Overriding or Restoring the Default Reclaim Algorithm: Summary

You use the SET_RECLVCTR request to define and activate or deactivate a reclaim vector that you provide for a specified storage class. When you deactivate the reclaim vector, the system resumes using the default reclaim algorithm.

Each request must specify the storage class to which the request applies. To specify the storage class, use the STGCLASS keyword.

To define and activate a reclaim vector, the request must include the RECLVCTR, REPEAT, and STGCLASS keywords. RECLVCTR defines the vector for the specified storage class. REPEAT, which must specify a non-zero value, defines the number of iterations the system can make through the vector before automatically resuming use of the default algorithm.
To deactivate a vector before the system automatically resumes using the default algorithm, the request must include the REPEAT, and STGCLASS keywords. REPEAT must specify a value of 0. STGCLASS specifies the storage class whose vector you are deactivating. You can omit the RECLVCTR keyword.

There are other keywords that are required and some that are optional. For a description of keywords that are applicable to all IXLCACHE requests, see:
