In a previous blog we installed Dbvisit Standby 7 on two AWS linux instances. In this article we are just upgrading to Dbvisit Standby 8. The first thing is to stop on both nodes dbvnet and dbvserver on both servers
[oracle@primaserver dbvnet]$ ps -ef|grep dbv|grep -v grep oracle 2062 1 0 04:53 ? 00:00:02 /u01/app/dbvisit/dbvserver/dbvserverd oracle 2064 2062 0 04:53 ? 00:00:00 /u01/app/dbvisit/dbvserver/dbvserverd oracle 2131 1 0 04:54 ? 00:00:00 /u01/app/dbvisit/dbvnet/dbvnetd oracle 2132 2131 0 04:54 ? 00:00:00 /u01/app/dbvisit/dbvnet/dbvnetd oracle 2142 2131 0 04:54 ? 00:00:00 /u01/app/dbvisit/dbvnet/dbvnetd oracle 2143 2131 0 04:54 ? 00:00:00 /u01/app/dbvisit/dbvnet/dbvnetd oracle 2144 2131 0 04:54 ? 00:00:00 /u01/app/dbvisit/dbvnet/dbvnetd oracle 4036 2062 0 08:03 ? 00:00:01 /u01/app/dbvisit/dbvserver/dbvserverd oracle 4037 2062 0 08:03 ? 00:00:02 /u01/app/dbvisit/dbvserver/dbvserverd
[oracle@primaserver dbvnet]$ pwd /u01/app/dbvisit/dbvnet [oracle@primaserver dbvnet]$ ./dbvnetd stop [oracle@primaserver dbvnet]$ cd ../dbvserver/ [oracle@primaserver dbvserver]$ ./dbvserverd stop [oracle@primaserver dbvserver]$
The upgrade is done by launching dbvisit installer and must be done on both servers. The upgrade process consist out of two steps:
1-Upgrade (install) the new version 8 software
2- Upgrade the version 7 DDC files
It is important to take into account that Dbvisit Standby version 8 makes use of a central web based user interface (GUI). The GUI is no longer installed on each of the Database Servers being managed.So during the upgrade we will remove the current Dbvserver installation and will Install the Dbvisit Standby Core Components – Dbvagent, Dbvnet and Dbvisit Standby CLI

Let’s launch install-dbvisit executable

After software installation, we can now update Dbvisit Standby Configuration Files (DDC). Just note that dbvnet and dbvagent must be started on both servers. dbvctl is used for upgrading DDC file. In our case we have only one DDC file for our instance ORCL.
[oracle@primaserver dbvnet]$ ./dbvnet -d start [oracle@primaserver dbvagent]$ ./dbvagent -d start
[oracle@primaserver dbvisit8]$ cd /u01/app/dbvisit/standby/ [oracle@primaserver standby]$ pwd /u01/app/dbvisit/standby [oracle@primaserver standby]$ ls conf dbvctl doc gs lib log pid tmp trace [oracle@primaserver standby]$ ./dbvctl -d ORCL –o upgrade
The last step is to upgrade the central console dbvserver only on the primary server.
