Database Administration

Question: Discuss about theDatabase Administration. Answer: Generation of a Real Life Scenario using Dedicated and Shared Server Figure 1: Dedicated and shared server system (Source: ORACLE - DBA Tips Corner, 2016) The database administrators are facing a problem regarding the increased number of connection and their databases. The most of the system are using the traditional method i.e. the dedicated server that processes the request of the client. Sometimes the server processes are called shadow process, the process consumes memory for each process, and thus more memory is required for more number of connections (ORACLE - DBA Tips Corner, 2016). If we think of system, with five clients that accesses the database and if a dedicated server is used the 4 dedicated servers are required for processing the request at a time and if each process takes 8 mb of memory then 32 mb of memory would be required for the scenario. However, if the user increases to 100 then 800 mb of memory would be required but using shared server the client can be handled using two shared server processes. When the user spend time in editing the data and less time in fetching sql query from the database an OLTP environment i s created. In this case, the dedicated servers sits idle consuming the memory of the server. Multiple thread servers can share the server process between the clients and increase the efficiency of the system (Bryla Loney, 2013). The multiple thread servers can also manage the situation where the client continuously connects and disconnects the database. Thus in most of the places like in office environment more number of shared servers are used along with a dedicated server that manages the shared servers. The shared servers can be increased with the increase in the demand and the extra servers are deleted when the demand decreases. List of all default path used in Oracle folder Install-path- It represents the installation directory for the directory server enterprise edition of the software. The software is installed in the below directory of the install-path. E.g. the directory server is installed in install-path/ds6/ (Jashnani et al., 2014). E.g: when the installation is made from a zip file the install-path is the current-directory/dsee7 and when the installation is made from a native package the default installation-path is /opt/SUNdsee7 Instance-path- It represents the full path for an instance of Directory Proxy Server or Directory Server. E.g: The instance path is nevertheless found on a local file system. On Solaris system, the /var directory is used. serverroot- It represents the parent directory of the Identity Synchronization for location of the windows installation (Reed Acar, 2013). E.g: It depends on the installation and the concept of the serverroot does not exists on the Directory Proxy Server or the Directory Server isw-hostname- It represents the Identity Synchronization for instance directory in windows Eg: It depends on the installer /path/to/cert8.db- It represents the file name and default path for the client certificate database for Identity synchronization in windows. E.g: current-working-dir/cert8.db serverroot/isw-hostname/logs/- It represents the default path of the Identity synchronization for the local log files in windows for the system manager, central logger and each connector (Jashnani et al., 2014). E.g: It depends on the installer serverroot/isw-hostname/logs/central/- It represents the default path of the Identity Synchronization for the central logs of windows. E.g: It depends on the installer Figure 2: Logical Storage structure in Oracle (Source: Created by author) The above diagram represents the logical storage structure used in Oracle and the sizes are represented in blocks for the each part. The database of the oracle stores data in blocks and one logical data block represents the specific number of bytes of the physical disk space (Greenwald, Stackowiak Stern, 2013). The data blocks are the smallest storage units that the Oracle database can allocate or use. The extent represents the set of logically contiguous data blocks that is allocated for the storage of the specific type of information (Bryla Loney, 2013). The segment represents the set of extents allocated for a specific object of the database, such as a table. E.g: the data of the employees are stored in the own data segment, whereas the index of the employees are stored in its own index segment. References Bryla, B., Loney, K.

Juvenile Offenders Essays - Criminology, Childhood, Crime

Juvenile Offenders Juvinile Should Juveniles be waived to adult court Philosophy 14 Nov 98 Should juveniles be waived to adult court. There has been tension between teens (pre-teens) and adults for thousands of years, and the question how to deal with the youth of a culture, in a punishment sense, has been with us for just as long. Socrates, for example, stated that children show little respect for there elders. Since Socrates time largely due to the spread of guns and drugs, younger and younger children are committing violent crimes. Children that have special needs or have committed a criminal act have been subject to state protection since, 1838. The first juvenile court was established in Chicago in 1890. The assumption, that was made at that time, was that the criminal justice system should work to help youngsters, not to humiliate or punish them. Along with the creation of the juvenile justice system went the creation of status offenses, these are offenses that if committed by an adult, would not be consi dered an offense. In the 1950's and 60's many laws were passed to protect the rights of children, in a court of law. The major decisions of this time were: Kent v. United States, In re Gault, and In re Winship. Since the time that these laws were enacted, the number of juveniles committing violent offenses has risen dramatically. There are two distinct schools of thought in this argument: side A believes that a persons age should not prevent that person from feeling the full effect of the adult court system, while side B feels that you simply cannot apply the same rules to juvenile offenders that you do to adults. I will first present side A's case then B's and finally end with my own opinion. Many states have begun enacting new laws about the transfer of juveniles, that are more harsh on juveniles. Minnesota, for example, has a new law that states a 16 or 17 year old person that has been charged with a violent offense has to prove to court why they should be tried in the juvenile s ystem. In cases where the offender is younger than 16 the prosecutor must show why the juvenile should be waived. One of main issues of side A, is that if the offender is too old the sentence would not be severe enough for the crime that had been committed. Another issue is the overcrowding of the juvenile justice system. Many of the offenders in the juvenile system, if a few years older, would have already been sentenced to life sentences in an adult court. Side A does not believe that a persons age should be the lone determining factor for non-waiver. While side A does believe that there are a great many negative influences on today's youth, they believe that these circumstances do not dismiss that crimes that have been committed. The core belief that most of the side A advocates share is, the belief that the small percentage of the juveniles that are committing the serious crimes are past the point where a juvenile court could be of any help. Side A truly feels that by allowing s erious juvenile offenders to be waived to adult court, thus receiving a stiffer sentence, the community, as a hole, will be much better served. Side B believes, essentially, that no child (juvenile) should be waived. Side B sees several key factors for the rise in juvenile crime. These reasons are ones that are out of the control of the juvenile. The key factors are: (a) Unemployment among teens was 19 percent in 1993, up from 15.3 percent five years earlier, and for black youths the unemployment rates were twice that. (b) Since 1970, Aid to families with dependent children benefits have declined an average of 45 percent in inflation-adjusted dollars, according to the Children's Defense Fund. (c) In 1992, there were 14.6 million children living below the poverty line, the Children's Defense Fund says, about 5 million more than in 1973. (d) In 1993, there were 3 million victims of child abuse, according to the National Committee for the Prevention of Child Abuse- a rate 50 percent hi gher than in 1985.

Econometrics Assignment Example | Topics and Well Written Essays - 500 words

Econometrics - Assignment Example For RM (average number of rooms in the owner occupied housing in the census tract), in the first variant, a 1 percent change in RM causes 0.329 % change in MV (the median housing price). In the second variant, a 1 percent change in RM causes a 0.0306 % change in the median housing price (MV). Eventually, a 1 percent changes in RM causes a 0.294 % change in the median housing price in the third variant. In the second variable, the weighted distance to five major employment centers in the Boston region (DIS), the order of coefficients; 0.028, 0.027, and 0.027 in absolute values. In the criteria of absolutism, a one percent change in DIS causes a reduction of median housing price by 0.028 in the first variant, a reduction of 0.027 in the second variant, and a reduction of 0.027 in the third variant. In the third variable, nitrogen oxide concentrations in parts per hundred million (NOX), the coefficients are 1.479 and 1.529 in the second and third variants respectively. These figures suggest that 1 percent change in nitrogen oxide concentration increases the medium housing price by 1.479 in the second variant and by 1.529 in the third variant. Beta coefficient is the measure of the sensitivity of the estimates in influencing the median housing price. In the estimates, the beta coefficient is the slope of the model summarized into ÃŽ ²0, ÃŽ ²1, ÃŽ ²4, ÃŽ ²3, and ÃŽ ²2. Normally, the coefficients would imply 1 percentage change in the estimate 1 and 2 would cause an increase of 0.566 and 0.0261. However, using the beta approach, the two coefficients are below, suggesting that they are below the median housing price. 6. Suppose in model (3) I added in the variable NOX DCHAS, resulting in ln(MVi) = ÃŽ ²0 + ÃŽ ²1RMi + ÃŽ ²2 ln(DISi) +ÃŽ ²3NOXi + ÃŽ ²4DCHAS;i + ÃŽ ²5 NOX DCHAS +Æ i . How would the interpretation of Æ 3 change in model (3) after the inclusion of this variable? What is the interpretation of Æ 5 in this model? 9. Given

Terrorist Scene & Aftermath Essay Example | Topics and Well Written Essays - 500 words

Terrorist Scene & Aftermath - Essay Example Terrorist attacks could be planned or completely disorganized, but it is always good to presume that any terror attacks have organized traps for the first responders. This aspect calls for extra carefulness for who should or should not take the first response step (Weiss, 2001, pg.117). First responders do not always find their actions rewarding. In some cases, terrorist ambush those willing to take first action by shooting at them, planting bombs in unexpected locations, trapping them within buildings, or making them appear like they were among the terror attackers among other dangers and traps. Some terrorist attacks however may not need to be planned for the dangers to be high. Attacks made using radiological dispersion devices are generally dangerous for first responders who may lack the expertise to detect harmful radiations (Runge, 2009, pg. 407). The invisible radiations in this regards could be part of the dangers and traps arising from a well-planned terrorist attack of such kind. In the case of terrorist attacks, hospitals within the locality are likely to be interrupted since they are faced with the obligation of accommodating the injured victims. In order for hospitals to avoid adverse interruptions, they should prepare a disaster plan to prepare for major influxes of injured individuals after terrorist attacks. This plan for enhancing preparedness should include an effective plan for handling the deceased especially in worse case situations (Lowe & Hummel, 2014, pg. 211). The preparedness plan may include contingencies that would encompass the hospital’s strategy. The hospital can also adopt the plan to include further actions such as handling victims of terrorism attack earlier even before arriving at the hospital. This could be done like the case of many hospitals that have already implemented plans for handling victims of

Fishbone Diagram Essay Example for Free

Fishbone Diagram Essay Fishbone diagram allows Hotel Escargo to turn the problem upside down working through the roots so that the issue is fixed. It is also easier to fix the smaller problems that lead to the main problem. Looking at the check-in delays, there are a lot of small issues that have led to this occurrence. The first issue is computer malfunctions. Often times, computers tend to freeze due to glitches in the used software causing them to lose customers entering information. This issue causes customers not to get their room which is a check-in delay. Another issue is not having valid and filed credit cards. When checking in, some customers enter the hotel with credit cards that are either expired, maxed out, or not in service. This leads to customers not being able to check-in their room which is another check-in delay. Not having rooms prepared for guests because of a slow cleaning crew leads to check-in delays. Having no available bellmen due to them assisting other customers also leads to check-in time delays. This results from having a shortage of bellmen. Bad front desk service due to them being slow, unorganized, and having a shortage of workers leads to check-in delays. Last but not least, not having a pre-reserved room also leads to check-in delays because individuals have to go through the reservation process the day they try to get a room. If all of these issues are taken care of, check-in delays will be eliminated.
