Hewlett-Packard plans to acquire business transactions monitoring software vendor Bristol Technology.

HP has signed a definitive agreement to acquire Bristol as a way to beef up its business technology optimisation (BTO) product offerings. The vendor didn't reveal the financial terms of the deal.

Bristol's 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.

HP said it would now 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's TransactionVision software is integrated with HP's Business Availability Center and its Universal Configuration Management Database (CMDB) software, both of which were products HP acquired when it bought 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, HP created a BTO unit to bring together Mercury's application management software with HP's OpenView systems and network management technologies.

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's Technology Solutions Group.
