Tibco Database Adapter: Step By Step Tutorial

By | November 20, 2013

TIBCO database Adapters are used for enabling communication between TIBCO processes and database system. There are two types of services that can be used with a database adapter:

  • Publication Service

Adapter Publication service extracts data from the changed rows of a database table and publishes them on appropriate subject names which are then subscribed by adapter subscriber process starter.

  • Subscription Service

Subscription service of a database adapter does opposite to a publication service.  When running as a subscriber, database adapter listens on a subject, receives messages and updates the relevant tables in its associated database.

 

In this tutorial, we will be covering publication service of database adapter. If you are interested to know about TIBCO Adapter Subscription service, you can go to tutorial TIBCO Adapter: Step By Step Tutorial For Adapter Subscription Service

In this tutorial of Adapter Publication service, We will write a publication service that will look for any updates in a table TBL_EMPLOYEE in Oracle database and it will publish the updates on a subject. We will write a business process that will have Adapter Subscriber as start activity which will receive a message from the publication service of the specified adapter.

Step 1: Database Table Creation

Our adapter will be based on a table TBL_EMPLOYEE. We need to create the table using following query:

— Create table create table TBL_EMPLOYEE ( EMP_CODE        VARCHAR2(20) not null, EMP_NAME        VARCHAR2(30) not null, EMP_DESIGNATION VARCHAR2(30) not null, EMP_AGE         VARCHAR2(10) )

 

Step 2: Create database Adapter

In our project AdapterTest, we create a new Active Database Adapter Configuration by choosing Add Resources–>Active Database Adapter–>Active Database Adapter Configuration. We specify database driver, Schema name, IP, Port, User, Password etc. in Design-time connection tab for it. We need to use Test Connection button on the bottom to ensure that connection is fine with database.

 

adapter design time configuration

In Run-time Connection tab we need to specify ODBC DSN. ODBC DSN must be first created for this purpose. ODBC connection is created in Windows Environment in following way. Creating ODBC Connection for TIBCO adapter: Choose Start–>Control Panel–>Administrative Tools–>Data Sources (ODBC) in your windows machine.

ODBC

 

Under System DSN tab, create a new data source and name it TIBCO. Specify database parameters of your TIBCO database in required fields.

 

system DSN configuration

 

Using Test Connect button, test if your database connection is successful by giving database username and password.

 

test ODBC connection

 

If you have configured your ODBC connection correctly, you should get a message “Connection Established” as shown below:

connection successful

 

Now we have a working ODBC connection configured in our windows machine. So we can safely use this ODBC name in Run-time Connection tab of our adapter configuration.   Creating Adapter Publication Service: Now we need to add a publication service in our adapter. In “Adapter Services” folder, add a new publication services by choosing Add Resource–>Active Database Adapter–>Publication Service Configuration tab of publication service should be configured as shown below:

 

adapter service configuration

 

In the Table Tab of publication service configuration, choose the table TBL_EMPLOYEE by clicking on Add Table button. It will look as below after adding the table:

 

adapter service add table

 

In the publisher options tab, we have chosen Publish By Value as Storage Mode and Update as Update Mode. Note that we don’t create Publishing table. Its created automatically.

 

adapter publisher options setting

 

We don’t need to make any change in Advanced tab and it should look like this:

 

adapter service advanced setting

 

Now we are done with configuring our Adapter and making it ready.

Now is the time to move forward for crating a process for our adapter service.

 

Step 3: Create Adapter Subscriber Process

We create a process employeeSubscriber that will subscribe to the adapter we created in step 2. This process will have a Adapter Subscriber activity as its process starter. This process will write the information that it receives through adapter into a text file. Process will look like below:

 

employeeSubscriber process

 

In Adapter Subscriber Configuration tab, we choose our Adapter Service by using binocular. This will be the service for which this subscriber will be listening on a given subject.

adapter subscriber configuration

 

In Transport Tab of adapter subscriber, subject,  transport type etc. is specified. In this tutorial example, I have kept it to default without making any changes as shown below:

adapter subscriber transport

 

Adapter Subscriber Output tab shows the output of the subscriber activity. In body of its output, it will have all the columns of our publisher table as shown below:

adapter subscriber output tab

 

We use confirm activity after Adapter Subscriber to confirm the receipt of message. The Confirm activity confirms any confirmable messages received by the process instance. In configuration of confirm activity, we specify confirm event which is adapter subscriber in our case.

adapter subscriber confirm activity

We have used a Write File activity which will write Employee Details to a text file.

adapter subscriber write file activity

 

Now we are done with setting up all required bricks and blocks of our building and now is the time to test it.

 

Step 4: Test TIBCO database Adapter Publication Service

We have created one adapter publication service and one business process.  So we need to use both Adapter Tester and Process Tester for testing our code.

We can open Adapter Tester by going through Tools Menu in Tibco designer as shown below:

show adapter tester

 

After opening Adapter Tester, choose the adapter from the left side where all available adapter services are shown. Make sure that Working Directory points to the bin folder inside adapter installation path as shown below:

adapter tester

 

Using Start Buton, start the adapter. Once adapter is started, Start Button should change to Stop Button.

adapter tester started

 

Now our adapter is up and running. We need to start our process as well so that any messages received by Adapter go to its subscriber.

tester start process

Once we have our adapter as well as process ready in the tester, its time to play with our database table to fire the event.

We add a new record in the database table TBL_EMPLOYEE using below query:

INSERT INTO TBL_EMPLOYEE
VALUES
(800,’Ajmal Abbasi’,’Engineer’,26)

 

As soon as value is inserted in TBL_EMPLOYEE, it gets published to Publisher table P_TIBL_EMPLOYEE with ADB_L_DELIVERY_STATUS as ‘N’:

p_tbl_employee data with N status

Adapter Publication Service gets the information, process having adapter subscriber subscribes the request and process runs to its completion as shown below:

process tested in tester

 

Now, if we check the same record in the table P_TBL_EMPLOYEE, its ADB_L_DELIVERY_STATUS has changed to C (Complete):

p_tbl_employee data with C status

Now our last step in this tutorial is to check in the text file that we wrote in our process and verify that employee record has been written in the file:

file content written by write file activity

Congratulations, we are now done with our tutorial TIBCO Database Adapter: Step By Step

    Hello Sir,

    It is a very gud tutorial. Thanks for the tutorial.
    But i do have one query if two subscribers are UP in environment so what will be the condition of listening the Message.
    1:-Both will listen at same time.
    2:-Or there may be some condition.
    I actually want to know which one will listen first.

    Cool Tutorial
    I had a question–Is is possible to keep the Publishing table and the main table same ?
    If yes how can we do it ? I tried it but i got a config error not sure why.

    Thanks

      No Yash..You can’t keep both table same., Main table is parent table on which actual transaction will happnd.. On Main table you can apply triggers to get real time data.. Main table having authentication restrictions for actual transaction data.. Publishing table is TIBCO generated table.. This table required full authentication. Publishing table maintaining the state of actual table.. ADB runs on timer base activity which picking up data from publishing table untill “ADB_L_Delivery_status” values is C.. Even if any circumstances ADB adapter is down then also publishing table get the data from main table due to triggers.. So later on once ADB starts again all previous data will piched and processed.. Hope you doubts are clear..

    Hi Ajmal, Thanks much for this invaluable information. It worked just perfect.

    I faced a small error in between while starting up the adapter tester.

    DBError:5
    ErrorCode:HYC00
    ServerCode: 0
    Message:[Data Direct][ODBC Oracle Wire Protocol driver] optional feature not implemented.

    The resolution for this problem would be, while setting up the ODBC Sytem DSN, in the advanced tab, select the tick box: “Enable Timestamp With Timezone”

    Thanks again 🙂

    Hi Ajmal, Its a really helpful tutorial for the beginers. Some important steps I would like to include with your post. When we configuring ADB Adapters then we have one option “Save to Database” on design time configuration. Once we configure Adapter Properties (Publication/Subscription/Request-Reply) and save them then some inbuild commands of database are getting created with .Sql file in C:\tibco_home\Adapter\Adb\6.X\sql.. If DB user name has full access on DB then all command will executed in DB while checked “Save to Database” else we need to provide the SQL script file to DBA admin to execute the script.. If you open the script you will find create/alter commands for table, publication table, index, triggers. ADB adapter will only work if this script is properly deployed in Database.

      Hi Ajmal ji, Thank you…..!!! for this wonderful tutorial.

      Hi Kaushal, How the trigger can understand the data base events has been happened on source table and publish those changes/ updates to publishing table. Do we have to configure any thing on DBA or it happens by selecting the option “Save to Database”.

        Dear Dora,

        Thanks for the feedback.
        Please note that a trigger is automatically created on the source table which inserts records in the publishing table based on the DML operations happening on the source table.

    If for my source, I have one parent table(P1) and it has three child tables(C1,C2 and C3) and they have P_Id as a foreign key which is the primary key in the P1.
    If the data is inserted only in P1, and our publication service is triggered, how would the data be inserted in the Publishing table(P_P1)? Is the structure of the Pubishing table exactly the same as of our source table or only One publishing table is created including all the columns of P1,C1,C2,C3)? Please clarify.

      Hi Venkat, You can’t use views directly in adb adapters. Publication & subscription services can only configure with actual DB tables. Custom RPC is another option to call store procedures using request response service. You need to create store procedure to call view. Store procedure will return result of View on ADB Adapter. You have to call RPC services using invoke request response adapter palette activity.
      Hope this will help you.

    Hi,

    I’m facing problems when I try to update the AESchemas (if the schema of the table changes, for example) Is there any way to update the schemas automatically (as with R3 Adapter).

    Thanks

    Hi Guys. I need your help for configuring RPC services to call store procedure in ADB adapter. I have created one store procedure in SQL server and configure with ADB RR services (Custom Operation). I have call ADB RR service in request response adapter servies in TIBCO process. While passing data to adapter service, request get successes but record not updated in DB using store procedure. I m getting error in adapter log saying ‘Invalid column name ORDINAL_POSITION” with error code [RPC] AEADB-530010. I don’t have such column in DB table or store procedure. If I call same procedure using JDBC call Procedure I am able to update data in DB table without any error. Please guide for the same. It seems some adapter configuration issue as existing sample (with ADB adapter) also getting same error.

    Hi,

    We need to pick up only new values from db after adapter is deployed in environment. Is this possible. If yes please let us know configuration details.

    Hi,

    Please let me know how to fetch new records from database, after ADB is connected to database.
    I dont need to Re-Fetch all the data from the tables, but only the data which is Inserted,Deleted,Updated after the ADB is connected to Database.
