Comments
This APAR provides guest support for the guarded-storage facility that was introduced with the IBM z14 (D/T3906). This facility is designed to improve the performance of garbage-collection processing by various languages, in particular Java. The guarded-storage facility is a hardware feature aimed at reducing pause times in systems with automated memory management, for example a Java virtual machine's garbage collector. Pause times are phases during which application execution is suspended so as to avoid potential data integrity issues, and can have an impact on an application's response time and service level agreement requirements.
