All master files created to reference DB2 tables on AS/400 automatically get SEGTYPE=S0 parameter. Based on existing documentation, the SEGTYPE parameter is used for Focus files and fixed file formats. Master files are defined with SUFFIX=DB2. What significance does the SEGYPE=S0 parameter have? Is it required? why is it generated automatically?

thanks...

Simply, SEGTYPE indicates the sort order.

S4 = 4 sort keys
SH3 = 3 sort keys High to Low

The RDBMS Knows the keys and indexes and therefore are not needed.

There is much more on this, and I would suggest taking a look at the manual Describing Data With WebFOCUS Language.

hi Waz,

thanks for your reply. The documentation describes your scenario for Focus files. What is the deal regarding DB2 files on the AS400? Not sure that SEGTYPE works the same way for DB2?

any thoughts?

Thanks for your help...rena

From what I understand, it doesn't mean anything for RDBMS's.

The important part is the order of the fields and the Keys attribute in the ACX file.
