FlowLimit and MaxSessions

FlowLimit

FlowLimit value will limit the number of process starter creation no matter what is configured in the sessions of JMS Receiver

MaxSessions

A Session object is a single-threaded context for producing and consuming messages.

TestCase Number FlowLimit MaxSessions Result
1 5 1 Only one process instance will be crated
2 5 3 3 instances will be created and processed parallel.
3 5 6 5 instances will be created and processed parallel.

The best practice or suggestion is below:

  1. Create Max Session as per your requirement.
  2. Set the FlowLimit value greater than the Max Session

Setting flowlimit for a bwapplication in debugging mode.

-Dbw.application.job.flowlimit.<application name>.<application version> =<flowlimit value>

Eg: -Dbw.application.job.flowlimit.EMS.ACKMode.Tester.application.1.0=5

Setting max sessions for JMS Receive Message activity

Enable JMX on the AppNode

This post would explain what are the properties that need to be added to BW appnode to enable JMX.

From TIB_BW_performance_benchmarking_tuning https://docs.tibco.com/pub/activematrix_businessworks/6.3.4/doc/html/GUID-BAC813F8-5DDC-4043-86D6-2F5D6C286B02.html – we need to enable JMX on the appnode to use JVisualVM to monitor appnode.

Below are the properties that need to be added BW appnode.tra(%TIBCO_HOME%\bw\6.3\domains\%domain%\appnodes\%AppSpace%\%AppNode%\bin\ bwappnode-%AppNode%.tra) to enable JMX.

#Enabling JMX on AppNode

Jmx.Enabled=true

java.property.com.sun.management.jmxremote=true

java.property.com.sun.management.jmxremote.port=8999

java.property.com.sun.management.jmxremote.authenticate=false

java.property.com.sun.management.jmxremote.ssl=false

Below is the screenshot of appnode.tra

Restart the appnode after adding above properties.

Now we can use JVisualVM to monitor appnode as described in Monitoring Threads and Taking Thread Dump Using JVisualVM(https://docs.tibco.com/pub/activematrix_businessworks/6.3.4/doc/html/GUID-BAC813F8-5DDC-4043-86D6-2F5D6C286B02.html)

Thank you!

Registering BW AppNode as Windows NT Service

  1. Navigate to appnode bin directory e.g. D:\tibco\bw\6.3\domains\ERP\appnodes\ERPAppSpace\ERPAppNode\bin
  2. Edit the appnode TRA file e.g. bwappnode-ERPAppNode.tra & add the following lines

                       +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

ntservice.name=ERP_AppNode_SVESBD20

ntservice.binary.path.absolute=D:/tibco/bw/6.3/domains/ERP/appnodes/ERPAppSpace/ERPAppNode/bin/bwappnode-ERPAppNode.exe

application.args=-config D:/tibco/bw/6.3/domains/ERP/appnodes/ERPAppSpace/ERPAppNode/config.ini start

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

3. Open a command prompt , navigate to D:\tibco\bw\6.3\domains\ERP\appnodes\ERPAppSpace\ERPAppNode\bin & execute the following command

bwappnode-ERPAppNode.exe –install

4. The appnode will be registered as a Windows service under”ERP_AppNode_SVESBD20″ name. Modify the service property to log on as the desired user having access to SQLserver DB/File System(in this case)

5. Start the service; confirm that the appnode has started in TEA.

Importing HTTPS-WSDL to Service Descriptors in BW6 application

Process is explained using https://%server%/XRMServices/2011/Organization.svc?singleWsdl

  1. Get the certificates form URL – follow the steps below.

  1. Import the certificates to ‘cacerts’ under %tibco_home%\tibcojre64\1.8.0\lib\security by executing keytool –importcert from %tibco_home%\tibcojre64\1.8.0\bin

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

keytool -importcert -alias CRMDynamics -file %location of certificates% -keystore c:\tibco_bw6\tibcojre64\1.8.0\lib\security\cacerts

keystore password: changeit

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

  1. In TIBCO Business Studio

  1. The WSDL will be added to Service Descriptors folder

IBM DB2 JDBC Connection Resource Configuration

Below is the procedure to connect DB2 version – DB2 for i V7R2 TR4 using drivers – db2jcc4.jar, db2jcc_license_cisuz.jar.

We had following exception when we click on ‘Test Connection’ after configuring JDBC Connection resource as below.

The above exception would be solved by adding db2jcc4.jar, db2jcc_license_cisuz.jar at %BW_HOME%\6.3\config\design\thirdparty\

When we try to run/debug the application. We will be faced with following exception

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

The above exception could be solved making the driver available for run time.

%BW_HOME%\6.3\config\drivers\shells\jdbc.db2.runtime\runtime\plugins\com.tibco.bw.jdbc.datasourcefactory.db2\lib

c:\tibco_bw633_new\bw\6.3\bin\bwinstall.exe db2-driver

Restart the Business Studio, our application should be able communicate with DB2.

Installing Maven and Maven Plug-in for TIBCO BW

  1. Download apache-maven-3.3.9-bin.zip from https://maven.apache.org/download.cgi
  2. Extract apache-maven-3.3.9-bin.zip and copy it to your installation directory(eg C:\ as shown below), this all that has to be done from installation of Maven.

  3. Add a new system ‘M2_HOME’ = C:\apache-maven-3.3.9

  4. Add C:\apache-maven-3.3.9\bin to path system variable.

    Above are the prerequisites for installing BW6 Maven plugin.

  5. Verify Maven installation as shown below from command prompt.

  6. Unzip TIB_BW_Maven_Plugin_1.1.0.zip from ….\bw6-plugin-maven-master\Installer
  7. Run C:\Users\cch\Downloads\bw6-plugin-maven-master\Installer\TIB_BW_Maven_Plugin_1.1.0\install.bat from command line, provide tibco BW6 home where you would like to install the plugin(eg: c:\tibco_bw6)

    After ‘BUILD SUCCESSFUL’ message at the end, maven plugin would have been installed successfully in provided tibco home.

  8. Verify that maven plugin has been installed successfully by opening ‘studio for designers’ and right click on any application. You should see ‘Generate POM for Application’

  9. Type the goal as “package” to create an EAR file.
  10. Type the goal as “install” to create an EAR file
