Improving client host performance
Examining and adjusting MVFS cache size
DevOps Code ClearCase® hosts that use dynamic views might benefit from MVFS cache tuning. Default MVFS cache sizes scale automatically based on host memory and are appropriate for a wide range of client needs, but you might want to change default MVFS cache sizes to improve performance in specific cases after performing a performance evaluation in your environment.
MVFS caches in Solaris zones
On a host that is running a version of the Solaris operating system that supports zones, special tools and procedures apply when working with MVFS caches in a non-global zone.

MVFS caches in Solaris zones

On a host that is running a version of the Solaris operating system that supports zones, special tools and procedures apply when working with MVFS caches in a non-global zone.

On Solaris 10 or 11, zones are a virtualization technology that provides isolation and a secure environment for applications. The global zone is the initial zone of the Solaris 10 or 11 operating system. Non-global zones and branded zones provide virtual operating environments in which applications can run as though they were installed on a separate host.

Getting MVFS cache statistics for a zone

To access MVFS cache information and statistics for a zone, you can use these DevOps Code ClearCase® commands and utilities while logged on to that zone:

cleartool getcache -mvfs
ccase-home-dir/etc/mvfscache
ccase-home-dir/etc/mvfsstat
