IDC11774I   CURRENT INDEX CISIZE IS cisize, RECOMMENDED MINIMUM INDEX CISIZE IS newcisize

This message indicates the current index CISIZE of the data set, and based on the average compression of the keys in the sequence set it recommends a minimum index CISIZE value. This is a minimum size and may be less than the current index CISIZE. Specifying a CISIZE which is smaller than the recommended minimum CI size is expected to generate unreachable CIs. The minimum value is based on the average key compression and index structure elements of the sequence set and is a value that should ensure that most of the keys for a data CA can be described in an index CI record. The recommended minimum value also represents the current state of the sequence set, the specified CISIZE should also consider future activities such as adding keys of different compression lengths and key deletion which might result in unreachable data CIs in the future. Adding record keys of different compression lengths in the future can require a index CISIZE which is larger than the recommended minimum. If the current index size is smaller than the recommended minimum, a larger index CISIZE may be needed to reduce unused data CIs that are unreachable because the index record becomes full before all data CIs in the CA are represented. Unreachable data CIs describe empty and unused space within the data component which can contribute to unexpected data growth and out of space conditions.This information is provided for CI sizes above and below the recommended value and does not indicate an error.
