z/OS Server / PM07633 - Major Performance Improvement for V7 -> V8 migrations
« on: July 15, 2010, 08:30:14 AM »
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.)
