Example of a Reclaim Vector

For example, suppose you have two storage classes and you want to specify a reclaim vector for each of them. Storage class one identifies data items that your application does not need to quickly access. Storage class two identifies data items that your application must access quickly.

Table 1 shows how you might define two reclaim vectors (one for each of the storage classes) described as follows:

The reclaim vector for storage class 1 specifies the following: 5 reclaims from storage class 1 and 0 reclaims from storage class 2.
The reclaim vector for storage class 2 specifies the following: 6 reclaims from storage class 1 and 1 reclaim from storage class 2.
The repeat factor specified on the REPEAT keyword is 2. For each of the storage reclaim vectors described above, the system goes through the process twice for reclaims before it deactivates the vector and uses the default.

Table 1. Two Reclaim Vectors
Storage class reclaim vector	Number of reclaims from storage class 1 resources	Number of reclaims from storage class 2 resources	Repeat factor
For storage class 1	5	0	Attempts reclaims as indicated by the vector 2 times.
For storage class 2	6	1	Attempts reclaims as indicated by the vector 2 times.
