HP and oracle and informix

Folks, I have a very complicated question. I got the following parameters from someone who told me this would boost performance. The platform is an HP unix system . It are parameters for VXFS (JFS). The idea behingd is that Oracle does enough check , so filesystems check during writing on the filesystem where the data is located physsically can be turned off. The parameters are: nodatainlog nolog mincache=tmpcache convosync=delay What I want to know what are the risks and is it only possible with oracle or also for informix. Wim

Might be worth checking with the guys on comp.sys.hp.hpux -- --------------------------------------- Tony Flaherty aef@mfs.misys.co.uk Analyst Programmer Misys Financial Systems All statements and opinions are my own, Misys don't pay me enough to have opinions on their behalf .
