Am reviewing performance issues of a conversion process to read data from
many files and write many records (hundreds of thousands or millions of
records). 30 or 40 programs, of which 4 are very complex and taking most of
the time, All RPGIV, all write file as "output", not "update add". About
half write to files allowing null values, and not having errors (using
%nullind).
The process is taking longer to execute than the 12 hr window (their orig
estimate) to get it done - by 2 - 3 times. The pgmr is very experienced (in
RPGIV) so its not simple stuff (but am checking).
Not an option to rewrite at this point, but looking for tips on allocation
of resources.
This is V7R1, single processor power 7+ w 16 gig memory, 1.5Tb local disk.
