PM07633 - Major Performance Improvement for V7 -> V8 migrations

[Ed_Arnold]

This APAR makes a huge difference.

ERROR DESCRIPTION:                                               
arsdb command import option (-i) performance degradation occurs 
due to frequency of commits. Even though the arsdb import code   
itself does not issue explicit commits, code elsewhere in arsdb 
turns on the ODBC auto-commit setting, a fact that the code to   
do the import was not cognizant of. (The auto-commits don't     
show up in an ODBC application trace.)

Oops - the title is a bit misleading, don't know how to edit it.

This APAR affects H272741, H272841, H27284A .... in other words, if you're migrating from V2 -> V7 it'll improve table load throughput at that release as well.

PROBLEM DESCRIPTION(S):

    *                 using arsdb -i

    * PROBLEM DESCRIPTION: arsdb -i can experience long import     
    *                      times

    * RECOMMENDATION: None.                                       
    ***************************************************************
    arsdb -i was running with the ODBC autocommit enabled.  This   
    caused a commit to be performed after every insert of a row   
    into the table being imported.

This code change provides so much improvement it's been marked HIPER:
