Hewlett-Packard (HP) plans to acquire business transactions-monitoring software vendor Bristol Technology.HP announced Monday that it has signed a definitive agreement to acquire Bristol as a way to beef up its business technology optimization (BTO) product offerings. The vendor didn\u2019t reveal the financial terms of the deal.Bristol\u2019s TransactionVision software helps customers monitor complex business transactions ranging from insurance claim processes to product orders and inventory management. Users can manage processes running on J2EE or .Net application servers as well as processes running on mainframes.With Bristol under its belt, HP said it will be better positioned to provide users with end-to-end management of their real-time business transactions and extend its HP Business Availability Center business service and application management software to the mainframe.HP and Bristol are already partners. Bristol\u2019s TransactionVision software is integrated with HP\u2019s Business Availability Center and its Universal Configuration Management Database (CMDB) software, both of which were products HP acquired when it purchased Mercury Interactive last year.As part of an ongoing company-wide restructuring effort designed to make the vendor more competitive and efficient, HP has been revamping its software business, creating a number of focused units. In December, following the completion of its US$4.5 billion acquisition of Mercury, HP created a BTO unit to bring together Mercury\u2019s application management software with HP\u2019s OpenView systems and network management technologies.Founded in 1991, privately held Bristol has its headquarters in Danbury, Conn., and the majority of its customers are financial services and insurance companies in the United States\u00a0and the United Kingdom, including JPMorgan Chase & Co. and Blue Cross Blue Shield of Florida.Bristol started off as a provider of cross-platform development tools with its Wind\/U offering, which is still in use, for porting Windows applications to Unix and Linux. In 1998, the vendor began to change its focus to also encompass enterprise software.Subject to closing conditions, HP expects to complete the acquisition within the next 30 days. At that point, Bristol will become part of the HP Software unit inside the vendor\u2019s technology solutions group.-China Martens, IDG News Service (Boston Bureau)Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
