Amazon Web Services: Upgrade to Dbvisit Standby 8

By November 19, 2016 Cloud No Comments

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

[oracle@primaserver installer]$ ./install-dbvisit
-----------------------------------------------------------
Welcome to the Dbvisit software installer.
-----------------------------------------------------------
It is recommended to make a backup of our current Dbvisit software
location (Dbvisit Base location) for rollback purposes.
Installer Directory /home/oracle/dbvisit/dbvisit8/dbvisit
>>> Please specify the Dbvisit installation directory (Dbvisit Base).
The various Dbvisit products and components - such as Dbvisit Standby,
Dbvisit Dbvnet will be installed in the appropriate subdirectories of
this path.

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.

[oracle@primaserver installer]$ ./install-dbvisit

Our upgrade is now finished, let’s connect to the administration GUI
dbvisit8_1

And after logging we can import our previous configurations by using MANAGE CONFIGURATIONS
