complex must not exceed the TiCAP bought for the complex.
TiCAP commands
Assigning TiCAP to a partition
TiCAP is assigned to a partition using the following command:
icapmodify –B [<numberOfMinutes>| <xxdyyhzzm>]
Sample Output:
# icapmodify –B 240
Temporary capacity available: 0 days, 4 hours, 0 minutes(240 minutes TiCAP )
This assigns 240 minutes of TiCAP for the partition.
NOTE: TiCAP is assigned in terms of minutes. It can also be specified in the ‘xxdyyhzzm’ that is
for ‘xx’ days,’yy’ hours and ‘zz’ minutes. Only positive balance are allowed , that is the TiCAP
balance cannot be set to negative.
Decrementing TiCAP assigned to a partition
The amount of TiCAP assigned to a partition can be decreased by using the following command:
icapmodify –I <negative_number>
IMPORTANT: 30 minutes of TiCAP is reserved for each core currently using TiCAP. So during
decrement of TiCAP , the operation is not allowed if the above condition is not met.
Sample Output:
# icapmodify –I -120
Temporary capacity available: 0 days, 2 hours,0 minutes(120 minutes TiCAP )
This decreases the amount of TiCAP assigned to the partition by 120 minutes.
Incrementing TiCAP assigned to a partition
The amount of TiCAP assigned to a partition can be increased by using the following command:
icapmodify –I <positive_number>
Sample Output:
# icapmodify –I 120
Temporary capacity available: 0 days, 4 hours, 0 minutes(240 minutes TiCAP )
This increments the amount of TiCAP assigned to the partition by 120 minutes.
Using TiCAP balance to activate cores
The available temporary capacity balance can be used to activate cores using the following
command:
icapmodify –a <number_of_cores> -t
Sample Output:
# icapmodify -a 2 -t
13 cores are intended to be active and are currently active.
Number of cores using temporary capacity: 2
Projected temporary capacity expiration: 07/30/10 02:00:00
