As every CIO knows, customer service expectations continue to rise while mainframe IT budgets are coming under increasing pressure. That makes it imperative to keep your business-critical z/OS applications performing at the highest level and minimize their use of costly processor capacity.
Designed specifically for z/OS systems, FreezeFrame is a performance analysis solution that pinpoints application problems through detailed observation and provides comprehensive system information to help you find the cause of the badly performing code.
FreezeFrame can be used on its own or in combination with ExpeTune, which identifies candidates for observation by FreezeFrame and provides expert tuning guidance.
FreezeFrame uses observation sessions to measure how system resources are used by applications in the z/OS Sysplex environment. During a session, FreezeFrame can sample activity in any target address space at any frequency and duration, resulting in a series of snapshots that map observed system states to system objects. These snapshots are then aggregated to produce performance analysis reports which provide a meaningful picture of how resources are consumed and highlight slow or improperly running programs.
