Output from top:
Box is running 3 instances of oracle.
last pid: 25158; load averages: 4.72, 5.64, 6.30 12:28:49
477 processes: 467 sleeping, 5 zombie, 5 on cpu
CPU states: 80.0% idle, 8.5% user, 3.9% kernel, 7.6% iowait, 0.0% swap
Memory: 14G real, 7447M free, 6834M swap in use, 5846M swap free

Why would swap being used instead of real memory? Could that have been
instructed to used swap ? How to know.

Here is buffer cache, is it too large? how about Shared memory?
sysdef info
292241408 maximum memory allowed in buffer cache (bufhwm)
4294967295 max shared memory segment size (SHMMAX)

SunOS cltsunp01 5.8 Generic_117350-25 sun4u sparc
SUNW,Ultra-Enterprise-10000
14 GB Mem, 28 X 400 MHz CPUs

And there are 3 instances of Oracle 9.2.06. Size of the largest DB is
200 GB
Thanks.

Worth using registers instead of memory locations?
Is there a worthwhile speed boost in using registers to hold variables instead of memory, when the variables will be accessed multiple times anyway? I imagine that since the variables I am talking about are static and frequently accessed, they will remain in cache anyway, and make swapping them into registers a mostly pointless exercise. Am I right?

Is it good to use char instead of int to save memory?
Hi, Is it recommended to use char instead of int for variables that you know never will contain a value larger than 255? A small example follows: #include <stdio.h> int main(void) { //int i = 1; char i = 1; //is this better than previous line? printf("i=%d\n",i); return 0; } What are the pros and cons of using char instead of int when values will not exceed 255?

Live Upgrde 2.1 and Veritas "awareness", and can swap be used of boot build?
I have a Solaris Sparc 2.6 system I wish to upgrade to Solaris 9, but it is currently running Veritas 3.0.3c. The only Veritas listed under Solaris 9 on the www site is Veritas 3.2. I assume Veritas will need to be upgraded first before the OS upgrade? I have read how Live Upgrade 2.1 is more "veritas aware". To what degree is this so? Even more of an issue however, is in using Live Upgrade 2.1. Disk space is virtually non-existent for a separate disk or empty slice. Is there a way to use part/all of the swap slice to build the upgrade environment, when Veritas is being used pre...

physical memory vs. real memory
Hi, in sam (or as well in top) I can see two different parameters, one is called physical memory and the other one is real memory. So far I used these terms equally. I still assume that physical memory denotes to the hardware mem chips I put in the server, but was is real memory? Any idea? Thanks, Jochen Hi The "memory management whitepaper". should give you some information Once it was in /usr/share/doc/mem_mgt.txt; don't know whether this exists in actual versions (And I do not pretend, that I understood it completely ;-) ). As far as I remember real memory is basical...

memory leak in 5.8.2??? #2
I have an application written in Perl/tk that will write a small file (~128 bytes) to disk. At random intervals, the application is unable to write ti the disk. No error message is given, the write file is executed but the trap 'or die...' is not. The OS is RedHat 7.2. I have checked the amount of disk space (~85% in use of a 40GB HDD) and this tells me that it isn't a disk spave issue. If I shutdown and let the server sit for about 20 minutes, then boot it back up, the system will allow files to be written to disk once again. A couple of possible explanations have come up: 1 - Th...

Can I use somehow use CAT5 instead of COAX for SPDIF?
I need to get SPDIF audio into my bedroom from my living room. I was planning to run RG6, but thought that if I could run CAT5 instead, I would have a more future usable piece of cable. Besides, its much easier to handle CAT5 instead of stiff RG6. Can anybody provide any tips?

And I get an "OUT OF MEMORY" Error. I tried using the options memsize 1G and sortsize 750M, but that didn't help I'm using a unix system so I run it with this options from an autorun. if all else fails I will split the input data into 2 and run the program twice. But at first I wanted to see if any one has a solution to this problem. I've read many posts on here related to this topic but couldn't find any to help me. Thanks Unless you are the system admin, the options memsize are not going... references: 2 thresholds instead of one in classification problem with 2 classes Dear friends and experts, In a classification problem with 2 classes, it is sometimes useful to that the machine classifier works with 2 thresholds instead of one: output of <= threshold 1 (object is allocated to class 1) threshold 1 < output < threshold 2 (no allocation of object is made) output >= threshold 2 (object is allocated to class 2) >From a practical point of view, I would simply draw a histogram with the output in both classes and start with the optimal threshold. >From this point, threshold 1 is shifted to the left and threshold 2 is shifted to the right... Traffic Across Wireless Bridge w/ 2 VLANs using 2 Cisco 2950 Switches? I have an environment that has two Cisco 2950 Switches and a Wireless (Tranzeo 5.8Ghz) Bridge than spans two buildings.

Then all the computers plug into the other ports on the Switch. What I'd like to do is create another subnet for a division of our ... Suitable for real use? Hi, I'm interested in Minix, but I have one question that is still on my mind. Is Minix suitable for real work / development and as a general desktop operating system? ..Or is it only good for educational purposes? Thank you, - Steve I think minix is originally developed for education purposes. I guess they're now trying to make it suitable for some general purpose computing. (just my opinion).

SWAP Space Reduced by Itself Hi, Noticed that occasionally the swap device on one of my SUN box (Sloaris 8) will be reduced to just a few MBs rather than the allocated size of 7GB. My qustion here is how can the total swap size be reduced. Pls take note that I am talking about the total swap space, which is the Kbytes, first column of the df -k command. Normally I will need to reboot the server inorder to reclaim back the swap space. Thanks to advise. Rgds.

Using glut......... #2 Hello everyone, I am using GCC through DevC++ & Code Block Studio IDEs. I got libraries "gl" & "glu" with these IDEs. Programs based on these two libs gl & glu are executing well. I want to use "glut" library. So I downloaded glut package and copied it to respective folders i.e. to include\GL\glut.h lib\glut32.lib and %WinDir%\System\glut32.dll then I test a glut program; It complied successfully but while linking it gave me a list of errors. Which setting do I need to change ? If you know, Please guide me to overcome the problem !!! yours Advai...

Using C allocated memory
Hi, I am trying to use C allocated memory from a Fortran code (following from examples given in these threads: http://coding.derkeiler.com/Archive/Fortran/comp.lang.fortran/2008-03/msg00641.html http://www.pgroup.com/userforum/viewtopic.php?t=1764&sid=d0488a2985be743c87cafd20145ad478).
