You can reset the cache size without rebooting a machine. The value remains in effect until you next reboot the machine. To change the cache size temporarily, do the following:
1. Log in as root on the machine.
2. Issue the cm setcachesize command to set a new cache size:
# cm setcachesize -size kilobytes
The -size kilobytes option is the number of kilobyte blocks to be used for the cache. A value of 1024 equals 1 megabyte; the smallest allowable value is 1. A value less than 5120 (5 megabytes) can have a negative effect on Cache Manager performance; a value less than twice the chunk size is rounded up. A value of 0 (zero) resets the cache size to the amount specified in the CacheInfo file.
