Webservice Description Language (WSDL)
Webservice Description Language (WSDL)
Webservice is a software system designed to support interoperable machine to machine interaction over a network. In otherwords, it is a Client-Server model based application. WSDL is Webservice Description Language which is an XML based language that provides a model for describing webservices. The main advantage of the webservice is that we can pass values at run time. WSDL uses a certain standard format called SOAP which is Simple Object Access Protocol. The structure of SOAP has a Header, Body and Attachment.
WSDL has Abstract wsdl on the server side and Concrete wsdl on the client side to perform machine readable description of the operations offered by the service.
Abstract wsdl is the core of the web service. All services are defined in the abstract wsdl. It is a Server Side WSDL. Abstract wsdl contains only messages and operations. Abstract wsdl is used by SOAP Server. Request and reply operations are created with a port type.
Concrete wsdl is the WSDL that allows a client to connect (and work with request/response) to a Web Server.It contains the metadata for sending a correct request and receiving correct response. Concrete wsdl contains messages, operations and transport specific information (JMS or Http). This is used by SOAP client.

Out of Memory Error in BW Application
Out of Memory Error in BW Application
In some running applications, suddenly you started hitting out of memory errors. To drill down more, Check the max heap size you configured while deploying time.
If the running application thrown out of memory error, you can simple go ahead and test from designer with the same amount of input, some where the funny coding is taking all your memory.
If it is new application, set the heap suggested is multiples of (64MB), and keep increase, if it is keep throwing just open the code check with the same load and see which activity is taking all the memory and take corrective steps.
For ex:
If you are not properly using parse data activity in your code, this will end up eating more than 2 GIG for 20 MB file.
Solution :
Heap settings will be done at Admin level, to do that login to TIBCO administrator, and navigiate process specific server settings, and change the heap values.

Custom Database Driver in JDBC Connection in Tibco
Custom Database Driver in JDBC Connection in Tibco
The following drivers are included in the TIBCO BusinessWorks installation:
oracle.JDBC.driver.OracleDriver (oci)
The following drivers are JDBC 2.0-compliant and should work correctly, but they are not officially supported with BusinessWorks. You must obtain, install, and configure the driver from the appropriate vendor:
sun.jdbc.odbc.JdbcOdbcDriver
You can download, install, and use other JDBC drivers, but TIBCO does not guarantee the drivers will function properly with TIBCO BusinessWorks. To use an unsupported driver, perform the following:
Download the JDBC driver and copy the required JAR files to a location in the classpath of the TIBCO BusinessWorks Engine. For example, you can copy the files to the following location: TIBCO_HOME/tpcl//jdbc.
The following drivers are included in the TIBCO BusinessWorks installation:
- tibcosoftwareinc.jdbc.oracle.OracleDriver
- tibcosoftwareinc.jdbc.sqlserver.SQLServerDriver
- tibcosoftwareinc.jdbc.sybase.SybaseDriver
- tibcosoftwareinc.jdbc.db2.DB2Driver
oracle.JDBC.driver.OracleDriver (thin)
com.sybase.jdbc2.jdbc.SybDriver
com.timesten.jdbc.TimesTenDriver
com.ibm.db2.jcc.DB2Driver
weblogic.jdbc.mssqlserver4.Driver
In the JDBC Connection resource, choose Select Driver from the drop-down list in the JDBC Driver field and type in the name of the driver class in the text box within that field. Then, type in the correct URL in the Database URL field and specify the other fields in the resource.
See TIBCO BusinessWorks Release Notes for more information on the supported and tested versions of databases and database drivers.
