Re: collaborative memory management on Linux weekly news
When the VM support is released there will be additional monitor counters; and we do plan on publishing additional results (in addition to what was published on the referenced article and at various conferences). Part of the benefit is not just saved memory, but more efficient management of that memory.

Re: FCP over ECKD performance advantage - why?
It depends. From a response time perspective, the bulk of the difference is dependent on the hardware. FICON/FCP to DS8000 both will likely give similar response time. Processor time, particularly in a virtualized environment will vary significantly. See http://www.vm.ibm.com/perf/reports/zvm/html/520lxd.html In general on system z, FCP has three areas of potential advantage: 1. avoids overhead of converting from block to eckd and back to block oriented in the CU. 2. more I/Os can be executed in parallel (though PAV is a method for ECKD to minimize this advantage) 3. more data can be moved in a single I/O command Workloads are impacted differently by the above. There are also a number of non-performance related differences.

gcc 3.4.6 converting sprintf to strcpy calls causing kernel linkedit failure
I'm _almost_ ready to get a good compile of Linux kernel 2.4.33.3 with
all the developerWorks patches integrated. The last problem is
unresolved references to strcpy in the lcs.c and qeth.c modules. I've
isolated the problem to a single sprintf command in each of them (out of
_many_ that seem fine). The following patches seems to fix it. It
certainly compiles, but I am not sure it is the correct way to go about
it.

I ran into a similar problem when installing WAS 5.1 on an x86 box a while ago also, but I cannot remember just how I fixed it. Hopefully, the bits I can remember will help you proceed. WebSphere ships with a JRE in the installation package, so it should always be able to find a "suitable JVM". However, the JRE shipped with WebSphere 5.1 on x86 did not work properly.The installer would just hang. Yours exits, but the cause might be the same: the JRE is not working. I used the -is:log option of InstallShield, and found that it was trying to get the version string from the JRE shipped with WAS. I copied that JRE out of InstallShield's temporary directory and ran strace on it to find out that it was catching a SIGSEGV somewhere, and its recovery of that looped to cause the SIGSEGV again, thus the hang. What I just can't remember is how I fixed that, but perhaps the above debugging path will get you started. Try to capture the JRE that InstallShield is trying to use and run it with the -version option. You should get something like this: java version "1.4.2" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2) Classic VM (build 1.4.2, J2RE 1.4.2 IBM build cx3901420-20040626 (JIT enabled: jitc)) which is the Java version used by WAS 5.1 on both the s390 and x86 platforms. That is what InstallShield should be looking for. The -is:log output should say that. If the JRE from InstallShield cannot even report the version string (as mine could not), that's when you need to resort to strace to find out what is broken. Sorry I can't be of more help, but I didn't take notes on how I fixed this problem and my memory leaks. :-) If the above gets you a bit further and you post more info, perhaps it will jog my memory. - MacK. - Edmund R.

Re: Fw: Kernel Compilation Failure with gcc 3.4.6
Hi Mark,
as Heiko already mentioned the gcc error message is caused by a bogus
always_inline attribute. Declaring a function as always_inline in the
prototype and not giving gcc the function body at compile time is simply
wrong. However I must say that the gcc message of "sorry, unimplemented"
isn't very helpful here - to my mind a simple error would be the better
choice. This topic has been discussed on the gcc mailing list in 2004 (see
http://gcc.gnu.org/ml/gcc-patches/2004-01/msg01032.html).
They agreed to emit this "sorry" message since the code is syntactically
correct. You get the very same message with gcc 4.1 and 4.2.
> dasd_int.h:493: sorry, unimplemented: inlining failed in call to
> 'dasd_chanq_deq': function body not available
> dasd_3990_erp.c:2999: sorry, unimplemented: called from here
But it looks like a problem to me that gcc isn't very consistent when to
issue that message. You get the message for the following example:
__attribute__ ((always_inline)) void foo ();
static __inline__ __attribute__ ((always_inline)) void bar ()
{
}
a ()
{
foo ();
bar ();
}
But not for:
__attribute__ ((always_inline)) void foo ();
a ()
{
foo ();
}
The code path in gcc which issues the message is not entered when there is
no function which could successfully be inlined. I will discuss this on the
gcc mailing list.

Kernel Compilation Failure with gcc
3.4.6
I'm trying to compile the 2.4.33.2 kernel with gcc 3.4.6, and I'm
getting a compilation error (shown below). The same code compiles with
gcc 3.3.4, so I went looking for a gcc bug. I think

You can prepare another dasd with dasdfmt and fdasd, then use mkswap to create a swap space on a partition you created, and activate it using swapon. All commands have man-pages that explain their proper usage. If you want to use the swap space on the next startup, add the disk to /etc/fstab just like the swap partition you do already use (see "man fstab"). cheers, Carsten -- Carsten Otte has stopped smoking: Ich habe in 3 Monate, 2 Wochen und 4 Tage schon 531,81 Euro gespart anstatt 2.215,90 Zigaretten zu kaufen. -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
swap partition increase
I'm running linux sles9 sp3 on z/vm 5.1 . The person who genned the linux guests partitioned a 3390 as /dev/dasdb1 swap 1020.0 MB /dev/dasdb2 /tmp 1.2 GB . This next line is a my humble opinion. There is some kind of memory leak in the java code written for the apps on these guest. Why you ask? When the guests are started we have ~190 tasks running with 0k swap space used. Now as things get started I would expect some swap space to be used. But as the week wears on the number of tasks creep up (~260-280) and the swap space decreases and never releases. The tasks are not zombies but show 'sleeping'. I know the next statement isn't a permanent fix but I need to know if(and how) I can increase my swap space. Or do I have an option "B" and what that option is and how to impliment that option. again I know the best thing to do is fix the code but that won't happen. thanks Mace __ Do You Yahoo!?
