MaxDB turning very slow while executing big transactions

MaxDB turning very slow while executing big transactions

2007-04-25       - By Stefano Ghezzi

 Back
I've a very big transaction which involves one thousand
of insert before commiting everything

At a certain point during the transaction MaxDB
starts to slow down everything and inserts
are processed in a very long time

At the beginning they run in tens of milliseconds, after some
hundreds of inserts they run in tens of seconds and insert
time keep increasing

I see also a kernel process running at 100% cpu and
system with a very high wait on IO.


It seems to me that this could be related to some
kernel configuration parameter to manage transaction
that i need to extend

Any idea?

Thanks in advance

PS: MaxDB 7.5.0.19
