1. Introduction
From Dbvisit standby MultiPlatform version 11.3, all the command line operations for Oracle can be performed like the previous version (Standby 10.2,9.0.20) with the exception of Automated standby update. This is to provide customers using only CLI to be the ability to upgrade to the latest version without needing to use GUI.
Even though all operations can be performed using CLI, it is mandatory to install both agentmanager and control center (The control center needs to be installed only once).
The automatic send and apply archivelogs are enabled by default when DDC is created. Below code snippet shows the listener process running.
[oracle@dbvel81 oracle]$ ps -ef | grep dbv
oracle 14173 1 0 19:40 ? 00:00:03 /opt/dbvisit/standbymp/bin/dbvagentmanager service run

oracle 39705 14295 0 20:44 ? 00:00:01 /opt/dbvisit/standbymp/oracle/dbvctl -d TEST01 --listener start --mode GUI
oracle 40306 14295 0 20:55 ? 00:00:02 /opt/dbvisit/standbymp/oracle/dbvctl -d TEST01 -D run --mode GUI
oracle 40444 15071 0 21:03 pts/0 00:00:00 grep --color=auto dbvAs soon as the standby database is created, the listener process would start sending archivelogs from primary to standby, and the listener process on the standby would apply the archivelogs using the default time gap of 600sec. This can be changed by editing the dbv_<DDC>.env file with the parameter DMN_DBVISIT_INTERVAL on the primary from 600 to desired value. The parameter must be modified only from the file on the primary server. The default location of the file is under /usr/dbvisit/standbymp/oracle/conf directory on Linux and c:\Program Files\dbvisit\standbymp\oracle\conf directory on the Windows.
This method is a stop gap measure for version 11.3. From the next release the automatic standby update can be directly controlled from dbvagentmanager command line.
2. Creating a Dbvisit Standby Configuration (DDC) File - Command Line
2.1. Creating a DDC - Using Filesystem-Based Storage
Below is a summary of the environment that will be used in this example:
This environment will not be using ASM for database storage
Primary Server: dbvel81
Standby Server: dbvel82
Primary Database Name: TEST01
Primary Database Unique Name: TEST01
Standby Database Unique Name and SID will be the same: TEST01
Dbvisit Standby ARCHSOURCE location on the primary server: /u01/app/oracle/dbvisit_arch/TEST01
Dbvisit Standby ARCHDEST location on standby server: /u01/app/oracle/dbvisit_arch/TEST01
The Dbvisit Base directory is /opt/dbvisit
Dbvisit Standby Multiplatform is already installed on both the primary and standby servers

If the standby database will be Oracle RAC enabled:
Enter the the Virtual Hostname (linked to a Virtual IP) for standby database.
This virtual hostname is attached to a VIP that will be able to move between
the RAC nodes. Dbvisit Standby will only run on the server where this virtual
hostname (VIP) resource is running.
The Virtual Hostname (and VIP) should be configured as a resouce in clusterware
and must be enabled and started on one of the nodes before yo continue with the
setup. If you are not using a Virtual Hostname (Highly Recommended), Dbvisit
Standby can only be configured to run on one dedicated node in the RAC
configuration - specify the hosts name here if you do not have a Virtual
Hostname (attached to VIP) for the cluster configured.
For non-RAC configurations specify the standby database server name here.
