Installing Dbvisit Standby 7 between two AWS Linux Instances

By November 19, 2016 Cloud No Comments

Dbvisit is compatible with Amazon Cloud. In this article we are going to talk about installation of Oracle SE2 and Dbvisit Standby 7 between 2 AWS linux instances. We suppose that ssh equivalence is configured for user oracle used for dbvisit installation.
First we have to install oracle software on both servers: primaserver and standserver.
To Install oracle-rdbms-server-12cR1-preinstall.x86_64 package yum can be used to configure the repository

[root@primaserver yum.repos.d]# wget http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol7 -O /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
--2016-11-14 03:52:34-- http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol7

[root@primaserver yum.repos.d]# cd /etc/yum.repos.d/
[root@primaserver yum.repos.d]#
[root@primaserver yum.repos.d]# wget http://public-yum.oracle.com/public-yum-ol7.repo

[root@primaserver yum.repos.d]# yum install oracle-rdbms-server-12cR1-preinstall

Then after Oracle installation can be launched. Note a silent method is used. Below an example of the response file I used

[oracle@primaserver response]$ cat db_install.rsp | grep -v ^#
oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_schema_v12.1.0
oracle.install.option=INSTALL_DB_SWONLY

Launching Oracle Installer

[oracle@primaserver database]$ ./runInstaller -silent -ignoreSysPrereqs -responseFile /home/oracle/db_install.rsp
Starting Oracle Universal Installer...
Checking Temp space: must be greater than 500 MB. Actual 13016 MB Passed
Checking swap space: 0 MB available, 150 MB required. Failed <<<< >>> Ignoring required pre-requisite failures. Continuing...
Preparing to launch Oracle Universal Installer from /tmp/OraInstall2016-11-14_08-26-42AM. Please wait ...[oracle@primaserver database]$ [WARNING] [INS-13014] Target environment does not meet some optional requirements.
CAUSE: Some of the optional prerequisites are not met. See logs for details. /tmp/OraInstall2016-11-14_08-26-42AM/installActions2016-11-14_08-26-42AM.log
ACTION: Identify the list of failed prerequisite checks from the log: /tmp/OraInstall2016-11-14_08-26-42AM/installActions2016-11-14_08-26-42AM.log. Then either from the log file or from installation manual find the appropriate configuration to meet the prerequisites and fix it manually.
You can find the log of this install session at:
/u01/app/oraInventory/logs/installActions2016-11-14_08-26-42AM.log

Once Oracle installed let’s create a database ORCL in the primary server with dbca in a silent method

[oracle@primaserver bin]$./dbca -silent -createDatabase \
-templateName General_Purpose.dbc \
-gdbname ORCL -sid ORCL -responseFile NO_VALUE \
-characterSet AL32UTF8 \
-sysPassword root \
-systemPassword root \
-createAsContainerDatabase false\
-databaseType MULTIPURPOSE \
-automaticMemoryManagement false \
-storageType FS \
-ignorePreReqs

Now it’s time to install dbvisit standby on both servers. The different steps are unzipping the software and running the installer. Output is truncated. But before don’t forget to edit your Security Groups (see blog ) to allow traffic on the differents involved ports .

[oracle@primaserver dbvisit]$ unzip dbvisit-standby7.0.62-el7.zip
Archive: dbvisit-standby7.0.62-el7.zip
inflating: dbvisit-standby7.0.62-el7.tar
[oracle@primaserver dbvisit]$ ls
dbvisit-standby7.0.62-el7.tar dbvisit-standby7.0.62-el7.zip
[oracle@primaserver dbvisit]$ tar xvf dbvisit-standby7.0.62-el7.tar


[oracle@primaserver installer]$ pwd
/home/oracle/dbvisit/dbvisit/installer
[oracle@primaserver installer]$
[oracle@primaserver installer]$ ./install-dbvisit
-------------------------------------------------------------------------------
Welcome. Your Dbvisit product is going to be installed in a moment.
It will be required by you to enter some configuration parameters
during installation.
-------------------------------------------------------------------------------
It is recommended to make a backup of our current Dbvisit software
location for rollback purposes.
>>> INSTALLATION DIRECTORY
Please specify the Dbvisit main installation directory.
The default directory is "/usr/dbvisit".
Note: the various Dbvisit products and components - such as Standby,
Replicate, Dbvnet, and Dbvserver - will be installed in the appropriate
subdirectories of this path.
Enter a custom value or press ENTER to accept default [/usr/dbvisit]:

-------------------------------------------------------------------------------
ABOUT TO CONFIGURE: DBVISIT STANDBY
-------------------------------------------------------------------------------
Dbvisit Standby is Dbvisit's disaster recovery software for your
Oracle database.
>>> ORACLE USER NAME
Please specify the Oracle user name on this server.
The default user name is "oracle".
Note: you must be logged in as the Oracle user to run Dbvisit installer.
Custom value or ENTER for default [oracle]:
..........
..........
>>> IMPORTANT - PLEASE NOTE THE FOLLOWING REQUIREMENTS BEFORE CONTINUING:
> The Dbvisit Standby, Dbvnet, and Dbvserver software must be installed
on both the primary and standby servers.
> For network communication between the primary and standby server
via Dbvnet port number 7890 must not be blocked by your firewalls.
> Dbvnet must be up and running on both the primary and standby servers
at all times.
> If you wish to use Dbvserver, the Dbvisit web interface, then please
ensure port 8443 is open on your servers' firewalls, as well.
>>> Thank you for using Dbvisit software!
[oracle@primaserver installer]$

Once dbvisit installed on both node, the graphical administration tool can be lauched using the public DNS.
dbvisit7_1
dbvisit7_2
To configure a standby database we can use the GUI or dbvisit_setup executable

[oracle@primaserver dbvisit]$ cd /u01/app/dbvisit/standby/
[oracle@primaserver standby]$ pwd
/u01/app/dbvisit/standby

The first step of the configuration is to create a new dbvisit database setup. Just launch dbvisit_setup, choose option 1 and follow instructions.

[oracle@primaserver standby]$ ./dbvisit_setup
....
....
....
Options:
1) New Dbvisit Database setup (combines options 2,3,4)
1a) New Dbvisit RAC Instance setup (combines options 2,3,4)
2) New Dbvisit Database configuration (DDC) file setup
3) New Dbvisit Archive Management Module (AMM) setup
4) New Dbvisit Database repository (DDR) setup
5) Manage Dbvisit Database repository (DDR)
6) Update Dbvisit Database configuration (DDC) file
7) Create Standby Database (and template)
8) Synchronize Standby Database
9) Uninstall Dbvisit Database repository (DDR)
E) Exit
=========================================================
Please enter choice : 1

And then after  we can create standby database by running again dbvisit_setup, choose option 7  and follow instructions.

[oracle@primaserver standby]$ ./dbvisit_setup
=========================================================
