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.

5 Ways To Write Better Job Descriptions

If you are to get the right candidates in the interview room, you’ll need to appeal to those candidates in the right way. That’s why the writing of the most informative and compelling job descriptions is such a key part of Online Recruitment.

Free Palestine
Here are just some of the techniques you should try to give your own firm’s job descriptions that bit more vital impact and relevance.

1. Come Up With A Clear Job Title

Is it obvious what the position title means from first glance, even for those from outside your company? If it isn’t, this may be because the title is too long or uses confusing terminology.

By carefully optimising your job title, you can come up something short and punchy, but also meaningful that even the most casual reader can quickly understand.

2. Outline What It’s Like To Work For You

Is the ‘vibe’ in your office formal or casual? Whatever your company culture may be, it’s vital to communicate this in the job description.

You may also do this in part by detailing certain specific features of life on your premises, such as morning meetings, team seminars and what travel arrangements are required to get to the office.

3. Stipulate The Daily Duties

Candidates will be able to better visualise what your vacancy is really about if you accurately describe the most mundane everyday requirements of the job.

Also consider what this job’s daily duties are likely to be in the future, so that the eventual recruit is unlikely to be surprised by how the position evolves over the coming months and years.

4. Detail The Most Valuable Skills

What are the skills necessary for this job to be done to the required standard?

If the candidate is well-informed on these, they will be able to compare them to their own skills and consider whether they are a truly suitable candidate for the role. This will help to narrow down the list of applicants to only those who are a good match to the position.

5. Explain What Would Represent The Greatest Success

You won’t want the person that you eventually hire for this position to be merely ‘good enough’, so it makes sense to precisely describe what would constitute particular success in the role.

5 Must-Know Time Management Tips

Effective time management is crucial for personal and professional success. By mastering time management strategies, individuals can enhance productivity, reduce stress, and achieve their goals efficiently. This article explores five essential time management strategies to help individuals optimize their time and maximize their potential.

Set Clear Goals and Priorities
The foundation of effective time management lies in setting clear, achievable goals and identifying priorities. Begin by outlining short-term and long-term objectives, both personally and professionally. Break down these goals into smaller, manageable tasks, and assign priorities based on urgency and importance. By establishing clear objectives, individuals can focus their time and energy on activities that align with their overarching goals, minimizing distractions and maximizing productivity.

Create a Structured Schedule
A structured schedule is a fundamental tool for effective time management, especially for those undergoing PMP training. Allocate specific time blocks for different tasks and activities, ensuring a balance between work, personal commitments, and leisure. Incorporate breaks into the schedule to prevent burnout and maintain focus throughout the day. Utilize digital calendars, planners, or time management apps to organize tasks and track progress. By adhering to a structured schedule, individuals can maintain discipline and accountability, making efficient use of their time.

Practice Time Blocking
Time blocking involves dedicating uninterrupted periods to specific tasks or projects. By segmenting the day into distinct blocks of time, individuals can concentrate fully on one task without distractions. Allocate blocks of time for essential activities such as email management, meetings, and creative work. During each time block, focus solely on the designated task, avoiding multitasking and external interruptions. Time blocking enhances productivity by promoting deep work and minimizing time wasted on context switching.

Utilize Technology Tools
In the digital age, numerous technology tools are available to assist with time management. Utilize productivity apps, such as task managers, project management software, and time tracking tools, to streamline workflow and enhance organization. Take advantage of features like reminders, notifications, and synchronization across devices to stay on top of deadlines and commitments. Additionally, leverage automation tools for repetitive tasks, freeing up time for more critical responsibilities. By harnessing the power of technology, individuals can optimize efficiency and productivity in their daily activities.

Implement the Pomodoro Technique
The Pomodoro Technique is a time management method that involves breaking work into intervals, typically 25 minutes in duration, separated by short breaks. During each Pomodoro session, individuals focus intently on a single task, aiming for maximum concentration and productivity. After completing a Pomodoro, take a short break to rest and recharge before starting the next session. After completing a set number of Pomodoro intervals, reward yourself with a more extended break. The Pomodoro Technique promotes sustained focus, combats procrastination, and prevents burnout by balancing work and rest periods effectively.

Mastering time management is essential for achieving personal and professional success. By implementing these five essential strategies—setting clear goals and priorities, creating a structured schedule, practicing time blocking, utilizing technology tools, and implementing the Pomodoro Technique, individuals can optimize their time, enhance productivity, and achieve their goals more effectively. Incorporating PMP certification training into their schedule can further refine their skills and boost their project management capabilities, enabling them to take control of their schedules and unlock their full potential.
