Thus, the maximum CLM on any cell is 48 GB and the total ILM in the system is 32 GB. Find the minimum
granule size using the vparenv command:
# vparenv
vparenv: The next boot mode setting is "vPars".
vparenv: The ILM granule size setting is 512.
vparenv: The CLM granule size setting is 512.
vparenv: Note: Any changes in the above settings will become effective
only after the next system reboot.
vparenv: Note: The maximum possible CLM granules per cell is 256.
vparenv: Note: The maximum possible ILM granules for this system is 1024.
The example system is already in vPars mode. Its current granule size is 512 MB for both ILM and CLM. The
maximum number of CLM granules per cell is 256 and maximum number of ILM granules is 1024. Dividing
the memory size by the maximum number of granules yields 192 MB for CLM (48 GB divided by 256) and 32
MB for ILM (32 GB divided by 1024). Hence, you can use 128 MB as minimum granule size for ILM and 256
MB as the minimum granule size for CLM. To create a new database called vpdb.new with ILM and CLM
granule size of 128 MB and 256 MB respectively and update the firmware as well, issue the following
command:
# vparcreate -p vpar1 -D /stand/vpdb.new -g ilm:128:y -g clm:256:y ...
