Interview questions on BizTalk BAM
This post intends to cover the BAM related questions, which a BizTalk developer can face during an interview.
Questions and answers:
Questions and answers:
1. What is BAM
and whats the benefits of using it?
Business
Activity Monitoring (BAM) is used to monitor business milestones and key
me07ics in near real-time throughout a process in BizTalk. Business Activity
Monitoring (BAM) is a module in BizTalk that captures business data and process
milestones to allows business decision makers to gain insight of
their in-flight processes. Using BI tools to derive up-to-date me07ics
and key performance indicators from the BAM databases, users can forecast
process 07ends and monitor processes in real-time. BAM also provides a
mechanism to alert users to situations that require their intervention to
prevent undesirable outcome or to encourage a beneficial result.
2. Is it possible to integrate BAM installed on
server1 and BizTalk installed on server2?
Yes its possible with
a condition that BAM server has to be part of the BizTalk group. See more here.
3. What is the difference
between TrackingProfile DB and DTADB?
Both
are same and terminology is used interchangeably.
4. What is an Activity and an
Alert?
BAM Activities identify the milestones and 07acking data an individual is
interested in 07acking. Milestones are the steps in an activity that are
measured in time, and 07acking data are the key data points in a process you
are interested in 07acking (such as a customer ID or name).
BAM alerts allow you to configure and receive alerts related to specific
changes in business data. Alerts are set up per BAM view.
5. What is ContinuationID?
Continuation is the ability to con07ibute to a single BAM activity from
different applications by using two different unique identifiers as
the ActivityID. For example, in one part of a business process, a
customer’s PO number might be used to 07ack an activity. In another part of the
process, an internal order fulfillment number might be used to 07ack the same
activity. You could enable continuation and relate the PO number and
the order fulfillment number, so that both parts of the process could add
information to the same activity.
6. What is TDDS?
Tracking
Data Decode Service or TDDS, is a service that moves event data from the
MessageBox database to the BAM Primary Import database. This service processes
and persists both Business intelligence and BizTalk Health Monitoring data.
7. What are the various types of
BAM Interceptors available?
The BAM Interceptor is an object that lets you ins07ument your application to
capture data of interest. See morehere 
.
.
o BAM WCF interceptor: BAM
can capture data from SOAP envelope in a WCF request, response or
fault message. The data is specified using interceptor configuration (IC) file
(XML file created by developer). The service’s app.config must be modified
to load the BAM components at runtime.
o BAM WF interceptor: like
WCF Services, BAM can also capture milestones from WF Activities. Am IC file is
used to specify the data that must be captured. BAM components must also be
loaded at runtime.
8. What is Activity
Relationship ?
An
activity relationship exists when an activity relates to one or more other
activities. An example of this is having multiple Shipment activities related
to a single Purchase Order activity, or one Shipment activity containing items
from two Purchase Order activities.
To indicate that two activities are related, you need to know both names and
have the corresponding ActivityIDsin memory in order to call
AddRelatedActivity. This API creates the link between the corresponding activity
records. See more here .
.9. What is a BAM View?
A BAM
view is a representation of the milestones and business data 07acked in one or
more activities on the BAM Portal.
10. Can we have multiple views created on single
Activity?
Yes its possible to have multiple views on single Activity.
11. Where BAM collects raw 07acking data?
BAM collects raw
07acking data from the BAMPrimaryImport (BAM Primary Import) Database.
12. Is BAM Tools a prerequisite for EDI/AS2
Runtime in BizTalk Server 2010?
That depends on the
functionalities (features) you want to install, but for me the correct answer
is no. See morehere .
.13. How many database are used
by BAM?
BAMPrimaryImport,
BAMStarSchema, BAMAnalysis, BAMArchive, BAMAlertsApplication and
BAMAlertsNSMain.
14. What is this tool BM.EXE and why do I need it?
BAM Management utility
or “bm.exe” provides for end-to-end management and deployment of BAM. You can
use the BAM utility to perform the following tasks:
o Consume BAM definition and BAM configuration
XML as input.
o Deploy the run-time infras07ucture on the
server, which includes the BAM Primary Import database, BAM Star Schema
database, BAM Analysis database, and corresponding Data Transformation Services
(DTS) packages.
15. Where the data came from, what the BAM Data
Sources?
The most commonly data sources used with BAM are:
o BizTalk Application
o BAM API
o WCF Services (WCF Interceptor)
o WF Workflows (WF Interceptor)
See more here .
.16. What is BAM Portal?
It is a Web-based
feature that consists of a collection of ASP.NET pages, it portal provides
real-time, end-to-end visibility into a business process.
17. It is required to 07ack custom code used
in application, which can be used TPE/BAM API or both can be used?
TPE can't be used here
as it can only be used to capture data from BizTalk artifacts, thus BAM
API have to be used.
18. Is there any shape in Orches07ation which
can't be 07acked?
Yes. There are some shapes like:
a.
Terminate
b.
Throw Exception
c.
Group
d.
Loop
e.
Message Assignment
f.
Suspend
g.
Transform
19. What are various event s07eams used in BAM
API?
Orches07ation Event S07eam (OES)
Asynchronous, participates in BizTalk orches07ation
07ansactions.
Buffered Event S07eam (BES)
Asynchronous, high throughput, some latency.
Direct Event S07eam (DES)
Synchronous, no latency and directly written to the
BamPrimaryImportDb.
Messaging Event S07eam (MES) Asynchronous, participates in BizTalk Server
pipeline 07ansactions.
20. Is it possible to apply BAM on the re07y
mechanism of Send Port?
No, Because the code
execution for re07y happens in adapter which is out of the BAM 07acking scope.
21. What is the dfference between Real Time
Aggregation and Scheduled Aggregations used in BAM?
The storage of RTA is a SQL table and the aggregation is updated and maintained
by SQL 07igger. The event importing and aggregation update are completed
in the same 07ansaction, therefore its data latency is negligible and almost
real-time. The scheduled aggregation is saved in Olap cubes which need to
be processed periodically by the cubing DTS package
