Study guide for Data Systems Administration WGU D330📝
The comprehensive study guide we present to you involves going through many different resources to give you the best study path through the course content of this module. The only advice you should know before starting is to take your time to go through every one of the steps we have laid down for you. Everyone has a different learning pace, so do not worry about the timeline. Take all the time you need to grasp the course content to achieve your best in the Objective Assessment of D330.
Step 1
The first course of action in our study guide is to go through the course content to get a grasp of the theory that we need to cover in this module. To accomplish this step we will use the below listed resources to assist us.
- Oracle – 12c Database Administration LinkedIn course by David Yahalom
- Oracle Database 12c Backup and Recovery LinkedIn course by David Yahalom
Note that you are only required to go through the theory parts of these courses, the hands-on materials in these courses are additional and they are not part of our study guide.
While you are going through these courses, it is important to take short notes on each topic to help you memorize the core concepts. These short notes will also help you revise the course content later when you are ready to attempt the OA of this module.
Step 2
As the second step of our study guide, we recommend you read the EtextBook provided by WGU for the module. It is important to read through this resource because the OA questions are only based on this book. Reading through the book will assure you that you will have the knowledge to answer each and every question that you will get in the OA.
If you do not have enough time to read through the entire book, worry not. We have identified the specific chapters of this book that carry the most weight in the OA. So Make sure you at least go through the below chapters in the book and make sure that you take short notes on these chapters as same as you have done in the previous step. You should also pay close attention to the acronyms in these chapters and also the sections that are in bold or italics.
- Chapter 8 – Introducing Oracle Database 12c Components and Architecture
- Chapter 9 – Creating and Operating Oracle Database 12c
- Chapter 10 – Understanding Storage and Space Management
- Chapter 12 – Understanding Oracle Network Architecture
- Chapter 13 – Implementing Security and Auditing
- Chapter 14 – Maintaining the Database and Managing Performance
- Chapter 15 – Using Backup and Recovery
- Chapter 17 – Upgrading to Oracle Database 12c
Step 3
At this point in your journey, you should have a strong grasp of the course content as you have gone through them twice in both step 1 and step 2. The rest of our journey will compromise on retaining that knowledge to ace your OA of D330.
In this step, we will go through the webinar conducted by Dr. William Swell. Click on this link to access the video. This webinar will be a major assistance in helping you revise the key concepts and help you memorize them before sitting for the assessments.
Step 4
Now it is the time to test your knowledge. Let us put the effort and time you spent on studying the course material and test how far you have come. Log into your student’s account on the WGU website and navigate to the module Data Systems Administration WGU D330. There you can find the Pre-Assessment of the module. Make sure that you are confident in your knowledge before starting the Pre-A because you should treat this assessment as the real OA to test your knowledge and verify that you are ready for the final challenge. Find a calm and quiet environment, get comfortable and start the Pre-A. Read each and every question clearly before answering the questions and take your time to do so. If you try to skim through all the questions, you will be only doing a disservice to yourself.
Once you have completed the Pre-A, a coaching report will be automatically generated on the same webpage where you found the Pre-A. This report contains your score on the Pre-A and it clearly describes your skills in each topic of the module. This is a great tool to find your weaknesses and where you need to work in your knowledge. Use this report and go through the topics where you scored the lowest once again to revise your memory. Once you have done so, move to the next step.
Step 5
Another widely popular technique to memorize the key points in the course content is to take quizzlets built on the subject matter. These quizzlets are a very convenient method of studying as you can go through them easily, even when you are busy with your chores at home or taking public transport. Use your smartphone to access the below links and go through these quizzlets as much as you would like. The first 70 questions in quizzlet#1 are the same as the pre-assessment that you faced in the earlier step. So make sure to attempt these questions once again.
Quizzlet #1 (Contains questions from the pre-assessment and the questions from the end of each key chapter)
Quizzlet #2 (Skip to the first 70 questions and start from question #71)
If you are able to go through these quizzlets with ease, you are ready to tackle the final assessment of D330.
Step 6
Now that you are ready to attempt the OA of the module, you should be confident in your knowledge of all the key topics we have mentioned earlier. You can also use the “d330 test help.docx” document in the course chatter of the module to act as a reference guide. This document will give you an overview of the knowledge that will be tested in the OA. To find the document;
Navigate to the Home page of WGU > Go to the Degree Plan tab > Go to the Data Systems Administration – D330 module > Find the course chatter on the right-hand side of the webpage and click on the link
Once you are in the course chatter, you can download the file from the documents listed on the right-hand side of the webpage. (Refer to the below image to guide you)
Now all that is left for you to do is schedule the OA. We recommend that you schedule the OA as soon as possible to give you the best chance of acing it. This will help you go to the OA directly with the knowledge that you have retained before you start to forget it. Make sure that you use the same strategies that you used for the Pre-A. First, read through the guidelines and rules carefully and make sure there is no issue in your study environment with the proctor. Once you start the assessment, carefully read through every question and understand the ask of the question before choosing the answer. If you do not remember the answer, use the elimination method to narrow down the choices. If you have any doubts in a question, make sure to bookmark them, so you can revisit them at the end of the assessment. Most of all be calm and confident and believe in yourself. Good luck!!
Key Topics in D330🔑
In this section of the article, we are going to discuss some of the key concepts and terms of the module Data Systems Administration WGU D330. When you are studying through the course material, focus on these topics to have a better advantage in the final assessment.
Pfile vs Spfile
Both pfile and spfile serve as configuration files for Oracle databases, the spfile offers advantages in terms of security and manageability. Understanding how to work with both types of files is essential for effective Oracle 12c database administration.
1. Parameter File (pfile):
- The pfile, short for “parameter file,” is a static, text-based configuration file used by Oracle databases.
- It contains initialization parameters that control the behavior and settings of the Oracle instance.
- These parameters are written in a human-readable format and can be edited directly using a text editor.
- The pfile is typically named “init.ora” and is located in the Oracle database’s “dbs” directory.
- Changes made to the pfile require a database restart to take effect.
2. Server Parameter File (spfile):
- The spfile, or “server parameter file,” is a binary file that serves the same purpose as a pfile but with some key differences.
- Unlike a pfile, the spfile is stored in a binary format within the Oracle database itself.
- This makes the spfile more secure and less susceptible to human error, as it cannot be directly edited with a text editor.
- Changes to parameters in the spfile can be made using SQL commands, such as ALTER SYSTEM SET.
- The spfile is typically named “spfile.ora” and is located in the Oracle database’s “dbs” directory.
Block Change Tracking
Block change tracking is a feature designed to enhance the performance of incremental backups. Here’s how it works:
Tracking Block Changes: Block change tracking keeps track of the modified data blocks in the database since the last backup. It maintains a record of which blocks have been changed, allowing for more efficient identification of data that needs to be backed up during incremental backups.
Improving Backup Performance: By knowing which blocks have been changed, block change tracking significantly reduces the amount of data that needs to be backed up during incremental backups. This optimization minimizes the time and resources required for backups, as only the changed blocks are copied, rather than the entire database.
Reducing Backup Window: With block change tracking enabled, the backup window – the duration required to perform backups – is typically reduced. This means that backups can be completed more quickly, minimizing the impact on system performance and downtime.
Enabling Faster Recovery: In addition to improving backup performance, block change tracking can also facilitate faster recovery in the event of data loss or system failure. By tracking block changes, the database can quickly identify the changed blocks needed to restore the database to a specific point in time.
Oracle Startup Process
The startup process involves several levels, each serving a specific purpose in initializing the database. Let’s explore what happens at each level:
Nomount Stage:
- During the nomount stage, the instance is started, but the database is not mounted.
- At this stage, Oracle reads the initialization parameter file (pfile or spfile) to determine the configuration settings for the instance.
- The database control files are not accessed or opened during this stage.
- This stage is typically used when creating or altering the database’s structure, such as creating or modifying tablespaces or data files.
Mount Stage:
- In the mount stage, the instance is started, and the database is mounted but not opened.
- Oracle reads the control file(s) to locate the data files and redo log files associated with the database.
- The control file(s) are opened and accessed during this stage to determine the database’s physical structure.
- This stage is used when performing tasks that require access to the control files, such as restoring backups or performing certain administrative operations.
Open Stage:
- In the open stage, the instance is fully started, and the database is opened for user access.
- Oracle reads additional files, such as the data files and redo log files, to complete the database’s initialization.
- User sessions can connect to the database, and SQL statements can be executed against it.
- This is the normal operating mode of the database, where it is available for regular use.
Each level of startup in Oracle 12c database administration serves a specific purpose in the process of initializing the database, allowing for different actions and operations to be performed at each stage.
