TIBCO BusinessWorks 6.0 release announcement

Details here – http://www.tibco.com/company/news/releases/2014/press1337.jsp

AN upcoming webinar which you can register – http://forms2.tibco.com/webinar-amx-bw6-q314.html?utm_medium=pr&utm_term=bw6pagepr&utm_content=textlink&utm_campaign=bw6apr14

It will use Eclipse IDE – this means more seamless usage of TFS via the eclipse-TFS plug in. It is a relief as I am not a big fan of the TFS integration capabilities of TIBCO BW Designer at this point.

TIBCO BusinessEvents 5.1 Studio– JMS Test connection failed

Just in case you are facing JMS Test connection failure issue even with the latest version of BusinessEvents (At this point I have version 5.1), follow the below steps :-

1) Copy the following jar files to the below location :-

jar files :-
jms.jar
tibjms.jar

Location where the JAR files need to be copied:-
%BE_HOME%/be/5.1/lib/ext/tpcl

Note – In my BE installation, I didn’t find the above jar files, I copied them from other TIBCO products installation folders.

2) Set the path in the studio.tra file :-
location of the Studio.tra file :-
%BE_HOME%\be\5.1\studio\eclipse\configuration\Studio.tra
Where the path needs to set:-

Look for the “studio.extended.classpath” in the studio.tra file and set the path for the jar files after the existing paths. Something like this (added line is highlighted in bold) :-

studio.extended.classpath=%BE_HOME%/hotfix/lib/ext/tpcl;%BE_HOME%/lib/ext/tpcl;%AS_HOME%/lib;
%HAWK_HOME%/lib
;%BE_HOME%/be/5.1/lib/ext/tpcl/jms.jar;%BE_HOME%/be/5.1/lib/ext/tpcl/tibjms.jar

I saw this issue in a Tibco BusinessWorks application using a SQL JDBC Driver 4.0 to connect to a SQL server 2008 R2 server. However, I believe that this could happen with any application written in Java/.NET using JDBC driver 4.0 connecting to SQL server 2008 R2 server.

:- Check If at least Microsoft® SQL Server® 2008 R2 Service Pack 2 is installed on the SQL server. If not, install it. If SP2 or Higher (e.g. SP3) is already installed and you still see the same issue – problem is something else.

Connect to the server from the SQL Management Studio and execute the below query :-

SELECT @@VERSION.
You should see the SP2 as…

TIBCO Cloud Bus – At a glance and more….

In the below screenshot, look at the URL closely and you will notice the highlighted Amazon AWS.
Yes – this is the TIBCO Classic Administrator hosted on TIBCO Cloud Bus which leverages Amazon Web Services for Its cloud computing platform. If this catches your attention – read on…..

image

TIBCO Cloud Bus is a subscription-based Integration Platform-as-a-Service (iPaaS). What? Another “As-A-Service” buzzword?  Simply put – iPaaS allows integration between cloud to cloud applications and also between cloud to on-premises applications. Cloud to on-premises application integration is important  because financial services companies which need to follow many security and regulatory compliances might need to keep some applications in house on as well as want to keep other applications hosted on TIBCO Cloud bus with seamless integration between on premises and cloud apps.

Hosting the apps on cloud means you don’t need your IT infrastructure team to set up an environment for you to deploy your application. In TIBCO cloud bus, you can provision your own TIBCO environment in really really short time before you quickly deploy your applications.
TIBCO Cloud bus can increase/decrease the number of machines that sit behind the services. It knows what the load on the application is and then automatically increase/decrease the horsepower required for the application.

For the connectivity from the TIBCO Cloud Bus to on premise TIBCO infrastructure , TIBCO Cloud Bus has to connect through VPN gateway from the public cloud to company’s datacenter. This would involve setting up VPN tunnel at company’s end which may involve company’s IT as well.

At the time of writing this, I have two areas to be research in TIBCO Cloud Bus. Will edit this post when I have done some more research – hopefully with some answers.
1) Cost Effectiveness
How cost effective is TIBCO Cloud bus VS on-premises TIBCO setup over a longer period of time? Why an organization won’t continue to grow on in-control on-premises infrastructure to host TIBCO services rather than using TIBCO cloud bus If it is not saving costs over a period of time. Need some case studies and statistics.

2) Security
How TIBCO Cloud Bus addresses the security concerns when It comes to hosting all the apps on the cloud OR integration between on-premises applications and cloud applications? Need some case studies.
 
All said and done, IMHO, we must acknowledge that cloud computing NOT just a buzzword anymore now. Its for real and here to stay. So when TIBCO, one of the leaders in integration and middleware industry has something to offer in this space, we just need to keep an eye on it – if not necessarily adopting the offering immediately.

If you are already bored of reading, try TIBCO Cloud Bus yourself (30 days trial) – If you need help in that, I have some help below. I have steps-by-step instructions on how to set up a TIBCO Cloud Bus environment below. Good Luck and Happy Learning!

Setting up a TIBCO Cloud Bus environment

Note :- For below steps,use Mozilla Firefox for browsing the Cloud Bus If you can. – I have seen issues in IE/Chrome.

1) Go to cloudbus.tibco.com.

clip_image010

2) Enter your TIBCO Access Point credentials. If you are not registered there, register at tap.tibco.com and use the same login and password here.

clip_image012

3) If you have the TIBCO BW installed in your machine. You already have the development environment and you can skip this step. If you don’t, you can download the installers. Click on Develop > TIBCO Cloud Bus Designer (Windows 64-bit) [If you have 64-bit windows installed]

clip_image016 
The TIBCO Cloud Business Designer has following in it.

clip_image018

a) Extract the zip file.
b) Open the silent file, Install-Designer.silent, in a text editor.
c) Review the license files in the license folder. If you accept the licenses, change the <acceptLicense> entry key to true in the silent file.
d) Change the <installPackageDirectory> entry key to your extracted temporary folder: C:\temp\TIB_tcb-designer_1.0.0_win_x86_64
e) Optionally update the values for the <installationRoot> and <environmentName> keys.
f) Save the silent file.
g) Run the installer: Install-Designer.cmd
h) After the installation is complete, start TIBCO Designer from the Windows Startup menu: Choose All Programs > TIBCO > Cloud Environment > TIBCO Designer 5.8.

4) Click on the deploy button to see the highlighted “Skyway” button.

clip_image020

5) Click on “Cloud Bus Starter Template” link to provision the BW, EMS and admin stack.

clip_image022

6) See more information on the stack we are going to provision

Unable to deploy Tibco BW application after configuring Tibco BW Process Monitor – ERROR – [TRA-000000] StreamGobbler(ERROR) : data = java.lang.NoClassDefFoundError: com/tibco/processmonitor/client/run Caused by: java.lang.ClassNotFoundException: com.tibco.processmonitor.client.run

As a part of Tibco BusinessWorks Process monitor, one needs to add following properties to the bwengine.tra file in the Tibco BusinessWorks machine.

#BW ProcessMonitor properties
java.start.class=com.tibco.processmonitor.client.run
tibco.clientVar.nJAMS/logMode=complete
tibco.clientVar.nJAMS/DataProvider/JMS/useJNDI=true
tibco.clientVar.nJAMS/DataProvider/JMS/useQueues=true
tibco.clientVar.nJAMS/DataProvider/JMS/destination=bwpm
tibco.clientVar.nJAMS/DataProvider/JMS/enabled=true
tibco.clientVar.nJAMS/DataProvider/JMS/user=admin
tibco.clientVar.nJAMS/DataProvider/JMS/password=
tibco.clientVar.nJAMS/DataProvider/JMS/server=tibjmsnaming\://My_EMS_IPAddress\:7222
tibco.clientVar.nJAMS/DataProvider/JMS/contextFactory=com.tibco.tibjms.naming.TibjmsInitialContextFactory
tibco.clientVar.nJAMS/DataProvider/JMS/connectionFactory=QueueConnectionFactory
tibco.clientVar.nJAMS/DataProvider/EngineLog/enabled=false

Added the above and after that I couldn’t deploy any BW application in our Tibco Administrator. The tsm.log showed the below error each time I attempted to deploy an application.

[TRA-000000] StreamGobbler(ERROR) : data = java.lang.NoClassDefFoundError: com/tibco/processmonitor/client/run Caused by: java.lang.ClassNotFoundException: com.tibco.processmonitor.client.run [TRA-000000] StreamGobbler(ERROR) : data = java.lang.NoClassDefFoundError: com/tibco/processmonitor/client/run Caused by: java.lang.ClassNotFoundException: com.tibco.processmonitor.client.run at java.net.URLClassLoader$1.run(Unknown Source)  at ava.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source)

The first line of the list of properties we added to the bwengine.tra has following :-
java.start.class=com.tibco.processmonitor.client.run
Of course – It was
bwengine was not to find that class. Started looking into which jar would contain this file and It turns out to be bwpm.jar which comes as a part of BWPM install package.

Adding that bwpm.jar to C:\tibco\bw\5.10\lib resolved the issue and I could deploy BW apps to BW classic admin without any issues.

How to check If at least SP2 is installed?
Connect to the server from the SQL Management Studio and execute the below query :-

SELECT @@VERSION.
You should see the SP2 as the part of result

image

Why :- See below :-
http://support.microsoft.com/kb/2653857
FIX: You cannot connect to SQL Server by using JDBC Driver for SQL Server after you upgrade to JRE 6 update 29 or a later version

What If you can not install SP2
We should always update latest service packs on the SQL server – not only for this issue. However, If you couldn’t and you had to live with current database server install – try using the below attribute in your TRA files.

java.property.TIBCO_SECURITY_VENDOR=j2se

If you are trying to test connection from the Tibco BusinessWorks Designer, add the above attribute in your <TIBCO_HOME>\designer\5.8\bin\designer.tra file.

If you want to deploy this change, add the above attribute in your <TIBCO_HOME>\domain\<Domain Name>\application\<Application>\<Application>.tra file and restart the service instances of the application.

NOTE:-
This same issue does not happen when you connect to Sql server 2005. That’s weird! Sounds like somebody broke something in Sql 2008 R2 and fixed it in SP2.

Sql Server job – Cannot insert the value NULL into column ‘owner_sid’, table ‘msdb.dbo.sysjobs’

I needed to script out a Sql job one Sql server (server1) and use the same script to create the same job on a different Sql server machine(server2). So, I scripted out the job from Server1 and ran the same on the Server2 and got the below error :-

Cannot insert the value NULL into column ‘owner_sid’, table ‘msdb.dbo.sysjobs’

Looking at more closely on the script, I noticed that the the script I created from the job on the Server1 also has the login which I used to login to Server1. This login is different from the one I was using to run the script on server2. See the highlighted login in the below screenshot.

image

Once I changed the script to put the login I am using to run the script on server2, the script ran fine and the job got created in the Server2.

Maximum connections exceeded!!!! – How to know who are logged on to a server and not letting you in?

We all hate to see this message when we want to login to the server :-
“The terminal server has exceeded the maximum number of allowed connections.”

image

All you need is the PsLoggedOn utility from sysInternals (now owned by Microsoft). Another reason we should all love Mark Russinovich and SysInternal tools.
Just follow the steps :-

  1. Download PSTools from here.
  2. Extract the zip file to a folder.
  3. Open command prompt and navigate to the extracted folder.
  4. Run the following command. Keep the \\ and replace the MachineName with the fully qualified name of the machine where you want to see who are currently logged on.

5.   You will see who are logged on to that machine.

psloggedon \\MachineName 

This saves you sending emails to a group to find out who are logged into the server. Rather – because you know who are logged in, you would ping/email those specific users, asking them to log off.

2013 in review

The WordPress.com stats helper monkeys prepared a 2013 annual report for this blog.

Here’s an excerpt:

The concert hall at the Sydney Opera House holds 2,700 people. This blog was viewed about 9,200 times in 2013. If it were a concert at Sydney Opera House, it would take about 3 sold-out performances for that many people to see it.

SQL Server–Change Data Capture [CDC] for “Watching” database tables for DML operations

In scenarios when we want to watch tables for any inserts, updates and deletes, we implement triggers. Triggers – not only needs database development effort and needs to be correctly written, It places locks on tables and slows things down.

In SQL Server 2008, Microsoft introduced a new capability called “Change Data Capture” [CDC] to watch and track changes on tables for any inserts, updates and deletes. This requires almost no database development effort and is more efficient than triggers. A very nice thing about CDC is that It makes use of transaction log which has all the data about any changes made to the database alreadySo why reinvent the wheel?

Basically, first you enable CDC on the database. Then enable CDC on the table (e.g. Account) you want to watch which will automatically create the a change tracking table (“Account_CT”) for the watched table. Any changes in your watched table (e.g. Account) will get recorded in the change tracking table (e.g Account_CT) and you can use the tracking table for all your queries.

“Talk is cheap. Show me the code.” – Linus Torvalds

1. Preparing sample data

/*Create sample database*/
USE [master]
GO
IF  EXISTS (SELECT name FROM sys.databases WHERE name = N’ChangeDataCaptureTest’)
DROP DATABASE [ChangeDataCaptureTest]
GO
/****** Object:  Database [ChangeDataCaptureTest]    Script Date: 10/23/2013 17:25:04 ******/
CREATE DATABASE [ChangeDataCaptureTest]

/*Create the sample table – This is the table we will be watching for inserts, updates and deletes*/
USE ChangeDataCaptureTest
GO
CREATE TABLE [Account]
(
    Id INT Primary Key IDENTITY(1,1),
    [Description] VARCHAR(500),
    [Active] BIT
)
GO


2. Enable CDC on the database

This looks scary, but all it is doing it is checking an already existing flag in sys.databases table in the master database. If you execute the following, you can see in which database CDC is currently enabled. In the below example, It is not enabled in any of the database:-
USE master
GO
SELECT [name], database_id, is_cdc_enabled 
FROM sys.databases      
GO    

image

Now we can enable CDC on our sample database.
USE ChangeDataCaptureTest
GO
EXEC sys.sp_cdc_enable_db
GO

If you execute the following, you can see the “is_cdc_enabled” column for our sample database is enabled:-
USE master
GO
SELECT [name], database_id, is_cdc_enabled
FROM sys.databases
GO

image


3. Enable CDC on the table you want to watch for Insert/Update/Delete

Now we need to enable the CDC on the table we want to watch.

USE ChangeDataCaptureTest
GO
EXEC sys.sp_cdc_enable_table
@source_schema = N’dbo’,
@source_name   = N’Account‘,
@role_name     = NULL
GO

When we execute the above, we see two Sql jobs created and started automatically.

image

image

cdc.ChangeDataCaptureTest_capture
This job watches the table “Accounts” and put changes in the tracking table Account_CT
cdc.ChangeDataCaptureTest_cleanup -
This job cleans up the tracking table Account_CT and can be scheduled as per the requirement.

At this point If we query the sys.tables :-
USE ChangeDataCaptureTest
GO
SELECT [name], is_tracked_by_cdc
FROM sys.tables
GO

image

4. Testing the results

Let us insert/update/delete data in the watched table [Account] and see the tracked changes in the [Account_CT] table.

Insert Operation
USE ChangeDataCaptureTest
GO
INSERT INTO Account
VALUES (‘Test’, 1)

Select to verify results
USE ChangeDataCaptureTest
GO
SELECT * FROM Account
GO
SELECT * FROM cdc.dbo_Account_CT
GO

image

Value for “__$operation” column is 2 indicates “Insert”. We can see the values in the columns “Description” and “Active”.

Update operation
USE ChangeDataCaptureTest
GO
UPDATE Account
SET Active= 0
WHERE Id = 1
Select to verify the results
USE ChangeDataCaptureTest
GO
SELECT * FROM Account
GO
SELECT * FROM cdc.dbo_Account_CT
GO

image
Value for “__$operation” column :-
3 = update (captured column values are those before the update operation).
4 = update (captured column values are those after the update operation)

DELETE Operations
USE ChangeDataCaptureTest
GO
DELETE Account
WHERE id = 1
Select to verify results
USE ChangeDataCaptureTest
GO
SELECT * FROM Account
GO
SELECT * FROM cdc.dbo_Account_CT
GO

image

Value for “__$operation” column is 2 indicates “Delete”.

Time based search on table changes
Need to see changes in a table based on given timestamp? No problem. When we enabled the table for change tracking, It also added a system table named “cdc.lsn_time_mapping” which has all the transaction with the timestamp.
Just join the change tracking table (Account_CT) with the system table “cdc.lsn_time_mapping” table on transaction id (start_lsn) and have the transaction filter criteria on the same.

image

USE ChangeDataCaptureTest
GO
SELECT B.*, A.tran_begin_time, A.tran_end_time 
FROM cdc.lsn_time_mapping A
INNER JOIN cdc.dbo_Account_CT B
ON A.start_lsn = B.__$start_lsn

image

Note :- In CDC, there’s no way to trace the user who causes each transaction.
