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 = awsdb.cu1fmi2nxxxx.us-east-1.amazonaws.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = EC2_TARGET)
    )
  )

 

 

 

Creating Amazon EC2 Instances (Apply)

In this example we created one AWS EC2 instance to show the concept of loading data into EC2 using Replicate.  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 Called “SOURCE_DB” created
  • Database in archivelog mode
  • Dbvisit Replicate 2.6.0.1 installed.


Instance 2: EC2_TARGET  TARGET

Environment Summary:

  • EC2 instance running Oracle Linux 6.3
  • Install Dbvisit Replicate 2.6.01 installed.
  • Oracle 11.2.0.2 (XE) installed
  • Database called (EC2_TARGET) created

 

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 = awsdb.cu1fmi2xxxx.us-east-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.
*filter

-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited
COMMIT


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 from 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) started, type in “setup wizard” to start the configuration process (below is an example):

 

oracle@[/home/oracle/TEST]: dbvrep


Initializing......done


Dbvisit Replicate version 2.6.01.3880


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.


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): [] DZ11G


(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/DZ11G]
/home/oracle/SOURCE_DB


 


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: [] DZ11G


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 DZ11G 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: [] XE


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 XE as SYSTEM to query list of
tablespaces and to detect ASM (by looking whether 


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


2: Oracle XE, 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: DZ11G (Oracle)


2: XE (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: DZ11G (Oracle) ==> XE (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: DZ11G (Oracle) ==> XE (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: DZ11G (Oracle) ==> XE (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 DZ11G


  Not configured.


2: APPLY on XE


  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):
[dbvlin210.dbvisit.co.nz]


Server type (Windows/Linux/Unix): [Linux]


Enable email notifications about problems (yes/no)? [no]


Enable SNMP traps/notifications about problems (yes/no)?
[no]

These steps are required after the DZ11G-all.sh script runs:


 


1) Create the necessary directory(ies) on the servers:


ec2-54-82-3-191.compute-1.amazonaws.com:
/home/oracle/SOURCE_DB


 


2) Copy the DDC files to the server(s) where the processes
will run:


ec2-54-82-3-191.compute-1.amazonaws.com:
/home/oracle/SOURCE_DB/DZ11G-APPLY.ddc


dbvlin210.dbvisit.co.nz:
/home/oracle/SOURCE_DB/DZ11G-MINE.ddc


 


3) Review that path to dbvrep executable is correct in the
run scripts:


/home/oracle/SOURCE_DB/DZ11G-run-dbvlin210.dbvisit.co.nz.sh


/home/oracle/SOURCE_DB/DZ11G-run-ec2-54-82-3-191.compute-1.amazonaws.com.sh


 


4) Copy the run script to the server(s) where the processes
will run:


dbvlin210.dbvisit.co.nz:
/home/oracle/SOURCE_DB/DZ11G-run-dbvlin210.dbvisit.co.nz.sh


ec2-54-82-3-191.compute-1.amazonaws.com:
/home/oracle/SOURCE_DB/DZ11G-run-ec2-54-82-3-191.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/SOURCE_DB/APPLY.sh


Create referenced database links (if any) before running the
scripts.


 


7) Start the replication processes on all servers:


dbvlin210.dbvisit.co.nz:
/home/oracle/SOURCE_DB/DZ11G-run-dbvlin210.dbvisit.co.nz.sh


ec2-54-82-3-191.compute-1.amazonaws.com:
/home/oracle/SOURCE_DB/DZ11G-run-ec2-54-82-3-191.compute-1.amazonaws.com.sh


 


8) Start the console to monitor the progress:


/home/oracle/SOURCE_DB/start-console.sh

dbvrep> setup wizard
This wizard configures Dbvisit Replicate to start a replication process.


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): [] RDSPOC
(LICENSE_KEY) - Please enter your license key (or just enter "(trial)"): [(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/RDSPOC]


Network configuration files were detected on this system in these locations:
/u01/app/oracle/product/11.2.0/xe/network/admin
(TNS_ADMIN) - Please enter TNS configuration directory for this machine: [/u01/app/oracle/product/11.2.0/xe/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); however, there can be just one (when
source and target is the same) or more than two (one-to-many or other complex configurations.)
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]
Please enter database TNS alias: [] XE
Please enter SYSDBA user name: [SYS]
Please enter password for this user: [change_on_install] <<- Test system is using default passwords
Please enter user with DBA role: [SYSTEM]
Please enter password for this user: [manager]


Connecting to database XE 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 and apply user (this user will be created by this script): [dbvrep]
Please enter password for this user: [dbvpasswd]


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


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


Following databases are now configured:
1: Oracle XE, SYS/***, SYSTEM/***, dbvrep/***, USERS/TEMP, dbvrep/, ASM:NO, TZ: +00:00
Enter number of 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]
Please enter database TNS alias: [] AWSDB
Please enter SYSDBA user name: [SYS] dbvadmin  <<- Specify AWS RDS instance DBA user Account
Please enter password for this user: [change_on_install] ********
Please enter user with DBA role: [SYSTEM] dbvadmin <<- Specify AWS RDS instance DBA user Account
Please enter password for this user: [manager] ********


Connecting to database AWSDB as dbvadmin 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 and apply user (this user will be created by this script): [dbvrep]
Please enter password for this user: [dbvpasswd]


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


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


Following databases are now configured:
1: Oracle XE, SYS/***, SYSTEM/***, dbvrep/***, USERS/TEMP, dbvrep/, ASM:NO, TZ: +00:00
2: Oracle AWSDB, dbvadmin/***, dbvadmin/***, dbvrep/***, USERS/TEMP, dbvrep/, ASM:NO, TZ: +00:00
Enter number of 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. This is usually just choosing the first database as source and the second one as
target, but many more configurations are possible.
Let's configure the replication pair, selecting source and target.
Following databases are described:
1: XE (Oracle)
2: AWSDB (Oracle)
Select source database: [1]
Select target database: [2]
Will be DDL replication enabled? (If YES, the script will grant more privileges to the Dbvisit Replicate users and enable database-wide supplemental        logging): [yes]
Use fetcher to offload the mining to a different server? (yes/no) [no] NO
(NETWORK_QUALITY) - Please specify your network type (LAN or WAN). Autoconfigures timeouts, use of compression etc. [LAN] WAN
Lock and copy the data initially one-by-one or at a single SCN? (one-by-one/single-scn/ddl-only/resetlogs) [single-scn] single-scn
What data copy script to create? (dp_networklink/dp_exp/exp/ddl_file/ddl_run/load/none) [dp_networklink] dp_networklink


Following replication pairs are now configured:
1: XE (Oracle) ==> AWSDB (Oracle), DDL: yes, fetcher: NO, process suffix: (no suffix), network: WAN, 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.


Note the following assumptions are made in this wizard – which can be modified by editing the resulting script:
1. All replicated tables have a primary key defined.
2. All columns of the tables and all tables of the specified schemas are replicated, and if DDL support is enabled, whenever a new column/table is added,
this should be replicate as well.
3. If an apply conflict arises, the default option is to try again repeatedly, until a different option is given or the underlying issue is resolved.
4. If an apply conflict arises, no more data will be replicated until the issue is resolved or ignored.


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. Dbvisit Replicate
can create the target table with the additional columns during setup by selecting "ddl_run" in the data copy section of Step 2.


Following tables are defined for replication pairs:
1: XE (Oracle) ==> AWSDB (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: [] OE
Selected schemas: OE
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): []
Specify rename name or filter condition for any of the specified schemas (YES/NO): [no]


Following tables are defined for replication pairs:
1: XE (Oracle) ==> AWSDB (Oracle), DDL: yes, suffix: (no suffix), prepare: single-scn
  OE(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. Although most options have reasonable defaults, manual input is required.


Following processes are defined:
1: MINE on XE
  Not configured.
2: APPLY on AWSDB
  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): [dbvrds01]
Server type (Windows/Linux/Unix): [Linux]
Enable email notifications about problems (yes/no)? [YES] NO
Enable SNMP traps/notifications about problems (yes/no)? [NO] NO
Directory with DDC file and default where to create log files etc. (recommended: same as global setting, if possible)? [/home/oracle/RDSPOC]

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 RDSPOC-APPLY.ddc is:

 

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

 

Execute prod-all.sh script on dbvrdsrep01

Run the RDSPOC-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.

OK-0: Completed, but some operation(s) raised warnings and/or errors.
These steps are required after the RDSPOC-all.sh script runs:


1) Create the necessary directory(ies) on the servers:
dbvrds02: /home/oracle/RDSPOC


2) Copy the DDC files to the server(s) where the processes will run:
dbvrds02: /home/oracle/RDSPOC/RDSPOC-APPLY.ddc
dbvrds01: /home/oracle/RDSPOC/RDSPOC-MINE.ddc


3) Review that path to dbvrep executable is correct in the run scripts:
/home/oracle/RDSPOC/RDSPOC-run-dbvrds01.sh
/home/oracle/RDSPOC/RDSPOC-run-dbvrds02.sh


4) Copy the run script to the server(s) where the processes will run:
dbvrds01: /home/oracle/RDSPOC/RDSPOC-run-dbvrds01.sh
dbvrds02: /home/oracle/RDSPOC/RDSPOC-run-dbvrds02.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/RDSPOC/APPLY.sh
Create referenced database links (if any) before running the scripts.


7) Start the replication processes on all servers:
dbvrds01: /home/oracle/RDSPOC/RDSPOC-run-dbvrds01.sh
dbvrds02: /home/oracle/RDSPOC/RDSPOC-run-dbvrds02.sh


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


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

 

 

Once the above scripts are created, copy the RDSPOC-rundbvrds02.sh and RDSPOC-APPLY.ddc to the dbvrds02 server, example:

 

[oracle@dbvrds01 RDSPOC]$ scp /home/oracle/RDSPOC/RDSPOC-run-dbvrds02.sh dbvrds02:/home/oracle/RDSPOC/


[oracle@dbvrds01 RDSPOC]$ scp /home/oracle/RDSPOC/RDSPOC-APPLY.ddc dbvrds02:/home/oracle/RDSPOC/

 

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 AWSDB database into the XE database.  The full network connection description is used for the connection detail, as we do not have access to the local system to modify the tnsnames.ora.  For this database link the SYSTEM account is used.

 

SQL> create public database link XE connect to system identified by manager using '(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.85.90.146)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = XE)))';

Database link created.


SQL> select * from v$instance@xe;

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/RDSPOC 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 dbvrdsrep01 server.

 

[oracle@dbvrds01 RDSPOC]$ 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@dbvrds01 RDSPOC]$ ./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:

Testing the replication

 

The next step is to generate some load on the XE database using swingbench.  This can be done using the generate_load script.  To see the status of the replicate you can open a second terminal and open the replicate console with “start-console.sh”.    Example:

While the above is running you can open the Dbvisit Replicate console and you can see the progress of the replication:
