index builds are very slow

Posted By: DOUGLAS MERRILL
Date: Wednesday, 26 May 2010, at 11:44 a.m.

from Doug Merrill: dmerrill@lakecountyil.gov

Created 950 tables using dbschema.
Disabled, triggers, constraints, and indexes.
Loaded data using load in parallel.
Database size is 200gb.
Enabling the indexes has been running for 48 hours.
Enabling the indexes is still running!
Why are index builds(or enables) so slow?????????????????????????????

# DYNAMIC_LOGS:

# 1 : notify DBA to add new logical logs when necessary. (ON)
# 0 : cannot add logical log on the fly. (OFF)
#
# When dynamic logging is on, we can have higher values for LTXHWM/LTXEHWM,
# because the server can add new logical logs during long transaction rollback.
# However, to limit the number of new logical logs being added, LTXHWM/LTXEHWM
# can be set to smaller values.
#
# If dynamic logging is off, LTXHWM/LTXEHWM need to be set to smaller values
# to avoid long transaction rollback hanging the server due to lack of logical
# log space, i.e. 50/60 or lower.
#
# In case of system configured with CDR, the difference between LTXHWM and
# LTXEHWM should be atleast 30% so that we could minimize log overrun issue.
