To match up same there was ahuge intensive cooperation with in team. The completedevelopment process encompasses different time space,different locators like internal or external and betweenspecific as well as specialized workgroups. Hence it was mustto answer questions pertaining to questions related to divisionof labor, to communication, and to coordination andcooperation in the planning, development and maintenance ofsoftware systems. Development environments that explicitlysupport group work are an important prerequisite for theproduction of high-quality software systems.KeywordsSoftware Dependencies, Application Monitoring,operation difficulties.

INTRODUCTIONThis paper presents the Use Case for identification of rootcause of the dependencies and mutual understanding and cooperation difficulties in on software systems and to find a newunderstanding of the dependencies that exist in softwaresystems. This would equally help to answer the question ofSoftware developers that ―How to use practices andtechnologies to manage them.‖ and provide deep insight ofthe root cause of the dependencies, since all software systemshave dependencies because software modules interact witheach other, with documentation, with libraries, and with testsuites. J. Michael Moore, Frank M. rightly analyses that theSoftware development includes gathering information abouttasks, work practices and design options from users [10].Software engineers recognize that these dependencies exist, astechnical relationships between the components of the system,and have tried to model them as part of their formal methodsand process descriptions. For this study we have opted mostsuccessful Application Monitoring Tool ―CA WILY‖provided by the internationally acclaimed OEM ComputerAssociates (CA). The software module was implemented bythe OEM implementation partner ALCEL Networks Pvt. Ltd.for the customer is Technocraft Consultancy Sales andServices (TCSS).1.1 A Brief Overview of USE CASEExecutive SummaryTo assure critical revenue and optimal performance of CentralBoard of Excise and Customs (CBEC) applications, TCSSrequires an application management solution that can monitor100% of user transactions, provide unique data on thebusiness impact of failed transactions, and deliver essentialdata for resolving problems quickly – all with negligibleoverhead. With such a solution in place, everyone in theorganization — Line of Business managers, applicationadministrators, architects, DBAs, IT app owners, etc. canwork together to ensure customer satisfaction, SLAcompliance, and business success.CA Wily provides deep visibility into the applicationenvironment and helps enterprises keep their mission-criticalapplications high-performing and available 24x7. This abilityto proactively monitor end-to-end transactions of all users inreal time and provide deep visibility into the application – allwith negligible impact on application performance - separatesWily from all other vendors in the industry.CA Wily seeks to enhance the functioning efficiency amongstTCSS, its SI vendors, and government IT providers, in orderto help evolve into an efficient IT Center of Excellence.Understanding the RequirementsAs per understanding, currently Customs has 4 criticalapplications out of which the current scope is limited toimplement an integrated end to end Application PerformanceManagement solution for comprehensive ACES applicationdeployment.Within the ACES application, followingmodules have been included:-CEDEPT-STASE-REGASESTDEPTTo date our knowledge of requirements and the driving forcesbehind this initiative are based on the following: Deployment of Wily into ACES productionenvironment during POC10

The only client software requiredis web browser. The appliance ships with sufficient storageto maintain historical data. The data gathered can beexported to any relational database you choose, but there areno requirements for database licensing to support the CAWily solution. All of the above on 42 cores (21 CPUs) across 2clustered instancesApplication Performance/ WebManagementCA Wily is an application management solution that canmonitor 100% of end-user transactions happening in a TCSS,provide unique data on the impact of failed transactions, anddeliver essential data for resolving problems quickly – allwith negligible overhead. With such a solution in place,everyone in TCSS —application owners, network owners,departments, etc. can work together to ensure SLAcompliance and end-user satisfaction.CA Wily provides deep visibility into the applicationenvironment and helps TCSS keep their mission-criticalapplications high-performing and available 24x7. This abilityto proactively monitor end-to-end transactions of all users inreal time and provide deep visibility into the application – allwith negligible impact on application performance - separatesWily from all other vendors in the industry.CA‘s Wily Technology offers the only comprehensivesoftware and services solution specifically designed to ensureeffective Customer Success Management (CSM) by offeringunparalleled visibility into customer transactions and webinfrastructure performance.CA Wily Customer Experience Manager (CEM) providesreal-time views and proactive alerts that enable you toimmediately respond to the online experience of eachapplication end user, detect transaction problems as theyhappen, and ensure transaction integrity.CEM monitors every transaction in real time, analyzing theperformance and quality of web-enabled business processes.When problems with real or synthetic transactions occur,CEM provides detailed analysis on the scope, severity, andimpact of the transaction defects. CEM enables you toidentify, prioritize and resolve defective transactions —often before they impact users — through real-time visibilityinto transactions. By measuring performance from theTIM (Transaction Impact Monitor): The TIM is nonintrusive appliance that resides in the data centre, connectedto a mirrored switch port or a network tap. The TIMpassively listens to all network traffic and analyzes only thetraffic of interest. Using patent-pending software, itassembles data packets into unique business transactions.TIM applies business rules to detect customer-impactingdefects and anomalies, and reports real time and historicalinformation about customers and transactions to a centralrepository.The TIM‘s primary functions are to: Observe a packet stream. CEM uses a copy of thenetwork traffic using a span or mirror portresulting in zero network utilization. Identify transactions and users Monitor transactions for defects and intervalstatistics regarding behavioral characteristics liketime, size and throughput. Upload the defects and interval statistics to the(TESS)Transaction Event and Statistics Server (TESS): TheTESS runs the Wily CEM Software Modules. The TESScommunicates with one or more TIMs and is accessedthrough any browser. It receives real time alerts (events)and performance and quality statistics from one or moreTIMs, allowing IT personnel to collect metrics centrallyfrom various applications. The TESS is what allows ITteams to analyze, aggregate, and present real time andhistorical data, creating views, reports, and scorecardsfor incident resolution, continuous improvement, andexecutive reporting. The TESS is a combination ofbackground processes, application logic, an SQLdatabase and a Web serverThe architecture of the CEM has been designed to scaleas your environment grows. The architecture providesfor scalable growth through the addition of TransactionImpact Monitors as needed. Multiple TIMs can be usedto report to one TESS. TIMs can be distributed acrossdifferent data centers.11

Thisrequires a proactive detection andnotification system.Once a problem has been detected,application support personnel need toquickly and reliably determine whereto assign the fix. Effective triageeliminates the chaos of the blamegame and finger pointing.Javadevelopersandsystemadministrators need timely, accurateinformation about the source ofperformance problems so that theseissues can be resolved with minimalimpact on IT resources.Historical data capture gives IT andthe Business Units it serves theinformation they need to effectivelymanage and maintain service levels. Italso allows capacity planners toanalyze trends over time and plan forfuture needs.CA Wily Introscope is an application management solutionthat helps TCSS to keep the mission-critical web-based J2EEand .NET applications high performing and available 24x7. Itcombines proven technology, scalability and ease-of-use tooffer the very best means for monitoring and managingcomplex, composite applications. It ensures that applicationsare successfully achieving required SLAs and otherperformance goals. Introscope is the cornerstone of acomprehensive collaborative application managementsolution that helps TCSS increase application resiliency,minimize the impact of application performance issues andimprove total cost of ownership.Introscope agents collect performance metrics from thevarious components inside the running Java / J2EEapplication, the application server and performance andavailability data from the surrounding computingenvironment. The agents then report these metrics to theEnterprise Manager. No change to your source code isrequired. Out of the box (i.e. no configuration), Introscopeagent will monitor EJBs: (Entity, Session, and Message-driven asapplicable) JSPs Servlets JDBC JNDI Network Sockets RMI XML JTA JMS CORBA UDP File I/O Socket I/O CPU ThreadsIn addition, GC Heap Bytes in Use, GC Heap Bytes Total,Java Version, Launch Timestamp, VM Vendor, IP Address,Operating System, and Wall clock Time are all monitored―outside‖ the Java VM.The Introscope Enterprise Manager acts as the centralrepository of all Introscope performance metrics. It receivesperformance metrics from one or more Introscope Agents,allowing users to collect metrics centrally from manyapplications, application servers and supporting systems.Introscope includes out-of-the-box reports for applicationperformance analysis, capacity planning and Service LevelAgreement administration, which make it easier to trackapplication performance over time and plan for future growth.Introscope provides the breakdown of individual usertransactions displaying precisely what exception was thrownand where the exception was thrown from (essentially the callstack). When viewing a faulty transaction in TransactionTracer, one can easily identify precisely where the exceptionis being generated from.DEPLOYMENT ARCHITECTUREFig 1: Deployment Architecture12
