Oracle BPM Interview Questions

1) How to initiate process in OBPM 11g / How to initiate OBPM process in 11G?

Ans:

Four ways:

1. Human Activity (Initiator).

2. Message wait.

3. Timer.

4. Signal.

2). How can I achieve presentation in OBPM 11g?

Ans:

In OBPM 10g presentation available , but In OBPM 11g Oracle came up with ADF ( Application Development Framework ) so we can create rich application ( In simple term View MVC pattern ). know more at Oracle bpm online training

3) How can I see my BPM application in workspace ? any global activity present to Initiate process ?

Ans:

After you deployed OBPM Application in web-logic domain, you can able to see only your BPM project name in workspace, as per my knowledge no global creation present in OBPM 11g .

• Definition: Business Process Managemet
• Description:

It is a methodology that provides the management team and the organization as whole with a clear perspective on how the work is actually performed. Most management teams believe that their organizations are process oriented, and they understand how their products or services are delivered to their customers. The reality is that they don’t really understand how the work is actually performed

4) What Does BPM Provide?

Ans:

BPM provides a shared understanding of the key business processes, their linkages, and their dependencies. It enables management to understand how work is performed across the organization to deliver value to customers and determine the correct skill sets required for employees, the appropriate technology tools to implement, and the appropriate business rules required for repeatable process execution.

5) What is Level 0, Level 1 backup?

Ans:

• A level 0 incremental backup, which is the base for subsequent incremental backups, copies all blocks containing data, backing the datafile up into a backup set just as a full backup would. A level 1 incremental backup can be either of the following types:
• A differential backup, which backs up all blocks changed after the most recent incremental backup at level 1 or 0
• A cumulative backup, which backs up all blocks changed after the most recent incremental backup at level 0

6) How do you setup the RMAN tape backups?

Ans:

Configure channel as SBT_TAPE and use “ENV” parameter to set the tape configurations.

7)What is the init parameter specify the minimum number of days that Oracle keeps backup information in the control file

• You can use the CONTROL_FILE_RECORD_KEEP_TIME parameter to specify the minimum number of days that Oracle keeps this information in the control file. know more at Oracle bpm training

8)What is the difference between validate and crosscheck.

Ans:

The restore … validate and validate backupset commands test whether you can restore backups or copies. You should use:

• – restore … validate when you want RMAN to choose which backups or copies should be tested.
• – validate backupset when you want to specify which backup sets should be tested.

9) What is backup set?

Ans:

RMAN can store backup data in a logical structure called a backup set, which is the smallest unit of an RMAN backup. A backup set contains the data from one or more datafiles, archived redo logs, or control files or server parameter file.

10)What is Channel? How do you enable the parallel backups with RMAN?

Ans:

Use the ALLOCATE CHANNEL command to manually allocate a channel, which is a connection between RMAN and a database instance. To enable the parallel backups, allocate multiple manual channels in the run block or configure parallelism

11) Outline the steps involved in CANCEL based recovery from the full database from hot backup?

Ans:

RMAN doesn’t support cancel-based recovery like SQL*plus does.

12) What is the difference between validate and crosscheck ?

Ans:

The restore … validate and validate backupset commands test whether you can restore backups or copies. You should use:

• – restore : validate when you want RMAN to choose which backups or copies should be tested.
• – validate backupset when you want to specify which backup sets should be tested.

13) What is Web service?

Ans:

Ans :Web services are application components, which are self-contained and self-describing and provide services based on the open protocol communication (i.e SOAP UI, HTTP over the net).

14) What is SCA?

Ans:

Service Component Architecture (SCA) provides a programming model for building applications and systems based on a Service Oriented Architecture. SCA is a model that aims to encompass a wide range of technologies for service components and for the access methods which are used to connect them. know more at Oracle bpm online course

15) What is SOA?

Ans:

Service Oriented Architecture (SOA) is used to develop Enterprise applications by using a collection of services which communicates each other. Service-Oriented Architecture (SOA) is a set of principles and methodologies for designing and developing software in the form of interoperable services.

16) How do I go about backing up my online redo logs?

Ans:

Online redo logs should never, ever be included in a backup, regardless of whether that backup is performed hot or cold. The reasons for this are two-fold. First, you physically cannot backup a hot online redo log, and second there is precisely zero need to do so in the first place because an archive redo log is, by definition, a backup copy of a formerly on-line log. There is, however, a more practical reason: backing up the online logs yourself increases the risk that you will lose

17) What are the main benefits of SOA ?

Ans:

• SOA helps create greater alignment between IT and line of business while generating more flexibility — IT flexibility to support greater business flexibility. Your business processes are changing faster and faster and global competition requires the flexibility that SOA can provide.
• SOA can help you get better reuse out of your existing IT investments as well as the new services you’re developing today. SOA makes integration of your IT investments easier by making use of well-defined interfaces between services. SOA also provides an architectural model for integrating business partners’, customers’ and suppliers’ services into an enterprise’s business processes. This reduces cost and improves customer satisfaction

18) What is SOA and explain its architectural benefits?

Ans:

SOA is the acronym for Service Oriented Architecture and is useful in developing the integration plugins or services for the integration of different cross technological or cross-platform applications. SOA architecture has several benefits such as the development of loosely coupled components, easy reconfiguration of the existing services, reusing the existing SOA services without affecting the business functionalities, Ensures Data Confidentiality and Security, Better Maintenance and Flexibility of maintaining the services.

19) What are the different components involved in the SOA Architecture?

Ans:

The different components present in the SOA Suite are as below–

1. Services
2. Process Layer or Orchestration layer
3. Access Framework
4. Business Activities Monitoring
5. Operational Data Stores
6. Security
7. Management
8. Partners, Suppliers, and Customers

20) What are the different types of Services available in SOA?

Ans:

• The different types of Services available in SOA Service-oriented Architecture are SOAP and REST-based which ar
