GoldenGate for NonStop SQL/MP to SQL

GoldenGate for NonStop SQL/MP to SQL Server


Objective

Upon completion of this lesson, you will be able to keep two heterogeneous databases

synchronized, in this case NonStop audited SQL/MP to Microsoft SQL Server.

During this lesson, you will learn how to:

Prepare your environment to configure the GoldenGate processes

Configure and execute the initial data load

Configure and start the change capture of database operations

Configure and start the change delivery of database operations

NonStop Audited to MS SQL Server configuration

Overview of Tasks

Prepare the Environment

In order to execute this lesson, the GoldenGate application must be installed on both the

source and target systems. The installation includes a sample database and scripts to generate

initial data as well as subsequent update operations. The source and target tables are created

and loaded with initial data. The GoldenGate Manager processes are also started so that other

processes may be configured and started.

Initial Data Load

To initially load data between heterogeneous databases, use the GoldenGate application to

perform your initial data synchronization while the application remains active. This lesson

demonstrates using Extract to pull data from the source files and sending the data directly to

Replicat on the target system.

Configure Change Capture

For audited tables, the Extract process is configured to capture change data directly from the

TMF audit trails and store the changes in a data queue known as GoldenGate remote trails.

Configure Change Delivery

Once the tables have been initially loaded with data and the Extract process is capturing all

operations, the Replicat process is configured to deliver the captured operations to the target

database.

Exercise 1.


Objective

The goals of this exercise are to:

Configure and start the Manager processes.

Prepare the source and target sample databases.

Generate a data definition and copy it to the source system.

Prepare the source NSK environment

1. Configure a GLOBALS parameter file on the source

Execute the following commands on the <source> system.

A GLOBALS parameter can be used to uniquely identify each GoldenGate instance when

multiple environments exist on single NSK node. Use the two-character <prefix> that was

defined in the Lab Preparation.

Execute the following commands on the <source> system unless a <prefix> is not needed for

your installation.

TACL> VOLUME <install vol>.<install subvol>

TACL> TEDIT GLOBALS

ADD DEFINE =GGS_PREFIX, CLASS MAP, FILE $<prefix>

2. Configure the Manager process on the source system


The Manager process is responsible for starting and monitoring all of the other GoldenGate

processes. You will always have one manager process per GoldenGate instance.


TACL> RUN GGSCI

GGSCI> TEDIT PARAMS MGRPARM

-- GoldenGate Manager Parameter file

TCPIPPROCESSNAME <tcpip process>

PORT <port>

GGSCI> START MANAGER, CPU 1, PRI 180


Verify the results:

GGSCI> INFO MANAGER

3. Create and load source files


The installation includes scripts to create sample tables and generate initial data. Note that

your <prefix> may need to be substituted for the GG in subvolumes GGSSOU and GGSDEF

used in this section.

TACL> SQLCI

>> VOLUME <install vol>.GGSSOU;

>> CREATE CATALOG;

>> OBEY <install vol>.<install subvol>.DEMOSQL;

>> OBEY <install vol>.<install subvol>.DEMOLDS (INITIAL);

Verify the results:

>> SELECT * FROM TCUSTMER;


4. Generate source definitions


The DEFGEN utility is an interactive program that generates a source definition file describing

the layouts of the files/tables that are to be replicated.


TACL> RUN DEFGEN

Within DEFGEN, the following prompts and replies are issued:

Enter definitions filename (or Exit): <install vol>.GGSDEF.TCUSTDEF

File/Table to create definition for (or Exit): <install vol>.GGSSOU.TCUSTMER

Definition retrieved.

File/Table to create definition for (or Exit): <install vol>.GGSSOU.TCUSTORD


File/Table to create definition for (or Exit): EXIT

5. Move the source definitions to the target

After exiting, FTP the file <install-vol>.GGSDEF.TCUSTDEF in ASCII format to the target

<install location>/dirdef/source.def.

6. Generate target database scripts based on your source layouts


The DDLGEN utility is an interactive program that generates a script containing table create

statements for your target database based on the layouts of your source files/tables.



TACL> RUN DDLGEN

This initiates an interactive DDLGEN session with the prompts and replies listed below. Select

the appropriate template name for your database from the table below.

DDLGEN prompts:

Enter definitions filename (or Exit): <install vol>.GGSDEF.TCUSTSQL

DDL template file name (or Exit): <template name>

File/Table to create definition for (or Exit): <install vol>.GGSSOU.TCUSTORD


File/Table to create definition for (or Exit): <install vol>.GGSSOU.TCUSTMER

Definition retrieved

File/Table to create definition for (or Exit): EXIT

Template names:

TMPLDB2 DB2 for Windows and UNIX

TMPLDB2M DB2 for the z/OS and OS/39

TMPLMSS MS SQL Server

TMPLORA Oracle

TMPLSYB Sybase

TMPLTDM NonStop SQL/MP

7. Move the scripts

After exiting, FTP the file <install-vol>.GGSDEF.TCUSTSQL in ASCII format to the target file <install location>/dirsql/tcust.sql.

Prepare the SQL Server 2005 target system

Install Manager

1. Configure Manager process on the target

Execute the following commands on the <target> system.

Note! The port numbers must be unique if you are installing GoldenGate more than once on

the same server.

Shell> cd <install location>

Shell> ggsci


GGSCI> EDIT PARAMS MGR

In the parameter file, enter the following parameter, then save and close the file.

-- GoldenGate Manager Parameter file

PORT <port>

Start Manager.

GGSCI> START MANAGER

Verify the results:

GGSCI> INFO MANAGER

Steps to create the database

2. Create the database

From Start>Programs, run SQL Server Management Studio.

Enter the name of the local SQL Server instance, then click connect.

Note: These instructions assume SQL Server Authentication which requires the

more complex, double layer, of authentication. For only Windows Authentication,

you can leave out most of the login and password entries.

This displays the main SQL Server Management Studio dialog box. Right, right-click Database and select the New Database option.


The New Database dialog box appears. In the Name box, type the <database> from

the Lab Preparation worksheet.

Click OK to add the database.

The main SQL Server Management Studio dialog box reappears.

3. Create SQL Server logins and users

Right-click Security and select the New > Login.


The New Login dialog box appears.

For Name, type the <login>.

Select Authentication,

If you selected SQL Server Authentication, type the <password> in the two

Password fields.

Under Defaults, select your <database> for Database, and leave Language set to the

default.


Do not click OK. Instead, from Select a page in the upper left-hand box, double click User Mapping.

In the upper Users mapped to this login area, activate the checkmark next to your

database.

In the lower Database role membership for <database> area,, check the box for the

db_owner role.

Click OK to exit.

The next step creates a schema that you will associate with the new user.

While you have the database selected, click on the New Query button in the main

menu.

The right side of the dialog displays the SQL Query interface. Type in:

create schema <owner/schema>;


And press the Execute button from the toolbar.

Now you need to associate the new user and the schema that you have created with the new

database.

Right click on the Security option that is under the database and select New > User.

The New Database User dialog box appears. Enter the name of your user and press

the browse button labeled with three dots (…).


The Select Login dialog displays. Press the Browse button.

Select your new user <login> from the list. Then press OK.

Your selected user now displays in the object names box. Press OK to exit from

Select Login.

Back in the New Database User dialog, enter the <schema> you added as the default

schema and press OK.

4. Create the ODBC system data source name

The GoldenGate Extract process connects to a SQL Server database through an ODBC (Open

Database Connectivity) connection. Both the Extract and Replicat components of GoldenGate

require that a system data source name (DSN) be established, which stores the information

about how to connect to the SQL Server.

Click Start > Settings > Control Panel.

Double-click Administrative Tools.

Double-click Data Sources (ODBC) to open the ODBC Data Source Administrator

dialog box.

Click the System DSN tab, and then click the Add button. The Create New Data

Source dialog box appears.

Note: For SQL Server 2000, you may use any ODBC driver supported by the

database. For SQL Server 2005, however, you must use the ODBC driver that is

included with Microsoft Data Access Components (MDAC). Both Extract and

Replicat will abend if the SQL Native Client ODBC driver that is provided with SQL

Server 2005 is used.


Select the SQL Server driver and then click Finish. The Create a New Data Source

to SQL Server dialog box appears.

For Name, type <dsn>.

For a description, type "GG Training Data source" when creating this source DSN.

This field is optional.

For Which SQL Server do you want to connect to, select the server name.

Click Next.

Answer the question about how SQL Server should verify the login by selecting the

option that you entered when creating the <login>. Then type <login> in Login ID

and <password> in Password.


Click Next.

Make certain the default database is set to the database that you created; otherwise

select Change the default database to: and select it. Leave the other settings to their

defaults to use ANSI.

Click Next.

Leave the next dialog box set to the defaults, and click Finish.

In the confirmation, click Test Data Source to test the connection.

Close the confirmation dialog box and the Create a New Data Source box.


5. Create the practice tables


Go to SQL Server Management Studio, select your database and select New Query

from the toolbar.

If the correct database is not displayed in the drop down box (showing ggsdata

above), click on the arrow and select it from the list.

Click the File > Open and navigate to the demo_mss_create.sql script.

Click Open to open the script in the New Query window.

Execute the script by clicking the Execute Query button on the toolbar.

Verify the results using the following commands in the input window:

sp_help tcustmer

go

sp_help tcustord

go
