When PowerExchange executed SQL with a WHERE clause against data for Adabas, Datacom, IDMS, IMS or KSDS, the NRDB optimized reading process discarded a condition .The condition is still used for post-read qualification. PowerExchange cannot process conditions that contain a decimal point character within a constant.
Processing continues, but the skipped condition causes too many records to be read, which causes slower overall processing.
If possible, construct the SQL WHERE clause condition using comparisons on fields that are used in a database key. Database keys do not typically contain integer fields that have scale. This message can be suppressed using the REPORT_UNUSED_OPT_READING_CONDITIONS=N parameter.
