Dbvisit Standby version 7 is making use of a new directory structure in comparison to the previous version 5 and 6. The default location on Linux for version 5 and 6 was /usr/local/dbvisit but in version 7 the default location changed to /usr/dbvisit. You can however still install version 7 into any other custom location, example /opt/dbvisit. It is recommended not to install Dbvisit Standby in the home directory of the oracle Unix account (/home/oracle).

On Linux it is possible to have both version 6 and 7 installed side by side, but only one should be run at a time. Dbvisit Standby version 7 repository owner during installation defaults to "dbvisit7" and will not affect the default version 6 standby repository user which is called "dbvisit". This option can be used to first configure and test version 7 in the environment and once up and running you can remove the version 6 software and only use version 7. More on this option in the section "Installing version 7 side by side to version 6" located under the "Upgrading Dbvisit Standby - Linux/Unix" section.

The following section will provide you with the detail steps required to perform a new installation of Dbvisit Standby version 7.

Installation Steps

You can follow 7 basic steps to install Dbvisit Standby version 7. This section cover the installation of Dbvisit Standby on a Non-RAC environment.

The Dbvisit Standby version 7 installation use approximately 70MB of disk space, but as trace files and log files will be stored in this location, 200MB free space is the recommended minimum.

In version 7 the default installation location is /usr/dbvisit. We do recommend you use the default or /usr/local/dbvisit. This directory will be known as the Dbvisit Base directory from version 7.

Step 1: Create "Dbvisit Base" Directory

The first step is to create the Dbvisit Base directory. This is the directory into which Dbvisit Standby will be installed into. The default location is /usr/dbvisit

This directory should be owned by the Oracle Database software owner.

The following steps can be executed as the "root" user to create the directory and set correct permission:

[root@dbvlin101 ~]# cd /usr
[root@dbvlin101 usr]# mkdir dbvisit
[root@dbvlin101 usr]# chown -R oracle:oinstall dbvisit
[root@dbvlin101 usr]# ls -ld dbvisit
drwxr-xr-x 2 oracle oinstall 4096 Aug 21 11:13 dbvisit

Step 2: Download Latest Software

The first step is to download the latest available version from the Dbvisit web site http://www.dbvisit.com

Once the software is downloaded, you can copy it to a temporary location on your server.

The Dbvisit Standby software is available for different Operating Systems and versions as noted on the download web page.

In summary:

Files with -el4- in the name can be used for Oracle Linux and Red Had Enterprise Linux 4 (example - dbvisit-standby7.0.04-el4.zip)
Files with -el5- in the name can be used for Oracle Linux and Red Had Enterprise Linux 5 (example - dbvisit-standby7.0.04-el5.zip)
Files with -el6- in the name can be used for Oracle Linux and Red Had Enterprise Linux 6 (example - dbvisit-standby7.0.04-el6.zip)
IF the name also include -x86_64 then it indicates it is for 64bit installations, and if -i686 is part of the name, then it is for 32bit installations (example dbvisit-standby7.0.04-el6-x86_64.zip indicates a download file for Oracle Linux 6 (as well as RHEL6) 64bit installation). If there is no -i686 or -x86_64- then the installation is for both 32bit and 64bit environments.

In this example, we create a temporary directory called 7.0 in /home/oracle and copy the software download into this directory.

We now have the following structure:

oracle@dbvlin101[/home/oracle/7.0]: ls -l
total 44084
-rw-r--r-- 1 oracle oinstall 45089534 Aug 21 10:40 dbvisit-standby7.0.01_linux.zip

Step 3: Extract Software

The next step is to extract the software downloaded in the previous step as well as updating the install-dbvisit file permission to allow the execution option.

First use "unzip" to uncompress the downloaded software package, followed by using the "tar -xf" command to extract the archive. The steps are shown below:

oracle@dbvlin101[/home/oracle/7.0]: unzip dbvisit-standby7.0.01_linux.zip
Archive:  dbvisit-standby7.0.01_linux.zip
  inflating: dbvisit-standby7.0.01.tar
  inflating: README.txt
  inflating: online_user_guide_reference.txt
oracle@dbvlin101[/home/oracle/7.0]: ls -l
total 109844
-rw-r--r-- 1 oracle oinstall 45089534 Aug 21 10:40 dbvisit-standby7.0.01_linux.zip
-rw-rw-rw- 1 oracle oinstall 67165696 Aug 19 18:10 dbvisit-standby7.0.01.tar
-rw-rw-rw- 1 oracle oinstall      393 Jul 10 23:21 online_user_guide_reference.txt
-rw-rw-rw- 1 oracle oinstall    87875 Aug 19 14:17 README.txt
oracle@dbvlin101[/home/oracle/7.0]: tar -xf dbvisit-standby7.0.01.tar
oracle@dbvlin101[/home/oracle/7.0]: ls -l
total 109848
drwxr-xr-x 6 oracle oinstall     4096 Aug 21 10:50 dbvisit
-rw-r--r-- 1 oracle oinstall 45089534 Aug 21 10:40 dbvisit-standby7.0.01_linux.zip
-rw-rw-rw- 1 oracle oinstall 67165696 Aug 19 18:10 dbvisit-standby7.0.01.tar
-rw-rw-rw- 1 oracle oinstall      393 Jul 10 23:21 online_user_guide_reference.txt
-rw-rw-rw- 1 oracle oinstall    87875 Aug 19 14:17 README.txt

Step 4: Running the Dbvisit Installer

The next step in the process is to start the Dbvisit Standby installer. Once you have extracted the tar archive, you will notice a new "dbvisit" directory.

In this directory you will find an "installer" directory which contains the installation script to be executed. Before executing this script you need to make it "executable". This can be done as follow:

oracle@dbvlin101[/home/oracle/7.0]: ls -l
total 109848
drwxr-xr-x 6 oracle oinstall     4096 Aug 21 10:50 dbvisit
-rw-r--r-- 1 oracle oinstall 45089534 Aug 21 10:40 dbvisit-standby7.0.01_linux.zip
-rw-rw-rw- 1 oracle oinstall 67165696 Aug 19 18:10 dbvisit-standby7.0.01.tar
-rw-rw-rw- 1 oracle oinstall      393 Jul 10 23:21 online_user_guide_reference.txt
-rw-rw-rw- 1 oracle oinstall    87875 Aug 19 14:17 README.txt
oracle@dbvlin101[/home/oracle/7.0]: cd dbvisit
oracle@dbvlin101[/home/oracle/7.0/dbvisit]: ls
dbvnet	dbvserver  installer  standby
oracle@dbvlin101[/home/oracle/7.0/dbvisit]: cd installer
oracle@dbvlin101[/home/oracle/7.0/dbvisit/installer]: ls  -l
total 2648
-rw-r--r-- 1 oracle oinstall 2707057 Aug 19 18:10 install-dbvisit

oracle@dbvlin101[/home/oracle/7.0/dbvisit/installer]: chmod u+x install-dbvisit
oracle@dbvlin101[/home/oracle/7.0/dbvisit/installer]: ls -l
total 2648
-rwxr--r-- 1 oracle oinstall 2707057 Aug 19 18:10 install-dbvisit

Now that the install-dbvisit script has the correct permissions, you may execute this script to start the installer.

Below is the detail output of the installation process. In summary the following are performed

(note that in most cases just accepting the default values are recommended)

Start the installer using - ./install-dbvisit command
Provide the DBVISIT_BASE directory - /usr/dbvisit (default)
Confirm the Oracle Database software owner name - oracle (default)

>>> Thank you for using Dbvisit software!

At this stage you should now have the Dbvisit Standby software installed and if you selected to auto start Dbvnet (Dbvisit Networking) and Dbvserver (GUI) you will have a number of Background processes running. Below is example output listing these processes:

oracle@dbvlin101[/home/oracle]: ps -ef|grep dbv
oracle    6410     1  0 Aug21 ?        00:00:01 ./dbvnetd start 
oracle    6411  6410  0 Aug21 ?        00:00:00 ./dbvnetd start 
oracle    6414  6410  0 Aug21 ?        00:00:00 ./dbvnetd start 
oracle    6415  6410  0 Aug21 ?        00:00:00 ./dbvnetd start 
oracle    6416  6410  0 Aug21 ?        00:00:00 ./dbvnetd start 
oracle    6431     1  0 Aug21 ?        00:00:01 ./dbvserverd start 
oracle    6432  6431  0 Aug21 ?        00:00:00 ./dbvserverd start 
oracle    6434  6431  0 Aug21 ?        00:00:01 ./dbvserverd start 
oracle    6436  6431  0 Aug21 ?        00:00:00 ./dbvserverd start

Step 5: Repeat Installation on Standby Server

Dbvisit Standby needs to be installed on the Primary server as well as on the Standby server.

Before you continue with the next step you need to make sure you follow Step 1 to 5 above on all the servers in the standby configuration. When doing this, it is important to make sure the Dbvnet password provided during installation is the same on all the servers where you are installing Dbvnet. This password is used for secure communication and if different passwords are used between the primary and standby servers, you will not be able to establish a connection between these servers using Dbvnet.

Step 6: Testing Dbvnet Communication

Once you have Dbvisit Standby installed on all the servers, it is important to make sure that the communication between the Primary and Standby servers are working. This can be done by making use of the Dbvnet Test utility provided with the Dbvisit Standby installation - dbvnet-test, which is located under the dbvnet sub directory. When using the default path this utility will be in /usr/dbvisit/dbvnet/dbvnet-test

To test communication between the primary and standby servers you can run the following recommended test commands:

To perform a basic status check which confirms that the primary and standby server can communicate using Dbvnet:
- dbvnet-test [-s|--status] SERVER[:PORT]
To perform a more detail check, testing network connectivity, you can run the following:
- dbvnet-test [-f|--fulltest] SERVER:PORT

In the example below, dbvlin101 is the primary server and dbvlin102 is the standby server. Dbvisit Standby was installed using default values and no additional configuration has been performed at this stage. Dbvnet and Dbvserver is running on both nodes, but only Dbvnet is required and used for these tests:

Test 1: Basic Status Check

oracle@dbvlin101[/usr/dbvisit/dbvnet]: ./dbvnet-test -s dbvlin102:7890

>>> Determining Dbvnet status on server dbvlin102:7890...


    Dbvnet on server dbvlin102:7890 is running.

Test 2: Full Test - 10MB file is copied (and verified) between primary and standby

From 7.0.10, please make sure you specify the temp directory, example /tmp in this case. It must exist on both systems.

oracle@dbvlin101[/usr/dbvisit/dbvnet]: ./dbvnet-test -f /tmp dbvlin102:7890
 
>>> Determining Dbvnet status on server dbvlin102:7890...
    Dbvnet on server dbvlin102:7890 is running.
 
>>> Running file transfer round trip on server dbvlin102:7890...
    Creating file '/tmp/dbvnet-test.tmp' containing 10 MB of data... - done.
 
  > Transferring 'dbvnet-test.tmp' to server dbvlin102:7890
    Progress: 0%...20%...40%...60%...80%...100% [11046 KB/s] - done.
 
  > Retrieving file "dbvnet-test.tmp" from server dbvlin102:7890
    Progress: 0%...20%...40%...60%...80%...100% [11209 KB/s] - done.
    Comparing checksums: all three checksums (local/remote/local) are
    identical. File transfer round trip finished successfully.

Stop and Start Dbvnet

Dbvnet can be stopped and started using the dbvnetd executable located in the dbvnet sub directory (example - /usr/dbvisit/dbvnet). Below is an example of stopping and starting the Dbvnet background processes:

oracle@dbvlin101[/usr/dbvisit/dbvnet]: ./dbvnetd stop
oracle@dbvlin101[/usr/dbvisit/dbvnet]: ps -ef|grep dbvnet
oracle   12641 12446  0 09:20 pts/1    00:00:00 grep dbvnet
oracle@dbvlin101[/usr/dbvisit/dbvnet]: ./dbvnetd start
oracle@dbvlin101[/usr/dbvisit/dbvnet]: ps -ef|grep dbvnet
oracle   12643     1  0 09:20 pts/1    00:00:00 ./dbvnetd start
oracle   12644 12643  0 09:20 pts/1    00:00:00 ./dbvnetd start
oracle   12645 12643  0 09:20 pts/1    00:00:00 ./dbvnetd start
oracle   12646 12643  0 09:20 pts/1    00:00:00 ./dbvnetd start
oracle   12647 12643  0 09:20 pts/1    00:00:00 ./dbvnetd start
oracle   12649 12446  0 09:20 pts/1    00:00:00 grep dbvnet

You should run the above tests from both the primary and standby servers to ensure communication between primary and standby servers can be established. Once this is done you can continue to the next step which is the creation of a Dbvisit Standby Database Configuration (DDC) file.

Step 7: Accessing the GUI (Dbvserver)

If you selected to install the Dbvserver (GUI) and allowed the auto start option during the installation process you should now be able to connect to the web based GUI interface.

To access this interface you can use http or https and the specified port you specified during installation. The default is https with port 8443 and you should be able to connect to the web based frontend using the following url: https://yourservername:8443

Example below is connecting to the GUI on dbvlin101 (172.16.1.111) using https and port 8443.

When asked for a username and password you need to provide the username and password specified during installation.

Summary

If you followed the above steps you should now have Dbvisit Standby installed on both your primary and standby servers.

You are now ready to move on to the next step which is to configure Dbvisit Standby.
