How can I see memory used by Java?
Hi. I'm running the Blackdown 1.2preV2 java on Linux 2.2.12. I've found that I have to use the -mx option to run with 128Mb or so in my application. I'm always curious as to how much memory it's "really" using, and I've found that 'top' will report this pretty well - at least I think so. Memory increases slowly; I get the application to run gc() and it drops, etc. Top's report seems faithful to what I know the application is doing. However a 'ps -l' listing always shows the same amount of memory in use, typically the 128Mb plus a bit more (for code, bss and stuff, I guess). So I'm assuming that java grabs all 128Mb worth at the start, and ps shows that; so what does 'top' report in what seems to be a more realistic portrayl of what Java is actually 'using'?

JDK on Linux....
Hi! , Does JDK1.1.7 for Linux6.1 is built for 32bit linux or 64bit linux?. Does JDK1.1.7 works on boh?. Thanks in advance... Regard Pramila
memory allocation under SMP
Q: would the linux JDK benefit from an SMP-aware malloc/free library? I just saw the announcement of a new version of Hoard (http://www.cs.utexas.edu/users/emery/hoard/) and was fairly impressed by the claims. Perhaps the blackdown jdk is either already using a similar scheme or only allocs in one thread? -mik (disclaimer - I know nothing about Hoard beyond what's on their web page, and even less about standard VM malloc use.) -- Michael Thome ([EMAIL PROTECTED]) -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

jdk-1.2.x plugin for Netscape-Linux ?
Hi guys, How far are we from being able do develop jdk1.2 applets under Linux ? (Right now I can program it and compile it on jdk-1.2pre2, but I have to test it on Slowlaris or Win98) Thanks all really --In GNU we trust. C. Dinh Math.

Re: How can I see memory used by Java?
The two numbers being reported are Virtual Memory (the amount of address space allocated to the process) and Resident Set Size (the amount of the process address space that is occupying physical RAM). When the data space's VM is bigger than its RSS, the difference is paged out to the swap devices, and paged into physical memory as needed. Essentially, RSS reflects how much of the program's address space has been touched recently, as well as the kernel's decision about how to allocate physical memory among processes that need it. If a program needs to regularly touch more memory than it can get RSS from the kernel, it tends to hammer the swap devices.

I don't think that the problem is on the NT side because I've had success in connecting several different NT workstations on multiple ports. Linux isn't allowing the NT box to connect through port 1050 (or any other port for that matter). Isn't there a config file somewhere that will allow remote clients to connect through specific ports? My hosts.deny file is empty.

The hosts.deny file isn't implicated; it's an application-level filter that Java apps doesn't know anything about. Perhaps you've got some kernel-level packet filtering turned on. If you've got a 2.2 kernel, running this as root: /sbin/ipchains --list will tell you if you're doing any packet filtering. There's a comparable /sbin/ipfwadm invocation for 2.0 kernels, but I don't recall the details.
