Storage Space Requirements
...
CIFS is not supported for Dbvisit StandbyMP deployment

...
4 CPU and Memory Requirements
| Note |
|---|
Requirements are cummulative, so if you place dbvcontrol component on standby server together with dbvagentmanager, you need to sum the memory and CPU amount. |
...
Total Database Count | CPU Threads | Memory (GB) |
|---|---|---|
2 | 2 | 4 |
up to 4 | 2 | 6 |
up to 8 | 4 | 8 |
up to 12 | 6 | 10 |

5 Dbvcontrol Webserver Browser Requirements
We recommend and support Chrome Browser for accessing dbvcontrol. However, other browsers such as Edge or Firefox will work as well. In case of any observed issues, we recommend to switch to Chrome Browser.

...
6 SMTP Server Requirements
Dbvisit StandbyMP uses SMTP server client to send notifications (which are optional). To use the notification feature, it is necessary that dbvcontrol component has direct access to SMTP Server.
...
Chronyd and ntpd services will ensure system date correct synchronization. If system date is not synchronized, there can be issues with connection issues because of certificates validity (which is based on actual date).
2.2 Windows
If When installing Dbvisit Standby StandbyMP onto a Windows Based environment the following pre-requisite checks should be performed:, user account is required to run the msi installer file and perform the setup. During installation you will be prompted for another username which will be user for installing dbvagenmanager Windows Service. They can be different accounts, but you can also use same account for both actions.
A. User performing Installation
This is can be any account (for example any named user administrator account ) who will perform Dbvisit StandbyMP software installation.
