1 ADAREORG-08/09 ADAREORG Presented by

2 ADAREORG-08/09 ADAREORG A utility for reorganizing the physical structure of compressed or decompressed ADABAS files, and flat files (or tables)

3 ADAREORG-08/09 Uses for ADAREORG Respond to changing requirements –Insert or delete fields anywhere, including PEs –Transform PEs and MUs into flat files –Perform field type conversions –Manipulate sub-fields –Make other changes using field-level user-exits

4 ADAREORG-08/09 Uses of ADAREORG Creation of Test Databases –Select on subfield value –Insert constant values –Limit the number of output records Tuning Aid –Remove defunct fields to save space and to avoid decompressing unused data –Reorder fields and PEs/MUs to speed ADABAS decompression

5 ADAREORG-08/09 ADAREORG Operations

6 ADAREORG-08/09 ADAREORG Features Available for download from the Treehouse website to facilitate fast transmission of new releases, upgrades, and zaps Support for ADABAS V8.x and backwards compatibility with ADABAS V7.x, and V6.x

7 ADAREORG-08/09 ADAREORG Features Features supported: –3/4 Byte ISNs, 4 Byte RABNs, 2 Byte FNRs, and 2 Byte DBIDs –Large alpha fields, up to 16K –191 Periodic Group occurrences –F fields need not be fixed length (restricted to 2 or 4 bytes) –G fields need not be fixed length (either 4 or 8 bytes) –Super-DEs up to 20 fields –NC/NN field options have been added –Variable length fields (i.e., zero) –Additional field-level user-exit invocations per execution
