Java File Handles
Hi,
perhaps you can answer my question.....Smilie

How can I check, how many file handles are used and how can i increase the value for maximum file handles???

You mean 'file descriptors' (FDs) I think. The total number of FDs are kernel parameters. Depending on what UNIX flavor you are running, the kernel documentation and souce code has this info. Some systems are easier than other to reconfigure.

Also, there are formulas to change these parameters because raising or lowering one key kernel parameter effects others (like a balance or scale.... commonly referred to as a design trade-off.)

So, as you know, you can't just make this parameter 100000000000 without seriously impacting (in a negative way) your system performance.
