Kind of picking up late. The fist thing came into my mind is I got a similar situation in my db2 luw database and I created a index on concat columns.

Example of my index.

CREATE INDEX CMSDB.IX_CONCAT_POCAT_PONUMBER on CMSDB.POMASTER (CONCAT(pocat, ponumber)) COMPRESS NO INCLUDE NULL KEYS ALLOW REVERSE SCANS
