Introduction

This guide will provide you with an overview on getting started with  Dbvisit Replicate and Amazon EC2 The scenario used in this guide can be illustrated as:


This document will provide you with an overview on the steps required to implement the above solution.  

Source (MINE) Server

Dbvisit Replicate will be installed on the database server, from where the mine process will be configured.  

 

Before starting the Dbvisit Replicate configuration, make sure you have the following details of the Source Database server where the mine process will be configured.  (Note that in this guide it is assumed that the source server is Unix based):

  • Server Name
  • Server IP Address (Make sure that you have an internal and external IP address.  Talk to your admin about firewalls.)
  • Oracle (Unix User) password
  • Source Database Name
  • Source TNS Alias (Make sure it is located in local tnsnames.ora)  also have the full path ready
  • SYS  password
  • SYSTEM password                 
  • List of Schemas or Objects you want to replicate      
  • Sufficient disk space to store Dbvisit Replicate Mine PLOGS (default location /home/oracle/<DDC>/)
    For a list of system requirements:
    System Requirements 

Target (APPLY) Server

Assumption is that Oracle database is installed, up and running and has a sys/system user. Also a tablespace will need to be created. Note that in this guide the the Apply server is an Oracle Linux EC2 Instance in AWS. Note that the example initial export dump and import (instantiation) of the source data into the target will be performed from the source database server using Oracle Datapump over a database link.  'Regular' export/import may also be done. Before starting with the Dbvisit Replicate configuration it is recommended to make sure you have the following information ready with regards to the Apply server and process:

  • EC2 - Server Name
  • Server IP Address (This will be the public DNS on EC2)
  • root (Unix User) password
  • oracle (Unix User) password  
  • Target Database Name (Amazon AWS EC2 instance)
  • Target TNS Alias (Make sure it is located in local tnsnames.ora) also have the full path ready
  • SYS password
  • SYSTEM password    
  • Sufficient disk space to store Dbvisit Replicate Apply PLOGS (default location /home/oracle/<DDC>/)
    For a list of system requirements:
    System Requirements 

 

 

SOURCE TNSNAMES.ora

SOURCE_DB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = sourceserver.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = SOURCE_DB)
    )
  )

EC2_TARGET =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = ec2-54-82-3-111.compute-1.amazonaws.com )(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = EC2_TARGET)
    )
  )

 

 

 Amazon EC2 Instances (Apply)

  The Source database is  on-premise. The EC2 target instance (EC2_TARGET) will be configured to perform the APPLY inside the AWS environment. 

 


Instance 1:SOURCE_DB  SOURCE

Environment Summary:

  • Oracle Enterprise  11.2.0.4
  • Database in archivelog mode
  • Database called “SOURCE_DB” created
  • Dbvisit Replicate 2.6.0.1 installed.


Instance 2: EC2_TARGET  TARGET

Environment Summary:

  • Oracle 11.2.0.2 (XE) installed
  • Database called "EC2_TARGET" created
  • Install Dbvisit Replicate 2.6.01 installed

 

TNSNAMES.ora on the EC2_TARGET

SOURCE_DB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = sourceserver.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = SOURCE_DB)
    )
  )


EC2_TARGET =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = ec2-54-82-3-111.compute-1.amazonaws.com )(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = EC2_TARGET)
    )
  )

 

Ensure the firewall on both environments (IPTABLES) as well as the AWS security groups is configures to allow communication between these systems.  Example:

root@dbvrds01:[/root] # cd /etc/sysconfig


root@dbvrds01:[/etc/sysconfig] # cat iptables
# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.

Ensure you have configured Security Group to allow the Replicate ports (7901-7904, 1521):

 

Dbvisit Replicate Installation/Configuration

Installing latest Dbvisit Replicate on the source on premise machine and the target EC2 instance:

 

root@akl:[/root] # rpm -ivh dbvisit_replicate-2.6.01-1.x86_64.rpm
Preparing...                ########################################### [100%]
   1:dbvisit_replicate      ########################################### [100%]

 

Please note that the main configuration (Setup Wizard) will be executed from the source (Mine) server which is also the same server hosting the source data we want to replicate to EC2.

Starting the Dbvisit Replicate Configuration

Execute “dbvrep” as the Oracle Unix account on the source server

 

[oracle ~]$ dbvrep
Initializing......done
Dbvisit Replicate version 2.6.01.
Copyright (C) Dbvisit Software Limited.  All rights reserved.
No DDC file loaded.
Run "setup wizard" to start the configuration wizard or try "help" to see all commands available.

 

Once the command line interface (dbvrep) starts, type in “setup wizard” to start the configuration process (below is an example):

 

Run "setup wizard" to start the configuration
wizard or try "help" to see all commands available.

dbvrep> setup wizard

This wizard configures Dbvisit Replicate.
The setup wizard creates configuration scripts, which need
to be run after the wizard ends. No changes to the databases are made before
that.
The progress is saved every time a list of databases,
replications, etc. is shown. It will be re-read if wizard is restarted and the
same DDC name and script path is selected.

Run the wizard now? [yes]

Accept end-user license agreement? (view/yes/no) [view] yes

Before starting the actual configuration, some basic
information is needed. The DDC name and script path determines where all files
created by the wizard go (and where to reread them if wizard is
rerun) and the license key determines which options are
available for this configuration.

(DDC_NAME) - Please enter a name for this replication
(suggestion: use the name of the source database): [] TEST-EC2

(LICENSE_KEY) - Please enter your license key: [(trial)]

Which Replicate edition do you want to trial (LTD/XTD/MAX):[MAX]

(SETUP_SCRIPT_PATH) - Please enter a directory for location
of configuration scripts on this machine: [/home/oracle/TEST-EC2] /home/oracle/TEST


Network configuration files were detected on this system in
these locations:

/u01/app/oracle/product/11.2.0/db_1/network/admin
/u01/app/oracle/product/10.2.0/db_1/network/admin
/u01/app/oracle/product/11.2.0/db_1/network/admin

(TNS_ADMIN) - Please enter TNS configuration directory for
this machine: [/u01/app/oracle/product/11.2.0/db_1/network/admin]

Step 1 - Describe databases
========================================
The first step is to describe databases used in the
replication. There are usually two of them (source and target).
Store SYSDBA and DBA passwords? Passwords only required
during setup and initialization? (yes/no) [yes]
Let's configure the database, describing it's type,
connectivity, user names etc.

What type of database is this? (Oracle/MySQL/SQL
Server/Oracle AWS RDS/CSV/Hadoop): [Oracle]

Please enter database TNS alias: [] SOURCE_DB

Please enter SYSDBA user name: [SYS]
Please enter password for this user: [change_on_install] ******
Please enter user with DBA role: [SYSTEM]
Please enter password for this user: [manager] ******

Connecting to database SOURCE_DB as SYSTEM to query list of
tablespaces and to detect ASM (by looking whether any redo logs or archived
logs are stored in ASM).

Enter the Dbvisit Replicate owner (this user will be created
by this script): [dbvrep]
Please enter password for this user: [dbvpasswd]

Permanent tablespaces detected on the database: USERS.
Please enter default permanent tablespace for this user:[USERS]

Temporary tablespaces detected on the database: TEMP.
Please enter default temporary tablespace for this user:[TEMP]

Following databases are now configured:
1: Oracle DZ11G, SYS/***, SYSTEM/***, dbvrep/***,
USERS/TEMP, dbvrep/, ASM:NO, TZ: +00:00

Enter the number of the database to modify it, or
"add", or "done": [add]

Let's configure the database, describing it's type,
connectivity, user names etc.

What type of database is this? (Oracle/MySQL/SQL
Server/Oracle AWS RDS/CSV/Hadoop): [Oracle]
Please enter database TNS alias: [] EC2_TARGET
Please enter SYSDBA user name: [SYS]
Please enter password for this user: [change_on_install] *******
Please enter user with DBA role: [SYSTEM]
Please enter password for this user: [manager] **********

Connecting to database EC2_TARGET as SYSTEM to query list of
tablespaces and to detect ASM (by looking whether any redo logs or archived
logs are stored in ASM).

Enter the Dbvisit Replicate owner (this user will be created
by this script): [dbvrep]
Please enter password for this user: [dbvpasswd]
 
Permanent tablespaces detected on the database: USERS.
Please enter default permanent tablespace for this user: [USERS]
Temporary tablespaces detected on the database: TEMP.
Please enter default temporary tablespace for this user: [TEMP]

Following databases are now configured:
1: Oracle SOURCE_DB, SYS/***, SYSTEM/***, dbvrep/***,
USERS/TEMP, dbvrep/, ASM:NO, TZ: +00:00
2: Oracle EC2_TARGET, SYS/***, SYSTEM/***, dbvrep/***, USERS/TEMP,
dbvrep/***, ASM:NO, TZ: +00:00


Enter the number of the database to modify it, or "add", or "done": [done]

Step 2 - Replication pairs
========================================
The second step is to set source and targets for each
replication pair.

Let's configure the replication pair, selecting source and
target.

Following databases are described:
1: SOURCE_DB (Oracle)
2: EC2_TARGET (Oracle)

Select source database: [1]
Select target database: [2]
Will be DDL replication enabled? [yes]
Use fetcher to offload the mining to a different server?
(yes/no) [no]

Would you like to encrypt the data across the network (yes
or no) [no]
Would you like to compress the data across the network (yes
or no) [no]
How long do you want to set the network timeouts.
Recommended range between 60-300 seconds [60]

Lock and copy the data initially one-by-one or at a single SCN?

one-by-one : Lock tables one by one and capture SCN
single-scn : One SCN for all tables
ddl-only   : Only DDL
script for target objects
resetlogs  : Use SCN
from last resetlogs operation (standby activation, rman incomplete
recovery)                                                                                                        
(one-by-one/single-scn/ddl-only/resetlogs) [single-scn]

What data instantiation script to create?
dp_networklink : Data Pump with network link. No export
datafile is created (APPLY.sh)
dp_exp         : Data Pump with export datafile. Creates an export datafile (APPLY.sh)
exp            : Pre-datapump exp/imp with export datafile (APPLY.sh)
ddl_file       : DDL file created (APPLY.sql)
ddl_run        : DDL is automatically executed on target
load           : All replicated data is created and loaded automatically
none                                                                                                              
(dp_networklink/dp_exp/exp/ddl_file/ddl_run/load/none) [dp_networklink]
Following replication pairs are now configured:

1: SOURCE_DB (Oracle) ==> EC2_TARGET (Oracle), DDL: yes, fetcher: no,
process suffix: (no suffix), compression: no, encryption: no, network timeout:
60, prepare type: single-scn, data load: dp_networklink

Enter number of replication pair to modify it, or
"add", or "done": [done]

Step 3 - Replicated tables
========================================
The third step is to choose the schemas and tables to be
replicated. If the databases are reachable, the tables are checked for
existence, datatype support, etc., schemas are queried for tables. Note
that all messages are merely hints/warnings and may be
ignored if issues are rectified before the scripts are actually executed.
 
Following tables are defined for replication pairs:
1: SOURCE_DB (Oracle) ==> EC2_TARGET (Oracle), DDL: yes, suffix: (no suffix), prepare: single-scn
  No tables defined.

Enter number of replication pair to modify it, or
"done": [1]
Please enter list of all individual tables to be replicated.
Enter schema name(s) only to replicate all tables in that schema. Use comma or
space to delimit the entries.
Enter the tables and schemas: [] SCOTT
Add more tables or schemas? (YES/NO) [NO] NO

To replicate changes of PL/SQL objects in schema(s), please
enter the schemas to be replicated. Note that specifying any entry will cause
additional privileges to be granted to dbvrep. Enter through a
comma or space-delimited list.

Enter the list of schemas (PL/SQL): []

You can also specify some advanced options:

1. Rename schemas or tables.

2. Specify filtering conditions.

3. (Tables only) Configure Change Data Capture; this does
not maintain a copy of the source table, but logs all operations as separate
entries. This is useful for ETL or as an audit trail. This usually
requires adding of new columns (timestamps, old/new values
etc.) to the target table.

Specify rename name or filter condition for any of the
specified schemas (YES/NO): [no]

Following tables are defined for replication pairs:
1: SOURCE_DB (Oracle) ==> EC2_TARGET (Oracle), DDL: yes, suffix: (no
suffix), prepare: single-scn  SCOTT(tables)

Enter number of replication pair to modify it, or "done": [done]

Step 4 - Process configuration
========================================
The fourth step is to configure the replication processes
for each replication.

Following processes are defined:

1: MINE on SOURCE_DB
  Not configured.
2: APPLY on EC2_TARGET
  Not configured.


Enter number of process to modify it, or "done": [1]
Fully qualified name of the server for the process (usually
co-located with the database, unless mine is offloaded using fetcher):[sourceserver.com]

Server type (Windows/Linux/Unix): [Linux]
Enable email notifications about problems (yes/no)? [no]
Enable SNMP traps/notifications about problems (yes/no)?[no]

Directory with DDC file and default where to create log
files etc. (recommended: same as global setting, if possible)? [/home/oracle/TEST]

Review APPLY DDC file

Ensure you have the correct TNS_ADMIN details in the APPLY ddc file.  In this test example environment Oracle Express is used on the APPLY server.  The location of the TNS_ADMIN variable in the TEST-EC2-APPLY.ddc is:

 

memory_set TNS_ADMIN /u01/app/oracle/product/11.2.0/xe/network/admin

 

Execute TEST-EC2-all.sh script on sourceserver.com

Run the TEST-EC2-all.sh script to initialize Dbvisit Replicate and load the dbvrep repository in both the source and target.  It is important that the steps above be executed before running this step.

These steps are required after the TEST-EC2-all.sh script runs:

1) Create the necessary directory(ies) on the servers:
ec2-54-82-3-111.compute-1.amazonaws.com: /home/oracle/TEST

2) Copy the DDC files to the server(s) where the processes will run:
ec2-54-82-3-111.compute-1.amazonaws.com: /home/oracle/TESTC/TEST-EC2-APPLY.ddc
sourceserver.com: /home/oracle/TEST/TEST-EC2-MINE.ddc

3) Review that path to dbvrep executable is correct in the run scripts:
/home/oracle/TEST/TEST-EC2-run-sourceserver.sh
/home/oracle/TEST/TEST-EC2-run-ec2-54-82-3-111.compute-1.amazonaws.com.sh

4) Copy the run script to the server(s) where the processes will run:
sourceserver.com: /home/oracle/TEST/TEST-EC2-run-dbvrds01.sh
ec2-54-82-3-111.compute-1.amazonaws.com: /home/oracle/TEST/TEST-EC2-run-ec2-54-82-3-111.compute-1.amazonaws.com.sh

5) Ensure firewall is open for listen interfaces 0.0.0.0:7902, 0.0.0.0:7901 used by the processes.

6) Make sure the data on apply are in sync as of time when setup was run.
Scripts for Data Pump/export/DDL were created as requested:
/home/oracle/TEST/APPLY.sh
Create referenced database links (if any) before running the scripts.


7) Start the replication processes on all servers:
sourceserver.com: /home/oracle/TEST/TEST-EC2-run-sourceserver.com.sh
ec2-54-82-3-111.compute-1.amazonaws.com: /home/oracle/TEST/TEST-EC2-run-ec2-54-82-3-111.compute-1.amazonaws.com.sh

8) Start the console to monitor the progress:
/home/oracle/TEST/start-console.sh


The above list is stored in /home/oracle/TEST/Nextsteps.txt.

 

 

Once the above scripts are created, copy the TEST-EC2-ec2-54-82-3-111.compute-1.amazonaws.com.sh and TEST-EC2-APPLY.ddc to the ec2-54-82-3-111.compute-1.amazonaws.com server, as directed by the Nextsteps.txt document.  

[oracle@ ]$ scp /home/oracle/TEST/TEST-EC2-run-ec2-54-82-3-111.compute-1.amazonaws.com.sh ec2-54-82-3-111.compute-1.amazonaws.com:/home/oracle/TEST/


[oracle@ ]$ scp /home/oracle/TEST/TEST-EC2-APPLY.ddc ec2-54-82-3-111.compute-1.amazonaws.com:/home/oracle/TEST/

 

Instantiate Data (Import data into EC2)

 

The first step is to create the required database link.  This link is required to pull the data from the source database into the target database. .  For this database link the SYSTEM account is used.

 

SQL> create public database link XX connect to system identified by manager using '(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = SOURCESERVER.COM)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = SOURCE_DB)))';

Database link created.


SQL> select * from v$instance@SOURCE_DB;

Start the import process

 

To import the data into the EC2 database you will need to use Datapump using the database links.

 

The import script was created as part of the setup wizard process.  You will have a file called APPLY.sh located in the /home/oracle/TEST directory.  Edit this file and add the option “exclude=statistics” at the end.  This will ensure you do not get any errors at the end of the import process.  Once you have updated the file and as per the above instructions you have your database links in place you can execute the script from the sourceserver.com server.

 

[oracle\]$ cat APPLY.sh

Starting the Dbvisit Replicate console

 

The console can be started from the Mine server (source) using the “start-console.sh” script

 

[oracle@ ]$ ./start-console.sh

 

Example output can be seen below.  Note that the mine and apply process does take some time to initialize.

 

Once both Mine and Apply is initialized:
 

\ Dbvisit Replicate 2.6.01.3880(MAX edition) - Evaluation License expires in 30 days

MINE IS running. Currently at plog 141 and SCN 4587877 (03/12/2014 05:36:19).

APPLY IS running. Currently at plog 141 and SCN 4587867 (03/12/2014 05:36:17).
