At any point in time post the installation it is possible to reset passphrase which was used to secure communication of dbvagentmanagers with dbvcontrol. It is also possible to reset Admin password for dbvcontrol which is used for login to the GUI console, if the password was changed from default and forgotten.
1. Reset Dbvcontrol and Dbvagentmanager Communication Passphrase
By default dbvagentmanager and dbvcontrol communication is secured with help of passphrase which user enters during installation. It is always possible to reset this passphrase if for example there is a need for adding dbvagentmanager without knowledge of the original passphrase.
The communication passphrase does re-generate certificate files which are very sensitive about correct system date. Before proceeding further, make sure that server time matches on all involved hosts. Otherwise the communication could keep failing (certificates will be valid in the future)
The reset of the passphrase must be alwalys done on:
dbvcontrol component
all dbvagentmanager components connected to the dbvcontrol
The order in which you perform the password reset for individual components doesn’t matter and communication will not be fully working until last component passphrase reset is done.
To reset the communication passphrase regardless whether dbvcontrol or dbvagentmanager you need to perform following steps as user which was used for installation of Dbvisit StandbyMP product:
A. Stop the component as described in: Starting and Stopping Dbvisit StandbyMP
For example:
sudo systemctl stop dbvagentmanager sudo systemctl stop dbvcontrol
B. Reset passphrase by runnig command
on Linux:
cd /usr/dbvisit/standbymp/bin ./change-passphrase
Never use root user for running change-passphrase
on Windows:
cd "C:\Program Files\Dbvisit\standbymp\bin" change-passphrase
C. Start the component as described in: Starting and Stopping Dbvisit StandbyMP
For Example:
sudo systemctl start dbvagentmanager sudo systemctl stop dbvagentmanager
If dbvcontrol is installed together with dbvagentmanager on standby server, it is needed to run change-passphrase only once
After performing these steps on all involved components, the communication passphrase will be successfully reset.
2. Reset Dbvcontrol Webserver Console Admin Password
You can at any time reset admin password for dbvcontrol which is used for login to the GUI console. You will need to run following command on server where dbvcontrol is installed, on Linux:
cd /usr/dbvisit/standbymp/bin ./dbvcontrol reset-admin-password
and on Windows:
cd "C:\Program Files\Dbvisit\standbymp\bin" dbvcontrol.exe reset-admin-password
The change is immediate an no restart of dbvcontrol is needed
