To change the cache size permanently, do the following:
1. Log in as root on the machine.
2. Use a text editor to change the number in the third field of the CacheInfo file. Specify a number in kilobyte blocks; 1024 kilobyte blocks equals 1 megabyte. Following is an example of the CacheInfo file:
/...:dcelocal/var/adm/dfs/cache:25000
Caution: Be precise when editing the CacheInfo file. Use colons to separate the fields in the file; do not include any spaces in the file.
3. Reboot using /etc/reboot or its equivalent. (Consult your system documentation for information on the correct rebooting command for your workstation.)
