1) We have changed logical names. FREND was an old product that the tools were part of in the late 1980's and early 1990s ( back in V1-3 days). We have changed them to reflect the new company...ie    FREND$xxx$yyy  is now ALI_xxx_yyy.      "FREND" is now "ALI"..."$" is now "_"...a very simple translation. 

2) The number of potential disks in the params files has been increased ( to 999), and the param for this is now slightly different.....DBDISK001 instead of DBDISK01, etc etc. DBDISKs are now resolved all the way to the device. Hence, if two DBDISKs are the same device, the tool now takes this into consideration with regards to  available physical disk space. 

3) Compression default values in the params file have changed to represent the Rdb default. This is different than in previous versions. Check your previous params file for the proper setting or the tool may allocate larger ( or smaller) than expected storage area files. 

4) Vertical & Horizontal partitioning is supported, and requires direct counts of the number of records in each partition. This may increase the time for script generation when running DBTune against a database with large partitioned tables..

5) A single-file Rdb database is created for an interim holding spot for DBTune data. This database is found in the ALI_DBTUNE_SCRATCH directory, and is deleted at the end of the script generation.

6) There is a new logical for the different SQL rules in effect. 

"Databases which have been created using the earlier SQL92 standard, or have been successfully tuned with earlier versions of DBTune,  should consider/test defining the VMS logical ALI_SQL_RULES to “SQL92” prior to running DBTune V6. This is most commonly required when reserved words were used as identifiers (ie column names for example), and were enclosed  in “ ”  when originally defined  (ie using “year” as a column name for example)."

7) Rdb 7.3 now requires a minimum of EV56 on Alpha processors. The same holds for Controller 6.2 in order to be compatible and to utilize the Rdb software library w/out errors.
