Hi All, OS: windows 2003 server Database : 10.2.0.2 STANDARD EDITION I have a database that is running in noarchivelog mode and the log files are not multiplexed. I have only 2 drives available for oracle so I have put my redo log files separate from datafiles This database is for conversion purposes and needs to be as fast as the hardware allows me. I am using SQL*loader to load files into this database after which I can do transformations followed by and extraction to the final system. I need enabled constraints (mainly check) so direct load is out of the question I guess. Now when I load my data After a while all 4 250MB logfiles have status active and checkpointing freezes the database. But even if it just loads 1 file, leaving just 1 redo log file active and 1 current, and I manually checkpoint the database this takes a long time during which the database is not responding. I have searched metalink and google but have not found anything usefull relating to this. I have some of the wait events relating to the logfiles listed here and the top wait events for this loader session was actually log file sync WAIT_CLASS#|EVENT|TIME_WAITED|AVERAGE_WAIT 9|log file sequential read|15|0.37 9|log file single write|68|1.67 9|log file parallel write|897575|0.75 2|log file switch completion|742|33.74 5|log file sync|896616|0.75 If you need more information please let me know specific which Brgds Jack
