As you've excluded glance I can't think of much.. (I also assume you mean MeasureWare as well).. try lsof and tsuc

This requires extensive measurement information and none of the classic HP-UX utilities can provide this information. The only practical way to do this is with Measureware but be prepared for some very large reports. If you monitor all processes, you'll have hundreds to thousands of files to review by size and I/O count. Use sar -v 1 to see how many files are open. Measureware can output the data to a spreadsheet which will make summarizing activity a lot easier.

maybe you can think on a system call that does it?

i want online details like glance but without using it.

thanx.

You want the performance of a Ferrari (glance) by driving a Ford Pinto (sar, vmstat, ...).

The magic bullet IS glance/measureware/perfview. the glance suite is going to provide you better information than sar, vmstat or any other tool. That's the bottom line!
