Flag note k

I often get mails from people asking what are the questions generally asked in Weblogic by interviewers. Generally for an Administrator’s positions, in addition to Weblogic questions, there are a lot of Unix questions and a few questions related to process and case handling. These are the important questions that I cover while interviewing. 1. How do you differentiate between a server hang and server crash issue? When a Server crahes, the JAVA process no longer exists. When the Server is hung, it stops responding. We can use the weblogic.ADMIN utilty to ping the server. In case of a hang situation we can take multiple thread dumps and analyze the cause of hang. 2. What can be the various reasons for a server crash? a) Native IO b) SSL Native Libraries c) JVM d) Supported Configuration e) JDBC Driver issue 3. How do you troubleshoot a crash? JVM crash generates a hs_err_pid file. We need to look into the stack trace of the hs_err_pid file . If the thread is from a native io, we need to disable native io. if the stack trace is from the driver, we need to get in touch with the drive team. Quite possibly its a problem with driver. Changing the type of driver can be a workaround. If the thread shows it coming from an optimzed code, we can turn of optimization. If the stack is from native calls of application, its a bug with the application and it has to b modified. 4. Ho do you troubleshoot Server Hang? We can use java weblogic.Admin PING to check if we get a normal response. We need to take multiple thread dumps with kill -3 pid on unix and CTLR Break on Windows. Analyze the thread dump to find the root cause. 5. What can be the reasons of Server hang? Memory leak, databse query taking a long time to return, Deadlock. 6. What is memory leak? Memory leak is when objects are not romved from the heap even when they are not required. 7. What are the various causes for OUT OF MEMORY? a) Insufficient heap size, not able to match the extra load. b) Objects licing too long, like HTTP Sessions. c) Memory leak in application code. d) Full GC not happening due to JVM Bug. 8. How to troubleshoot and overcome such issues? Gather memory data by enabling GC verbose. If its due to Http Session, timing out http session after certain interval might help. Look into the code for jdbc connection handling. Optimizing the heap size according to the load. 9. When does High CPU Usage occur? It occurs when one process or one thread utilizes unexpectedly high proportion of CPU. 10. How to troubleshoot it? In Solaris environment, we need to take pstack and prstack and see what the threads are doing. In Windows we need to use pslist and process explorer. 11. What is Clustering and what is achieved through it? Clustering is the grouping together of servers for the purpose of high availability and scalability. Load balancing and Failover is achieved. 12. How does Cluster Communication Happen? Members of the Cluster communicate over the Cluster Multicast IP and Port by sending periodic heart beat messages. 13. What is the difference between the Sun JVM and BEA JRockit JVM? The most well know JVM is the implementation from Sun. The Sun JVM is called HotSpot. The Sun JVM is shipped in the Java Developer’s Kit (JDK) and Java Runtime Environment (JRE) from Sun. The BEA JRockit JVM from BEA systems is optimized for reliability and performance for server side applications. To achieve this, BEA JRockit JVM uses technologies such as code generation, hot spot detection, code optimization, advanced garbage collection algorithms and tight operating system integration. 14. TUning JVM Parameters. If you have a single processor, single thread machine then you should use the serial collector (default for some configurations, can be enabled explicitly for with -XX:+UseSerialGC). For multiprocessor machines where your workload is basically CPU bound, use the parallel collector. This is enabled by default if you use the -server flag, or you can enable it explicitly with -XX:+UseParallelGC. If you’d rather keep the GC pauses shorter at the expense of using more total CPU time for GC, and you have more than one CPU, you can use the concurrent collector (-XX:+UseConcMarkSweepGC). Note that the concurrent collector tends to require more RAM allocated to the JVM than the serial or parallel collectors for a given workload because some memory fragmentation can occur.

BBA-LLB BA-LLB Direct Admission through NRI/management quota 2016 in Bangalore Pune & Mumbai ||Call: +91-9916566036 For any query regarding MBBS BDS B.tech B.E. UG Engineering BBA MBA BBM Bcom BA (LLB) BBA (LLB) LLM BCA MCA admission through management quota|| ||If you want to become a law graduate , Call: +919916566036 || There are essentially two routes that are available for you to become BBA-LLB BA-LLB law graduate. One is to take up the 5 years integrated BA LLB or to take up 3 years LLB after completing graduation in any stream. Here we are comparing the two options so that the takers can make an informed decision. Duration: Both these courses lead to a law degree eventually but LLB after graduation takes in all 6 years; therefore many students opt for integrated BA LLB to save 1 year. Option to opt out after 3 years Well, integrated course really makes sense for those students if they are 100% sure that they want to continue only in this particular field, that is the field of Law. This is so because after completing 3 years generally the option to get out is not there in most of the integrated courses, so essentially, if one opts for this option then one has to complete this. Concern of choosing the course again Usually the students have to face two dilemmas; the first one is when one has to choose an option after 12th. The second dilemma comes after completion of the Graduate course. So a big advantage of getting into an integrated BA LLB course is that one is free from the worry of choosing a college and course again after 3 years. This is not the case with those who are doing a normal graduation course. But if you are the one who is not fully sure that career in law is for you (you can know whether law is suitable for you or not by simply taking the MapMyTalent Assessment) or want to keep the option of other professional or higher education options for yourself, then perhaps, a 3 year graduation course would be a good option for you. Availability of seats in reputed College/ University There are many reputed National Law Universities that offer only integrated BA LLB course and then LLM or PG Diploma courses. So there are many seats for 5 years Integrated Course. Other than NLU’s many other universities like Punjab University, AMU, IP University Delhi, etc also offer BA LLB Course. On the other hand LLB is offered at many prestigious central and state universities like Delhi University, Punjab University, BHU, Government law College Mumbai, Bharati Vidyapith, Dr Harisingh Gaur University, MP, Indian Law Society’s Law College in Pune, Punjabi University, Rajasthan University, Law college Dehradun etc., So a large number of seats are available. Also if you have taken admission in a 5 year BA LLB then you have a seat guarantee for 5 years that is you don’t have again look for a seat for admission after graduation. Syllabus As far as syllabus ( Ref Punjab University Syllabus for BA LLB) is concerned since BA LLB is integrated course the students study law papers right from the first semester onwards like Law of Torts, Consumer Protection Laws, Law of contract etc. These law related papers and English is compulsory but the students can choose papers form Political science, History, economics, sociology etc. In the second semester they study Jurisprudence and Special contracts. Like that in every semester there are some papers from the Law field. After 3 years, that is 7th semester onwards the BA papers are taken as major and minor and there are other papers of law like Business law, international law etc. As far as syllabus of LLB is concerned the students takes up LLB after they have already completed their graduation and the course only includes courses from law Jurisprudence, Constitutional Law, Law of contracts, Family Law , Law of crimes etc. Both the courses include summer training and also the students attend court. Degree In BA LLB after 5 years the student gets two degrees one for BA and another for LLB. While in LLB he gets the degree of LLB. Variants The 5 year integrated LLB degree now has many variants also like there are B.Com LLB, B.Sc LLB and BBA LLB is also available. Just like BA LLB integrates Arts subjects with Law the other courses integrate the subjects from the respective fields with law courses.
