The reindex command line utility can be used to fix a corrupted appdix.mdx, but it changes the displayed order of a second field, when multiple records with the same policy number are displayed. 1. Respectively rename appidx.dbf, appidx.mdx to appidx1.dbf, appidx1.mdx2. Create a dummy fsisys.ini 3. Execute "db2dbw32.exe /I=fsisys.ini /ST=appidx1 /SD=appidx.dfd /TT=appidx /TD=appidx"
