High-performance academic information systems and high availability services are requirement in every university. One of many reasons is for anticipation damage and fail server disrupting server network performance. Failover computer cluster method is applied to two servers: primary server as main server and secondary server as backup server. Four stages will be carried out: First: Installation and support software configuration. Second: installation and failover cluster configuration. Third: installation and Distributed Replicated Block Devices (DRBD) configuration. Forth: server testing with siege and nettool. This research conducted by doing server test before and after high availability. As if the main server has a system failure, it will automatically backup the main server to backup server to minimize user accessed data failures. System uses Ubuntu 16.04 LTS operating system. Based on the test data, it is acquired two data: packet data and data response time (ms). Data packets acquired from this research are: 233.3 average data sent; 228.3 average data received; 2.3 average data lost; while 59.7 average response time (ms) is showed; 2.7 minimum average; 633.8 maximum average. Data sent is 120B per data.
Abstract— Implementation is one of phases in Software Development Life Cycle (SDLC). Programmer as software development lead actor decided whether software is completed on time or postpone according to development schedule. Data Warehouse and IT Center (PTIPD) as a software developer official vendor in UIN Sunan Kalijaga, they developed a growing number of software to facilitate administrative processes in college academic community. This is an analysis to determine the factors that most influence the developers. The object of this research are 9 (nine) people. They are all software programmer in PTIPD. The research using Mixed Methods Research that combines two methods of research, qualitative and quantitative. Two factors from previous research are factors materialistic and non-materialistic factors. Materialistic factors are Reward and Punishment; Career Development and Contra-Accomplishment, Incentive and Bonus. Non-Materialistic factors are: Usefulness; Relationships and Spirituality. Preliminary data taken from interviews, observation and documentation study to discover object opinions and views. Validity Test and Reliability Test using SPSS software for qualitative data is provided. The most influence factor for programmer performance SDLC of PTIPD UIN Sunan Kalijaga is Usefulness with the highest value at 3 (three) informant: Oscar, Bravo, Mike and Relations with the highest value at 3 (three) informant: Delta, Sierra, Zulu . Keywords: Career development, programmer performance, relationship, sequential explanatory, mixed method research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
