UNIX Commands/ Oracle Performance monitor

Question1
Command System activity report (sar)

The sar command is defined to have the general task of collecting, reporting or rather saving the information resulted from the system activities. The sar command initiates the writing onto the standard data/ information output the selected information regarding a cumulative activity counter performed in the operating system. The command is applicable in the sense of displaying the reports according to the duration that the system takes in writing the information. In the accounting system, the values can be outlined in count and the interval parameters and in this case the system will write the information depending on the intervals in seconds’ time. When the interval parameter is set at zero, then the sar command will only display the average statistics for the duration from the time the system was started. On the other hand the system interval parameter is defined and specified in absence of a count parameter then the sar command will generate reports continuously. Sar command is used for real time monitoring of the linux system performance in statistics (Prasad, 2014. The sar command is also applicable in collecting and storing information upon analysis bottlenecks are easily identified (Nataraj, 2011).

The Unix “Who” command

The who command is very useful for the display and printing of the information that related to the end users of the systems that are currently logged in the system. The who commands is executed for a duration of approximately 5 minutes and in the displays it displays the following information. the list of the users logged in the system, the time of the last boot, a list of dead processes, the list of login processes, counting of the login names and generally displaying the information of the logged on end users. The purpose of the who command is to display the end users logged on the systems. if person bypasses the server you can use the command to determined the persons that logged on your server (Gite, 2014).

Question 2A
Cumulative statistics
The cumulative statistics is described under cumulative probability and the cumulative frequency as well. The cumulative frequency defines the number of observations made that lies either above or below the particular value defined in the data set. And it is achieved or rather calculated by the use of the frequency distribution table.teh cumulative frequency is the same as the cumulative percentages though the percentage is advantaged with the power of easily comparing the sets of data. The cumulative probability is described as the probability that describes the value within a random variable will tend to fall within a specified value range.

Database metrics
Database metrics describes the activities undertaken about monitoring the performance of the database. The performance metrics are applied in the assessment of the health of the enterprise database. The metrics can focus on eth business transactions, the query performance, user and query conflicts, the capacity, configuration and the NoSQL databases (Habib, 2015). At times, the metrics are defined as long-term o average and they include the throughput, execution time, the concurrency and utilization.

Question 2B
Automatic workload capture feature
The workloads capture module s quite applicable in the monitoring of the external users activities and related transactions. The feature facilitates monitoring by recording the entire requests made by the database external users to the Oracle database. Once the feature is enabled, all the request done by the external users are redirected and stored in the capture files and this will facilitate the tracking of the transaction done by the external users. The capture files stores the information of SQL text, the bind values and the transaction information (Oracle, n.d).

Automatic performance diagnostic feature
The feature is applied when a problem is felt to have occurred within the database and thus the necessity of performing accurate and timely diagnosis of the developed problem before any measure of making changes.Teh automatic database diagnostic monitor undertakes an analysis of a top down series with the prior identification of the symptoms and then refining the symptoms until the cause of the performance problem is determined.

Post-Graduation Self-Promotion Plan

Post-graduation self-promotion plan is a systematic process and activities that portray a graduate as an expert in their field, attract the ideal and potential employer and reveals how the graduate can help the business. A graduate should understand (Nelson, 2015):

The target audience to whom you will direct the promotion
Why you are going to promote yourself to the identified audience
What you are going to say about yourself during promotion
The plan has goals that it should meet to help the job candidate succeed in the process of job hunting. Some of the goals are (Georgiou et al., 2012):

To help provide direction thereby eliminating trial and error that would lead to saving time and money
To help and network with the main industries that fit the candidate career
To help the job candidate identify the skills that can be transferred
Determine various industries where the transferable skills fit
Resolve any challenges that hurt the candidates career and prevent the candidate from being invited for interviews
Candidate’s mission statement should appear in their plan. The mission state should, however, say what is important to the job candidate. The mission statement helps the candidate get his job hunting on track while also connecting with organizations with similar values and beliefs (Nasser & Abouchedid, 2012).

Key Self Promotion Tools
Market research: The tool involves the job candidate understanding trends in their field. They should also consult various resources such as the United States Department of Labor’s Occupational Outlook Handbook while also interviewing the professionals in the industry. They should also study the company they would like to work for and then use the information to write a cover letter and the resume (Tziner, Vered, & Ophir, 2004).
Marketing mix: The candidate should be familiar with the 4 Ps of marketing otherwise known as marketing mix that are a product, promotion, place, and price. The job candidate should then translate them regarding themselves and their career for success in job seeking (Tziner, Vered, & Ophir, 2004).
Product: The job candidate is a unique product with unique features and skills. The candidate should expose the features in the resume. They should let the employers know about the relevant job and leadership experience, membership to professional bodies, relevant skills, training, and education. On the same note, the job candidate should ensure their online promotion tools such as Facebook are clean and ready for the employer (Tziner, Vered, & Ophir, 2004).
Marketing: The tool addresses the cover letter, resume, phone calls, and interviewing. Marketing includes various things the candidate can use to get invited for an interview and eventually a job offer (Tziner, Vered, & Ophir, 2004).
Place: The tool includes various places the employer can access the job candidate. The candidate should ask themselves how they are reaching potential employers or people who can connect them to employers. It includes Internet job searching, cold calling, and networking among others (Tziner, Vered, & Ophir, 2004).

Transcribe an Audio

Riboswitches are regulatory elements transcribed RNA model. They respond to changes in PH, and temperature. A riboswitch consists of an element such as physical ligands which are bound together forming riboswitch binding site. ON the point binding to the ligand there is a confirmation switch connected to the riboswitch. The binding of a ligand to the riboswitch affects the expression of the gene directly connected to the riboswitch. And the gene product is responsible, for allowing the bacteria to respond to the ligand bound to the riboswitch. For example, if you have a ligand bound to a riboswitch and binding integration causes transformation changes in gene expression it will impact the expression of the linked chain which it gene products affects that ligand.

There are different regulatory outcomes and models that result when ligands bounds and dissociate from ribosomes. The first example shows the ribosome binding site located down. When the ligand binds, it causes transformation changes and ends up forming several structures, and in references to genetics, the structures formed will copy transformations, and termination gene products fall prematurely. If there is an operating frame the gene located in the DNA, it cannot transcribe that gene in the DNA model. In other words, the gene products won’t be synthesized because there are transcriptions formed on the DNA model. In the second example the ligand is not bound, so transcriptions are formed without the ligand. The riboswitches will affect the transcription of down changes. They affect translation. The ribosome binding site is facing different site thus it is not exposed for ligand binding. Hence there are no binding and ribosomes cannot translate. The functions of the ligand are therefore prevented. The ligand facilitates opening of the region allowing ribosomes to bind and translate. Riboswitches affect transcription in presence and absence of ligands.

There are millions of transcriptions and translation on a linked chain. The regulatory elements that only affects expansionary gene directly connected to the same riboswitch or DNA molecule are called cease regulatory elements. For example, in case there are two DNA molecules the expression of the gene is usually affected by the presence of regulator and promoter. The promoter is a cease regulatory element which only affects the gene linked to same DNA molecule. Riboswitches are found in a various number of packages such as Flavin mononucleotide (FMN) has similar functions to a co-factor. A cofactor is an organic or inorganic ion, or molecules required an active reaction. A riboswitch is responsive to the presence of FMN, in the absence of FMN, there is a determinator that forms between riboswitch and operating frame so that there can be continuous transcription and translation. In the presence of FMN, it binds to riboswitch, there is transformation changes and produces transcription terminators that prevent the transcription of genes to RNA model. The riboswitch simulates pathogens which are a form of infection pulses which causes mysterious infection. Riboflavin is an analog form of FMN which means that they are similar to each other Riboflavin has similar effects as FMN.

Transcriptional interference occurs when transcription from one stride prevent another transcription from happening the condition happens in the absence of enough methyl. In the presence of methyl, the riboswitch forms a transcription terminator, and there is no obstruction of production of genes sequences. There is a complete synthesis in the presence of methyl. The cells can sense the amount of substrate. Gene rearrangements are not similar to mutations. Gene rearrangement is a reversible process which is applied to bacteria during its development process.
