Recently, there has been some debate on which strategy is better. Although previous work has shown that in a failure-free environment, the CL algorithm performs better than the DL version, there are still some doubts about the performance of the CL algorithm in an environment where failures could occur. Thus, in this paper, the performance of a resilient CL algorithm is compared with that of a resilient DL algorithm in an environment where site failures could occur. The results show that the resilient CL algorithm still outperforms the resilient DL algorithm in terms of mean response time of transactions, resource utilization and communication cost. In addition, it is shown that the reliability of the resilient CL algorithm is improved considerably and is comparable to that of the resilient distributed version when an election protocol is used to rapidly elect a new central site whenever the central site fails.","PeriodicalId":415748,"journal":{"name":"1986 IEEE Second International Conference on Data Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122590023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is in contrast to a data sharing multi-system approach in which all systems have direct access to the shared database. The performance of the function request shipping approach is examined and compared with the data sharing approach. The emphasis is on generic issues that affect the function shipping approach. Trace data from large mainframe systems running IBM's IMS database management system are used to illustrate the issues of partitioning. A methodology is presented for partitioning the databases and routing transactions among the systems so as to minimize the fraction of remote function calls, while balancing the load among systems. Estimates of the resulting remote function calls, mirror transaction setups, and multi-system two-phase commits, are obtained. A simulation model and approximate analysis are used to examine the overall system performance, to study the effect of various workload parameters and design alternatives and to compare the function shipping and data sharing approaches.","PeriodicalId":415748,"journal":{"name":"1986 IEEE Second International Conference on Data Engineering","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126088046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
