33.5 Reconfiguring a View

Use setcache to reconfigure a view_server's cache to a new size. The ratio of memory allotted to each subcache is fixed. When specifying a cache size, keep the following guidelines in mind:

• The value cannot be smaller than 50 KB for 32-bit platforms or 100 KB for 64-bit platforms.

• Do not specify a value larger than the amount of physical memory on the server host that you want to dedicate to this view.

• Larger cache sizes generally improve view performance, though as cache sizes approach 4 MB, the performance improvement usually becomes less noticeable.

• Verify your changes by checking the hit rates and utilization percentages periodically to see whether they have improved.

To specify a new cache size for a single view, use the setcache -view command:

cleartool setcache -view -cachesize nnn view-tag

Note that you must be the privileged user or the view owner to use this command. See the setcache reference page for details.
