Top 17 Oracle Bam Interview Questions You Must Prepare 20.Apr.2024

BAM adapter is used when we want to do monitoring at composite level or when we need to monitor full message.

Below are the features of BAM:

• With BAM, end users, operational managers and to some extend analysts get a real-time overview of the state of ongoing affairs.
• It is required to improve decision-making processes.
• It is also used to understand Key Performance Indicators (KPI) affecting processes.

There are two types of sensor actions.

• Sensor action
• BAM sensor action

Sensor action is linked to sensor. In sensor action we define what action we need to perform on sensor data.

Business Activity Monitoring has alert feature which we can use when we want to perform some action based on some data insertion or data change.

BAM has 4 components:

1. Active Viewer
2. Active Studio
3. Architect
4. Administrator

Enterprise Message Sources (EMS) is used by applications to provide direct Java Message Service (JMS) connectivity to the Oracle BAM Server. Each EMS connects to a specific JMS topic or queue, and the information is delivered into a data object in the Oracle BAM Active Data Cache.

We used this sensor when we need to directly send the sensor data to BAM data object.

We can use below options available to monitor SOA service.

• BAM Adapter
• Sensors

Data objects are tables that store raw data in the database. Each data object has a specific layout which can be a combination of data fields, lookup fields, and calculated fields.

Sensors are used when we want to do variable and activity level monitoring.

By using sensor action we can publish the sensor data to Database, JMS Queue/topic, Custom Java and JMS adapter.

By using EMS (Enterprise Message Source).

Yes, we can use BAM alerts to invoke external web service.

Active Viewer:

• Oracle BAM Active Viewer is the thin user interface for the business user.
• When new, information is available; the user receives an instant message that contains a link to the information.
• The user opens Active Viewer through this link and a report is displayed.
• Report formats include charts, columns, cross tab, spread sheets, KPIs, lists and more.
• These different formats can be combined in one report or viewed in separate reports.

Active Studio:

• Oracle BAM Active Studio is the thin user interface for the power user.
• Through Active Studio, the power user can create and edit reports.
• Report creation includes field selection, formatting, filtering, calculated fields, and summaries.
• Reports may be published and rules can be created for determining the scheduling and delivery of the reports.
• View types include: charts, columnar, cross tab, spread sheets, KPIs, lists and more.

Architect:

• Oracle BAM Architect is the thin user interface for the data designer focused on creating data objects in the Oracle BAM Active Data Cache so that power users can create reports.
• Through Oracle BAM Architect, the data designer creates data objects, creates and schedules data flow pl, imports and creates metadata, and maintains the data objects and rules.
• Oracle BAM Architect is seamlessly integrated with Oracle BAM Active Studio.

Administrator:

• Oracle BAM Administrator is the thin user interface for the system administrator who is responsible for user management and overall server management.
• Through Oracle BAM Administrator, the system administrator can add or delete users, define security levels for users and objects, manage the Oracle BAM Active Data Cache, and maintain and configure Oracle BAM services.

BAM stands for Business Activity Monitoring.  This monitors various types of business activities, reports on them and sends out alerts when thresholds are reached or surpassed.

Yes, we can have user based access in BAM.
