What
is the difference between Concrete WSDL and Abstract WSDL?
The Abstract WSDL describes the
interface of the web service which includes the format of request and response
messages of each operation.
The Concrete WSDL describes the
abstract WSDL plus transport information. Concrete WSDL contains messages,
operations and transport specific information (JMS or Http), which is used by
SOAP client.
What
is the Difference between EMS and RV?
EMS
EMS
·
A
producer sends a message to the central server. The server stores the message
until it has delivered it to each consumer
·
Producer
to server; server to consumers.
·
Store
and forward queue protocol.
·
The
central server stores all messages and delivery state for all its clients; it
requires disk resources in proportion to total throughput volume.
·
Disk
failure on a server host computer can be catastrophic, affecting all messages
from every client. Many installations protect against disk failure using
safeguards such as disk mirroring.
·
The
central server is the master of overall delivery state.
RV
·
A
producer sends a message to consumers. The producer stores the message until
each consumer has acknowledged receipt
·
Peer-to-peer.
·
Stream-oriented
protocol.
·
Each
producer stores its outbound messages and some delivery state; it requires disk
resources in proportion to its outbound volume.
·
Disk
failure on a peer host computer affects only the messages that its programs
produce or consume. However, disk mirroring for each individual peer is often
impractical.

What
is difference between AliasLibrary and LibraryBuilder?

An
Alias Library is used to access some java classes which are part of a jar file.
What
is BW memory management?
Memory saving mode can reduce the memory used by actively running process instances as well as potentially improve the performance of checkpoints. By default, memory saving mode is disabled, but you can enable garbage collection on specific process instances by setting the EnableMemorySavingMode. property to true. You can enable memory saving mode for all process instances by setting the EnableMemorySavingMode property to trueEnableMemorySavingMode. = true

Try
this property adding your Deployment Tra file or BW Engine.Tra file and
Redeploy it. But memory saving is very limited though, make sure if your
process is claiming more heap and/or reaching to out of memory exception, there
is something wrong with process design, verify each actitivity and cleanup all
unused content.

Do
we have to redesign the project if we make some changes in XSD's like
Enumeration changes or just update them?
If you modified any property (Enumeration..etc) for any field in in Schema, you need not re-design your project. It's just property, it automatically imported where ever you’re using (diff process) this schema.

What
is difference between Soap Event Source and Service activity?
Soap Event Source supports only one operation to be implemented, if you have a need to have multiple operations in one place, you can use services as it supports multiple operations in one place.

What
is Check point? What is the use of it?
The Checkpoint activity performs a checkpoint in a running process instance. A checkpoint saves the current process data and state so that it can be recovered at a later time in the event of a failure. If a process engine fails, all process instances can be recovered and resume execution at the location of their last checkpoint in the process definition. If a process instance fails due to an unhandled exception or manual termination, it can optionally be recovered at a later time, if the process engine is configured to save checkpoint data for failed processes.

How
to Read Excel file in process?
·
You
can save the excel file as .csv file and you can use the same csv format by
giving the column separator and line separator.
·
You
can use JDBC Excel driver, or JDBC-ODBC Bridge and then ODBC Excel driver. Both
methods allow read/write of excel files using SQL
What
is the purpose of Event Candidate Key?
Expression used to evaluate whether the incoming message is appropriate for this process. This expression is specified in XPath, and only data from the incoming event is available for use in this XPath expression.

What
is the use of Event time out?
The amount of time a message will wait (in milliseconds) if it is received before this task is reached in the process. If the event timeout expires, an error is logged and the event is discarded.
The amount of time a message will wait (in milliseconds) if it is received before this task is reached in the process. If the event timeout expires, an error is logged and the event is discarded.
If
no value is specified in this field, the message waits indefinitely. If zero is
specified, the event is discarded immediately, unless this has already been
reached
How
do you achieve to store data from group activities for each iteration?
If you wish to store data from each successive iteration of a loop, you can create a process variable and use the Assign activity in the loop to store or alter data for each iteration. For Iterate and Repeat until True loops, you can optionally accumulate the output of each execution of one activity in the group into a list. This list becomes the group’s output and the list is available to subsequent activities in the process definition

What
is the use of “No action Group”?
You can group a set of related activities, with a common set of transitions into and out of the group. If you do not wish for the activities in the group to repeat, specify the group action to be none. No action groups are primarily useful for specifying a single error transition out of the group so that if an unhandled error occurs in the group, you only need one error transition instead of an error transition for each activity. This behaviour is similar to a try...catch block in Java.

Why
you need “pick First Group”?
Pick first groups allow process execution to wait for one or more events. The first event that completes determines which transition to take to continue processing. For example, as part of an order-entry system, when an order is placed, a check is made to see if the order can be filled from stocked inventory or from returned merchandise. Whichever system returns the information first is used to fill the order. If neither system returns the information about available inventory, the order time out and cancels

What
are the different types of variables are available? And explain them?
·
Global Variables
These
variables allow you to specify constants that can be used throughout the
project. The constants can be specified and changed while designing and testing
your project. You can also specify different values for each deployment of your
project.
·
Process
variables
These
variables allow you to access various data in your project. For example, there
are predefined process variables containing the process ID, project name, and
other information. You can also create user-defined process variables for
containing process-specific data.
·
Shared variables
These
variables allow you to specify data for use across multiple process instances.
Because multiple process instances can access the same variable, you can also
synchronize access across processes when setting or retrieving the shared variable.
Difference
between shared variable and job shared variable?
·
Shared variable
Shared Variable resource allows you to share data
across process instances. All process instances can read and update
the data stored in a shared variable. This type of shared variable is useful if
you wish to pass data across process instances or if you wish to make a common
set of information available to all process instances
·
Job shared
variable
Job Shared Variable resource is similar to a Shared
Variable, but its scope is limited to the current job. A copy of the variable
is created for each new process instance. This type of shared variable is
useful for passing data to and from sub-processes without creating an input or
output schema for the called process.
What is coercion and what is the use of
it?
Coercions allow you to specify a type for Process Data elements that are not a specific datatype. For example, a choice element can be coerced into one of the possible data types for the element, or an element of datatype any can be coerced into a specific data type.
