Embarcadero Systems is shipping Embarcadero Performance Center 1.9, a version of its multiplatform database monitoring product that adds a web client and management functions for Linux and Unix databases.
The web client allows a DBA to monitor database performance without requiring the company's standard client software to be installed on the system, said Robin Shumacher, vice president of product management at Embarcadero.
Embarcadero's web client is read-only, however, providing data on the status of systems but incapable, for example, of allowing DBAs to set up notifications that would be triggered based on conditions in the database.
Release 1.9 expands OS monitoring to Linux and Unix, including Red Hat and Suse's Linux variants and Unix platforms from Hewlett-Packard, IBM and Sun.
Version 1.9 appears to correct uptime problems that one user had with previous releases.
Ixiasoft, meanwhile, is adding fault tolerance to its Textml XML database. Textml 3.1 features the Textml Fault Tolerance Server, which ensures that two or more servers and Textml Document Bases installed in parallel are synchronised, enabling immediate access to backup servers in the event of hardware failure.
"It's really designed for apps that require zero downtime," such as a large web portal, said Marc Cyrenne, director of business development at Ixiasoft.
Textml enables XML data to be stored in its original format rather than decomposing it for storage in the rows and tables structure of a relational database, Cyrenne said.
