ShikshaTopQuestions-Information Technology

Let me understand your purpose behind asking this question since both the certifications are not in the same domain. While CCNA is an entry level Certification in Networking, OCJP (which used to be SCJP or JCP back in the late 90s.) is a decent Java programming certification. With OCJP you can get a decent job as a programmer with any small to medium sized organization. However, I can't say the same with confidence about CCNA.
Since both certifications are in completely non-related domains, it is really hard to compare both. What exactly is your purpose or intention? What is your ultimate goal? What do you believe you are good at & most importantly, interested in, viz. networking or programming? If problem-solving is your thing, I'd say go for OCJP, but if you are thrilled to work with routers & switches, go for CCNA. Make sure you don't stop after CCNA. You will have to upgrade to CCNP & then later on CCIE.

Set up a full proof study Plan
If you have prepared a comprehensive study plan then it will help the aspirants to achieve their goals. The plan must be realistic and must be according to the daily needs and schedule. Make the plan practical and study at your own pace. The plan must such that it reduces the stress and increase the effectiveness. Candidates must create an awareness about the syllabus, the difficulty faced, availability of time, and the candidate's performance target for the particular exam.
Ladders in preparing for the Exam
Plan your time sensibly. Candidates must divide the study session into different study sittings. The candidates must segment the syllabus into small segments. Lay down clear and specific goals for the learning sessions. Candidates must create an acquaintance with the material and the difficulty level in each section. don't have long study sections. This will increase your stress.
Candidates must select a place where there is less noise and hindrance in the study. You should include enough mixture in terms of topics and activities to put off boredom and loss of efficacy. Candidates must monitor their progress regularly. This can be done by diagnostic or through a practice test. This will help to understand the strong and weak areas.

Hello,
Oracle is a database program. This course is one of the most interesting and challenging course in the database domain. It may or may not be included as a part of the syllabus of degree courses in computers. The best option is to study this course via a certification program provided by any computer training institute. Such institutes provide their own certifications.

Some of these might be popular, some might not be. Some could have a well-built infrastructure, others might not. The key idea is to find a good mentor who can help a student understand the fundamentals of the subject and make the student capable of finding solution to problems.
