6.1.1 Db2 Fast Load measurements  This section describes the results of the performance observations when comparing DRDA  Fast Load with the local Db2 LOAD utility.  The test environment for the workload used the following configuration:  The scenarios compare the performance of the traditional FTP plus local LOAD process  versus loading the data directly from the client by using DRDA Fast Load.  The test cases consist of loading data from 160 data files into a Db2 table that was created in  a table space that is defined with 160 partitions. On the client side, 160 parallel scripts load  the data into each partition. Example 6-2 show the bash scripts that were used for driving the parallel  zload  commands.  In this script, the  zload12a  file is started to run the  zload  command.  The contents of the  zload12a  file is shown in Example 6-3.  Example 6-2 Bash script to drive 160 parallel DRDA Fast Load script Example 6-3 zload command to load a single partition out of 160 partitions In the scalability scenario, 15, 30, and 60 concurrent LOADs were run to measure the  scalability of the DRDA Fast Load. The loads were run from a client machine against different  partitions of the same table in Db2 for z/OS. The scenario consisted of loading 15 internal  format files into 15 partitions, 30 files into 30 partitions, and 60 files into 60 partitions. The  table was empty before the load. Each file consists of data in internal format to be loaded into each partition.  Chapter 6.
