Comments


    

  • There were not a really loop in module DRLPXB10.
The performance problem was caused by a PR Feature provided
by third parts. These feature contains some PR objects like
UPDATE definitions wrong designed. These updates perform a
large use of different Lookup Tables containing more than
100.000 rows. This is in evident contrast with PR specification:

To achieve acceptable performance, lookup tables are read into
storage buffers at the start of processing. This means that the
tables should not be too large. It also means that any changes
to a lookup table resulting from a collect operation do not
affect the result of a lookup before the collect is completed.

CHAPTER 9__, UNDER "Lookup expressions_TOPIC Note__".
